10. Plot and connect the points to form a rectangle. Then find the length, width, and area of the rectangle.

stellarik [79]

The length of the rectangle is 4

The width of the rectangle is 3.

The area of the rectangle is 12 square units.

Explanation:

Given that the coordinates of the rectangle are A(3,0), B(0,0), C(0,4), D(3,4)

We need to determine the length, width and area of the rectangle.

<u>Length:</u>

After plotting the coordinates in the graph, it is obvious that the length of the rectangle is 4.

<u>Width:</u>

After plotting the coordinates in the graph, it is obvious that the width of the rectangle is 3.

<u>Area of the rectangle:</u>

The formula to determine the area of the rectangle is given by

$Area=length \times width$

Substituting the values, we have,

$Area=4\times 3=12$

Thus, the area of the rectangle is 12 square units.

Lucas has five buttons in a container. Each button is a different shape. There is a star, an oval, a hexagon, a circle, and a he

Readme [11.4K]

Part A: There are five buttons in all in all in the given item. The item above can be answered through the fundamental principles of counting.

There are 5 items to choose from during the first pick. Because the shape can be returned and picked again, there are also 5 items to choose from in the second pick. Multiplying them,
n = 5 x 5 = 25
Therefore, the sample size for the compound event is equal to 25.

Part B: The same concept can be used in this part of the item; however, instead of 5 there are 6 buttons to choose from.
n = 6 x 6 = 36

Hence, the sample size of this picking process is 36.

Sylvia can work at most 15 hours per week at her part-time job. Last week she worked 12 hors and earned $84. She hopes to earn m

Mandarinka [93]

Answer:

14.28 < h < 15

She can and would need to work 14.28 hours.

Step-by-step explanation:

To find how many hours she needs to work to earn $100, we need to know how much she is paid per hour. This amount is x because it is unknown. So 12 hours at x rate equals 84. This is 12x=84 so x=$7 per hour.

To earn a 100, she will earn $7 a hour but not work more than 15 hours. So we write the equation 100=7h where h is number of hours. Solve and h = 14.28. So Sylvia must work 14.28 < h < 15 to earn 100.
