Evan worked 9 hours and
made $85.50. Henry worked 6 hours and made $57.00. Are
these two rates proportional?

Answers

Answer 1
Yes. Set up a ratio:
6/9 = 57/85.5
(6*85.5)/9=57, so it’s true.
Answer 2

Answer:

yes both of them make 9.5 the hour I know this because 85.50 divided by 9 is 9.5 9 times 9 is 81 and .5 times 9 is 4.5 so 81+4.5=85.5 and then 57 divided by 6 is 9.5 as well you can do 6 times 9 and you get 54 and then 6 times 0.5 is 3 and 54+3=57

Step-by-step explanation:

sorry for the long answer but just wanted to clearly explain everything!

Given the two points (3, -1) and (5,3), explain how to write the equation of the line in slope intercept form.

*Write your answer in the form y=mx+b (HINT: you will need to find m and b)


Help quickly!!! I will give brainylist or whatever

Answers

Can you add an image please?

1. To find slope use the slope equation which would be (3 - -1)/ (5-3). The slope is m = 4\2 which is m = 2

2. Plug in one of the points to find the y-intercept. Using the point (5,3) , you would plug this point into the slope intercept equation, along with the slope which was found. 3= (2 x 5) +b. Solving this equation b=-7

3. The slop intercept form is y = 2x - 7

Pentagon PQRST is drawn on a coordinate plane below. what rule best represents a dilation to create pentagon PQRST with a scale factor of 1/2 and with the origin as the center of dilation?

Answers

Answer: [tex](x,y) \to (\dfrac12 x, \dfrac12 y)[/tex]

Step-by-step explanation:

Dilation is a transformation, in which the size of the image gets changed but not shape.

The rule of dilation with scale factor k and wither origin as center of dilation :

(x,y) → (kx, ky)

Here , [tex]k= \dfrac12[/tex] , center of dilation = Origin

Then, the rule best represents a dilation to create pentagon PQRST will be :

One stamp is randomly selected from a 10-by-10 sheet of 100 stamps. What is the probability that the stamp selected is not along an outer edge? Express your answer as a common fraction. Plz answer as soon as possible... thx!

Answers

Ten plus eight teen plus eight
Thirty six

Ten times ten
One hundred

One hundred minus thirty six
Sixty four

1/64 is the fraction and the answer

The required probability of not stamp not along an outer edge is 8/25.

What is a fraction?

A fraction is a numeral that represents a rational number.

Let a and b be two numbers, then their fraction can be represented as a/b.

Given that,

Total numbers of stamp in a stamp sheet of 10 by 10 = 100,

On one edge there would be 10 stamps but on each diagonal there will be 1 stamp common,

Therefore, total number of stamps  on outer edge will be = 9 x 4 = 36

Remaining stamps = 100 - 36 = 64

The fraction value of 64 out of 100 = 64 / 100 = 8 / 25

The required fraction value of stamps is 8 / 25.

A line passes through the point (2,-6) and has an initial value of 6. What is the rate of change for this line?
A. -12
B. -6
C. -1/6
D. 6

Answers

-6
Just did the question

-6

We assume "initial value" means the y-intercept is (0, 6). The rate of change is the "rise" divided by the "run" between the two points.

rise = -6 -6 = -12 . . . . difference of y-values

run = 2 -0 = 2 . . . . . . difference of corresponding x-values

rate of change = rise/run = -12/2 = -6

The rate of change of this line is -6.
