What are the dimensions of the table runner
The length of the rectangle is 20 inches, and the width of the rectangle is 4 inches if the table runner has an area of 80 square inches. The length and width of the table runner are whole numbers. The length is 5 times greater than the width.
What is the area of the rectangle?It is defined as the space occupied by the rectangle which is planner 2-dimensional geometry.
The formula for finding the area of a rectangle is given by:
Area of rectangle = length × width
The area of the table runner = 80 square inches
Let's assume the length of the rectangle is L and the width is W
Then L = 5×W ...(1)
L×W = 80 ...(2)
Put the value of L in the equation (2)
5W(W) = 80
5W² = 80
W² = 16
W = ±4
Width cannot be negative.
W = 4 inches putting this value in the equation (1)
L = 5(4) = 20 inches
Thus, the length of the rectangle is 20 inches, and the width of the rectangle is 4 inches if the table runner has an area of 80 square inches. The length and width of the table runner are whole numbers. The length is 5 times greater than the width.

FIND THE SURFACE AREA OF THE CYLINDER
Answer: A≈1015.4
Step-by-step explanation:
A=2πrh+2πr2=2·π·8·12.2+2·π·82≈1015.36275
Answer:
407 mm²
Step-by-step explanation:
The formula for the surface area of a clyinder is: A = 2[tex]\pi[/tex]r · (r + h)
Plugging in the given values, we have: A = 2[tex]\pi[/tex]4 · (4 + 12.2)
A = 2[tex]\pi[/tex]4 · (4 + 12.2)
A = 2[tex]\pi[/tex]4 · 16.2
A = 2(3.14)4 · 16.2
A = 406.944
A = 407 (rounded)

"twice the sum of a number and three is eighteen"
Answer:
7.5
Step-by-step explanation:
how i figured it is 18-3 is 15
2*7 is 14 so in turn 7.5 *2 is 15 so
z=7.5
This can be represented in the form of an equation as: 2(x + 3) = 18.So, the correct Answer is A. 2(x+3)=18.
The correct translation of the given sentence is:" twice the sum of a number and three is eighteen".
The equation "2(x + 3) = 18" correctly represents the statement "twice the sum of a number and three is eighteen."

Given z1 = 5 – 2i and z2 = 3 + 2i, which letter represents z1 – z2?
[tex]z_1 - z_2 \\\\=(5-2i) -(3+2i)\\\\=5-2i-3-2i\\\\=2-4i[/tex]
Answer:
z1 - 2z = 2
Step-by-step explanation:
make 2i stand alone in both equations
therefore, in equation one, we have;
z1-5=-2i
5-z1=2i
we do same in equation 2
z2-3=2i
therefore, comparing the two equations, we can equate them!
2z-3=z1-5
-3+5=z1-2z
2 = z1 - 2z
therefore, z1 - 2z = 2

The circumference of a circle is 10π ft. What is the area, in square feet? Express your answer in terms of \piπ.
Answer:
A = 25π square feet
Step-by-step explanation:
C = 2πr
10π = 2πr
10π = 2πx
10π / 2π = 2πx / 2π
5 = x
This means 5 is the radius of the circle. We now need to find the area:
A = πr[tex]r^{2}[/tex]
A = π(5)²
A = π(25)
A = 25π

Approximately 30,300 citizens of a country died in an automobile accidents in 2015. Express this toll in deaths per day.
Answer:
144 deaths
Step-by-step explanation:
So, assuming it's not a leap year 30,300 must be divided by the number of days in the year to get the daily amount.
30,300/365 = 114.339....
since 3 is not greater than 5, the 144 does not round up but stays the same.
(Since you cannot have a fraction of a death)
114 is your answer

Giselle works as a carpenter and as a blacksmith.
She earns $20per hour as a carpenter and $25dollar sign per hour as a blacksmith. Last week, Giselle worked both jobs for a total of 30 hours, and earned a total of $690
How long did Giselle work as a carpenter last week, and how long did she work as a blacksmith?
Answer:
she worked 12 hours as a carpenter and 18 hours as a blacksmith
Step-by-step explanation:
Let x = the number of hours for which she worked as a carpenter
Let y = be the number of hours for which she worked as a blacksmith
Total numbers of hours she worked = 30
x + y = 30 (1)
she earned a total $690. She earned $20 dollar per hour as a carpenter and $25 per hour as a blacksmith.
20 x + 25 y = 690 (2)
Equation (2) - 20 × Equation (1),
We get,
5 y = 90 ⇒ y = 18
After substituting this value in equation (1),
We get, x = 12,
Hence, She worked as a carpenter = x hours = 12 hours
And, as a blacksmith = y hours = 18 hours

26,30,45,43,26,14,28,33,56,29,what is the mean absolute deviation of the data set
Answer: 9.
Step-by-step explanation: To find the MAD (mean absolute deviation) we need to do the following steps below:
1. Find the mean.
2. Subtract the mean from the numbers of the data.
3. Add the results and divide to find the MAD.
The steps are done below:
1. Find the mean: In order to find the mean of a data set, you need to add all the numbers and then divide the result by how many numbers there are in the data set. In this problem, there are 10 numbers in the data set, so whatever we get for adding the data numbers together needs to be divided by 10.
26 + 30 + 45 + 43 + 26 + 14 + 28 + 33 + 56 + 29 = 330.330 / 10 = 33.2. Subtract the mean from the numbers of the data: To do this, we need to subtract 33 from all the numbers on the data. The following is done below. (*Note: You may notice that most equations like 26 - 33 would be in the negatives, but for data, it has to be positive. If you ever run into a situation like that, you simply just make it positive).
26 - 33 = 7.30 - 33 = 3.45 - 33 = 12.43 - 33 = 10.26 - 33 = 7.14 - 33 = 19.28 - 33 = 5.33 - 33 = 0.56 - 33 = 23.29 - 33 = 4.3. Add the results and divide to find the MAD: Now that we have the results, we add those numbers and then divide to find the MAD. Make sure that when you divide that it is 10 that you're dividing because once again, there are 10 numbers for the results.
7 + 3 + 12 + 10 + 7 + 19 + 5 + 0 + 23 + 4 = 90.90 / 10 = 9.Therefore, 9 is the MAD.
