Answer:
14 girls
Step-by-step explanation:
boys : girls = total
5 : 7 = 12
10 : 14 = 24
We need to solve this system
<span>(3x + 2y = 36.50) *5
(2x + 5y = 50.00) *(-2)
15x+10y= 182.5
-4x -10y= -100
11x=82.5
x= 7.50 at the library
</span>2x + 5y = 50.00
<span>2*7.5+5y=50
15+5y=50
5y=35
y=7 at coffee cart
So,
correct answer is
</span><span>C.Percy earns a greater hourly wage of $7.50 at the library.</span><span>
</span>
Answer:

Answer:
3964 in³
Step-by-step explanation:
volume of sphere: V = 4/3 πr³
v₁ = 4/3 x 3.14 x 7³ = 1436
volume of prism: v = Bh B = 15 x 18 = 270 h = 20
v₂ = 270 x 20 = 5400
v₂ - v₁ = 5400 - 1436 = 3964 in³
