As per the perimeter, the length of the rectangular floor is 72 meters, and the breadth is 36 meters.
Now we can use the formula for the perimeter of a rectangle to write an equation in terms of x and solve for x.
Perimeter of the rectangle = 2(length + breadth)
Given that the perimeter is 216 m, we can substitute the values of length and breadth in terms of x to get:
216 = 2(2x + x)
Simplifying this equation, we get:
216 = 2(3x)
Dividing both sides by 2, we get:
108 = 3x
Solving for x, we get:
x = 36
Now that we have the value of x, we can use it to find the length and breadth of the rectangular floor.
Length = 2x = 2(36) = 72 m
Breadth = x = 36 m

The owner of a beverage company wants to determine whether two of his machines are filling bottles with the correct amount of liquid. He randomly selects 20 bottles filled by each of the two machines and measures the number of ounces that the bottles contain. The histograms below show the data. If the machines are designed to dispense between 5 and 6 ounces into a bottle, which machine appears to be doing a better job? Explain how you determined your answer.
Based on the histograms, it appears that Machine B is doing a better job of dispensing the correct amount of liquid.
What is histogram?The most common graph for displaying frequency distributions is a histogram.
To begin, Machine B's histogram is more symmetrically distributed around the 5.5-ounce mark, which is the target fill level.
Machine A's histogram, on the other hand, is skewed to the right, indicating that it is more likely to dispense more than 5.5 ounces.
Second, Machine B's histogram has a narrower spread, with most measurements falling between 5.4 and 5.6 ounces.
This indicates that the machine fills the bottles consistently within a narrow range of the target fill level.
Thus, the histogram for Machine A, on the other hand, has a wider range, with some measurements falling below 5.4 ounces and others exceeding 5.6 ounces, indicating a less consistent performance.

∟A= 7x + 24° , ∟B = 3x + 92° Solve for x and then find the measure of ∟A:
∟A=_____°
Measure of ∟A is 119°
To solve for x, we must use the fact that the angles have the same measure, so ∟A = ∟B.
Substitute 7x + 24° for ∟A and 3x + 92° for ∟B and set them equal to each other:
7x + 24° = 3x + 92°
Subtract 3x from both sides:
7x - 3x = 92° - 24°
4x = 68°
Divide both sides by 4 to solve for x:
x = 17°
Now that we have x, we can substitute 17° for x into the original equation for ∟A to find its measure:
∟A = 7x + 24°
∟A = 7(17°) + 24°
∟A = 119°
Therefore, the measure of ∟A is 119°.

What is the intersection of the sets A = {2, 5, 6, 14, 16} and B = {1, 3, 6, 8, 14-37
The intersection set, A∩ B, of the sets A = {2, 5, 6, 14, 16} and B = {1, 3, 6, 8, 14 } is equals to the { 6, 14}.
For any two sets A and B, the intersection, A∩ B (read as A intersection B) lists all the elements that are present in both sets, and are the common elements of A and B. The intersection of sets is denoted by the symbol '∩'. It is subset of both of sets, A and B. For example, if Set A = {1,2,3,4,5} and Set B
= {3,4,6,8}, A ∩ B = {3,4}.
Here, we have two sets A = {2, 5, 6, 14, 16} and B = {1, 3, 6, 8, 14 }
The common elements in sets A and B

The average length of an official chess table in the International Chess Federation is 110 centimeters (cm)
with a tolerance of 16.5 cm. If c is the length of the chess table and V is the variation from 110 cm, the
function V(c) = |c-110| can be used to find the amount of variation.
Complete the statements by typing decimal values in the blank spaces.
Answer:
1. What is the maximum length of a chess table that is still within the tolerance limit?
To find the maximum length of a chess table that is still within the tolerance limit, we add the tolerance to the average length:
110 cm + 16.5 cm = 126.5 cm
Therefore, the maximum length of a chess table that is still within the tolerance limit is 126.5 cm.
2. What is the minimum length of a chess table that is still within the tolerance limit?
To find the minimum length of a chess table that is still within the tolerance limit, we subtract the tolerance from the average length:
110 cm - 16.5 cm = 93.5 cm
Therefore, the minimum length of a chess table that is still within the tolerance limit is 93.5 cm.

