Answer:
1440 cubic yards
Step-by-step explanation:
There are 3 feet in a yard. Multiply 480 x 3 using the algorithm and you get 1440.
Answer:
=452.16 ft^3
Step-by-step explanation:
Volume of cylinder formula: V=πr^2(h)
Note: Diamater/2=radius
Plug-in: V=3.14(4)^2(9)
=452.16 ft^3
Answer:
x=1, y=-5
Step-by-step explanation:
Given equations are:

In order to solve the equation
Multiplying Eqn 1 by 5 and eqn 2 by 3 and subtracting them
So,
Eqn 1 becomes
15x+50y=-235
Eqn 2 becomes
15x-21y=120
Subtracting 2 from a
15x+50y - (15x-21y) = -235-120
15x+50y-15x + 21y = -355
71y = -355
y = -355/71
y =-5
Putting y= -5 in eqn 1
3x+10(-5) = -47
3x -50 = -47
3x = -47+50
3x = 3
x = 3/3
x = 1
Hence the solution is:
x=1, y=-5
X=90y=70I used the process of elimination.
