Answer:

12 1/2 mins

Step-by-step explanation:

If the teacher has 47 1/2 minutes left, and there are 60 minutes in an hour, all you have to do is 60-47.5 which is 12.5. To change this into a mixed number, we know 5 is half of 10, so it is 12 1/2 minutes. Hope this helped.

A’B’C’ is a dilation image if ABC which is the correct description of the dilation

Sav [38]

Answer:

The dilation is an enlargement

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor

In this problem Triangles A'B'C' and ABC are similar by AA Similarity Postulate

Let

z------> the scale factor

$z=\frac{A'C'}{AC}$

substitute the values

$z=\frac{2+8}{2}$

$z=\frac{10}{2}=5$

The scale factor is greater than 1

therefore

The dilation is an enlargement

PLEASE PLEASE HELP ME OUT! But i ask that you explain how you got your answer and not just give the answer.

ok so first we would do the function d(x) = 3(8)+2

which when solved turns out to be 26

we would then do the function h(x) = 2(26) +7

which when solved turns out to be 59

so he would need 59 dollars for the donuts
