Jorgen made deposits of $250 at the end of each year for 12 years. The rate received was 6% annually. What's the value of the in
2 answers:
FV = P(
)
Where, FV = Value after 12 years, P= Yearly deposits = $250, r= Rate = 6% = 0.06, n=Number of years = 12 years.
Then,
FV= 250 (
) = $4,217.50
Where, FV = Value after 12 years, P= Yearly deposits = $250, r= Rate = 6% = 0.06, n=Number of years = 12 years.
Then,
FV= 250 (
Answer:
$430
Step-by-step explanation:
We can use the simple interest rate formula to calculate the investment value after 12 years. The formula is:
Where A is the value of the amount after investment, P is the intitial investment, r is the rate and t is the time invested.
Therefore $250 at a rate of 6% for 12 years:
The value of the investment after 12 years is $430

(a) Animals by popularity; Dogs, Cats, Others, Horses.
(b) If 250 students were interviewed, 20 students have other pets.
(c) No, it was incorrect.
Step-by-step explanation:
Step 1; We arrange the different pets in chronological order, from the highest percent to the lowest percent;
1. Dogs - 67%,
2. Cats - 20%
3. Others - 8%,
4. Horses - 1%.
None is not included in this list.
Step 2; If 250 students were interviewed, 8% of those have other pets. So we need to calculate how much 8% of 250 is.
8% of 250 = × 250 = 0.08 × 250 = 20.
So 20 students had other pets.
Step 3; 20% of the interviewed students had cats. If 75 students had cats, we need to equate 20% to the 75 and find out how many students were actually interviewed.
20% × x = 75, 0.2 × x = 75,
x = = 375.
So if 375 students were interviewed, 75 students would have cats. So the estimate of 250 students being interviewed is incorrect.
Answer:
x =
Step-by-step explanation:
x^2 + 8^2 = 9
Simplify the 8^2
x^2 + 64 = 9
Subtract 64 from both sides
x^2 = -55
Take the square root from both sides
x = +/-
Simplify
x =
