Answer:

9 hours

Step-by-step explanation:

If she makes $ 20 for each car, washing 9 cars in 3 hours would get $ 180.

So she will need to work 9 hours 180 + 180 + 180, washing 9 cars in 3 hours and would get $ 540. This is enough to buy her phone and she will have a surplus of $ 120.

In summary she must work 9 hours

Hope this helps you, please give me the brainliest

A building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18π meters.
Whitepunk [10]

Answer:

A=81\pi\ m^{2}

Step-by-step explanation:

Step 1

Find the radius of the circular cross section

we know that

The circumference is equal to

C=2\pi r

we have

C=18\pi\ m

substitute and solve for r

18\pi=2\pi r

simplify

18=2 r

r=9\ m

Step 2

Find the area of the circular cross section

The area of the circle is equal to

A=\pi r^{2}

we have

r=9\ m

substitute

A=\pi (9)^{2}

A=81\pi\ m^{2}

If point A is located at (-3,-1) and there are 10 points between A and B, what could be the possible coordinates for point B?
Nataly [62]

Answer:

Step-by-step explanation:

By drawing the point (-3,-1) in the coordinate plane we find the graph shown below. Since there are 10 points between points A and B, we need to start at point A and then we have to move 11 units either to the right, to the left, up, or down .

1. MOVING TO THE RIGHT:

From point A, move 11 units horizontally to the right to come to point B:

(-3+11, -1) = (8, -1)

2. MOVING TO THE LEFT:

From point A, move 11 units horizontally to the left to come to point B:

(-3-11, -1) = (-14, -1)

3. MOVING UPWARD:

From point A, move 11 units vertically upward to come to point B:

(-3, -1+11) = (-3, 10)

4. MOVING DOWNWARD:

From point A, move 11 units vertically downward to come to point B:

(-3, -1-11) = (-3, -12)

So this are the basic movements you can get to find point B. You also can move diagonally upwards or downwards  in whose case you would find other four points. The graph below shows a red point which is A, and the other points are in black color and represent B.
