Grade 8- The Pythagorean Theorem
aleksandr82 [10.1K]
1) pythagorean theorem = a2 + b2 = c2
SO:
10^2 + 6^2 = c2
100 + 36 = c2
136 = c2
Diagonal should equal about 11.66 meters

2)  pythagorean theorem = a2 + b2 = c2
SO:12.7^2 + 8.9^2 = c2
161.29 + 79.21 = c2
240.5 = c2
Elevation should equal about 15.1 degrees

A car traveled at an average rate of 51 miles per hour on one highway. It then traveled at an average rate of 71 miles per hour
sergiy2304 [10]

d1 = 51(t)

d2 = 71(8 - t)

d1 + d2 = 508

and now you just have to solve for t.
