Answer:
Step-by-step explanation:
step 1
Convert mixed number to an improper fraction
step 2
Using proportion
step 3
Convert to mixed number
$55,000 - $10,000 = $45,000
$55 - $15 = $40
$45,000 ÷ $40 = 1,125
So, your answer is 1,125
For, future reference, in word problems, highlight the key terms and it may come easier to do them.
Answer:
5t² - 16t + h =0
Step-by-step explanation:
During upward projection the final velocity is zero, and the gravitational acceleration is -10 m/s² (against the gravity).
Therefore; using the equation;
S = 1/2gt² + ut
Where s is the height h, g is gravitational acceleration, and t is the time and u is the initial velocity u, is 16 ft/s.
Thus; h= 1/2(-10)t² + 16t
We get; h = -5t² + 16t
Therefore; the quadratic equation is 5t² - 16t + h =0
