Answer:
D, 4
Step-by-step explanation:
The graph crosses the x-axis 4 different times
You know that $74.92 is the total, and you need to know how much of that total was split between 4 cousins. So that means you have to divide 74.92 by 4. This gives you $18.73.
Hope this helped! ;)
That's a big one. Take it step by step.
-4x+14+20x= 2(10x-3)
Combine like terms.
16x+14= 20x-6
Add 6 on both sides.
16x+20=20x
Subtract 16x on both sides
20=4x
Divide by 4 into both sides.
x=5
Consider it tackled. Kaikers out.

Volume of the pyramid:
V = 1/3 · B · h
B = 8 ft²
tan 30° = height / 7√3
1/√3 = height / 7√3
height = 7 ft
V = 1/3 · 8 · 7 = 18.67 ft³ ≈ 19 ft³
Answer : D ) 19 ft³
