The formula for simple interest is A = P(1+rt)
Where P is the principal ( amount of money deposited)
R is the interest rate
t is the amount of time
A is the total of the principal and interest.
Using the information given in the problem:
A = 4200(1+0.0325*3)
A = 4200(1 + 0.0975)
A = 4200(1.0975)
A = 4609.50
Now subtract the principal from the total to find the amount of interest:
4609.50 - 4200 = 409.50
Amount of interest = $409.50
We know that
<span>sec a = 5/4
</span>sec(a)=1/cos(a)
then
cos (a)=1/sec(a)
cos (a)=1/(5/4)=4/5---> is positive because the function cos is positive in IV quadrant
the answer is cos(a)=4/5
Answer:
If there are 1500 students in your school then 960 students would enjoy watching TV
Step-by-step explanation:
Step 1: We know that 64% of kids aged from 11 to 15 enjoy watching TV and there is 1500 students in your school
Step 2: We now want to find 64% of 1500, we can rewrite 64% as 0.64. We multiple 1500 by 0.64 to find out how many students enjoy watching TV
0.64 x 1500 = # of students who like watching TV
960 = # of students who like watching TV
Therefore out of 1500 students, 960 would enjoy watching TV
2 it is 2 I hope it is right
