The length of a rectangle is 3 times the width.the permitted of the rectangle is 72ft find the dimensions of the rectangle

Answers

Answer 1
Lets set up the relationship of the length to width:

l = 3w

Using this, we can make all the variables the same by substitution:

2l + 2w = perimeter
2l + 2w = 72
2(3w) + 2w = 72
6w + 2w = 72
8w = 72
w = 9

The width is 9, to the length must be 9*3, or 27.

Your gross weekly salary is $800.00. Your federal income tax deduction is $53. The Social Security tax is 6.2%. The Medicare tax is 1.45% of gross pay. The state tax is 1.5% of gross pay. Each week you have $28.40 deducted for medical insurance and $12.00 for a health savings account. What is your net pay?

Answers

The net weekly pay is $633.4

How to determine the net pay?

The gross pay is given as:

Gross = $800.00

The deductions are:

Federal income tax deduction = $53.Social Security tax = 6.2%. Medicare tax = 1.45%State tax = 1.5%Medical insurance = $28.40Health savings account = $12.00

The net pay is then calculated as:

Net pay = 800.00 - (53 + 6.2% * 800 + 1.45% * 800 + 1.5% * 800 + 28.40 + 12.00)

Evaluate

Net pay = 633.4

Hence, the net weekly pay is $633.4

Step-by-step explanation:

Baker starts with [tex]\frac{4}{10}[/tex] kilograms of flour to make bread.

He further adds flour to his bread mixture = [tex]\frac{3}{100}[/tex] kg

Now we have to calculate the amount of flour he used to make the bread.

Total flour = [tex]\frac{4}{10}+\frac{3}{100}[/tex]

When you are comparing two sets of​ data, and one set is strongly skewed and the other is​ symmetric, which measures of the center and variation should you choose for the​ comparison?

Answers

Given that one set of data is symmetric while the other one is strongly skewed, the most appropriate measure of the center is median. Median is the value of the data which is at the center. This means that half of data are less than the median while half are greater than.

The variation can however be measured through the use of Quartiles method in order for our data to be equally divided into four equal group that allows us to determine how the data are spread out. 

When comparing two sets of data, choose the median for skewed data and mean with standard deviation for symmetric data.

When comparing two sets of data where one is strongly skewed and the other is symmetric, for the comparison, it is advisable to choose the median as the measure of the center for the skewed data since it is resistant to outliers, and the mean and standard deviation for the symmetric data to give an overall representation of the data.

The stage manager of a school play creates a rectangular acting area of 42 square yards. String lights will outline the acting area. To the nearest whole number, how many yards of string lights does the manager need to enclose this area?

Answers

Given that the stage manager of a school play creates a rectangular acting area of 42 square yards.

Let the length of the rectangular acting area be x, then the width is given by 42 / x.

The number of yards of string lights that the manager need to enclose the area is given by the perimeter of the rectangular area.

Recall that the perimeter of a rectangle is given by
P = 2(length + width) = 2(x + 42/x) = 2x + 84/x

The perimeter is minimum when the differenciation of 2x + 84/x is equal to 0.
i.e. [tex]2 - \frac{84}{x^2}=0\\ \\ \Rightarrow2x^2-84=0\\ \\ \Rightarrow x^2=42\\ \\ \Rightarrow x\approx6.48[/tex]

Therefore, the minimum number of yards of string lights the manager need to enclose this area is given by
[tex]2(6.48)+ \frac{84}{6.48} =12.96+12.96=25.92\approx26\ yards[/tex]

Point Q is the midpoint of GH. GQ=2x+3, and GH=5x−5 .

What is the length of GQ?

Enter your answer in the box.

____ units

Answers

Final answer:

The length of GQ is 25/3 units.

Explanation:

To find the length of GQ, we need to equate GQ to GH and solve for x. Since Q is the midpoint of GH, the lengths GQ and QH are equal. Therefore, we have the equation:

2x + 3 = 5x - 5

Subtract 2x from both sides:

3 = 3x - 5

Add 5 to both sides:

8 = 3x

Divide both sides by 3:

x = 8/3

To find the length of GQ, substitute the value of x back into 2x + 3:

GQ = 2(8/3) + 3

GQ = 16/3 + 3

GQ = 16/3 + 9/3

GQ = 25/3 units

Answer:

(2x + 1) - (–x² + 3x) is difference .

Step-by-step explanation:

Given : r(x) = –x² + 3x  and  s(x) = 2x + 1

To find : Find the difference of functions s and r .

Solution :  We have given that  r(x) = –x² + 3x and s(x) = 2x + 1.

Difference :

(s – r)(x) = s(x) - r(x)

              =(2x + 1) - (–x² + 3x)

              = 2x +1 + x²-3x

             = x²-x +1.

Therefore, (2x + 1) - (–x² + 3x) is difference .

The difference of the function is (2x+1)-(x^2 + 3x)

Difference of functions

Given the following functions

r(x) = –x² + 3x

s(x) = 2x + 1

Taking the difference of the function will give:

(s – r)(x) = 2x - 1 - (-x^2 + 3x)

Expand

(s – r)(x) = 2x - 1  + x^2 - 3x

(s – r)(x) = x^2 - x - 1

Hence the difference of the function is (2x+1)-(x^2 + 3x)

which shows the set(s) the number 2.77 is an element of?

Answers

real numbers
2.77 is not a natural number (counting numbers 1, 2, 3, ...)
2.77 is not a whole number (non-negative integers 0, 1, 2, 3, ...)
2,77 is not an element of null set as a null set has no elements.

{5, 7, 9}
The elements 5, 7 and 9 are elements of set D and they are also elements of set E.

The correct answer is option a. 2.77 is an element of the set real numbers.

To determine which set(s) the number 2.77 is an element of, let's analyze each option:

1. Real numbers: The set of real numbers includes all rational and irrational numbers. This means any number that can be placed on the number line, including integers, fractions, and decimals. Since 2.77 is a decimal number, it is indeed a real number.

2. Real numbers and natural numbers: While 2.77 is a real number, natural numbers are a subset of real numbers that consist of all positive integers (1, 2, 3, ...). Since 2.77 is not a positive integer, it is not a natural number. Therefore, this option is incorrect because 2.77 is not a natural number.

3. Natural numbers and whole numbers: As mentioned, natural numbers are positive integers. Whole numbers include all natural numbers and the number 0 (0, 1, 2, 3, ...). Since 2.77 is neither a natural number nor a whole number, this option is incorrect.

4. Null set: The null set (or empty set) contains no elements. If 2.77 were in the null set, it would imply that the null set is not empty, which contradicts the definition of the null set. Therefore, this option is incorrect.

m<A= x = 10

answer
m<A = 10

The measure of angle m∠A such that ∠A and ∠B are vertical angles is 10.

What is an angle?

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

Vertical angles are opposite angles become by the intersection of two straight lines and having the same measure.

Given that ∠A and ∠B are vertical angles

∠A = ∠B

x = 4x - 30

4x - x = 30

3x = 30

x = 10
