The triangles are similar. Find the value of x.
Since the triangles are similar, the value of x is equal to: C. 18 units.
What are the properties of similar triangles?In Mathematics, two (2) triangles are said to be similar when the ratio of their corresponding side lengths are equal and their corresponding angles are congruent.
By applying the properties of similar triangles, we have the following ratio of corresponding side lengths;
AC/RS = AB/RT
By substituting the given side lengths into the above equation, we have the following:
x/24 = 24/32
By cross-multiplying, we have the following;
32x = 24(24)
32x = 576
x = 576/32
x = 18 units.

Out of 80 customers at an ice cream van, 48 had syrup, 28 had sprinkles and 16 had both
toppings on their ice cream. Use a Venn diagram to find the probability that a randomly
selected customer doesn't have either topping, given that they don't have sprinkles.
I know the answer is 20/52, I just can’t work out how to get to that answer…
Answer:
20/52 or simplified to 5/13
Step-by-step explanation:
The Venn Diagram is provided
Let
n(A) = number of customers who had syrup
n(B) = number of customers who had sprinkles
n(A and B) = number of customers who had both syrup and sprinkles = 16
This would be the number in the overlapping region
n(A or B) = number of customers who had either syrup or sprinkles or both
= n(A) + n(B) - n(A and B)
= 48 + 28 - 16
= 60
Therefore number of customers who had neither topping = 80 - 60 = 20
This number is indicated outside both circles but within the rectangle
The number of customers who had only syrup is given by set difference
= No. of customers who had syrup - No. of customers who had both
= n(A) - n(A and B)
= 48 - 16
= 32
This is the figure inside the left circle
Let's consider the statement: Customers who didn't have sprinkles
This would be customers who had only syrup(32) + customers who had neither topping(20)
= 32 + 20 = 52
Number of customers who did not have either topping = 20
P(selected customer doesn't have either topping, given that they don't have sprinkles)
= 20/52
= 5/13

suppose there is $600 in the account with an annual interest rate of 4%. after how many years will the amount triple?
it will take approximately 22.56 years for the amount to triple.
The given information for this problem is that there is an initial investment of $600 in an account with an annual interest rate of 4%. The task is to determine after how many years the amount will triple.Using the compound interest formula, we can find the amount in the account after t years:A = P(1 + r/n)nt Where,A = final amount in the account, P = initial amount in the account r = annual interest rate ,n = number of times the interest is compounded per year ,t = time in years.
From the problem statement, we know that the initial amount, P, is $600 and the annual interest rate, r, is 4%. Let's assume that the interest is compounded annually, i.e., n = 1.Substituting these values in the formula, we get:A = $600(1 + 0.04/1)1t Simplifying this expression,A = $600(1.04)t.
Taking the ratio of the final amount to the initial amount, we get: 3P = $600 × 3 = $1800. Therefore,A/P = 3 = (1.04)t.Dividing both sides by P, we get:3 = (1.04)t ln(3) = ln(1.04)t. Using the logarithmic property, we can bring down the exponent to the front:ln(3) / ln(1.04) = t Using a calculator, we get ≈ 22.56. Therefore, it will take approximately 22.56 years for the amount to triple.

a box contains 8 red balls and 8 blue balls, and 4 balls are taken at random without replacement. what is the probability that 2 red balls and 2 blue balls are taken?
The probability that 2 red balls and 2 blue balls are taken from the box is 3/7. This can be expressed mathematically as [tex](8C2 * 8C2) / (16C4) = 3/7[/tex].
To better understand this probability, let's look at an example. Say there are 8 red balls and 8 blue balls in the box. This can be represented as:
R = 8, B = 8
We want to determine the probability of taking 2 red balls and 2 blue balls out of the box. To do this, we need to calculate the total number of ways of selecting 4 balls from the box (16 balls in total) and then calculate the total number of ways of selecting 2 red and 2 blue balls out of the box.
The total number of ways of selecting 4 balls from the box can be expressed as (16C4). This is calculated by dividing the number of ways of selecting 4 balls out of 16 (16!) by the number of ways of arranging those 4 balls in any order (4!):
[tex](16C4) = 16! / 4! = 1820[/tex]
The total number of ways of selecting 2 red and 2 blue balls out of the box can be expressed as (8C2 * 8C2). This is calculated by multiplying the number of ways of selecting 2 red balls out of 8 (8C2) by the number of ways of selecting 2 blue balls out of 8 (8C2):
[tex](8C2 * 8C2) = 8C2 * 8C2 = 28[/tex]
The probability of taking 2 red balls and 2 blue balls out of the box is then the ratio of the number of ways of selecting 2 red and 2 blue balls out of the box (28) to the total number of ways of selecting 4 balls from the box (1820):
P(2 red balls, 2 blue balls) = 28 / 1820 = 3/7
In conclusion, the probability of taking 2 red balls and 2 blue balls out of a box containing 8 red balls and 8 blue balls is 3/7.

