It can be proved that Circles X and Y are similar.
How can we prove that the circles are similar?We were told that circle Y have a radius of s
And X have the Radius r
Going with the theorem that Similar shapes are proportional, we can find the scale factor from circle X to circle Y by making a division on the radii of both circles.
Then the scale factor is [tex]\frac{s}{r}[/tex] which implies that circle Y will gotten by dilation of circle Y.
Therefore, both circles are similar

A rectangle has a width of x centimeters and a perimeter of 8x centimeters a square has sides of length 1/4 that of the length of the rectangle.
Find the perimeter of the square
The perimeter of the square is calculated to be (8 - x) cm
How to find the perimeter of the squareThe perimeter of a square is calculated using the formula
= 4 * length
From the problem we have that the length of the square
= 1/4 length of rectangle
perimeter of rectangle
8 = 2(Length + width)
dividing through by 2
4 = L + w
substituting w = x
8 = L + x
L = 8 - x
length of square = 1/4 * 8- x = (8 - x)/4
perimeter of a square = 4 * (8 - x)/4
perimeter of a square = 8 - x

What is the value of exponential 4?
The value of exponential 4 is 4^4, or 256. it means that 4 should be multiplied by itself 4 times.
In mathematics, an exponential is a number that is multiplied by itself a certain number of times. For example, when 4 is used as an exponential, it means that 4 should be multiplied by itself 4 times. This is written as 4^4, or 4 to the fourth power. This means that 4 is multiplied by itself 4 times, resulting in the value of 256.
Exponentials can be used to calculate the power of a number. For example, in the case of 4^4, 4 is the base number and 4 is the exponent. An exponent is the number of times a base number is multiplied by itself. In this case, the base number (4) is being multiplied by itself 4 times, resulting in a value of 256.
In addition, exponentials can be used to solve equations. For example, if we need to solve for x in the equation 4^x = 256, we can use the exponential 4 to determine the value of x. In this case, x = 4 because 4^4 = 256.

What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
John is driving around town. When he reaches the gas station, he notes that he has traveled 11 miles.
And, He reaches home 2 hours later and notes that he has traveled 30 miles.
Now, Let d represents the distance and t represents the time, in hours
So we get;
Let the equation which model this situation,
⇒ d = a t + b
Where a and b are constant.
Let the gas station is the starting point.
So, at gas station t = 0 , d = 11
Hence,
⇒ 11 = 0 × a + b
⇒ b = 11
When he reaches home 2 hours later notes that he has traveled 30 miles.
And, with substituting with b = 20
⇒ 30 = 2 × a + 11
⇒2a = 30 - 11 = 19
⇒ a = 19/2 = 9.5

Marhall and Vickie are alepeople who earned the ame amount thi week, although Vickie made 6 more ale than Marhall. Marhall earn a bae of $186 plu $15 per ale. Vickie earn a bae of $48 plu $18 per ale. How many ale did Marhall make thi week?
Marhall made 9 ales this week, earning a base of $186 plus $15 per ale. Vickie earned a base of $48 plus $18 per ale. Since both of them earned the same amount, we can set up the equations
Marhall made 9 ales this week.
Step by explanation
We can use an equation to solve this problem.
Let x = number of ales Marhall made
Marhall's Earnings = 186 + (15 x)
Vickie's Earnings = 48 + (18 x)
Since both of them earned the same amount, we can set up the equations and solve for x:
186 + (15 x) = 48 + (18 x)
15x = 138
x = 9
Therefore, Marhall made 9 ales this week.
Marhall made 9 ales this week, earning a base of $186 plus $15 per ale. Vickie earned a base of $48 plus $18 per ale.

For the questions that follow, suppose that the company is telling the truth. (a) Can you calculate the probability that a single randomly selected can contains 11.9 ounces or less? If so, do it. If not, explain why you cannot. (b) A quality control inspector measures the contents of an SRS of 50 cans of the company's soda and calculates the sample mean 7. Calculate the mean and standard deviation of the sampling distribution of x for samples of size n = 50. Interpret the standard deviation. (c) What is the shape of the distribution described in part (b)? Justify your answer. (d) The inspector in part (b) obtains a sample mean of x = 11.9 ounces. Calculate the probability that a random sample of 50 cans produces a sample mean amount of 11.9 ounces or less.
Previous question
a. We cannot calculate the probability, because we do not know the shape of the distribution.
b. The mean and standard deviation of the sampling distribution of x are 12 and 0.0566.
c. The shape of the distribution described in part b is symmetrical.
d. The probability that a random sample of 50 cans produces a sample mean amount of 11.9 ounces or less is 0.0386.
We do not know the shape of the distribution, so we cannot calculate the probability that a single randomly selected can contains 11.9 ounces or less. The question given have not told us that the distribution of individual cans was normal, and we cannot assume it is so; therefore, we cannot calculate its probability.
As given information the mean μx = 12.
And standard deviation σx = σ / √n = 0.4 / √50 = 0.566.
The shape of the distribution described in part b is symmetrical, because the two sides of the distribution are a mirror image of each other. Therefore, it is normal distribution.
Since the sample is large n = 50 and 50 > 30, so by CLT (Central Limit Theorem), the distribution of sample means is approximately normal N(12, 0.0566). So, P(x ≤ 11.9) = normalcdf (0, 11.9, 12, 0.0566) = 0.0386.

The total cost of a pair of sandals is given by the equation A = $ 18.39
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of pair of sandals be represented as A
Now , the equation will be
The total amount spent by Bonnie = $ 77.77
The cost of one shirt = $ 11.49
So , the cost of 2 shirts = 2 x 11.49 = $ 22.98
And , the cost of 1 pair = $ 32
The total tax on the purchase = $ 4.40
So , the cost of pair of sandals A = total amount spent by Bonnie - cost of 2 shirts - cost of 1 pair - total tax on the purchase
Substituting the values in the equation , we get
The cost of pair of sandals A = 77.77 - 22.98 - 32 - 4.40
On simplifying the equation , we get
The cost of pair of sandals A = $ 18.39
