Answer:

  6.3 years

Step-by-step explanation:

The growth factor each year is 1+19% = 1.19. You want to find the number of years (t) that result in a multiplier of 3 for the account value:

  3 = 1.19^t

Taking logarithms, you get ...

  log(3) = t·log(1.19)

  log(3)/log(1.19) = t ≈ 6.32

It will take a little more than 6 years for Casey/Brad's investment to triple in value.

Can you help me with this question.
HACTEHA [7]

For the scale factor, use the dimensions from similar sides:

Using 18 from the original image you would use 6 from the scaled image.

18 /6 = 3

This means the scaled image is 3 times smaller than the original. Because the scaled image is smaller divide 1 by the scale factor to get 1/3.

Q2:

The scale factor is 1 inch = 12 miles.

Multiply the total inches by 12:

6.5 x 12 = 78 miles.

timofeeve [1]
First of all we will divide 8 by 2 to get the number of full practices in the morning, which is 4. Next divide 7 by 2 to get the number of practices in the afternoon. Although there is a remainder, that remainder is not a full practice session, so we only count the whole numbers which is 3. 
4 + 3 = 7 full practice sessions.