Ms.lang borrows $2,300 for 30 months at 13% interest per year. How much interest will ms.lang pay? What is the total amount she will repay?
Answer:
The formula to calculate simple interest is:
I = Prt
Where I is the interest, P is the principal amount borrowed, r is the interest rate per period, and t is the time period.
Using this formula, we can calculate the interest Ms. Lang will pay as follows:
I = Prt
I = 2300 * 0.13 * (30/12)
I = $975
Therefore, Ms. Lang will pay $975 in interest over the 30-month period.
To calculate the total amount she will repay, we need to add the interest to the principal amount borrowed:
Total amount = Principal + Interest
Total amount = $2300 + $975
Total amount = $3275
Therefore, Ms. Lang will repay a total of $3275, which includes the $2300 principal and $975 interest.
now, we're assuming this is on a simple interest rate, so hmm say a year has 12 months, so 30 months will just be 30/12 of a year.

The cargo bed of a commercial truck is shaped like a rectangular prism. The dimensions are shown. Billy has 80 cubic meters of mulch to take to his house. How many trips will he have to make until all the mulch is at his house?
Answer:
We need to find out how many trips Billy needs to make to transport 80 cubic meters of mulch. Since we know the dimensions of the cargo bed, we can find its volume and then divide the total volume of mulch by the volume of the cargo bed to find the number of trips.
The volume of the cargo bed is:
V = l × w × h
where l is the length, w is the width, and h is the height. Using the dimensions given in the diagram, we get:
V = 4 m × 2.5 m × 1.5 m = 15 cubic meters
Now we can divide the total volume of mulch by the volume of the cargo bed to find the number of trips:
Number of trips = total volume of mulch / volume of cargo bed
Number of trips = 80 cubic meters / 15 cubic meters ≈ 5.33
Since Billy cannot make a fractional number of trips, he will need to make 6 trips to transport all the mulch to his house.

Martina can run 4,920 more feet this year compared to last year.
Martina can run 3 miles without stopping. Last year she could run 3,640 yards without stopping. We need to find out how many more feet Martina can run this year compared to last year.
First, we need to convert both measurements to the same unit so that we can compare them. We will convert both measurements to feet.
1 mile = 5,280 feet
1 yard = 3 feet
So, 3 miles = 3 x 5,280 feet = 15,840 feet
And, 3,640 yards = 3,640 x 3 feet = 10,920 feet
Now, we can subtract the number of feet Martina could run last year from the number of feet she can run this year to find out how many more feet she can run this year.
15,840 feet - 10,920 feet = 4,920 feet
Therefore, Martina can run 4,920 more feet this year compared to last year.

what is the rule multiplying with different signs
Answer:
When you multiply two numbers with different signs (positive and negative), the result is always negative.
This can be understood in terms of the basic properties of multiplication and the fact that a negative number is essentially the opposite of a positive number. When you multiply a positive number by a positive number, the result is positive because both numbers are pointing in the same direction along the number line. When you multiply a negative number by a negative number, the result is also positive because both numbers are pointing in the opposite direction along the number line, and multiplying them together "flips" them back to the positive side. However, when you multiply a positive number by a negative number, the two numbers are pointing in opposite directions along the number line, and so their product is negative.
Therefore, the rule for multiplying two numbers with different signs is that the product is always negative.

a. What is the sum of their times?
b. What property or properties did you use?
c. Evaluate the expression if Doug ran the race in 27 minutes.
a) The sum of their times is of 4x + 3.
b) The property used is the combination of like terms, which we use to add the terms with the variable x.
c) If Doug ran the race in 27 minutes, the total time for the team is of 111 minutes.
How to obtain the expression?Doug finished first, and the times of the other two athletes are as function of Doug, hence the variable x represents the time needed for Doug to finish the race, that is:
D = x.
Kim finished 3 minutes after Doug, hence:
K = D + 3
K = x + 3.
Conner finished with a time that was twice Doug’s time, hence:
C = 2x.
Then the total time is given as follows:
T = D + K + C
T = x + x + 3 + 2x
T = 4x + 3.
If Doug ran the race in 27 minutes, the total time for the team is obtained as follows:
T = 4 x 27 + 3
T = 111 minutes.

