For x = ay - bz:

Add bz to both sides:

ay = x + bz

Divide a on both sides:

y = (x + bz)/a

For xy + yz = 10:

Distribute y from the left side:

y * (x + z) = 10

Divide by x + z:

y = 10/(x + z)

For (ab - ac)/z = x:

Multiply by z on both sides:

ab - ac = xz

Take out a from the left side:

a * (b - c) = xz

Divide by b - c on both sides:

a = xz/(b - c)

13. Round to higher foot, then Solve for volume in cubic yards.
Elenna [48]

Answer:

V = 11.4 cubic yards

Step-by-step explanation:

1 foot = 12 inches

1 yard = 36 inches

1 cubic yard = 46656 cubic inches

change the given values to inches by multiplying by 12

Length = 10'8" , round to higher foot

Length = 11*12  =

Length = 132 inches

Width = 6'4", round to higher foot

Width = 7*12

Width = 84 inches

Depth = 4'

Depth = 4*12 = 48 inches

The volume V = length x width x depth = 132 x 84 x 48 = 532224 cubic inches

divide by 46656 get cubic yards

V = 11.4 cubic yards

A dartboard has a diameter of 18 inches.What are its radius and circumference?
allsm [11]
Diameter of the dartboard as given in the question = 18 inches
Then
Radius of the dartboard will be = 18/2 inches
                                                  = 9 inches
We already know that
Circumference of a circle = <span>2π</span>r
We also know that the value of <span>π = 3.14159
Then
Circumference of the dartboard = 2 * 3.14159 * 9 inches
                                                    = 56.548 inches
                                                    = 56.55 inches
So the radius of the dartboard is 9 inches and the circumference of the dartboard is 56.55 inches. I hope the procedure is absolutely clear to you.
