Answers
Formula
------------------------------------------------------------------------------
Perimeter = 2(Length + Width)
------------------------------------------------------------------------------
Perimeter of the Tennis Court
------------------------------------------------------------------------------
Perimeter of the Tennis Court = 2(Length + Width)
Perimeter of the Tennis Court = 2 (2x + 6 + x)
Perimeter of the Tennis Court = 2 (3x + 6)
Perimeter of the Tennis Court = 6x + 12
------------------------------------------------------------------------------
Perimeter of the Basketball Court
------------------------------------------------------------------------------
Perimeter of the Basketball Court = 2(Length + Width)
Perimeter of the Basketball Court = [tex]2(3x -14 + \dfrac{1}{2}x + 32)[/tex]
Perimeter of the Basketball Court = [tex]2( 3\dfrac{1}{2}x+ 18)[/tex]
Perimeter of the Basketball Court = [tex]7x + 36[/tex]
------------------------------------------------------------------------------
Answer: Tennis Court = 6x + 12 ; Basketball Court = 7x + 36
------------------------------------------------------------------------------
------------------------------------------------------------------------------
Difference in the two perimeter
------------------------------------------------------------------------------
(7x + 36) - (6x + 12)
= 7x + 36 - 6x - 12
= x + 24
------------------------------------------------------------------------------
Answer: Basketball Court is (x + 24) unit greater than Tennis Court
------------------------------------------------------------------------------
------------------------------------------------------------------------------
Tennis Court is 36 feet wide. Find dimension
------------------------------------------------------------------------------
Width of Tennis Court = x = 36 ft
Length of Tennis Court = 2x + 6 = 2(36) + 6 = 78 ft
Perimeter of Tennis Court = 6x + 12 = 6(36) + 12 = 228 ft
Width of Basketball Court = 1/2x + 32 = 1/2(36) + 32 = 50 ft
Length of Basketball Court = 3x - 14 = 3(36) - 14 = 94 ft
Perimeter of Basketball Court = 7x + 36 = 7(36) + 36 = 288 ft
------------------------------------------------------------------------------
Answer:
Tennis Court is 36 ft by78 ft and its perimeter is 228 ft.
Basketball Court is 50 ft by 94 ft and its perimeter is 288 ft

The ratio of the areas of two similar polygons can be found by using the ratio of their perimeters or the ratio of similarity and squaring it. Always Sometimes Never
Answers
The ratio of the areas of two similar polygons can be found by squaring the ratio of their perimeters or corresponding linear dimensions, but this method only works sometimes, specifically with similar polygons, and not with non-similar ones.
The ratio of the areas of two similar polygons is indeed found by taking the ratio of their corresponding linear dimensions and squaring it. This is because the area is a two-dimensional measurement, whereas perimeter and linear dimensions are one-dimensional. For similar polygons, which are polygons that have the same shape but may have different sizes, any linear dimensions (such as sides, perimeters, diagonals) are proportional.
When you have two similar polygons and you know the ratio of their perimeters, you can use this perimeter ratio to find the ratio of their corresponding side lengths since the ratio of the perimeters of similar polygons is equal to the ratio of their corresponding linear dimensions. After finding this linear ratio, you square it to obtain the ratio of their areas because if one dimension is multiplied by a scale factor 's', the area is multiplied by 's' squared (scale factor squared).
It is important to note, however, that this rule only applies to similar polygons (similarity) and not to polygons that aren't similar, since non-similar polygons do not have a constant ratio of corresponding linear dimensions. Therefore, to answer the original question, the method works sometimes, specifically when dealing with similar polygons.

