The amount of money each one will make at the end of the day is equals to $21.775.
As per given in the question,
Amount of money earned earned by two friends per hour = $6.50
Total hours spent for baby sitting each day = 6.7hours
Total amount earned by both the friends per day = 6.50 × 6.7
= $ 43.55
Amount of money earned by each one = 43.55 ÷ 2
=$ 21.775
Therefore, the amount of money each one will make at the end of the day is equals to $21.775.

Answer:
3
Step-by-step explanation:
AD/AB = AE/AC
8/10 = 12/AC
AC = 12(10/8) = 15
EC = 15 - 12 = 3
Answer:
Step-by-step explanation:
For part a :
The circumference of the circle is given by the formula 2πr. We are given r so we double r and put it next to pi :
C = 2×π×r = 2×π×8 = 16π
For part b :
The area of a circle is given by the formula πr². We are given r so we square r and put it next to pi :
A = π×r² = π×8² = 64π
For part c :
The area of a square is given by the formula a² where a is the side length. This question requires an extra step as we don't have the length of the square. But we know that the diameter of the circle will be equal to the side of the length. The diameter of a circle is given by the formula 2r : so
D = 2r = 2×8 = 16
So the area of the square will equal :
A = 16² = 256

The standard form: Ax + By = C
y = 90 - 15x <em>add 15x to both sides</em>
<h3>15x + y = 90</h3>
