what is it you don't understand about this ?
the question only asks about a wallpaper border, which is a strip.
so, we don't need any areas, we only need the perimeter of the room.
that means we need to add up all sides.
the little "missing corner" on the top right would hurt us for the area of the room, but not for the perimeter.
just imagine, the room would be a perfect rectangle.
how long would the top side be ?
right, identical to the bottom side : 8 ft.
and how long would the right side be ?
right, identical to the left side : 4 yds.
now, look closely, did we lose (or add anything) of/to the side lengths by the missing corner up there ?
we lost area, but ... we did not lose perimeter distance !
i know, this sounds funny, but it is true. look again.
the short right side plus the long right side are together still the same length as the left side : 4 yds.
and the long top side and the shorter lower top side together are still the same length as the bottom line : 8 ft.
attention trap : the left and right sides are in yds.
1 yd = 3 ft !
so, long story short, the perimeter is as for a normal rectangle
2×length + 2×width = 2×8 + 2×4×3 = 16 + 8×3 = 40 ft
and the border costs $3 per ft, so we get
3×40 = $120
as the total price for the border.

A square coffee table has an area of 150 square inches. What is the length of the coffee table? Round your answer to the nearest hundreth.
Answers
explanation: a square has 4 sides of equal length, meaning you divide 150 by 4 because thats how many sides there are.
Length of the coffee table will be 12.25 inch
What is Area of square?
The area of square is length time width.
Given that;
Area of square coffee table = 150 square inches.
Now,
Area of square = (side)²
Substitute the value of area of square,
Side² = 150
Take square root both sides,
Side = √150
Side = 12.247
After rounding it,
Side = 12.25
Thus, Length of the coffee table will be 12.25 inch.

Answer:
[tex]\dfrac{4}{7}x^7-\dfrac{1}{2}x^4+\dfrac{7}{2}x^2-4x+\text{C}[/tex]
Step-by-step explanation:
Integration is the "opposite" of differentiation.
Fundamental Theorem of Calculus
[tex]\displaystyle \int \text{f}(x)\:\text{d}x=\text{F}(x)+\text{C} \iff \text{f}(x)=\dfrac{\text{d}}{\text{d}x}(\text{F}(x))[/tex]
If differentiating takes you from one function to another, then integrating the second function will take you back to the first with a constant of integration (C).
[tex]\boxed{\begin{minipage}{5 cm}\underline{Integrating a constant}\\\\$\displaystyle \int n\:\text{d}x=nx+\text{C}$\\(where $n$ is any constant value)\end{minipage}}[/tex]
Just add an x to the constant.
[tex]\boxed{\begin{minipage}{4 cm}\underline{Integrating $x^n$}\\\\$\displaystyle \int x^n\:\text{d}x=\dfrac{x^{n+1}}{n+1}+\text{C}$\end{minipage}}[/tex]
Increase the power by 1, then divide by the new power.
[tex]\boxed{\begin{minipage}{5 cm}\underline{Terms multiplied by constants}\\\\$\displaystyle \int ax^n\:\text{d}x=a \int x^n \:\text{d}x$\end{minipage}}[/tex]
If the terms are multiplied by constants, take them outside the integral.
Given indefinite integral:
[tex]\displaystyle \int (4x^6-2x^3+7x-4)\:dx[/tex]
Integrate each term separately and take the constants outside the integrals:
[tex]\implies \displaystyle 4 \int x^6\:\text{d}x - 2 \int x^3 \:\text{d}x + 7 \int x \:\text{d}x - \int 4 \:\text{d}x[/tex]
Integrate, using the rules given above:
[tex]\implies 4 \cdot \dfrac{x^7}{7}-2 \cdot \dfrac{x^4}{4}+7 \cdot \dfrac{x^2}{2}-4x+\text{C}[/tex]
Simplify:
[tex]\implies \dfrac{4}{7}x^7-\dfrac{1}{2}x^4+\dfrac{7}{2}x^2-4x+\text{C}[/tex]
As one calculation:
[tex]\begin{aligned}\displaystyle \int (4x^6-2x^3+7x-4)\:dx & = \displaystyle 4 \int x^6\:\text{d}x - 2 \int x^3 \:\text{d}x + 7 \int x \:\text{d}x - \int 4 \:\text{d}x\\\\& = 4 \cdot \dfrac{x^7}{7}-2 \cdot \dfrac{x^4}{4}+7 \cdot \dfrac{x^2}{2}-4x+\text{C}\\\\& = \dfrac{4}{7}x^7-\dfrac{1}{2}x^4+\dfrac{7}{2}x^2-4x+\text{C}\end{aligned}[/tex]

What is the mean for Doctor A’s data set on corrective lenses? What is the mean for Doctor B’s data set on corrective lenses? Write a sentence comparing the number of people who wear corrective lenses in the two data sets.
Answers
Answer: Doctor A: 751.6 Doctor B: 755.2 Doctor B has an average of 3.6 more patients wearing corrective lenses than Doctor A.
Step-by-step explanation:
To find the mean for corrective lenses, add up all of the numbers and divide by the number of data points.
Doctor A's mean:
Add up the data points: 745+726+769+765+756+742+747+748+770+738 = 7516. Count the number of data points to get 10. Divide 7516 by 10. 7516/10 = 751.6.
Doctor B's mean:
Add up the data points: 763+736+735+759+748+756+765+761+768+761 = 7552. Divide by 10. 7552/10 = 755.2

755.2-751.6 = 3.6

A bag contains 9 pennies , 8 nickels, and 5 dimes. How many quarters should be added to the bag so the probability of drawing a dime is 1/6?
Answers
Answer:
A bag contains 9 pennies, 8 nickels and 5 dimes: 22 coins total
5/30 = 1/6
22 + 8 = 30
8 quarters would give the needed 30 coin total
P(dime) = 5/30 = 1/6
Step-by-step explanation:
No quarters should be added to the bag so the probability of drawing a dime is 1/6
Let x be the number of quarters to be added to the bag.
The probability of drawing a dime can be found by dividing the number of dimes in the bag by the total number of coins in the bag after adding x quarters.
The total number of coins in the bag before adding any quarters is:
9 pennies + 8 nickels + 5 dimes = 22 coins
After adding x quarters, the total number of coins in the bag becomes:
9 pennies + 8 nickels + 5 dimes + x quarters = 22 + x coins
The probability of drawing a dime is given as 1/6.
So, we can set up the equation:
5 / (22 + x) = 1/6
30 = 5(22 + x)
30 = 110 + 5x
-80 = 5x
x = -16
Since x represents the number of quarters to be added, it cannot be negative. Therefore, it is not possible to add any quarters to the bag so that the probability of drawing a dime is 1/6.
Hence, the answer is zero quarters.
