A) 31%

B) 31%

For the first problem, we know that 25 out of 80 tokens are black. To find the percentage all we have to do is divide 25 by 80, which equal 0.31. To convert this to percentage form, you move the decimal two places to the right, giving you 31%.

And for the second problem you do the same thing. Divide 5 by 16, giving you 0.31. Convert that into percentage, also giving you the percent of 31%.

Joe made a scale drawing of the community pool in his town.

Effectus [21]

Answer:

The length of the pool is 28 meters and the width of the pool is 10.5 meters.

Step-by-step explanation:

In the scale drawing of Joe, the community pool has (length : width) = 8 : 3

Let the actual length of the pool is 8x meters and the actual width is 3x meters.

Now, given that the actual pool has a perimeter of 77 meters.

So, 2(8x + 3x) = 77

⇒ 22x = 77

⇒ x = 3.5
