Answer:

6.5

Step-by-step explanation:

First subtract how tall it was 7 1/2 years ago from how tall it is now.

63 1/2 - 18 1/2 =

63 1/2 -  18 1/2 =  45

So in the 7 1/2 years the tree grew 45 feet. To get the average yearly growth for the 7 1/2 year period you have to divide the 45 feet by 7 1/2 years. = 6

It makes it much easier if you change the fractions to decimals.

63 1/2 = 63.5

7 1/2 = 7.5

63.5  ÷  7.5  = 8.46(repeated)7 feet per year so 6.500 rounded

[FIRST TO ANSWER GETS BRAINLIEST] Here is a rectangle ABCD. The length of the rectangle is increased by 10%. The width of the re
erastovalidia [21]
New length = 30x110% = 33cm
new width = 20x105% = 21cm

original perimeter = 30x2 + 20x2
= 60 + 40 = 100
new perimeter = 33x2 + 21x2
= 66 + 42 = 108

increase in perimeter = 108-100 = 8
percentage increase = 8/100 x 100% = 8%

Pie

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We need two points through which the line passes to find the slope:

(0, -4)\\(1,0)

We found the slope:

m = \frac {y2-y1} {x2-x1}\\m = \frac {0 - (- 4)} {1-0} = \frac {4} {1} = 4

So, the equation is of the form:

y = 4x + b

We substitute a point to find "b":

-4 = 4 (0) + b\\-4 = b

Finally, the equation is:

y = 4x-4

Option D
