Suppose m:angle a =77 degrees what is the measure of a complement of a complement of angle a

1 answer:

6 0

Two Angles are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees.

So measure of angle complentaary to angle a is

X = 90 – 77

X = 13 degrees

Which of the x values are solutions to the inequality 4(2 – x) > –2x – 3(4x + 1)? Check all that apply.

steposvetlana [31]

4(2 - x) > -2x - 3(4x + 1)
8 - 4x > -2x - 12x - 3
-4x + 2x + 12x > -3 - 8
10x > -11
x > -11/10
x > -1.1

Therefore, x = 0 and x = 10 zre solutions to the inequality.

A map is drawn with a scale of 1/2 inch equal to 5 actual miles.if the map distance between two cities is 8 inch's,what is the r

Sunny_sXe [5.5K]

Answer:

The real distance would be 16

Step-by-step explanation:

If the scale is 1/2, that means each distance on the map is half of what the real distance is. So 8 x 2 =16.

8th grade geometry part 3, please explain the steps :)))

Answer: Volume = 97.6

Step-by-step explanation:

Volume of the cone first

V = 1/3 h π r²

h = 0.7

r = 2

V = 1/3 × 0.7 × 2² × 3.14

V = 1/3 × 0.7 × 4 × 3.14

V = 1/3 × 8.792

V = 2.93

Then find the volume of the cylinder if the cone was there.

V = π r² h

r = 2

h = 8

V = 3.14 × 2² × 8

V = 3.14 × 4 × 8

V = 3.14 × 32

V = 100.48

Now you subtract the volume of the cone from the cylinder.

100.48 - 2.93 = 97.55

Rounded to the nearest tenth is 97.6

Hope this was helpful, I know it is a lot to look at but I tried my best.

Also, can I get brainliest? I worked really hard on this.

Find the break-even point for the given cost and revenue equations. Round to the nearest whole unit.. C = 20n + 134,000. R = 160

Novay_Z [31]

The break-even point is when there is no profit and no loss. Given the two equations for cost and revenue, we simply have to equate the two equations to solve for the unknown value, n. This is shown below:

C = 20n + 134000
R = 160n

R = C
160n = 20n + 134000
140n = 134000
n = 957.14

Among the choices, the nearest answer is D. 957.

Answer:

123.4

Step-by-step explanation:

So I added all of the numbers then divide by how many numbers there was so I divided by 5 because I also counted the x as part of it.