Answers
132 〖in〗^2
Explanation
Although the diagram was not given, I was able to get it in the internet.
The area of a trapezium is found by the use of the following formula:
Area =1/2 h(a+b)
Where h is perpendicular distance between the two parallel lines, while a and b is are the lengths of the parallel lines.
In this question;
h=12 in
a=8 in
b=3+8+3=14 in
Area =1/2×12(8+14)
=6×22
132 〖in〗^2
Answer:
Option B. 132 inch²
Step-by-step explanation:
Since we know the formula to calculate the area of trapezoid is = [tex]\frac{1}{2}(height)(base)[/tex]
where height of the given trapezoid ABCD is side BE and two parallel sides are AB and DC.
It's given in the question
Side BE = 12 inches
AB = 8 inches
DC = (DF + FE + EC) = (3 + 8 + 3) = 14 inches
Now we put these values in the formula
Area of trapezoid ABCD = [tex]\frac{1}{2}(AB+CD).(BE) = \frac{1}{2}(8 + 14).(12)=\frac{1}{2}(22)(12)=(11).(12)=132[/tex]
Therefore answer is Option B. 132 inch²

Answers
When the data is skewed right or left, the pictorial representation of the data will show less data points on the side where it is skewed and more data on the opposite side. The tail will be longer on the right if it is skewed right and vice versa.
In data that is skewed right, the mean will be greater than the median and if the data is skewed left, the mean will be less than the median. Tje mean is not the measure of center when the data is skewed.

What is the greatest fraction you can make using the digits 4, 7, and 9?
Answers
Answer:
(7^9)/4 = 40,353,607/4
Step-by-step explanation:
Assuming each digit is used once and exponentiation is allowed, the largest numerator and smallest denominator will result in the largest fraction.
__
If other functions, such as factorial are allowed, then there might need to be a limit on the number of times they are applied. For example,
(7!)^(9!)/4 has about 1 million digits
something like ...
((7!)^(9!))!/4 has many more digits than that
and you can keep piling on the factorial symbols to any desired depth.

you have a piggy bank containing a total of 93 coins in dimes and quarters. If the piggy bank contains $14.85, how many dimes are there in piggy bank
Answers
Let q = number of quarters.
The total number of coins is 93, so the first equation is
d + q = 93
The value of 1 dime is $0.10. The value of 1 quarter is $0.25.
d dimes are worth 0.1d, and q quarters are worth 0.25q.
The total value of the coins is $14.85, so that gives us our second equation.
0.1d + 0.25q = 14.85
Now we have a system of two equations in two unknowns.
d + q = 93
0.1d + 0.25q = 14.85
Rewrite the first equation. Then multiply both sides of the second equation by -10, and write it underneath. Then add the equations.
d + q = 93
-d - 2.5q = -148.5
------------------------
-1.5q = -55.5
Divide both sides by -1.5.
q = 37
Now substitute 37 for q in the first original equation and solve for d.
d + q = 93
d + 37 = 93
Subtract 37 from both sides.
d = 56
Answer: There are 56 dimes in the piggy bank.

Draw three dimes 1 nickel and 2 pennies. Describe how to count on to find the total value of this group of coins
Answers
The total value of this group of coins can be found by first counting the value of each type of coin, and then adding them all together. The value of a dime is 10 cents, so if there are three dimes, the total value is 30 cents. The value of a nickel is 5 cents, so if there is one nickel, the total value is 5 cents. The value of a penny is 1 cent so if there are two pennies, the total value is 2 cents. After adding 30 + 5 + 2, the total comes to $0.37.

Mark wants a new car that costs $30,000. He only has $500 in his savings account and $300 in his checking account. Which financing option should he choose?
Answers
Answer:
Mark should lease the car with 0% down payment.
Step-by-step explanation:
We know that the new car will cost = $30000.
Mark has only (500+300) = $800 with him.
That means Mark has only 2.66% of the cost of the car which is very less amount.
Thus Mark should have the car by leasing it with 0% down payment because in this way he will be able to buy or own the car with out giving any money for the car or without actually paying for the car and he can also at the same time can have his entire savings amount that he has as savings account and checking accounts.
Thus, he should lease the car with 0% down payment.
