What is percentage?
Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, Last semester, 150 out of the 800 students at Jungle Junior High made the Honor Roll.
Now, the percentage is
150/800 ×100
= 18.75%
Therefore, the percent of the students made the Honor Roll is 18.75%.

The equation to determine the amount of left over kitchen shelving paper is; L = 53/4 - (21/2)x.
What is the definition of the mixed fractions?
- A mixed fraction is just a type of fraction that has both a whole number and a fractional part.
- An improper fraction may also be formed from a mixed fraction.
For the given question;
Martha purchased 6 kitchen shelves with shelving paper.
The length of 6 shelves is 1 3/4 feet = 7/4 feet.
Thus, the total length of the 6 shelving papers is 6× 7/4 = 21/2 feet
The corrected width of the shelving paper is 13 1/4 = 53/4 feet.
The equation to defined the left over papers 'L'.
Let number of shelves be 'x'.
L = 53/4 - (21/2)x.
Thus, the equation to determine the amount of left over kitchen shelving paper is; L = 53/4 - (21/2)x.

The correct question is-
Martha is covering kitchen shelves with shelving paper. She has 6 shelves that are each 1 3/4 feet long. She buys 13 1/4 feet of shelving paper of the correct width. Which equation can be used to determine how much paper she will have left over?
The correct expression is 13 1/4 − 6(1 3/4) = S. You take the total amount you have and subtract how much you need, 6 shelves each 1 3/4 feet long.

What is the volume of the rectangular prism?
Let the prism with a length of L, a width of W, anda height of H. Then the volume of the prism is given as
V = L x W x H
A company makes concrete bricks shaped like rectangular prisms. Each brick is 11 inches long, 8 inches wide, and 5 inches tall. Then the volume of each brick will be
V = 11 x 8 x 5
V = 440 cubic inches
If they have used 11,000 cubic inches of concrete, then the number of bricks that they make will be
⇒ 11,000 / 440
⇒ 25 bricks
The number of bricks that they make will be 25 bricks.
More about the volume of the rectangular prism link is given below.

5*8*11=440
To find how many bricks they made divide 11,000 by 440 which is 25
They made 25 bricks

Answer:

Step-by-step explanation:
An angle and its opposite side are known
Sin (of the angle)= opposite/ hypotenuse
The hypotenuse is equal to the length of the ladder, therefore solve the hypotenuse
Sin (32)= 20/ hypotenuse
hypotenuse= 20/ Sin (32)
Sin (32)=0.5299
hypotenuse= 20/ 0.5299
37.74 ft
