Answer:she need to do at least 3 hours of babysitting.

Step-by-step explanation:

you subtract how much she already has, 3$ from 25.50 and then you divide how much she makes in one hour of babysitting by how much money she needs so 22.50/7.50=3

Answer: Theresa needs to babysit for 3 hours

Step-by-step explanation:

Given that theresa has $3 while she needs $25.50, and makes $7.50 per hour, find the number of hours she needs to work to make the balance she needs.

First, we find the difference between what she has and what she needs= $25.50 - $3

=$22.50

Then, to get the balance she needs, we divide $22.50 by $7.50

=22.50/7.50 = 3hours

Theresa needs to babysit for 3 hours

Which best explains why this triangle is or is not a right triangle?
erastovalidia [21]

Answer:

<h2>This triangle is a right triangle:</h2><h2>36² + 15² = 39².</h2>

Step-by-step explanation:

If a ≤ b <c is the length of the sides of a right triangle, then:

a^2+b^2=c^2

We have

a=15\ in,\ b=36\ in,\ c=39\ in

Check the equality:

L_s=15^2+36^2=225+1296=1521

R_s=39^2=1521

L_s=R_s

It's a right triangle.

Determine which relation is a function.
lutik1710 [3]

Answer:

A

Step-by-step explanation:

One easy way to determine if a coordinate is a function or not is to look at the number in the x's place only. There should not be the same number on the x's side for a different pair.

Every pair has a different number on the x's side, which is why A is the only possible answer.

The fraction models below represent two fractions of the same whole. How much of the Fraction 5 over 8 is in the Fraction 1 over
IrinaVladis [17]

To find how much of 5/8 is you would need to divide 1/2 by 5/8:

X = (1/2) / (5/8)

When dividing fractions, you reverse the second fraction and multiply:

X = (1/2) x (8/5)

X = 8/10

Simplify:

X = 4/5
