H=0
Therefore:
144t-16t²=0
t (144-16t)=0
We have two equations:
1)
t=0 (when the ball is released)
2)
144-16t=0
-16t=-144
t=-144 / -16=9 (this is the time )
Answer: the ball hit the ground in 9 s.
Answer:
$10.56
Step-by-step explanation:
Cross multiply and divide!
if the total cost is $176, multiply by the % of sales tax and divide by 100 (100%)
176 multiplied by 6% = 1,056
1,056 divided by 100% = $10.56
Answer:
133
Step-by-step explanation:
$3500 - $1500 = $2000
2000/1500 ×100
=1.33 × 100
=133%
