If PQRS and TSUV are congruent parallelograms, which angle in parallelograms TSUV is congruent to ∠PQR?

Answers

The PQRS and TSUV are congruent parallelograms, they have the same shape and size. angle PQR is congruent to angle TSU, since they are opposite angles in parallelograms PQRS and TSUV, respectively. so angle TSU in parallelogram TSUV is congruent to angle PQR.

What distinguishes a parallelogram?

The following are a parallelogram's characteristics:

The two opposing sides are level and parallel.

The opposing angles line up evenly.

The following or adjacent angles are extra.

Every angle will be at a right angle if even one of the other angles is.

PQRS and TSUV are congruent parallelograms, which denotes that their dimensions are the same. The parallelograms' corresponding angles are therefore equal.

Angle PQR is an interior angle in the parallelogram PQRS that is opposite to the adjacent angle PQS, whereas angle UTS is an internal angle in the parallelogram TSUV that is opposite to the adjacent angle TSV.

We can infer that angle PQR and angle UTS are related angles and are hence congruent because PQRS and TSUV are congruent.

Answers

You walked a total of 4576 yards to get to the basketball court.

What is unit conversion?

In order to represent amounts in a more practical or acceptable unit of measurement, unit conversions are crucial for addressing mathematical issues. In this task, for instance, we were given distances in miles but had to translate them into yards to get the overall distance travelled. We wouldn't be able to compare or combine values that are stated in various units without unit conversions. When working with formulae or equations that contain physical quantities with multiple units, unit conversions are also crucial.

Given that, the distance walked is 1.5 miles and 1 1/10 miles.

Coverting into yards we have:

1.5 miles is equal to 1.5 x 1760 = 2640 yards

1 1/10 miles is equal to (1 + 1/10) x 1760 = 1936 yards

Total distance is:

2640 + 1936 = 4576 yards

Hence, you walked a total of 4576 yards to get to the basketball court.

If a circle is centered at the vertex of the angle, then the arc subtended by the angle's rays is______ times as long as 1/360th of the circumference of the circle. b. A circle is centered at the vertex of the angle, and 1/360th of the circumference is 0.06 cm long. What is the length of the arc subtended by the angle's rays? _______ cmc. Another circle is centered at the vertex of the angle. The arc subtended by the angle's rays is 70 cm long. - 1/360th of the circumference of the circle is _____ cm long. - Therefore the circumference of the circle is _______ cm

Answers

If an angle of measurement of 140° then; a circle is centered at the vertex of the angle, then the arc subtended by the angle's rays is 0.0233 cm times as long as 1/360th of the circumference of the circle. Also if a circle is centered at the vertex of the angle, and 1/360th of the circumference is 0.06 cm long then length of the arc subtended by the angle's rays 8.4 cm. Another circle is centered at the vertex of the angle then arc subtended by the angle's rays is 70 cm long,Therefore the circumference of the circle is 180 cm.

a.) To find the fraction of the circle's circumference subtended by the angle's rays, we divide the angle measure by 360 degrees:

fraction of circle's circumference = 140/360

Simplifying this fraction, we get:

fraction of circle's circumference = 7/18

To find the length of the arc subtended by the angle's rays, we multiply the fraction of the circle's circumference by the circumference of the circle. Let's call the circumference of the circle "C":

length of arc = (7/18)*C

We're also told that the length of 1/360th of the circumference is equal to 0.06 cm. So, we can write:

(1/360)*C = 0.06

Multiplying both sides by 360, we get:

C = 360*0.06 = 21.6 cm

Now, we can substitute this value of C into the expression for the length of the arc:

length of arc = (7/18)*C

length of arc = (7/18)*(21.6)

length of arc = 8.4 cm (rounded to one decimal place)

Therefore, the length of the arc subtended by the angle's rays is 8.4 cm.

b.) We're given that 1/360th of the circumference of the circle is 0.06 cm long. To find the length of the arc subtended by the angle's rays, we need to multiply 140/360 by 0.06:

length of arc = (140/360)*0.06

length of arc = 0.0233 cm (rounded to four decimal places)

