The thickness of a surfboard relates to the weight of the surfer. A surfboard is 21/3/16 inches wide and 2/3/8 inches thick. Write each dimension as a decimal.
Answer: Each dimension would be 21.1875 inches and 2.375 inches respectively.
Step-by-step explanation:
Since we have given that
Width of a surfboard = [tex]21\dfrac{3}{16}\ inches[/tex]
Thickness of a surfboard = [tex]2\dfrac{3}{8}\ inches[/tex]
We need to rewrite each dimension as a decimal.
We first write it in improper fraction:
Width becomes
[tex]21\dfrac{3}{16}\\\\=\dfrac{339}{16}\ inches[/tex]
Thickness becomes
[tex]2\dfrac{3}{8}\\\\=\dfrac{19}{8}\ inches[/tex]
Now, we change it into decimal form:
[tex]\dfrac{339}{16}=21.1875\ inches\\\\and\\\\\dfrac{19}{8}=2.375\ inches[/tex]
Hence, each dimension would be 21.1875 inches and 2.375 inches respectively.
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.

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.

Suppose that you have a stack of pennies. If you want to know without counting whether there is an odd or even number of pennies, then you have to split them into two parts, for example, placing one coin left and one coin right.
If the number of pennies is even, then no coins will left, if the number is odd, then one coin will be extra.

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
