Answer: A. 30
Step-by-step explanation:
We will plug the value of x, 15, into the given expression. Then, we will use the order of operations, also known as PEMDAS. View attached if you need a review.
5² + (x / 3)
5² + (15 / 3)
25 + (5)
30
A. 30
4.) 180-25 = 155 a straight line cuts the circle in half (i.e 180 degrees) then subtract out the 25.
Answer:
B. $25,069
Step-by-step explanation:
An interest of 6% per year, compounded monthly it means that he earns 6/12% = 0.5% of what he has invested every month.
If he invests x money what he will have the first month will be :
Money = x*(1+0.005)
The next month:
Money' = Money*(1+0.005) = x *(1+0.005)(1+0.005) = x* (1+0.005)^2
Therefore in this type of interest the formula is:
Money = x*(1+r)^n
Where:
x is the money invested the first time
r is the interest
n is the number of periods
For this problem:
x = what you have to find
r = 0.005
n = 3 years (1 period is 1 month) then the period is 36 months
Money = 30000
Replacing:
30000 = x * (1+0.005)^36
x = 25,069
