Answer:

The answer to your question is:

1 golf ball = $0.75

1 can of tennis balls = $1.25

Step-by-step explanation:

Data

5 dozen golf balls for $45.00

2 dozen cans of tennis balls = $30.00

Golf

              # of golf balls = 5 x 12 = 60

                            60 balls ---------------  $45

                               1 ball -----------------   x

                   x = 1x 45/60 = $0.75

Tennis

             # of cans of tennis balls = 2 dozens = 24 cans

                          24 cans --------------------- $30

                             1 can ----------------------   x

                  x = 1 x 30 / 24 = $1.25

lana [24]

Answer:

cost of the pool per cubic meters = $5

Step-by-step explanation:

The rectangular pool has a dimension of 30 m by 20 m by 2 m. To know the cost of the pool per cubic meter we have to calculate the volume of the pool . Then divide the total cost of the pool by it volume.

volume of the rectangular pool = length × height × width

volume of the rectangular pool = 30 × 20 × 2

volume of the rectangular pool = 1200  m²

The cost of installation is $6000 . The volume of the pool is 1200 cubic meters.

cost per cubic meters = total cost of installation/volume

cost per cubic meters = 6000/1200

cost of the pool per cubic meters = $5

8/7 divided by 5/8.
maksim [4K]

Answer:

64/35

Step-by-step explanation:

To divide fractions, multiply the first fraction by the second fraction's reciprocal.

The reciprocal of a fraction is just the top and bottom number switched.

So the reciprocal of 5/8 would be 8/5.

Now, you can multiply 8/7 by 8/5.

This gives you 64/35.

And that's it!

A 40-foot pipe is cut into three sections. The longest section is three times as long as the shortest, and the middle-sized sect
PtichkaEL [24]

Answer:

P=40

a + b + x = P

a = 3x    

b = x + 5

substitute for b & y

3x + (x+5) + x = 40

Step-by-step explanation:

longest section 1 = a

mid length section 2 = b

shortest section 3 = x

P=40

a + b + x = P

a = 3x    

b = x + 5

substitute for b & y

3x + (x+5) + x = 40

5x + 5 = 40

5x = 35

x = 7

b = 12

a = 21
