Beverly is trying to prove that △PQR is a right triangle.
The vertices of △PQR are at P(-2,5), Q(-1,1), and R(7,3). Which TWO slope calculations
can she use to correctly show that △PQR is a right triangle?
Select TWO of the answers below.
Answer:
Triangle PQR is a right triangle. First we have to find the length of each side of the triangle. This can be done using the points provided, along with the Pythagorean theorem, which is a^2+b^2=c^2. PR^2 = (7- -2)^2+(3-5)^2 = 85 => PR = sqrt(85) QR^2 = (7- -1)^2+(3-1)^2 = 68 => QR = sqrt(68) QP^2 = (1-5)^2+(-1 - -2)^2 =17 => QP = sqrt(17) Now that we have the sides of the triangle, we can put them into the Pythagorean theorem again to see that it works out: (Sqrt(17))^2 + (sqrt(68))^2 = (sqrt(85))^2 17 + 68 = 85 85 = 85 Since the Pythagorean theorem works for right triangles, the triangle is indeed a right triangle.

A homeowner sections off part of her backyard for a vegetable garden. The width of the garden is 4 ft shorter than the length. The perimeter of the garden is 52 ft. What are the dimensions of the garden?
Answer:
length = 15ft
width = 11ft
Step-by-step explanation:
p = 2L + 2w = 52ft
w = L - 4
Substitute: 2L + 2(L-4) = 52
Simplify and solve:
2L + 2L - 8 = 52
4L - 8 = 52
4L = 60
L = 15
w = 15-4 = 11
Check:
2(15) + 2(11) = 52?

A student would like to estimate the average temperature using a thermometer that she places outside. Prior to the start of summer, the student randomly selects 10 days that she will use as her sample. On each of those 10 days, she records the outside temperature at 3 p.m. Assume that all conditions for inference have been met. (a) After collecting her data, the student calculates a 95% confidence interval to estimate the population mean. In this case, what is the population? the temperature all days for that summer the time of the day the 10 days (b) Suppose the calculated confidence interval is (72, 88) degrees Fahrenheit. What is the value of the point estimate (in degees Fahrenheit)? °F (c) Based upon your calculated point estimate and the confidence interval given in Part (b), what is the estimated margin of error (in degees Fahrenheit)? °F
a) The population of the confidence interval is given as follows: The temperature all days for that summer.
b) The point estimate of the interval is of: 80 degrees Fahrenheit.
c) The margin of error of the interval is of: 8 degrees Fahrenheit.
What are the features of the confidence interval?A confidence interval for a population parameter is built taking a sample of this population.
Then, the interval for the population mean is given as the sample mean plus/minus the margin of error.
The sample in this problem is given as follows:
The temperature for 10 days of summer.
Hence the population is of:
The temperature all days for that summer.
The interval in this problem is given as follows:
(72, 88).
The point estimate is the mean of the bounds, hence:
Point estimate = (72 + 88)/2 = 80.
The margin of error is half the difference of the two bounds, hence:
Margin of error = (88 - 72)/2 = 8.

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 equation be represented as A
Now , the value of A is
f ( x ) = ( x + 2 )²( x -3 ) be equation (1)
Now , on simplifying the equation , we get
f ( x ) = ( x + 2 )²( x -3 )
f ( x ) = ( x² + 4x + 4 ) ( x - 3 )
Now , multiplying each term with ( x - 3 ) , we get
f ( x ) = ( x - 3 ) x² + ( x - 3 ) 4x + ( x - 3 ) 4
f ( x ) = x³ - 3x² + 4x² - 12x + 4x - 12
On simplifying the equation ,we get
f ( x ) = x³ + x² - 8x - 12

Mr. Clark is contemplating which chauffeured car service to take to the airport. The first costs $28 up front and $1 per kilometer. The second costs $3 plus $2 per kilometer. For a certain driving distance, the two companies charge the same total fare. What is the total fare? What is the distance?
Answer:
The total fare is $53, and the distance is 25
Step-by-step explanation:
The equation we can use for the first car would be:
28 + (1×k) = fare (f)
The equation we can use for the second car would be:
3 + (2×k) = f
If we were to plug in 20 into the equations, it would look like this:
28 + (1×20) = 48 (first car)
3 + (2×20) = 43 (second car)
As you can tell, the prices aren't matched up just yet.
Let's plug 25 into the equations.
28 + (1×25) = 53
3 + (2×25) = 53
The number of kilometers traveled is 25, and the price is $53

Write a situation that can be represented by 2.5x - 15
Answer:
Linda starts the month with $15 in debt. Each hour, she makes 2.5 dollars. How many hours will it take for Linda to get out of debt?
A situation that can be represented by the expression 2.5x - 15 is given below.
Let's consider a situation where you are tracking the amount of money you earn from selling handmade crafts. In this scenario, the expression 2.5x - 15 can represent your net earnings after deducting the initial investment and expenses.
Suppose you invest a certain amount of money in materials and supplies to create your crafts. The variable x represents the number of crafts you sell. Each craft generates a profit of $2.50. Therefore, the term 2.5x represents the total profit you earn from selling x crafts.
However, running a business incurs expenses. In this case, the expression -15 represents $15, which is the total expense or cost associated with producing and selling your crafts.
So, 2.5x - 15 calculates your net earnings after subtracting the expenses from the profit. It provides you with a measure of how much money you've made after covering the costs.
By plugging in different values for x, you can evaluate the expression to determine your earnings for various levels of craft sales, allowing you to analyze your profitability and make informed decisions regarding your business.

misses. Reina makes 9 baskets for every 7 misses. Who makes a basket more often?
Show your work.
The person who makes a basket more often, between Simon and Reina, is Simon
How to find who makes more baskets ?To find who makes the basket more, you need to find the percentage number of times the basket is made.
The percentage number of times the basket is made by Simon is :
= Number of baskets made / ( Number of baskets made + Number of baskets missed ) x 100 %
= 7 / ( 7 + 5 ) x 100%
= 7 / 12 x 100%
= 58.3%
The percentage number of times Reina makes the basket is :
= 9 / ( 9 + 7 ) x 100%
= 9 / 16 x 100%
= 56.25%

The total number of sandwiches they have in all on Sunday is 375 sandwiches.
The amount earned by the cafe if each sandwich cost $4.50 is $1,687.5
What is the total number of sandwiches?Ham sandwich = 35%Roast beef sandwich = 25%Turkey sandwich = 40%Total ham and turkey sandwiches = 225Total number of sandwiches = xTotal percentage of ham and turkey sandwiches = 35% + 25%
= 60%
So,
225 = 60% of x
225 = 0.60 × x
225 = 0.60x
divide both sides by 0.60
x = 225/0.60
x = 375
Hence,
Total number of sandwiches = 375
If the cafe sells all the sandwiches at $4.50 each
The total money earned by the cafe = cost of each sandwich × total number of sandwiches
= $4.50 × 375
= $1,687.5
