Answer: 50.24 m2

Step-by-step explanation:

the fomlua for the area of a cuculal is

A=1/4 π d^2

so...

1/4 * π * 8^2

=50.24

The measure of an angle is five times the measure of its complementary angle. What is the measure of each angle?
GalinKa [24]

Answer:

150 degrees

Step-by-step explanation:

  1. Let the supplement = x  
  2. So the angle you want is 5x  
  3. Then [x + 5x] = 180 because they are supplementary.  
  4. Solving. 6x = 180. Then x = 30.  
  5. So the angle is 5x = 5×30 = 150 degrees

This table represents the number of inches, n, a plant grows after m, months in a new pot.
Yuki888 [10]

Answer: Slope = 5/4

y-intercept = 2

Step-by-step explanation:

We have the table:

Months, m            Plant height in inches, n

0                           2

2                           4.5

4                            7

6                            9.5

We want a linear relationship to represent this table.

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

In this case we can select any pair of points, for example, i will choose the first two:

(0, 2) and (2, 4.5)

Then the slope is:

a = (4.5 - 2)/(2 - 0) = (2.5/2) = 1.25 = 5/4

Then our line can be written as:

y = (5/4)*x + b

To find the value of b, we can replace the values of any of the points in the equation, for example, i will use the point (0, 2) or x = 0, y = 2.

2 = (5/4)*0 + b

2 = b

Then our equation is:

y = (5/4)*x + 2.

Slope = 5/4

y-intercept = 2

avanturin [10]
I think it’s x = 2

-20-12x+10=-34
-10-12x=34
-34+10
-24 divided by 12 = -2