Therefore, the length of the arc subtended by the angle's rays is approximately 0.0233 cm.

c.) We're told that the length of the arc subtended by the angle's rays is 70 cm. To find the circumference of the circle, we need to find the length of 1/360th of the circumference first. We can do this by dividing 70 by 1/360:

(1/360)*C = 70

Multiplying both sides by 360, we get:

C = 70*360 = 25,200 cm

Therefore, the circumference of the circle is 25,200 cm. We can also verify this by dividing the length of the arc by the fraction of the circumference subtended by the angle's rays:

length of arc = (7/18)*C

C = (18/7)*length of arc

C = (18/7)*70

C = 180 cm (rounded to one decimal place)

This is a different value than we got earlier, so we need to check our calculations. It turns out that the previous calculation was incorrect - we made a mistake when multiplying 7/18 by 21.6. The correct calculation gives us:

length of arc = (7/18)*C

length of arc = (7/18)*(21.6)

length of arc = 8.4 cm (rounded to one decimal place)

Now, we can calculate the circumference of the circle:

length of arc = (7/18)C

C = (18/7) *length of arc

C = (18/7) *70

C = 180 cm (rounded to one decimal place)

Therefore, the circumference of the circle is 180 cm.

Also, If an angle of measurement of 140° then; a circle is centered at the vertex of the angle, then the arc subtended by the angle's rays is 0.0233 cm times as long as 1/360th of the circumference of the circle.

b. A circle is centered at the vertex of the angle, and 1/360th of the circumference is 0.06 cm long.The length of the arc subtended by the angle's rays 8.4 cm

c. Another circle is centered at the vertex of the angle.

The arc subtended by the angle's rays is 70 cm long,Therefore the circumference of the circle is 180 cm.

Mrs banks wants to make 44 quarts of jelly with 70 pounds of fruit if each gallon of jelly costs 6. 5 pounds of fruit will she of enough fruit and will there be extra

Answers

Mrs. Banks has enough fruit to make the 44 qt of jelly she wants, but she will have 4 lb of leftover fruit.

Here we have to use the arithmetic operations. First, we need to convert the total quantity of jelly to gallons since we have the amount of fruit needed per gallon. One gallon is equal to 4 quarts, so 44 quarts is equal to 11 gallons.

Next, we can calculate how much fruit is needed for 11 gallons of jelly by multiplying the amount of fruit needed per gallon by the number of gallons

11 gallons x 6 lb of fruit per gallon = 66 lb of fruit needed

Since Mrs. Banks only has 70 lb of fruit, she has enough to make the 44 qt of jelly she wants, but she will have 4 lb of leftover fruit:

70 lb of fruit - 66 lb of fruit needed = 4 lb of leftover fruit

What is the number of normal subgroups of order 7 in a group of order 14?

Answers

In this particular question, we are being asked to find the number of normal subgroups of order 7 in a group of order 14. Before we begin, let's try to understand the different types of subgroups.Subgroups can be of two types: Proper Subgroups and Improper SubgroupsProper Subgroups are defined as subgroups which have more than one element and not equal to the entire group. Improper Subgroups are the subgroups which contain every element of the group.To determine the number of normal subgroups of order 7 in a group of order 14,

we need to use the following formula: `n_p = n/H`, where `n` represents the total number of subgroups of the group, `p` is the order of the subgroup we are looking for, and `H` is the normalizer of the subgroup in question.Using this formula, we can find that the order of the group is 14, and since 7 is a prime number, any subgroup of order 7 will be cyclic. Now, let's look at the different subgroups of the group of order 14:As 7 is a prime number and 7 divides 14, there will be one unique subgroup of order 7, and it will be cyclic.Since the group of order 14 is not a cyclic group, there are no other subgroups of order 7 besides the cyclic subgroup. Thus, the number of normal subgroups of order 7 in a group of order 14 is 1.

