A skatepark has an area of 6000ft2, a length of 60 ft and an unknown width, find the width of the skatepark

aliya0001 [1]

Answer:

The width of the skatepark is 100ft^2.

Step-by-step explanation:

Total area= 6000ft^2

The Formula for area= L x W (depends on the shape, but in this case that is the formula)

Length= 60 ft

Width = 100

60 x 100= 6000ft^2

Hope this helped!

Explain an example of how taking an amount (for example, $20), decreasing it by 40% and then increasing that amount by 40% does

Likurg_2 [28]

Answer:

See below

Step-by-step explanation:

What we can do is try it out.

20*0.6=12

since 0.6 is left

now we increase 12 by 40, or multiply it by 1.4

12*1.4= 16.8

See what is happening here is that at first when we are decreasing it by 40 percent, we are taking 40 percent of 20. However, when we increase that amount by 40 percent, we are now increasing 40 percent of 20 by 40 percent, or increasing 16 by 40 percent. Therefore, we will not get the original amount.
