Answer:
24 pages per hour
Step-by-step explanation:
72 pages = 3 hours
To find the rate of pages per hour, divide both sides by 3.
72/3 = 24, 3/3=1
24 pages per 1 hour, 24:1
Answer:
x = - 7
Step-by-step explanation:
( x + 139 ) and 132 are vertically opposite angles.
Vertically opposite angles are equal,
x + 139 = 132
x = 132 - 139
x = - 7
Step-by-step explanation:
speed = distance/time
speed = 871÷13
speed = 67 mph
distance = speed x time
distance = 67mph X 9hrs
distance = 603 m
Since
h(x) = g(f(x)), h'(x) = g'(f(x))×f'(x) (Chain rule).
Setting x=3 we get
h'(3) = g'(f(3))×f'(3)
Plugging in values we get
h'(3) = g'(4)×7
h'(3) = 2×7
h'(3) = 14
