Answer:
80pi-60pi
Step-by-step explanation:
To find how much Juan ran, we must find the circumference.
pi *30*2=60*pi (which is how much Juan ran.)
pi*40*2=80*pi (which is how much Miguel ran)
80pi-60pi would be how much farther Miguel ran than Juan.
Answer:
15 In²
Step-by-step explanation:
Area of triangle = 1/2 × base × height
1/2 × 6 × 5 = 15
The answer is J. 1/(x^2-x)
The values of x and y are 0.2 and 0.4 respectively.
<em><u>Explanation</u></em>
The given proportions are.....
and 
From the second proportion, we will get....

Now, we will plug this
into the first proportion. So we will get....

So, the values of x and y are 0.2 and 0.4 respectively.
