No 2/3 of $21 is $14 so 6x14 is $84 less than $110
H=-t^2+95
The y intercept here is 95, and it represented from where the boy threw the ball.
If he threw it from 95 ft above the ground, the best answer for where he is is on a bridge.
His backyard is at 0 ft (sea level). An underground cave is below sea level. A ladder is probably not 95 ft.
Final answer: D
To find out the cyclist's average speed you simply have to divide 50.0km
by 2.5 to find the answer. Therefore the cyclist's average speed is
20.0 km an hour.
