The length of a standard pickleball court is 4 feet more than twice the width. The total perimeter is 128 feet. What are the dimensions of a pickleball court?
Answer:
width= 20
length= 44
Step-by-step explanation:
we can say the width is x and the length is 2x+4 and there are 2 widths and two lengths. so 2x+4+2x+4+x+x=128, 6x+8 = 128 which means x=20 s0 the width is 20 and the length is 44
The length of the pickleball is 44 feet while the width is 20 feet.
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Perimeter of rectangle = 2( length + width).
Pickleball is a shape of a rectangle.
Let's say the length of the pickleball is L and the width is W
Given that,
The length of a standard pickleball court is 4 feet more than twice the width.
So,
L = 2W + 4
Perimeter 2(L + W) = 128
By substitution,
2(2W + 4 + W) = 128
3W + 4 = 64
W = 20
And L = 2(20) + 4 = 44
Hence "The length of the pickleball is 44 feet while the width is 20 feet".

proportional relationships
Answer:
relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other.
Step-by-step explanation:
If the standard volume of a
cube is 1.5cm³ calculate the
cm
percentage error in measuring its
volume which is found to be 1.6cm³
A:6.7%
B:-6.7%
C:5%
D:-5%
E:4%
Answer:
6.7 %
which agrees with answer A in your list.
Step-by-step explanation:
If the standard volume is 1.5 cubic cm, and the measured volume is 1.6 cubic cm, then the difference between these two is :
1.6 - 1.5 = 0.1 cubic cm. and therefore the percentage error is given by:
0.1/1.5 = 0.066666...which corresponds to a rounding of 6.7%
Recall as well that percent error is always expressed as a positive number.
What is the slope of the line that passes through the points (-2,8) and (-22,8)? Write your answer in simplest from
Answer:
[tex]\boxed{\tt m=0}[/tex]
Step-by-step explanation:
The slope formula is:
[tex]m=\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]
where (x₁, y₁) and (x₂,y₂) are the points on the line.
The points given are (-2,8) and (-22,8). Therefore,
[tex]x_{1}=-2\\y_{1}=8\\x_2=-22\\y_2=8[/tex]
Substitute the values into the formula.
[tex]m=\frac{8-8}{-22--2}[/tex]
Solve the numerator. Subtract 8 from 8.
[tex]m=\frac{0}{-22+2}[/tex]
Zero divided by any number is zero, so we automatically know the slope is zero.
[tex]m=0[/tex]
The slope of the line is 0
Answer: 0
Step-by-step explanation:
To find the slope, you need to use the formula [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. You use the given points to plug in and solve.
[tex]m=\frac{8-8}{-22-(-2)} =\frac{0}{-20}=0[/tex]
Now, we know that the slope is 0 meaning this is a horizontal line.
L is the midpoint of KM. If KL = 14x and KM = 26x + 14, what is KL? Simplify your answer and write it as a proper fraction, mixed number, or integer. Please type the answer step by step.
Answer:
Step-by-step explanation:
L is the midpoint of KM. So, length of KL = length of LM
KL = LM = 14x
KL + LM = KM
14x + 14x = 26x + 14 {add the like terms}
28x = 26x + 14 {subtract 26x form both sides}
28x - 26x = 14
2x = 14 {divide both side by 2}
2x/2 = 14/2
x = 7
KL = 14x = 14*7
KL = 98

Use rounding to estimate the product of 198 and 42 . Round both numbers to the nearest ten to find your answer.
Answer:
8000
Step-by-step explanation:
198 and 42 rounded to the nearest hundreths are 200 and 40. the product of 200 and 40 is 8000
The product of 198 and 42 rounded both numbers to the nearest ten
is 8000.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps its value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, Use rounding to estimate the product of 198 and 42.
Now, 198 rounded to the nearest ten is 200, and 42 rounded to the nearest ten is 40.
Therefore, The multiplication of 198 and 42 rounded to the nearest 10 is,
= 200×40.
= 8000.

Answer:
3^12 = 531441
Step-by-step explanation:
For this problem, it's important to understand what is meant by the exponents. Notice, there are two sets of separators, a parentheses and a bracket. When you have powers to powers you multiply, hence 2 * 3 * 2 is 12. The given expression can also be broken down like this:
[ ( 3^2 ) ^ 3 ] ^ 2
= [ 3^2 * 3^2 * 3^2 ] ^ 2
= 3^2 * 3^2 * 3^2 * 3^2 * 3^2 * 3^2
And we can apply the rule, when you are multiply powers of like bases you add the exponents. Hence:
3 ^ (2 + 2 + 2 + 2 + 2 + 2)
= 3^12
Either way of power manipulation, you end with the same result of 3^12. Hope this helps.

For a certain city, the temperature each day this week can be described by the inequality below.
3d +6<A
In the inequality, d is the daily temperature in degrees Fahrenheit and A is the average temperature for the year. If A = 54 °F, which statement BEST interprets the solution to the in
A The temperature each day this week was less than 90 "F
B The average temperature for the year was less than 90 °F
c The temperature each day this week was less than 72 °F
DO The average temperature for the year was less than 72 °F
Answer:
Option C.
Step-by-step explanation:
We have the following inequality :
[tex]3d+6<A[/tex] (I)
In which :
[tex]d[/tex] : '' The daily temperature in degrees Fahrenheit ''
[tex]A[/tex] : '' The average temperature for the year ''
We first need to find the solution (the inequality related to the value of [tex]d[/tex]) given that we set [tex]A=54[/tex] °F ⇒
Using the equation (I) :
[tex]3d+6<54\\3d<48\\d<16[/tex]
We find that the ''[tex]d[/tex]'' variable (daily temperature in degrees Fahrenheit) is less than [tex]16[/tex] °F.
The option B and the option D give us an interpretation about the [tex]''A''[/tex] variable.
Only the options A and C give us an interpretion about the [tex]''d''[/tex] variable
Between A and C, the option C is a more accurate option (because 72°F is closer to 16°F).
We answer that the option C best interprets the solution.
