Complete question :
A 48 inch board in to be cut into three pieces so that the second piece is twice as long as the first, and the third piece in 3 times as long as the first. If x represents the length of the first, find the lengths of all three
Answer:
Length of first piece = x = 8
Length of second = 2x = 8*2 = 16
Length of third = 3x = 8 * 3 = 24
Step-by-step explanation:
Let :
Length of first piece = x
Length of second = 2x
Length of third = 3x
The total lengtb of board = 48 inches
Hence,
First + second + third = 48
x + 2x + 3x = 48
6x = 48
x = 48 / 6
x = 8
Length of first piece = x = 8
Length of second = 2x = 8*2 = 16
Length of third = 3x = 8 * 3 = 24

Answer:
0
Step-by-step explanation:
The whole thing cancels out because if you move -10x on the left to the right they will cancel out because -10x+10x=0.
Now, you have -10=-10 and so move the -10 to the right and it becomes positive so you get -10+10 which equals 0.

Answer:
315 cm
Step-by-step explanation:
The volumetric flow is:
Q = vA
Q = v (πr²)
Q = (70 cm/s) π (2 cm)²
Q = 280π cm³/s
After 30 minutes (1800 seconds), the volume change is:
ΔV = Q Δt
ΔV = (879.6 cm³/s) (1800 s)
ΔV = 504,000π cm³
The increase in water level is therefore:
ΔV = A Δh
ΔV = πR² Δh
504,000π cm³ = π (40 cm)² Δh
Δh = 315 cm
