Answer:
11.66
Step-by-step explanation:
c² = a² + b²
c²= 6² + 10²
c²= 136
c= √136
c= 11.66 ( to two decimals)
Use the midpoint formula
(-6 + 0 ) ÷ 2 , (-3 + 3) ÷ 2
M = ( -3 , 0) which lies on the x axis
Deandra completed the first 6 problems at a rate of 3 problems per hour and the last 12 at a rate of 4 problems per hour.
6 problems ÷ 2 hours = 3 problems per hour
12 problems ÷ 3 hours = 4 problems per hour