If g(x) = 1 – 2x + 3x2, find the average rate of change of the function as x varies from 2 to 5
The average rate of change of the function as x varies from 2 to 5 is 22.
Given function: g(x) = 1 – 2x + [tex]3x^2[/tex]
To find the average rate of change of the function as x varies from 2 to 5.
Solution: We are given a function: g(x) = 1 – 2x + [tex]3x^2[/tex]
The average rate of change of the function as x varies from a to b is given by:
Average rate of change = f(b) - f(a) / b - a
Let a = 2 and b = 5
We have to find the average rate of change of g(x) as x varies from 2 to 5.
So, the average rate of change of g(x) is given by:
Average rate of change = g(5) - g(2) / 5 - 2
= [1 - 2(5) + 3([tex]5^2[/tex])] - [1 - 2(2) + 3([tex]2^2[/tex])] / 3
= [1 - 10 + 75] - [1 - 4 + 12] / 3= 66 / 3= 22
Therefore, the average rate of change of the function as x varies from 2 to 5 is 22.
An average rate of change is the amount that the function changes on average over a specified interval.
The formula for average rate of change is given as the change in the function value divided by the change in x value for two distinct points on the function.

To make cleaning easier, a rectangular horse trough will be lined with plastic. The trough is 40 inches long, 14 inches wide, and 24 inches deep. How many square inches of plastic are needed to line the trough? Count only the trough's five faces. A net containing 5 rectangles. Two rectangles have length of 40 inches and width of 14 inches. Two rectangles have length of 14 inches and width of 24 inches. One rectangle has length of 40 inches and width of 24 inches.
Using the area formula for the rectangle, we can find that 2752 in² of plastic is needed to line the trough.
Define area?To determine the area a rectangle occupies within its perimeter, apply the formula for calculating a rectangle's area. Multiplying the length by the width yields the area of a rectangle (breadth).
As a result, the area of a rectangle with the length and breadth l and w, respectively, is calculated as follows. L × W = the rectangle's area. Hence, the area of a rectangle is equal to (length width).
Now in the given question,
We have 5 faces of the cuboid.
Now to find the total area of the required space we have to find the area of all the rectangles.
Area of rectangle with dimensions, l = 40inches and b = 14 inches.
Area = l × b
= 40 × 14
= 560in²
Now there are 2 rectangles with the same dimensions, so the total area = 560 + 560 = 1120in².
Now area of rectangles with dimensions, l = 14 inches and b = 24 inches.
Area = l × b
= 14 × 24
= 336in².
There are 2 rectangles with the same dimensions, so area = 336 + 336 = 672in².
Area of the final rectangle = l × b
= 40 × 24
= 960in².
So, the total required area = 1120 + 672 + 960 = 2752in².

How to solve the system by elimination?To solve the system by elimination, we want to eliminate one of the variables, either x or y, from one of the equations. To do this, we need to find a multiple of one equation that cancels out one of the variables in the other equation.
We can eliminate x by multiplying the first equation by -4 and adding it to the second equation:
[tex]-4(ax+3y) + (4x+5y) &=\\ -4(7) + 15\(-4a+4)x + (5-12)y &=\\ -13\ (4-4a)x - 7y &= -13[/tex]
By adding the first equation to the second equation and multiplying it by -4, we can get rid of x:
[tex](4-4a)x-7y=13\\4x+5y=15[/tex]
We can eliminate y by multiplying the second equation by 7 and subtracting it from the first equation:
[tex](4-4a)x - 7y &=\\ -13-28x - 35y &=\\ -105[/tex]
Simplifying this last equation, we get:

pizzas are sized by diameter. what percent increase in area results if chantel's pizza increases from a 10-inch pizza to a 12-inch pizza?
Step-by-step explanation:
Area of circle = pi r^2
10 inch = pi (5)^2 = 25 pi
12 inch = pi (6)^2 = 36 pi
12 inch is 11pi bigger
percentage: 11 pi is what percentage of 25 pi ?
11 pi / 25 pi x 100% = 44 % bigger
The area of a pizza increases with the square of the diameter. Therefore, a 10-inch pizza has an area of [tex]π*(10/2)^2= 78.54[/tex] square inches, and a 12-inch pizza has an area of [tex]π*(12/2)^2 = 113.10[/tex] square inches. This is an increase of 113.10 - 78.54 = 34.56 square inches, or an increase of 44.2%.
To explain further, the diameter of a pizza is measured from one side to the other through the center of the pizza. As the diameter of the pizza increases, the area of the pizza increases. This is because the area of a pizza is calculated as [tex]π*(d/2)^2[/tex], where d is the diameter. So, if the diameter increases, the area increases as well.
For example, if a 10-inch pizza has an area of 78.54 square inches, a 12-inch pizza would have an area of 113.10 square inches. This is an increase of 113.10 - 78.54 = 34.56 square inches, or an increase of 44.2%. This is because the diameter of the pizza has increased by 2 inches (10 inches to 12 inches), and the area has increased by 44.2%.
It is important to note that increasing the diameter of the pizza does not just increase the circumference of the pizza, but also the area. The increase in area is directly related to the increase in diameter, and can be calculated by taking the difference between the areas of the two pizzas.
