Answer:

He is 62.72 inches tall now

Step-by-step explanation:

the twelve over 100 is the percentage, he increased by 12 percent. and the x over 56 is the new value (x) over the old value. We get 6.72 so we add that to 56 to get 62.72.

In 1999, the share price for General Motors stock was $144 per share but has been declining at an average rate of 14% per year.
vodomira [7]

Answer:  $5.22  (in the year 2021)

========================================================

Explanation:

The year 2021 is 22 years after 1999 since

2021 - 1999 = 22

That means we'll plug x = 22 into the equation given to us

P = 144*(0.86)^x

P = 144*(0.86)^22

P = 5.21588994768589 which is approximate

P = 5.22 rounding to the nearest cent

The share price is about $5.22 in the year 2021.

This assumes that the 14% decline keeps happening year after year; however, in reality, stocks are more complicated and fluctuate more randomly if anything.

Find the perimeter of the triangle in inches.
madam [21]

Answer:

58 inches

<u>Step-by-step explanation:</u>

Perimeter means the sum of length of all sides of a figure.

So, the perimeter of this triangle would also be the sum of the length of its sides.

It has 3 sides.

19 in, 16 in and 23 in.

So, its perimeter equals 19 + 16+ 23

which equals 58 inches!

So, the perimeter would be 58 inches.!
