Answers

Answer:

B.

Step-by-step explanation:

The smiley face has a radius of 8 centimeters.

We need to find the area of the smiley face.

The formula to find the area of a circle is:

A = [tex]\pi[/tex]r²

A = (3.14)(8)(2)

A = (25.12)(2)

A = 50.24

The area of the smiley face would be 50.24 square feet.

The picture includes solving for x and the angle measurement for all. Since angle 2 and 7 are equal you able to set those equations equal to each other to solve for x.

alan would take 5 hours to build the wall of a house, and gavin would take 7 hours to build it alone. when they work together, they talk a lot, and their combined output decreases by 26 bricks per hour. working together, they build the wall in 4 hours. how many bricks are in the wall?

Answers

Answer:

96 bricks

Step-by-step explanation:

Alan does 1/5 of the job in an hour. Gavin does 1/7 of the job in an hour

Together, 12/35 of the job should be done in an hour. In [tex]2 \frac{11}{12}[/tex] hours, the work should be done.

rate at 4 hours=[tex]2 \frac{11}{12}[/tex]*(normal speed-26)

To clarify, x=the normal rate

4 hours(normal rate-26)=[tex]2 \frac{11}{12}[/tex](normal rate)

4(x-26)=[tex]2 \frac{11}{12}[/tex]x

Answer:

The answer is 23 because they have to add up to 90-kai :)

Step-by-step explanation:

So, ∠a + ∠b = 90°

67° + ∠b = 90°

∠b = 90° - 67°

∠b = 23°

Answer:

The measure of ∠b is 23°.

Step-by-step explanation:

Complementary angles are angles that add together to always be 90°. The problem gives us this information at the start:

∠a + ∠b = 90°

∠a = 67°

You can apply this information to the equation by getting the problem of:

67° + ∠b = 90°

To solve this equation you simply rearrange the terms, and subtract 67 from 90:

90° - 67° = ∠b

After rearranging the terms and subtracting 67 from 90 you are left with the following result:

∠b = 23°
