Answer: 38 feet.
Step-by-step explanation:
The beds have the same dimensions.
Then, to find the number of feet of fabric that Carrie will need to make skirts for both beds, you need to calculate the perimeter of one of them and multiply it by 2. After this, you can make the conversion from inches to feet.
The perimeter of a rectangle can be calculated with this formula:
Where "l" is the length and "w" is the width.
You know that the dimensions of each bed are:
Then you can substitute these values into the formula:
Therefore, the number of inches of fabric that Carrie will need to make skirts for both beds is:
Make the conversion from inches to feet. Then, 456 inches to feet is:
Answer:
D
Step-by-step explanation:
The perpendicular equation can be found by getting the reciprocal of the slope then multiplying it by -1. The slope is the "m" value of y=mx+b; in this case, the slope is .
To find out if it is C or D, you plug in the x value given in the equation (2) and see if it equals the y value given in the equation (-2). C is incorrect, which means that D is correct.
