Why is it important to be careful of the order of the two letters used when naming a ray?

Answers

Answer 1

Answer:

Because one letter represents an endpoint and the other doesn't.

Step-by-step explanation:

Ray AB starts at endpoint A and goes through point B and then on, indefinitely.

Ray BA starts at endpoint B and goes through point A and then on, indefinitely.

They 'point' in opposite directions.

Answer:

Apple Pie cost $8

Lemon Meringue Pie = $15

Step-by-step explanation:

Creating some variables:

A = apple pie

L = lemon meringue pie

We have two equations:

11A + 1L = 103

11A + 12L=268

You can use elimination or the substitution method to solve. I will be using substitution method.

Solve the first equation for L:

11A + 1L = 103

subtract 11A to both sides

L = 103 - 11A

Plug this into the second equation

[tex]11A + 12(103-11A) =268[/tex]

distribute the 12

[tex]11A + 1236 - 132A = 268[/tex]

combine the A and subtract the 1236

[tex]-121A = -968[/tex]

Divide -968 by -121

A = 8

Next plug this 8 back into one of the two original equations above:

[tex]11(8) + 1L =103[/tex]

[tex]88+L=103[/tex]

subtract 103 by 88

L = 15

Answer:

[tex]A=8[/tex], [tex]L=15[/tex]

Step-by-step explanation:

For the sake of time Apple pies will be represented by [tex]A[/tex] and Lemon will be represented by [tex]L[/tex]

Based on the information given it is clear that:

[tex]11A+1L=103[/tex]

[tex]11A+12L= 268[/tex]

We can rearrange the first equation to solve for [tex]A[/tex], in terms of [tex]L[/tex]

[tex]11A+1L=103[/tex]

subtract [tex]1L[/tex] form both sides

[tex]11A=103-L[/tex]

Now let's input this into the second equation to solve for [tex]L[/tex]

[tex](103-L)+12L=268[/tex]

combine like terms

[tex]11L+103=268[/tex]

subtract [tex]103[/tex] from both sides

[tex]11L=165[/tex]

divide both sides by [tex]11[/tex]

[tex]L=15[/tex]

Now input  this value into the first equation for [tex]L[/tex]

[tex]11A+15=103[/tex]

subtract [tex]15[/tex] from both sides

[tex]11A=88[/tex]

divide both sides by [tex]11[/tex]

[tex]A=8[/tex]

Chase plans to buy a new car and determines he can budget $725 monthly for four years. His bank is offering an 8 25% annual interest rate What is the maximum loan he can afford to stay in his budget? Use the formula, A = (p[(1 + r/n) ^ m - 1])/(1/n * (1 + r/n) ^ N) , where Pis the monthly payment, the annual interest rate, nis the number of times interest is compounded in one year and is the number of years.

Answers

Answer:

$29555.20

Step-by-step explanation:

Given that:

P = $725

r = 8.25% = 0.0825

n = 12

t = 4 years

From the given formula:

[tex]A = \dfrac{P{(1+\dfrac{r}{n})^{n*t}-1 } }{\dfrac{r}{n}(1+ \dfrac{r}{n})^{nt}}}[/tex]

[tex]A = \dfrac{725{(1+\dfrac{0.0825}{12})^{12*4}-1 } }{\dfrac{0.0825}{12}(1+ \dfrac{0.0825}{12})^{4\times 12}}}[/tex]

[tex]A = \dfrac{725{(1.3894-1 )} } { 0.006875 \times 1.3894 }[/tex]

A = $29555.20

Write the equation of the line that passes through the point (4,-2) and has a slope of
-1/2
y = -1/2x + 4
y = -1/2x - 4
y = -1/2x
y = -1/2x + 3

Answers

Answer:

y=-1/2x

Step-by-step explanation:

y-(-2)=-1/2(x-4)

y+2=-1/2x+2

y=-1/2x

The equation of a line is written as y = Mx + b where m is the slope and b is the y intercept.

Replace y and x with the given point and m with the given slope to solve for b:

-2 = -1/2(4) + b

Simplify:

-2 = -2 + b

Add 2 to both sides:

B =0

The equation becomes: y = -1/2x

The side length of 12 in A corresponds to a side length of in B. What is the perimeter of Quadrilateral B? The perimeter of Quadrilateral B is units.

Answers

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

Dilation is the increase or decrease in size of a figure. If a figure with point A(x, y) is dilated by a scale factor of k, the new location is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.

a) The scale factor from Quadrilateral A to Quadrilateral B = smallest side length of side B / smallest side length of side A = 2 / 6 = 1/3

Scale factor = 1/4= 1 / 3

The side length of 6 in A corresponds to a side length of 2 in B

Side length of B that corresponds with side length of 9 in A = scale factor * 9 =  1/3 * 9 = 3

The side length of 9 in A corresponds to a side length of 3 in B

Side length of B that corresponds with side length of 12 in A = scale factor * 9 =  1/3 * 12 = 4

The side length of 12 in A corresponds to a side length of 4 in B.

c)  perimeter of Quadrilateral B = sum of side lengths of quadrilateral B = 2 + 3 + 3 + 4 = 12 units

Annie has 4 1/2 feet of rope what is the greatest number of 3/4 foot pieces that annie can cut from the rope

Answers

Answer:

6

Step-by-step explanation:

4 1/2 divided by 3/4 is 6. so 6 pieces

The greatest number of 3/4 foot pieces that Annie can cut from the rope

is 6.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Annie has 4 1/2 feet of rope.

Therefore, The greatest number of 3/4 foot pieces Annie can cut can be obtained by dividing the length of the total rope by the length of each piece which is,

= (4 1/2)/(3/4).

= (9/2)×(4/3).

= 36/6.

= 6.

So, 6 pieces are possible.

A certain statistic bˆ is being used to estimate a population parameter B . The expected value of bˆ is equal to B . What property does bˆ exhibit? The sampling distribution of bˆ is normal. The sampling distribution of b hat is normal. A The sampling distribution of bˆ is binomial. The sampling distribution of b hat is binomial. B The sampling distribution of bˆ is uniform. The sampling distribution of b hat is uniform. C bˆ is unbiased. B hat is unbiased. D bˆ is biased.

Answers

Answer:

C bˆ is unbiased.

Step-by-step explanation:

In statistics, the sampling distribution showcases the distribution of obtained values by the statistics in all possible sample sizes of the same population. A statistic that estimates a population parameter is termed to be an unbiased estimator if the mean of such distribution appears to be equal to the true value of the estimated parameter.

Thus, from the aforementioned, the property exhibited by b- is unbiased.

d is biased

Step-by-step explanation:

The expected value of d is not D

The property where the expected value of d is D is called unbaisedness, hence d is biased

Between these two numbers, it is a 20% increase.

The solution is, the previous salary is $40910.

What is division?

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

The total salary is $45000

Divide 10% by 100 to express the value as a decimal: 10/100= 0.1

Let x represent the previous salary.

If the previous salary was increased by 10% this means that they calculated the 10% of X and added it to the salary for the increase, symbolically:

x+0.1x=45000

1.1x=45000

x= 45000/1.1

x= 40909.09≅ $40910

Hence, The solution is, the previous salary is $40910.
