Jared sells square frames of various sizes made of wood. To find the area of a frame, Jared uses the formula A = s^2 - (s - 2w)^2, where s is the length of a side of the frame and w is the width of the frame.
Part B.) Find the area of a frame that measures 20 inches on each side and has a width of 3 inches
Part C.) Jared charges 18 cents per square inch for his frames. How much will he charge for a frame that measures 16 inches on each side and has a width of 2 inches?
Answer:
B.204 square inches
C.2016 cents
Step-by-step explanation:
We are given that Jared sells square frames of various sizes made of wood .To find the area of a frame ,Jared uses the formula
[tex]A=s^2-(s-2w)^2[/tex]
Where s=Length of a side of the frame
w=Width of the frame
B.We are given that length of each side=s=20 inches
Width of frame=w=3 inches
Substitute the values in the above given formula
Then, we get
A=[tex](20)^2-(20-2\times 3)^2[/tex]
[tex]A=400-(20-6)^2[/tex]
[tex]A=400-196=204 [/tex]square inches
Hence, area of frame=204 square inches
C.We are given that
Cost of 1 square inch=18 cents
Length of each side of frame=s=16 inches
Width of frame=w=2 inches
Substitute the values in the given above formula
Then ,we get [tex]A=(16)^2-(16-2\times 2)^2[/tex]
[tex]A=256-(12)^2[/tex]
[tex]A=256-144=112[/tex] square inches
Cost of 112 square inches=[tex]112\times18[/tex]=2016 cents
Hence, he will charge for a frame =2016 cents
The rectangle below has an area of x^2-144 square meters and a length of x+12 meters. What expression represents the width of the rectangle?
The expression for the width of the rectangle is W = ( x - 12 )
What is the Area of a Rectangle?The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
We can use the formula for the area of a rectangle to find an expression for its width:
Area = length × width
The length of the rectangle is given as x + 12 meters, and the area is given as x² - 144 square meters.
We can substitute these values into the formula and solve for the width:
x² - 144 = (x + 12) × width
To solve for the width, we can divide both sides of the equation by x + 12:
width , W = (x² - 144) / (x + 12)
W = ( x + 12 ) ( x - 12 ) / ( x + 12 )
W = ( x - 12 )
Hence , the expression that represents the width of the rectangle is given by W = (x² - 144) / (x + 12) = ( x - 12 )

Find the mean of the integers 5, -15, 7, -13, 1
A mean is an arithmetic average of a set of observations. The mean of the integers 5, -15, 7, -13, 1 is -3.
What is Mean?A mean is an arithmetic average of a set of observations. it is given by the formula,
Mean = (Sum of observations)/Number of observations
The mean of the given integers can be written as,
Mean = Sum of observations/Number of observations
= [5 + (-15) + 7 + (-13) + 1]/5
= (5 - 15 + 7 - 13 + 1) / 5
= -15/5
= -3
Hence, the mean of the integers 5, -15, 7, -13, 1 is -3.

Which umber is greater? Square root of 220 or 14 3/4?
The number square root of 220 is greater than that of 14 3/4.
Given are two numbers.
The square root of 220 and 14 3/4.
We have to find which number is greater.
We know that :
14 3/4 = 14 + 3/4 = 14.75
Now,
14² = 196
15² = 225
So the number 220 lies between 196 and 225.
So √220 lies between 14 and 15.
Since 220 is closest to 225 which is the square of 15, the square root os 220 is more close to 15.
√220 ≈ 14.8
Hence √220 is greater.

To find a baseball pitcher's earned run average (ERA), you can use the formula Ei = 9r, in which E represents ERA, i represents the number of innings pitched, and r represents the number of earned runs allowed. Solve the equation for E. What is a pitcher's ERA if he allows 25 earned runs in 54 innings pitched? If necessary, round your answer to the nearest hundredth. The equation for E is E = . If a pitcher allows 25 earned runs in 54 innings, then the ERA = .
Answer: ERA = 4.17
Step-by-step explanation:
1. First, you need to identify the data you get from the sentence.
Earned runs: 25 (r)
Innings pitched: 54 (i)
Earned runs average: ? (ERA/E)
2. Replace your data in the formula.
Ei = 9r
E(54) = 9(25)
3. Solve the operations.
E(54) = 225
4. Now we use the transposing method to find E (ERA). 54 is
multiplying E, so it's going to move to the other side of the
equation dividing like this.
E(54) = 225 ⇒ E = 225/54
5. Calculate the result for E.
E = 4.1666666667
6. Finally, we round our answer.
E = 4.17
So, the earned runs average (ERA) is 4.17.

A recipe for banana bread requires 3 cups of bananas for every 1 1/2 cups of sugar used. At this rate, how many cups of sugar should be used if 2 cups of bananas are used
Answer:
4 cups of sugar will be added with 2 cups of banana in the banana recipe.
Step-by-step explanation:
A recipe for banana bread requires 3 cups of banana and [tex]1\frac{1}{2}[/tex] cups of sugar.
To calculate the cups of sugar used with 2 cups of bananas we will use unitary method.
∵ [tex]\frac{3}{2}[/tex] cups of sugar is used with amount of banana = 3 cups
∴ 1 cup of sugar will be used with banana = [tex]\frac{3}{\frac{3}{2}}[/tex]
∴ 2 cups of sugar will be used with banana = [tex]\frac{2\times 3}{\frac{3}{2} }[/tex] = [tex]6\times \frac{2}{3}[/tex]
= 4 cups
Therefore, 4 cups of sugar will be added with 2 cups of banana in the banana recipe.
