Answer:
V = πr²(h/3)
Step-by-step explanation:
83.74 = πr²(5/3)
R = 4.00 in
Diamater = 2r = 2 x 4.00 = 8 inches
Set up a proportion
4/12=10/x
cross multiply
120=4x
divide by 4
30=x
10 students would spend $30 on the same school lunch
The system of equations are:
$12p + $3a = $258
a - p = 6
Where:
- a = phone accessories
- p = phone
<h3>What are the system of equations?</h3>
Two linear equations would be derived from the question. The linear equations would be a function of the phones and accessories sold. These equations are known as simultaneous equations and they would have to be solved together in order to determine the required values.

Answer:
i = 77.5°
k = 77.5°
j = 102.5°
h = 155°
Step-by-step explanation:
Since we have an isosceles triangle, we know that ∠i and ∠k are equal. So,
180 - 25 = 2x
155 = 2x
x = 77.5
So m∠i = m∠k = 77.5°
To find m∠j, we use Supplementary Angles:
180 - 77.5 = 102.5°
To find m∠h, we also use Supplementary Angles:
180 - 25 = 155°
