Answer:
B.15
12 x 12 = 144
9 x 9 = 81
144 + 81 = 225
225 square root is 15
If it is a right triangle
Step-by-step explanation:
I=k/d^2
4=k/d^2 and 1=k/64 so if we divide the first by the second we get:
4/1=(k/d^2)/(k/64)
4=(k/d^2)*(64/k)
4=64/d^2
d^2=64/4
d^2=16
d=4 meters
30 mph for 0.5 hrs = 15 miles
80 mph for 2 hours = 160 miles
160 +15 = 175 miles total
You set them both equal to 180 and solve for x so your answer will be 140
