Mara found the length of time of an investment. The principal of the investment was $4,300, the interest rate was 6.2 percent, and the interest was $2,666. Mara made an error in her work.

I = p r t. 2666 = (4300) (0.062) t. 2666 = (266.6) t. StartFraction 266.6 over 2666 EndFraction = t. 0.1 = t.

Answers

well, 6.2% of 4,300 can't be over half. she has made a calculation error, and the real answer is (this is where the mistake was made) 4,300 * 0.062 (not 6.2, because percents are always divided by 100 to make them into a usable number), which is equal to $266.60.

Answers

Answer:

15,20,25,30

Step-by-step explanation:

f (n) = 5 (n + 2)

Let n=1

f (1) = 5 (1 + 2)

     = 5(3) = 15

Let n=2

f (2) = 5 (2 + 2)

     = 5(4) = 20

Let  n=3

f (3) = 5 (3 + 2)

     = 5(5) = 25

Let n=4

f (4) = 5 (4 + 2)

     = 5(6)=30

Answer:

Six less then a number is equal to ten

Answers

The number is represented by n
n-6=10

To solve, add 6 to each side, giving you n=16

According to the information we can infer that the number is 16. So, 6 - 16 is 10.

What number does complete the operation correctly?

Let's assume the number is represented by 'x'.

According to the given information, six less than a number is equal to ten. This can be expressed as:

x - 6 = 10

To find the value of 'x', we can add 6 to both sides of the equation:

x - 6 + 6 = 10 + 6

This simplifies to:

x = 16

According to the information we can conclude that the number is 16. So, 6 - 16 is 10.
