Answer:
18 and 72
Step-by-step explanation:
the smaller part can be assigned as x while the larger will be 4x. Both numbers need to add up to 90, giving the equation: 4x+x = 90
Solve:
4x+x = 90
5x = 90
x = 18
4x = 72
The number of seconds that the ball will hit the ground will be 6 seconds.
<h3>What is kinematics?</h3>
It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
A ball is thrown vertically upward with an initial speed of 96ft/sec. Its height after t seconds is given by
h = - 16(t - 3)² + 144
Then the number of seconds that the ball will hit the ground will be
When the ball is on the ground, the height of the ball is zero. Then we have
0 = - 16(t - 3)² + 144
16(t - 3)² = 144
(t - 3)² = 9
t - 3 = 3
t = 6

E = number of books on Economy
s = number of books on Sociology
so the order on August 1st looks like 15s + 10e = 4300
and the order on August 15th looks like 1s + 3e = 800
