Final answer:
To find the area of a circle with a circumference of 53.41 inches, calculate the radius using r = C / (2π) and then find the area using A = πr². The area is approximately 226.795 square inches.
Explanation:
To find the area of a circle given its circumference, you can use the formula for the circumference, C = 2πr, where C is the circumference and r is the radius. From there, you can derive the radius and then calculate the area using the formula A = πr². Given that the circumference is 53.41 inches, we first find the radius (r).
The formula for circumference (C) simplifies to r = C / (2π). Thus, r = 53.41 inches / (2×3.14), which gives us r = 53.41 / 6.28 = approximately 8.5 inches. Now that we have the radius, we can plug it into the area formula A = πr². Using the given radius, the area A equals 3.14×8.5² inches², which is about 3.14×72.25 inches² = 226.795 inches² (rounded to three significant figures).

100%-15%=85% -- 0.85
A. doesn't work because it is increasing
B. works because your finding 85 percent since you decrease by 15 percent
C. doesn't work because you are not taking 15 percent from value of t
D. doesn't work because finging 15 percent of t and them subtracting from one won't give you the right answer
E.doesnt work because all you have to do is find 85 percent not subtract that from the original value
F.works because subtracting 15 percent from one and multiply by t would give the equation from B

The sum of a number, n, and 8 is multiplied by -4, and the result is 12. What is the number?
Answer: -11
Step-by-step explanation:
(n+8)* -4= 12
-8 -8
n* -4= 12
/-4 /-4
n= -11
Based on the calculations, the unknown number (n) is equal to -11.
How to find an unknown number?In this exercise, you're required to find an unknown number (n). Thus, we would translate the word problem into an algebraic expression as follows:
The sum of a number (n) and 8:
n + 8
Multiplying by -4, we have:
(n + 8) × -4 = 12
-4n - 32 = 12
-4n = 12 + 32
-4n = 44
n = -11.

A. Y
B. Z
C. W
D. X
The possible outcomes of tossing a coin 4 times with 2 or 3 heads can be represented using a tree diagram.
Explanation:The possible outcomes of tossing a coin 4 times can be represented using a tree diagram. Each toss has 2 possible outcomes, either a head (H) or a tail (T). Starting with the first toss, there are 2 branches representing each possible outcome. For the second toss, each branch splits into 2 more branches representing the possible outcomes of the second toss, and so on. To find the outcomes with 2 or 3 heads, we need to count the paths on the tree diagram where there are 2 or 3 branches labeled as heads (H).
Let's label the paths as follows:
Y: HHTT
Z: HTHT
W: HTTH
X: TTHH
These are the possible outcomes with 2 or 3 heads. Therefore, the answer is option B. Z.

a soup can is in the shape of a cylinder with a radius of 1 inch and a height of 3 inches. how much paper is used for the label of the soup can, which covers the lateral surface surface area of the soup can
Answer:
18π in²
Step-by-step explanation:
We need to find the circumference of the edge of the cylinder. The formula for circumference is C = 2πr, where r is the radius.
Here, the circumference is 2π(3 in) = 6π in.
To find the surface area covered by the label, multiply this circumference by the can height, 3 in:
V = (6π in)(3 in) = 18π in²
Approximately 18.85 square inches of paper is used for the label that covers the Lateral surface area of the soup can.
Let's find the amount of paper used for the label that covers the lateral (side) surface area of the soup can, you can calculate the lateral surface area of the cylinder.
The formula for the lateral surface area of a cylinder is:
Lateral Surface Area = 2πrh
Where:
π (pi) is approximately 3.14159
r is the radius of the cylinder
h is the height of the cylinder
In this case, the radius (r) of the soup can is 1 inch, and the height (h) is 3 inches. Plug these values into the formula:
Lateral Surface Area = 2π(1 inch)(3 inches)
Lateral Surface Area = 2π(3 square inches)
Lateral Surface Area = 6π square inches
Now, you can calculate the approximate value:
Lateral Surface Area ≈ [tex]6 \times 3.14159[/tex] square inches
Lateral Surface Area ≈ 18.84954 square inches

