Answer:
$817.60
Step-by-step explanation:
Simple interest has the formula:
Simple Interest = Principal * rate * time
here,
Principal amount is $730
The rate of interest is 3%, which is 3/100 = 0.03
The time length in years is given as 4
We find the interest amount first:
SI = P * r * t
SI = 730 * 0.03 * 4
SI = 87.6
We are asked to find FINAL BALANCE, which is PRINCIPAL + INTEREST
So,
Final Balance = 730 + 87.6 = $817.60
Answer:
9 seconds
Step-by-step explanation:
d=-16t²+vt+h
The water level will be at 0 level (distance = 0)
0 = 16t² - 90t - 486
8t² - 45t - 243 = 0
(t - 9) (8t + 27) = 0
t = 9 or t = -27
since time should be a positive number, so t = 9 second
We are given that Jerry had his cruise control set at 60mi/h for 4 hours.
The rate of change is the second name of slope.
We are given rate of 60 miles per hour.
Thereofore, slope would be just 60.
And because it's keep 60 miles per hour for next 4 hours that is constant for next four hours.
Therefore it would stay positive.
So, we can say
1. Slope = 60
2. Positive.
Answer:
6077
Step-by-step explanation:
An estimate helps you because you round 3.9 to 4 and 5.3 to 5 so then you can give a rough estimation