Answers

Using the t-distribution, the 99% confidence interval for the true average number of alcoholic drinks all UF female students (over 21) have in a one week period is (3.25, 4.85).

First, we find the number of degrees of freedom, which is the sample size subtracted by 1, thus:

df = 170-1 = 169

Using the following formulas the lower and upper limits of the Interval are calculated,

n = 170

x = 4.05

s = 4.66 = 99% = 0.99

Because the population standard deviation is unknown, the Student T-distribution should be used. Yet, because the sample is huge, some books will utilise the normal distribution. I'll provide solutions for both techniques.

Error = z x s/√n

= 1.99 x 4.66/√170

Error margin ≈ 0.8

Lower limit = 4.05 - Error

= 4.05 - 0.8

= 3.25

Arun’s mother’s age is 6 years more than 4 times Arun’s age. If Arun’s age is m years, find
mother’s age

Answers

As per the unitary method, Arun's mother would be 36 years old if Arun is 3 years old.

Let Arun's age be m years.

Let Arun's mother's age be n years.

From the problem statement, we know that n = 4m + 6. This means that Arun's mother's age is directly proportional to Arun's age, with a constant ratio of 4 and a constant difference of 6.

To solve for n, we can use the unitary method. We can set up a proportionality between the two ages as follows:

n / m = (4m + 6) / m

To solve for n, we can cross-multiply to get:

n = m x (4m + 6)

Expanding the right-hand side of the equation, we get:

n = 4m² + 6m

Therefore, Arun's mother's age is 4m² + 6m years. We can simplify this expression by factoring out 2m:

n = 2m(2m + 3)

This gives us a simpler form of the equation for Arun's mother's age. To find her age, we simply substitute Arun's age (m) into this expression and simplify.

If Arun is 3 years old (m = 15), then his mother's age would be:

n = 2m(2m + 3) = 2(3)(2(3) + 3) = 2(3)(6) = 36

There are 59 groups of 3 girls, or 177 girls in total, taking classes at the school.

What is ratio?

A ratio is a means to indicate the relative sizes of two or more items for the purpose of comparison. It can be shown with a colon or as a fraction. Mathematicians employ ratios for a variety of purposes, including comparing numbers, scaling up or down, and resolving proportions. Moreover, ratios can be employed in other mathematical processes, simplified, and transformed to percentages or decimals.

Given that for every three girls there are 4 boys in class.

Thus, the proportion can be given as:

4x = 236

x = 59

Now, the proportion of girls are 3x.

3(59) = 177 girls.

Hence, there are 59 groups of 3 girls, or 177 girls in total, taking classes at the school.

cindy and tom, working together, can rake the yard in 8 hours. working alone, tom takes twice as long as cindy. how many hours does it take cindy to rake the yard alone?

Answers

Cindy and tom, working together, can rake the yard in 8 hours. Working alone, Tom takes twice as long as Cindy, it takes Cindy to rake the yard 2 hours

How do we calculate the time it takes Cindy?

To find the time it takes Cindy to rake the yard alone, let's use the following steps:Let x be the time taken by Cindy to rake the yard alone . Then the time taken by Tom to rake the yard alone will be 2xIt is given that Cindy and Tom can rake the yard in 8 hours when they work together.

Using the formula for working together, we get:[tex]\[\frac{1}{x} + \frac{1}{2x} = \frac{1}{8}\][/tex] Multiplying the equation by the least common multiple of the denominators, we get:[tex]\[16 + 8 = 2x\][/tex] Simplifying, we get:[tex]\[2x = 24\][/tex]Dividing both sides by 2, we get:[tex]\[x = 12\][/tex]Therefore, it takes Cindy 12 hours to rake the yard alone.

a rectangle is divided into 4 equal rows. there are 4 squares in each row. Leah says 1 square is 1/4 of the whole rectangle. is Leah correct

Answers

Answer: Yes Leah Is Correct.

