Zoe will have to run 11.9 miles
Given that Zoe's average running speed is about 6 4/5 miles per hour, this is expressed as:
In order to determine the distance he can run in 1 3/4 hour, we can write;
Cross multiply to have:
x * 1 = 7/4 * 34/5
x = 238/20
X = 11.9miles
Hence Zoe will have to run 11.9 miles

Answer:
Step-by-step explanation:
Use a^2 + b^2 = c^2 to get the third side.
a = 12
b = ?
c = 37
a^2 + b^2 = c^2
144 + b^2 = 37^2
144 + b^2 = 1369 Subtract 144 from both sides.
<u>-144 -144</u>
b^2 = 1225 Take the square root of both sides
sqrt(b^2) = sqrt(1225)
b = 35
Perimeter = a + b + c
Perimeter = 12 + 35 + 37
Perimeter = 84
