Increased enrollment =9%
Last enrollment=3900
Current enrollment=9%of3900+3900
=9×3900/100+3900
=351+3900
=4451
4 3/8 = (4*8 + 3) / 8 = 35/8
3 1/4 = (4*3 + 1) / 4 = 13/4
Answer:
10%
Step-by-step explanation:
What we will do is apply the present value formula that would be as follows:
PV = P1 / (1 + R) + P2 / (1 + R) ^ 2 + ... + Pn / (1 + R) ^ n
Where VP is the present value, P would be the payment in each corresponding year and R what we are looking for, the interest rate.
Replacing we have the following values:
150 = 55 / (1 + R) + 133 / (1 + R) ³
We have a cubic equation that here is very complex to answer so we are going to use the symbolab tool.
Next we can see how it calculates the value of R step by step.
https://es.symbolab.com/solver/step-by-step/150%20%3D%2055%20%2F%20%5Cleft(1%20%2B%20R%5Cright)%20%2B%20133%20%2F%20%5Cleft(1%20%2B%20R%5Cright)%20%C2%B3
The result is that R equals approximately 0.09976, therefore the interest rate is 9.976%, or rounding 10%
tv-sets are rated by the screen size and the screen size comes from the length of its diagonal.
so a 57" TV has a 57" diagonal.
Check the picture below.
