The height of the higher board above the water surface is 12 feet.

The distance from the high dive to the bottom of the deep end is 24 feet.

<h3>What does division mean?</h3>

Division is the process of dividing a number into equal parts using another number. The sign used to denote division is ÷.

<h3>What is the height of the higher board above the water surface?</h3>

In order to determine the height of the higher board, divide the height of the lower board by 25%.

Height of the higher board = 3 feet / 25%

3 / 0.25 = 12 feet

<h3>what is the distance from the high dive to the bottom of the deep end?</h3>

12 feet + 12 feet = 24 feet

Complete the steps, which describe how to find the area of the shaded portion of the circle. 1. Find the area of the sector by m

Serggg [28]

The area of the sector is found by multiplying the area of the circle and the ratio of the angle subtended (measure of the central angle) by the sector to 360.

<h3>How to find the area of a sector?</h3>

1) The formula for area of a sector of a circle is;

A = (θ/360) * πr²

where πr² is area of circle

θ is the angle subtended by the sector

Thus, we conclude that the area of the sector is found by multiplying the area of the circle and the ratio of the angle subtended (measure of the central angle) by the sector to 360.

2) The area of the triangle formed as part of the segment is subtracted from from the area of the sector.

Solve the System by Graphing:

Marat540 [252]

Answer:

B) One solution
The solution is (2, -2)
The graph is below.

=========================================================

Explanation:

I used GeoGebra to graph the two lines. Desmos is another free tool you can use. There are other graphing calculators out there to choose from as well.

Once you have the two lines graphed, notice that they cross at (2, -2) which is where the solution is located. This point is on both lines, so it satisfies both equations simultaneously. There's only one such intersection point, so there's only one solution.

--------

To graph these equations by hand, plug in various x values to find corresponding y values. For instance, if you plugged in x = 0 into the first equation, then,

y = (-3/2)x+1

y = (-3/2)*0+1

y = 1

The point (0,1) is on the first line. The point (2,-2) is also on this line. Draw a straight line through the two points to finish that equation. The other equation is handled in a similar fashion.
