Answer:
72 runners
Step-by-step explanation:
Total runners = 360
20% of the total runners are in the 35-39 age bracket.
<em>We need to find number of runner in this age bracket.</em>
<em>Which tells us that this number is simply 20% of the total, or 20% of 360.</em>

How to find percentage of number?
We convert percentage to decimal and then multiply it with the other number.
Converting percentage to decimal requires us to divide by 100. So:
20% = 20/100 = 0.2
Now,
0.2 * 360 = 72
Hence,
72 runners are in the 35-39 age bracket
Answer:
<h3>90 remainder 159</h3>
Step-by-step explanation:
Start by calling the shortest side
. We then know that the longer leg (call it
) is 7 feet longer i.e.
. We also know that the hypotenuse,
is 1 foot more than twice the short leg i.e.
. We now have 3 unknowns but only 2 equations to solve them. Luckily we know this is a right triangle so we can use the Pythagorean Theorem as our third equation:
Substituting known values:
This is now an equation in one variable and can be solved algebraically for
. Back-substitution can then be used for the other sides.
