Answer:

degree measure of arc AB = 120°

length of arc AB = 40π/3 in.

Step-by-step explanation:

arc AB has the same measure as its central angle.  So, arc AB = 120°

120 is 1/3 of 360, Therefore, the length of arc AB is 1/3 of the circumference.

Therefore, the

length of arc AB = 1/3πd =  1/3π(40) =  

                            = 40π/3 in.

Use a geometric formula to solve the problem. A rectangle has a width of 4 centimeters and a perimeter of 26 centimeters. Find t
AURORKA [14]

The length is 9.

The formula to find the perimeter of a rectangle is

2L + 2W = P.

2L + 2(4) = 26.

2L + 8 = 26.

2L + 8 (-8) = 26 (-8).

2L = 18.

2L/2 = 18/2.

L = 9.

Wegnerkolmp or someone please help me with this question about slope....
NNADVOKAT [17]

Answer:

The slope is -3/4

Step-by-step explanation:

We need two points to find the slope

We have one point at (0,5) and we have one point at (4,2)

We can use the slope formula

m = (y2-y2)/(x2-x1)

   = (2-5)/( 4-0)

   = -3/4

The slope is -3/4

After 5.75 hours, Kyler had finished painting 62.5% of his house. He needs to paint a total of 4,000 square feet on his house. A
MissTica
First, we are going to find the painted area of his house. We know that the total area he needs to paint is 4000 square meters, so 4000 is the area of this house. Now, to find the 62.5% of that area, we are going to multiply it by \frac{62.5}{100}:
Painted area= (4000)(\frac{62.5}{100})=2500

Now, to find <span>rate, in square feet per hour, we are going to divide the painted area by the number of hours: 
Rate=</span>\frac{2500}{5.75} =434.78

We can conclude that Kyler paints at a rate of 434.78 square feet per hour.

Find the exterior angle of angle c.
Bingel [31]

Answer:

Step-by-step explanation:

This triangle is a polygon. By definition, all the exterior angles of ANY polygon add up to equal 360 degrees. So we add up all the exterior angles and solve for x. That's the first step.

7x - 2 + 9x - 31 + 4x + 33 = 360

Combining like terms gives us

20x + 0 = 360 or simply

20x = 360 so

x = 18

In order to find the value of the angle exterior to angle C, we sub 18 in for x:

7(18) - 2 = 124

What formula should I use for this?
mr_godi [17]
If they're asking for the nth term, you should use n in your formula, ie.,

a(n) = 6000 * 0.5ⁿ

However, the first term is when n=1, so your formula should really be:

a(n) = 6000 * 0.5⁽ⁿ⁻¹⁾

Then the 8th term is 46.875
