Answer:
12 over 5, or 2.4
Step-by-step explanation:
I plugged it in my graphic calculator.
The number of years the amount has been in the venture account with 12% interest per year is 4.
<h3>What is compound interest?</h3>
Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.
A sum of $2,500 was deposited in a venture account, which pays 12% compounded per year and it accumulated to $3,950.
Then the number of the years will be
We know the compound interest formula
where
A = Accumulated amount
P = Deposited value
r = rate of interest
t = time
Then we have
Taking log both sides, then we have
Then the number of the years is 4.

Answer:
x = 1, y = 3
Step-by-step explanation:
y = -2x + 6 --- Equation 1
y = 4x - 1 --- Equation 2
Since both (-2x + 6) and (4x - 1) have the same total, y, they are equal.
-2x + 6 = 4x - 1
Isolate the like terms.
6 + 1 = 4x + 2x
Evaluate like terms.
6x = 7
Find x.
x =
x = 1
Substitute x = into Equation 2:
y = 4x - 1
y = 4() - 1
= 4 - 1
y = 3
The Correct Answer is 60.5 Milliroentgens Per Hour
Ex. 62.5 / 3 = 20.8
2 / 20.8 = 10.4
62.5 - 2 = 60.5
