The rectangle below has a length of 7 centimeters and a width of 3 centimeters. Three centimeters are subtracted from the length, and c centimeters are added to the width. The area of the new rectangle is 32 square centimeters. What is the value of c?
A. 1 centimeters
B. 3 centimeter
C. 5 centimeters
D. 10 centimeters
Answers
Answer:
C
Step-by-step explanation:
7 - 3 = 4 = Length
3 + c = ? = w
A = 32
32 ÷ 4 = 8 = w
8 - 3 = 5 = number added to width
5 = c
Word explanation:
To find the number added, you have to figure out the length so that you could divide it by area to figure out the width.
So, to do that, you follow what the question said, "Three centimeters are subtracted from the length." = 7 - 3 = l = 4
Then, you move on to figure out the width, so you divide the area by the length = 32 ÷ 4 = 8 = width.
Now that you know the width, you continue to follow what the question said, "C centimeters are added to width."
= 3 (previous width) + c = 8 (new width)
After that, you subtract 8 - 3 to find the amount added to the width and that gives you 5, which is C.
The value of the variable c is 5 centimeters.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
To determine the number added, we have to figure out the length so that we could divide it by area to figure out the width.
"Three centimeters are subtracted from the length means;
= 7 - 3 = l = 4
Then, move on to figure out the width, so we divide the area by the length
= 32 ÷ 4
= 8 width.
Now that we know the width, continue to follow what the question said, "C centimeters are added to width."
= 3 (previous width) + c = 8 (new width)
After that, subtract 8 - 3 to find the amount added to the width and that gives 5, which is C.

Manuel wants to replace the wooden floor at his gym. The floor is in the shape of a rectangle. Its length is 50 feet and its width is 25 feet. Suppose wood flooring costs $8 for each square foot. How much will the wood flooring cost for the floor?
Answers
Answer:
$ 10,000
Step-by-step explanation:
Manuel wants to replace the wooden floor at his gym. The floor is in the shape of a rectangle. Its length is 50 feet and its width is 25 feet.
The gym floor is shaped like a rectangle
Area of a rectangle = Length × Width
= 50 feet × 25 feet
= 1250 ft²
Suppose wood flooring costs $8 for each square foot.
The wood flooring cost for the floor is calculated as
1 ft² = $8
1250ft² = x
Cross Multiply
1250 ft² × $8
$ 10,000
The wood flooring cost for the floor is $10,000

If the radius of the sphere is doubled, the volume would be multiplied by 4. Think of the sphere as a cube instead and if you were to double the sides, the area would be 4 times bigger. Hope this helps! :)

Which side lengths form a right triangle? please help
Answers
In a right triangle, the side that is opposite of the 90° angle is the longest side of the triangle, and is called the hypotenuse. The sides of a right triangle are commonly referred to with the variables a, b, and c, where c is the hypotenuse and a and b are the lengths of the shorter sides.
Joseph concludes that the difference between the longest and shortest lengths is 2 1 2 feet. Marta disagrees and says that the difference is only 1 foot. Who is correct? Use the drop-down menus to show and explain your answer. Is correct because you the greatest and least lengths represented by the , not the number of at the greatest and least lengths.
Answers
The drop downs cannot be viewed.
Answer:
Joseph is correct
Step-by-step explanation:
To obtain the difference between the longest and shortest length of the rope ; all we need to do is find the range of the dot plot ; The value for the range is obtained thus ;
Range = Highest - Least value
Highest value or maximum = 12 feets
Minimum or least = 9 1/2 feets
The Range = difference between the longest and shortest length is : (12 - 9 1/2) feets = 2 1/2 feets

The quadratic function d = –2x^2 + 15 models a skateboarder’s distance, in feet, from the bottom of a hill x seconds after the skateboarder starts moving down the hill. After how many seconds is the skateboarder 8 ft from the bottom of the hill?
Answers
Answer:
After 1.87 seconds the skateboarder is 8 ft from the bottom of the hill.
Step-by-step explanation:
The quadratic function d = –2*x² + 15 models a skateboarder’s distance, in feet, from the bottom of a hill x seconds after the skateboarder starts moving down the hill.
You want to know after how many seconds the skater is 8 feet from the bottom of the hill. That is, with the distance being 8 feet, you want to calculate the time t. Replacing in the expression d by the value of 8 feet:
8=–2*x² + 15
Solving:
8-15 = -2*x²
-7= -2*x²
(-7)÷(-2)= x²
3.5= x²
√3.5=x
1.87= x
After 1.87 seconds the skateboarder is 8 ft from the bottom of the hill.
