=2
Answer:
2586810 m³
Step-by-step explanation:
To find the volume of a pyramid, we find the area of the base multiplied by the height, then mulitplied by 1/3:
V = 1/3Bh
Since the base is a square, the area of this is found by the side length squared, making our formula
V = 1/3s²h
V = 1/3(230)²(146.7)
V = 1/3(52900)(146.7)
V = 1/3(7760430)
V = 2586810

Answer:
The amount earned by Josie was $13.75 and the amount earned by her brother was $16.25
Step-by-step explanation:
Let
x ----> amount earned by Josie
y ---> amount earned by her brother
we know that
------> equation A
-----> equation B
Solve the system by substitution
Substitute equation A in equation B
solve for y
Find the value of x
therefore
The amount earned by Josie was $13.75 and the amount earned by her brother was $16.25