All of the points are in the right places! :P
Answer:
All four points are in the right place.
Step-by-step explanation:
Here's what you need to check.
The coordinate of each point is a set of two number in a round bracket.
The first number is the x-coordinate of that point. That's the place of the point on the x-axis.The second number is the y-coordinate of that point. That's the place of the point on the y-axis.Taking point A (9, 7) as an example.
x-coordinate of A: 9.y-coordinate of A: 7.The x-axis is the horizontal axis. Find the tick with number "9" on the horizontal x-axis. Draw a vertical line through that tick. The x-coordinate of all points on that vertical line is 9. The y-axis is the vertical axis. Find the tick with number "7" on the vertical y-axis. Draw a horizontal line through that tick. The y-coordinate of all points on that horizontal line is 7.The two lines should intersect at some point on the grid. The x-coordinate of the place where they intersect is 9, and the y-coordinate will be 7. The intersect is the position of point A.Repeat these steps for the rest of the four points. See if every single point is in their place.
what is the sum? x/x+3 + 3/x+3 + 2/x+3
Answer: [tex]\frac{x+5}{x+3}[/tex]
Step-by-step explanation:
The problem gives you the following expression:
[tex]\frac{x}{x+3}+\frac{3}{x+3}+\frac{2}{x+3}[/tex]
Therefore, to add the fractions with equal denominator, you must rewrite the denominator (x+3) and add the numerators of each one of the fractions.
Then, keeping the above on mind, you obtain the sum shown below (You must remember to add the like terms):
[tex]\frac{x+3+2}{x+3}=\frac{x+5}{x+3}[/tex]
Answer:
The correct answer is (x + 5)/(x + 3)
Step-by-step explanation:
It is given an expression,
x/x+3 + 3/x+3 + 2/x+3
From the above expression we can see that, sum of three fractions
To find the sum
The above expression is sum of three fraction. The denominators are same which is (x + 3)
So we can add numerators
x/x+3 + 3/x+3 + 2/x+3 = ( x + 3 + 2)/(x + 3) = (x + 5)/(x + 3)
Therefore the correct answer is (x + 5)/(x + 3)

Answer:
C
Step-by-step explanation:
Since it is greater than or equal to, the graph line is a solid line.
Then, since we know that it is greater than, we know that we can shade above the graph line.
To check this, all you have to do is choose a random point in the shaded region and plug it in the equation. If it checks out, it is correct.
Answer:
Graph represented by option C is the correct choice.
Step-by-step explanation:
We are asked to graph an inequality [tex]y\geq2x-3[/tex].
The boundary line of our given inequality will be a solid line as we have greater than or equal to [tex]\geq[/tex] sign.
The boundary line of our given inequality would be [tex]y=2x-3[/tex].
Now, we will test point (0,0) to shade in the correct region as:
[tex]0\geq2(0)-3[/tex]
[tex]0\geq0-3[/tex]
[tex]0\geq-3[/tex]
Since the point (0,0) is a solution for our given inequality, therefore, the shaded area of our inequality will include point (0,0).

The cost, in dollars, of a single-story home can be approximated using the formula C- kiw, where i is the approximate length of the home and w is the approximate width of the home. Find the units for the coefficient k.
Its dollar per square foot
The unit for the coefficient 'k' in the equation 'C= kiw', given that 'C' is the cost in dollars and 'i' and 'w' are the dimensions of the home in an area-unit such as feet or meters, should be dollars per square foot or dollars per square meter.
Explanation:The question is asking to find the unit for the coefficient k in the equation 'C= kiw' where 'C' represents the cost of a single-story home, 'i' is the length of the home, and 'w' is the width of the home. In this equation, the cost 'C' is in dollars, and the length 'i' and width 'w' are likely in feet or meters (units of length).
Therefore, the coefficient 'k' must have the units that make the equation dimensionally consistent. In other words, the units of 'k' must be such that when multiplied by area ('iw' is an area), the result is cost. So, the unit for 'k' in this context would be dollars per square foot or dollars per square meter, depending on the units used for 'i' and 'w'.
