Answer:
perimeter of square=4×side
perimeter of square =4×13cm
perimeter of square = 52cm
area of square = side²
area of square = (13cm)²
area of square = 169cm²
Answer:
52 cm / 169 cm²
Step-by-step explanation:
To find the perimeter, we can add together the lengths of all the sides. Since the height and width of the square are the same length, we can tell all four sides are equal.
13 + 13 + 13 + 13 = 52
The perimeter is 52 cm.
The area is the length times the width of the shape, so we have to multiply 13 by 13.
13 · 13 = 169
The area is 169 cm².
The answer is the third option, 52 cm / 169 cm².
Good luck :)

12 +8 IS NOT greater than 20
4x +2x+2 +x+3 = 40
7x +5=40
7x =3 5
x=5
side 4x = 20
side x+3 = 8
side 2x+2 = 12
20 +8 is bigger than 12
20+12 is bigger than 8
12 + 8 IS NOT BIGGER than 20 (it's just the same)

What is the probability that a randomly selected subprime mortgage in the state during November 2008 was not current? (Round your answer to two decimal places.)
Answers
Complete question is;
The attached chart shows the (approximate) total number of subprime home mortgages in a state in November 2008, broken down into four categories.
What is the probability that a randomly selected subprime mortgage in the state during November 2008 was not current? (Round your answer to two decimal places.)
Answer:
Probability that the one randomly selected was not current = 0.36
Step-by-step explanation:
From the attached image, we can see that the four mortgage categories are mutually exclusive. This means that none of the 4 status depends on any other.
From the image attached;
Total number of subprime mortgages = 196,280
Number of current mortgages = 126,330
Thus;
Probability of a randomly selected subprime mortgage being current = 126330/196280 = 0.64
Then;
Probability that the one randomly selected was not current = 1 - 0.64
Probability that the one randomly selected was not current = 0.36

A company is going to make an oil container in the shape of a cylinder. As shown below, the container will have a height of 6m and a diameter of 6m. The container will be made from steel (including its top and bottom). If the steel costs $27 for each square meter, how much will the steel cost in total? If necessary, refer to the list of geometry formulas. For your calculations, do not round any intermediate steps, and use the π button on the ALEKS calculator. Round your answer to the nearest cent
Answers
Answer:
The cost of required steel is [tex]169.56 *27 = 4578.12[/tex] dollars
Step-by-step explanation:
The surface area of cylinder will be equivalent to the area of the steel sheet.
Surface area of cylinder [tex]= 2\pi rh+2\pi r^2[/tex]
Substituting the given values we get
Surface area of cylinder
[tex]= 2*3.14*3*6 + 2*3.14 *3^2\\= 169.56[/tex]square meter
Cost of 1 square meter of steel is $27
Then, the cost of required steel is
[tex]169.56 *27 = 4578.12[/tex] dollars

Total surface area of cone
Computation:
Total surface area of cone = πr[l + r]
Total surface area of cone = (22/7)(8)[15 + 8]
Total surface area of cone = (22/7)(8)[23]
Total surface area of cone = (22/7)(184)
Total surface area of cone = 4,048 / 7
Total surface area of cone = 578.28 unit²
