Answer:

w=67°

Step-by-step explanation:

First you solve for x. 12x+11=x. X would be 1. Then you plug in 1 for x and add the w to the equation. 12(1)+11+w=90. after solving that you will get the total for w. which should be 67°

Answer:

First, we need to find how many books there are in each group;

If we look at group 1, they have 18 books.

If we look at group 4, they have 9 books. (We got this because they have 6 whole books, and they have half of a those 6 books which is 3 books in the other book symbol, so combined: 6 + 3 = 9)

18(group 1) - 9(group 4) = 9, group 1 read 9 more books.

Answer:

y=[tex]\frac{1}{2}[/tex]x-8

Step-by-step explanation:

To solve this, you have to use the formula [tex]\frac{x_{2} -x_{1} }{y_{2} -y_{1}}[/tex] to find the slope.

[tex]\frac{0+4}{-8-0}[/tex] = 4/-8 = -1/2

so the slope is -1/2

Now, you plug your values into the formula y=mx+b

m = slope = 1/2

b = y-intercept = -8

so the final formula is y=[tex]\frac{1}{2}[/tex]x-8

Explanation:

Think of "eighths" as the name of a coin type.

The fraction 5/8 means "5 eighths" which we can think of as "5 coins".

Similarly, 1/8 can be thought of as "1 coin" because of 1 in the numerator.

We have two coins of the same type (both "eighths") which means we can combine the coin counts to get 5+1 = 6 coins total.

In other words, 1/8 + 5/8 = (1+5)/8 = 6/8

This is why we add the numerators but keep the denominators the same. If the denominators were different, then we cannot combine the fractions until we get them to the same denominator (such as the LCD).

Having different denominators is like adding apples to oranges. Unless we can somehow get them to the same unit, then adding wouldn't make much sense.

---------------------------

After adding, we need to reduce the result.

The numbers 6 and 8 have the common factor 2.

Divide each by this common factor.

You can write it like this if you wanted:

[tex]\frac{6}{8} = \frac{6 \div 2}{8 \div 2} = \frac{3}{4}[/tex]

Or in short,

[tex]\frac{6}{8} = \frac{3}{4}[/tex]

If you cut a pizza into 8 slices, and eat 6 of them, then it's the same as eating 3 out of 4 total slices. That's one visual way to represent the fraction 6/8 turning into 3/4.

Explanation:

The angles marked with a single arc are one pair of congruent angles forming one "A" of "ASA".

The other "A" is the angles marked with double arcs.

The "S" refers to the sides between those said angles. These sides overlap perfectly so we have a shared side, meaning they must be the same length (refer to the reflexive property).

This is why the triangles are congruent by the ASA (angle side angle) congruence theorem. One triangle is a reflected version of the other. The mirror line being that shared overlapping side. Congruent triangles are like twin identical copies.

"inscribed" means the four corners (vertices) of the square are on the circle.

The diagonal of the square is the diameter of the circle. Use special right triangles or pythagorean thm to find the side length of the square in terms of r. Use Area formula for a square:

The expression 2/3a -7+7/18a-5 1/6 is an illustration of fractions

The simplified expression of 2/3a -7+7/18a-5 1/6 is 19/18a  -73/6

The expression is given as:

2/3a -7+7/18a-5 1/6.

Collect like terms

2/3a -7+7/18a-5 1/6 = 2/3a + 7/18a-7-5 1/6.

Express mixed fractions as improper fractions

2/3a -7+7/18a-5 1/6 = 2/3a + 7/18a - 7 - 31/6.

Evaluate the sum and difference

2/3a -7+7/18a-5 1/6 = 19/18a  -73/6

Hence, the simplified expression of 2/3a -7+7/18a-5 1/6 is 19/18a  -73/6

Answer:

1/6

Step-by-step explanation:

There are 4 primes. So the probability for the first draw is 4/9. Since the card is not replaced, the second probability is 3/8. 3/8 * 4/9 is 12/72, which simplifies into 1/6.

Answer:

1/6

Step-by-step explanation:

There are 4 possible primes: 2, 3, 5, 7

First card has 4/9 probability of being a prime. Second card has 3/8 probability of being a prime(since 3 prime cards left and 8 total cards left because we do not replace the first card). 4/9 * 3/8 = 1/6.

Another way to do this is using combinatorics. C(9,2) = 36 ways to choose 2 distinct cards, C(4,2) = 6 ways to choose two of the "prime" cards. 6/36 = 1/6.

Based on the calculations, the speed of the dog is equal to 8.44 m/s.

Given the following data:

To calculate the speed of the dog:

Speed can be defined as the distance covered by an object or living organism per unit of time. Thus, speed can be measured as meter per seconds.

Mathematically, speed is given by this formula;

[tex]Speed = \frac{distance}{time}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Speed = \frac{135}{16}[/tex]

Speed = 8.44 m/s.

[tex](-3, 5)[/tex]

Step-by-step explanation:

Isolate x from the first equation:

[tex]x=\frac{11-4y}{3}[/tex]

Now, substitute it in  the second equation:

[tex]\begin{bmatrix}2\cdot \frac{11-4y}{3}+y=-1\end{bmatrix}[/tex]

This gives you:

[tex]\begin{bmatrix}\frac{22-5y}{3}=-1\end{bmatrix}[/tex]

So, you conclude: y = 5

Next, we substitute y = 5 into [tex]x=\frac{11-4y}{3}[/tex]

So, we get:

[tex]x=\frac{11-4\cdot \:5}{3}[/tex]

Then:

[tex]x=-3[/tex]

Finally, we have to put it into the coordinate form:

[tex](-3, 5)[/tex]

The sequence a_n = -2 - 51n is an arithmetic sequence

The 11th term of the sequence is -563

The nth term of the sequence is given as:

a_n = -2 - 51n

Substitute 11 for n to calculate the 11th term of the sequence

a11 = -2 - 51 * 11

Evaluate the product

a11 = -2 - 561

Evaluate the difference

a11 = -563

Hence, the 11th term of the sequence is -563

Step-by-step explanation:

Answer:

the first : all real numbers

Step-by-step explanation:

the domain is the interval or set of all valid values for x.

reflecting the graph over the x-axis simply means to multiply the original function by -1.

that does not change the domain in any case. it only changes the range (the interval or set of possible y values).

so, the domain is the same as for the original function : all real numbers.

An Algebraic Expression that models the situation is [tex]4750+p-c-d+r[/tex]

Step-by-step explanation:

Beginning balance of Jennifer=$4750

Now she deposits a paycheck = p

So, New balance = 4750+p

Now she writes a check = c

Remaining balance = 4750+p-c

Now she writes a check = d

Remaining balance = 4750+p-c-d

Now refunded some money (r) for returning a pair of shoes she bought.

New balance = 4750+p-c-d+r

Hence  an Algebraic Expression that models the situation is [tex]4750+p-c-d+r[/tex]
