Answer:
22 miles per hour
Step-by-step explanation:
we know that
The speed is the ratio of distance by the time
Let
d -----> distance in feet
t ----> time in seconds
s ----> the speed in ft/sec

we have

substitute


Remember that


Convert ft/sec to mi/h

8 is a cube: 2³
27 is a cube: 3³
The expression can be identified as "the sum of two cubes": (2z)³ + 3³.
Answer: Choice C) 10.5
The distance from A to C is 7 units (count out the spaces between the two points, or subtract y coordinates 4-(-3) = 4+3 = 7)
Let AC = 7 be the base of the triangle. You might want to rotate the image so that AC is laying horizontally rather than being vertical.
Now move to point P. Walk 3 spaces to the right until you land on segment AC. This shows that the height of the triangle is 3 when the base is AC = 7.
base = 7, height = 3
area of triangle = (1/2)*base*height
area of triangle = 0.5*7*3
area of triangle = 10.5 square units
