The length of a rectangle is 3ft less than twice the width, and the area of the rectangle is 77ft^(2). Find the dimensions of the rectangle

Answers

Answer 1

Let x = width

2x + 3 = length

Area of rectangle is length times width

x(2x + 3) = 77

2x² + 3x = 77

2x² + 3x - 77 = 0

2x² + 14x - 11x - 77 = 0

2x(x + 7) - 11(x + 7) = 0

(2x - 11)(x + 7) = 0

x = 11/2, - 7

Distance/measurements can't be negative so x = 11/2

The length:

2(11/2) + 3

11 + 3

14

Your width is 11/2 feet and your length is 14 feet.

seconds in a day.

Answers

Answer:

There are 86,400 seconds in one day. 60 minutes an hour x 24 hours= 1440 minutes. There are 60 seconds in a day, so you multiply 1440 x 60 which equals 86400 seconds in 24 hours, or one day

There are 86,400 seconds in one day by using the conversion factor method.

To convert the units of time and find how many seconds are in one day, we can use the conversion factor method as shown below:

1 day = 24 hours * 60 minutes * 60 seconds

To calculate the total number of seconds in one day, we can multiply the number of hours, minutes, and seconds together:

1 day = 24 * 60 * 60 seconds

1 day = 24 * 3600 seconds

1 day = 86,400 seconds

Therefore, there are 86,400 seconds in one day .

What is the area Molly needs to paint? Follow the steps to solve this problem.
1. Which surface is shared by the two solids? What are the dimensions of this surface?
The surface that is shared by the two solids is the top of the cube that is the same as the square base of the pyramid.
2. There is another surface that Molly does not need to paint, because it won’t show when she displays the model house. Describe that surface, and explain why it doesn't need to be painted.
She doesn't need to paint the bottom because you cant see the bottom.

Circle the correct answer.
twice the area of the triangle
twice the area of the square
three times the area of the square
the area of the square
4. Find the area Molly needs to paint. Show your work, and be sure to include units with your answer.

Answers

Answer:

Step-by-step explanation:

Part 1) The surface that is shared by the two solids is the top of the cube that is the same that the square base of the pyramid

Part 2) The dimensions of this surface are 6 in x 6 in

Part 3) Molly needs to paint 228 square inches

The picture of the question in the attached figure

Part 1) Which surface is shared by the two solids?

we know that

The surface that is shared by the two solids is the top of the cube that is the same that the square base of the pyramid

Part 2)  What are the dimensions of this surface?

The surface is a square with side length 6 inches

so

The dimensions of this surface are 6 in x 6 in

Part 3) what is the area molly needs to paint?

we know that

The area that Molly needs to paint is equal to the surface area of the cube plus the surface area of the pyramid minus two times the area of the surface that is shared by the two solids

so

therefore

Molly needs to paint 228 square inches