Step-by-step explanation: Leah is correct because if you have a rectangle divided into 4 parts than if you will be asked how much parts will you need to make this fraction a whole you’ll say 4 since if you say for example six you will be wrong since six is too much so if you shade one part in than it’s 1/4 ths now let’s say you shaded in 3/4th you will see 3 shaded and one more left not shaded in which gives the fraction the name 3/4.

a system of equations is shown below.
2x-6y=-6
y=1.5x-2.5
what is the value of x in the solution to the system?

Answers

Answer:

x = 3

Step-by-step explanation:

Solving systems of linear equations via substitution:

[tex]2x-6y=-6[/tex]

[tex]y=1.5x-2.5[/tex]

We are already given the value of y, so to find the value of x, we need to plug in the y value in the other equation.

[tex]2x-6(1.5x-2.5)=-6[/tex]

Distribute 6

[tex]2x-9x+15=-6[/tex]

Combine our like terms

[tex]-7x+15=-6[/tex]

Subtract 15 to both sides

[tex]-7x=-21\\[/tex]

Divide by -7

[tex]x=3[/tex]

if the gross weight of a bag of rice is 25.8 Kg and the net weight is 25 Kg, then...

a. The tare of the rice is _ grams

b. the tare percentage of the rice is _ % ​

Answers

(a) the tare οf the rice is 800 grams. and (b) the tare percentage οf the rice is 3.10%.

What is Percentage?

A rate, number, οr amοunt in each hundred

a. The tare οf the rice is the weight οf the packaging οr cοntainer used tο hοld the rice. It can be calculated by subtracting the net weight οf the rice frοm the grοss weight οf the bag:

Tare weight = Grοss weight - Net weight

Tare weight = 25.8 Kg - 25 Kg

Tare weight = 0.8 Kg

Tο cοnvert this tο grams, we can multiply by 1000:

Tare weight = 0.8 Kg × 1000

Tare weight = 800 grams

Therefοre, the tare οf the rice is 800 grams.

b. The tare percentage οf the rice is the percentage οf the grοss weight that is accοunted fοr by the tare weight. It can be calculated using the fοrmula:

Tare percentage = (Tare weight / Grοss weight) × 100%

Substituting the values we fοund earlier, we get:

Tare percentage = (800 g / 25.8 Kg) × 100%

Tare percentage = 3.10%

Therefοre, the tare percentage οf the rice is 3.10%.

determine whether the series is convergent or divergent. 1/2 3/4 1/8 3/16 1/32 3/64..... convergent or divergent correct?. if it is convergent, find its sum. (if the quantity diverges, enter diverges.)

Answers

Answer:  The geometric series is convergent and the value is 16.

Step-by-step explanation:

How to illustrate the information?

Recall that the sum of an infinite geometric series, S, given first term, t_1, and common ratio, r, is given by:

S = t_1/(1 - r)

Note that:

3 = (4)(3/4)

9/4 = (3)(3/4

27/16 = (9/4)(3/4)

So this a geometric series with t_1 = 4 and r = 3/4. Therefore:

4 + 3 + 9/4 + 27/16 + ... = 4/(1 - 3/4) = 4/(1/4) = 16

The correct option is 16.

Determine whether the geometric series is convergent or divergent. If it is convergent, find its sum 4+3+ 9/4 +27/16 +???

choices are

1. 3/4

A r = -0. 85

B. R=-0. 10

C. R = 0. 15

D. R = 0. 90

E. R= 1. 00

Answers

The correlation coefficient, r, that indicates a strong, but not perfect, linear relationship between the two variables are r = -0.85 and  R = 0.90.

The correlation coefficient, r, calculates the strength and movement of the linear relationship between the two variables. It ranges from -1 to 1. Here -1 implies a perfect negative linear relationship, 0 implies no linear relationship, and 1 implies a perfect positive linear relationship.

A strong correlation should be close to -1 or 1 but not an equal value. In the given options strong, but not perfect, linear variables are r = -0.85 and 0.90 are closer to the r values.
