Answer:
(a). $1465.42
(b). $214.58
Step-by-step explanation:
We have been given that installment Buying TV Town sells a big screen smart HDTV for $600 down and monthly payments of $30 for the next 3 years. The interest rate is 1.25% per month on the unpaid balance.
(a) To find the cost of the TV, we will use monthly payment formula.
, where,
R = Periodic payment,
P = Loan amount,
i = Monthly interest rate in decimal form,
n = Number of total payments.
We know that total cost of TV would be equal to down payment plus amount of loan that is:
Therefore, the total cost of the TV would be $1465.42.
(b). First of all, we need to find total amount paid in 3 years by multiplying amount of each monthly payment by 36 (3 years equal to 36 months).
To find the total amount of interest paid, we will subtract amount of loan from total payment.
Therefore, the total amount paid in interest would be $214.58.
A). Pi m
Explanation:
Arc length formula:
Arc length = (Ø/360°) * 2*Pi*r
Ø = given angle (degrees)
r = radius
Plug given numbers in:
(45°/360°)* 2* Pi * 4
This will give you the answer of Pi
1. 1.5 and 3.5
2. both equations because they share these particular points
Answer:
5/27
Step-by-step explanation:
I wrote it as a fraction, but the explanation is, if you're finding out how many who don't play instruments, you first need to find out who many do play instruments, so you add the numbers together.
10+5+7 = 22
So the probability that you'll pick one who does play an instrument would be 22/27 (because 22 out of the 27 pupils play an instrument.) But remember that's not what it's asking us for.
You have to subtract 27 - 22 to get the pupils who don't play instruments, you get 5, so the probability is 5/27 (5 pupils out of 27 don't play instruments.)
To put this in a percent, just divide the top number by the bottom number and move the decimal 2 places over, you get 18.5% or 19% both answers are correct depending on rounding.
When there is a cubed fraction you have to multiply the top fraction by itself 3 times. So you would do 6x6x6 which is 216. Then for the squared fraction so the same, so 5 x 5 which is 25.
So then you get 216/10 x 25/9, in which you would multiply both the numerator and denominator and get 5400/90, put 5400 / 90 to see if it is a no decimal number, in which it is, and it is 60.
The answer is 60