The hypotenuse is sqrt(11^2 + 7^2) = sqrt(170). Then, sin t = 11/sqrt(170), cos t = 7/sqrt(170), csc t = sqrt(170)/11, sec t = sqrt(170)/7, and cot t = 7/11.
Since we know that tan t = 11/7, we can use the Pythagorean identity (sin^2 t + cos^2 t = 1) to find the other trigonometric functions. First, we will find sin t and cos t:
tan t = 11/7 = opposite/adjacent = sin t/cos t
sin t = 11*cos t
cos t = 7*sin t
Substituting the second equation into the first equation:
sin t = 11*(7*sin t)
sin^2 t = 121*sin^2 t
121*sin^2 t - sin^2 t = 0
120*sin^2 t = 0
sin^2 t = 0/120
sin^2 t = 0
sin t = 0
Since sin t = 0, cos t = 1. Now we can find the other trigonometric functions:
csc t = 1/sin t = 1/0 = undefined
sec t = 1/cos t = 1/1 = 1
cot t = 1/tan t = 1/(11/7) = 7/11
So, the values of the trigonometric functions are:
sin t = 0
cos t = 1
csc t = undefined
sec t = 1
cot t = 7/11

How do equations operate?Mathematical formulas frequently use the same variable letter to try to impose unity between two assertions. Many academic numbers are shown to be equal using mathematical equations, also known as assertions. Using y + 6 as an illustration, the normalise does not divide 12 into two parts, but instead b + 6. It is possible to determine the connection integer between each sign part and the number of lines. The significance of a symbol usually contradicts itself.
Here,
The following equation can be set up to represent the circumstance if x is the procedure's cost:
=> 5% of x = $4.80
The percentage must first be divided by 100 to become a decimal before we can answer for x:
=> 0.05x = $4.80
Then, by dividing both lines by 0.05, we can separate out x:
=> x = $96
Consequently, the process will cost you $96. It is possible to confirm that the gratuity is 5% of $96:
=> 5% of $96 = 0.05 × $96 = $4.80

A blue print of a house has a scale of 1. 5 in 5 feet would a ping pong table that is 9 feet by 5 feet fit in a space that has a drawing dimensions of 3 inches and 4. 8 inches if so how much space in feet square will remain after the table is put in the room
There will be about 111.25 square feet of space remaining in the room after the ping pong table is put in.
First, we need to convert the scale of the blueprint to a real-world scale. Since the scale is 1.5 in 5 feet, we can write this as:
1.5 inches : 5 feet
To convert this to a ratio that we can use, we can divide both sides by 1.5 inches:
1 inch : 3.33 feet
Now we can use this ratio to convert the dimensions of the room from the blueprint to real-world dimensions:
3 inches x 3.33 feet/inch = 9.99 feet
4.8 inches x 3.33 feet/inch = 15.96 feet
So the room is approximately 10 feet by 16 feet.
Next, we need to see if the ping pong table will fit in the room. The table is 9 feet by 5 feet, which means it needs at least a space of 9 feet x 5 feet = 45 square feet. To convert this to the scale of the blueprint, we can use the inverse of the ratio we calculated earlier:
1 foot : 1/3.33 inches
So the table needs at least a space of 9 feet x (1/3.33 inches/foot) = 27 inches by 5 feet x (1/3.33 inches/foot) = 15 inches on the blueprint.
The space in the room is 3 inches x 4.8 inches on the blueprint, which is equivalent to 3 inches x (1/1.5 inches/foot) = 2 feet and 4.8 inches x (1/1.5 inches/foot) = 1 foot 7.8 inches in real-world dimensions.
Since the table will fit on the blueprint, we can now calculate the remaining space in the room. The total area of the room is approximately 10 feet x 16 feet = 160 square feet.
The area taken up by the ping pong table is approximately 9 feet x 5 feet = 45 square feet, or 27 inches x 15 inches on the blueprint. To convert this to square feet, we can use the ratio we calculated earlier:
27 inches x (1/12 feet/inch) x 15 inches x (1/12 feet/inch) = 3.75 square feet
So the remaining space in the room is approximately 160 square feet - 45 square feet = 115 square feet - 3.75 square feet
= 111.25 square feet.
