I think that Devon swam at least 35 minutes each day for 5 days because if he exercised 225 minutes and each day he walked for 10 minutes then if you divide 225 by 5 you get 45 so every day he exercised 45 minutes and since he walked for 10 minutes you subtract 10 from 45 which gives you 35 so he swam for 35 minutes.
Answer:
0.64 seconds
Step-by-step explanation:
In the equation provided:
h = −16t2 + 4t + 4
h is the height of the ball and t is time. Since we want to find the time when the ball touches the floor, then height is 0. This leaves us with the equation
-16
+ 4t + 4 = 0
This is a quadratic equation can be solved with the following formula:
where a=-16
b=4
c=4
Solving for t we will find two different results:
Since time can't be negative, we discard t2 and choose t1.
Since it is required to answer in the nearest hundredth, we round the result to t=0.64 seconds.
We are given that each share will receive a dividend equal
to 56.25. In this problem, we should have been given the total number of shares
that PRH has so that we can know the dividend. Anyway, the formula to calculate
the dividend is:
<span>Dividend = 56.25 * (Number of Shares)</span>
Answer:
720,051,900
Step-by-step explanation:
it rounds up to 720,051,900 because 5 tells you to round up
Original price was $234.95
49% marked down = $234.95 *49 / 100 = $115.13
So now the sale price = original price - price of 49% marked down
sale price = $234.95 - $115.13 = $119.82
Answer: sale price of a DVD player having a red tag marked down by 49% should be $119.82
