Last year, 60% of runners who competed in the Labor Day race finished in 1 hour or less. There were 285 runners who finished the Labor Day race in 1 hour or less. How many runners competed in the Labor Day race?

475 runners competed in the Labor Day race.

Step-by-step explanation:

Given:

Last year, 60% of runners who competed in the Labor Day race finished in 1 hour or less. There were 285 runners who finished the Labor Day race in 1 hour or less.

Now, to find the runners competed in the Labor Day race.

Let the runners competed in the Labor Day race be

Rate of runners who competed in the Labor Day race finished in 1 hour or less = 60%.

Number of runners who competed in the Labor Day race finished in 1 hour or less = 285.

Now, to get the runners competed in the Labor Day race we put an equation:

Dividing both sides by 0.60 we get:

Therefore, 475 runners competed in the Labor Day race.

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
