Step-by-step explanation:
the perimeter of the given rhombus is 8√5.
To find the perimeter of a rhombus, we need to calculate the sum of the lengths of all four sides.
Given the coordinates of the points touching the graph: (-5,-3), (-1,-1), (3,-3), and (-1,-5), we can calculate the distances between these points to find the lengths of the sides.
Let's calculate the lengths of the sides:
1. Side 1: Distance between (-5,-3) and (-1,-1)
Length = √[(x2 - x1)^2 + (y2 - y1)^2]
Length = √[(-1 - (-5))^2 + (-1 - (-3))^2]
Length = √[4^2 + 2^2]
Length = √[16 + 4]
Length = √20
Length = 2√5
2. Side 2: Distance between (-1,-1) and (3,-3)
Length = √[(x2 - x1)^2 + (y2 - y1)^2]
Length = √[(3 - (-1))^2 + (-3 - (-1))^2]
Length = √[4^2 + (-2)^2]
Length = √[16 + 4]
Length = √20
Length = 2√5
3. Side 3: Distance between (3,-3) and (-1,-5)
Length = √[(x2 - x1)^2 + (y2 - y1)^2]
Length = √[(-1 - 3)^2 + (-5 - (-3))^2]
Length = √[(-4)^2 + (-2)^2]
Length = √[16 + 4]
Length = √20
Length = 2√5
4. Side 4: Distance between (-1,-5) and (-5,-3)
Length = √[(x2 - x1)^2 + (y2 - y1)^2]
Length = √[(-5 - (-1))^2 + (-3 - (-5))^2]
Length = √[(-4)^2 + 2^2]
Length = √[16 + 4]
Length = √20
Length = 2√5
Now, we can calculate the perimeter by adding the lengths of all four sides:
Perimeter = Side 1 + Side 2 + Side 3 + Side 4
Perimeter = 2√5 + 2√5 + 2√5 + 2√5
Perimeter = 8√5
Therefore, the perimeter of the given rhombus is 8√5.

Subtract 7x + 4y − 2z from 4x + 2y.
Answers
Final answer:
To subtract 7x + 4y - 2z from 4x + 2y, change the signs of the second polynomial and combine like terms, yielding a result of -3x - 2y + 2z.
Explanation:
To subtract the expression 7x + 4y − 2z from 4x + 2y, we perform subtraction of polynomials by changing the sign of each term in the expression being subtracted and then combining like terms.
Change the signs of each term in the second polynomial: −(7x) − (4y) + (2z).Add this result to the first polynomial: (4x + 2y) + (− 7x − 4y + 2z).Combine like terms: (4x − 7x) + (2y − 4y) + 2z.Simplify each group of like terms: − 3x − 2y + 2z.Therefore, the result of the subtraction is − 3x − 2y + 2z.

The original price of a ski jacket was $290. It was on sale at a 25% discount. Arianna had a coupon for an additional 10% off sale price. What price did Arianna pay for the ski jacket?
Answers
Answer:
Step-by-step explanation:
If the jacket was discounted at 25%, that means that you get 25% off, right? What it also means is that you are still paying 75%. To get to the price of the jacket on sale, multiply the price of the jacket by 75% (as a decimal):
290(.75) = 217.50
That's the price of the jacket when it is 25% off the original price. If Arianna got an additional 10% off that price, that means she got 10% off but is still paying 90%. To get to the final price that she paid, multiply the sale price of the jacket by 90% (as a decimal):
217.50(.90) = 195.75
That's what she paid in the end for the jacket (i guess not counting tax...?)
To find the price Arianna paid for the ski jacket, multiply the original price by the discount and coupon percentages.
Explanation:To find the price Arianna paid for the ski jacket, we need to calculate the discounts. First, we find the sale price by multiplying the original price by the discount percentage: $290 * 0.75 (100% - 25%) = $217.50. Then, we apply the coupon discount by multiplying the sale price by the coupon percentage: $217.50 * 0.90 (100% - 10%) = $195.75. Therefore, Arianna paid $195.75 for the ski jacket.

Brian is a junior and is paid $18.42 per hour. Calculate
his weekly wage if he works 38 hours at the normal
rate and 6 hours overtime at time-and-a-half.
Answers
Answer:
$865.74
Step-by-step explanation:
Time-and-a-half wage means you multiply the regular hourly rate by 1.5.
Regular wage: 38 hours at $18.42/hour
Time-and-a-half: 6 hours at 1.5 * $18.42/hour
Total weekly wage:
38 hours at $18.42/hour + 6 hours at 1.5 * $18.42/hour =
= 38 * $18.42 + 6 * 1.5 * $18.42
= $699.96 + $345.78
= $865.74

An assistant is in charge of ordering lunch for the monthly office meeting. For the first month, she orders ten Falafel wraps, twenty-five Turkey BLT sandwiches, and fifteen hot Ham and Swiss paninis for a total of $361.25. The next month, she orders fifteen Falafel wraps, thirteen Turkey BLT sandwiches, and twenty-two hot Ham and Swiss paninis for a total of $342.50. For the third month, she orders eight Falafel wraps, twenty-two Turkey BLT sandwiches, and twenty hot Ham and Swiss paninis for a total of $359. How much does each sandwich cost?
Answers
The solution to the system of equations will provide the cost of each sandwich type: Falafel wrap, Turkey BLT sandwich, and hot Ham and Swiss panini.
To determine the cost of each sandwich, we can set up a system of equations based on the given information.
Let's use the variables x, y, and z to represent the cost of one Falafel wrap, one Turkey BLT sandwich, and one hot Ham and Swiss panini, respectively.
From the first month's order, we can establish the equation:
10x + 25y + 15z = 361.25.
From the second month's order, we have the equation:
15x + 13y + 22z = 342.50.
And from the third month's order, we have:
8x + 22y + 20z = 359.
By solving this system of equations, we can find the values of x, y, and z, which represent the cost of each sandwich.
The solution to the system of equations will provide the cost of each sandwich type: Falafel wrap, Turkey BLT sandwich, and hot Ham and Swiss panini.

The sum of two numbers is −36. One number is 106 less than the other. Find the numbers.
Answers
Answer:
x= -71
y= 35
Step-by-step explanation:
To solve this problem you have to creat two different equations.
The first would just be the sum of the two numbers. Since they are two different numbers you will need to pick two different variables to represent them. I chose x & y.
x+y= -36
Your second equation is based off of the second sentence. It tells you that one of your numbers(I'm going to use y) needs to be subtracted by 106 in order to equal the other number (x).
x= y-106 This is how you'd write it out. Since we have one variable by itself we can use substitution to solve for y. This means you take everything (in the second equation only) on the right side of the equal side of the equal sign adn plug it in for x in your first equation.
(y-106)+y= -36 Now solve for y by adding your like terms together. The parenthesis are only there to show you what I replaced x with.
2y-106= -36 Now add the 106 over to the other side.
+106 +106
2y=70 Finally divide by 2 to get what y equals.
y=35
To find x all you do is plug 35 into one of your equations. I'm goignto use the first one to save time.
x+35= -36 Subtract the 35 over and you'll have x.
x= -71.

Angronius of Nuceria has a height of 105 inches. The mean height for all World Eaters Legion soldiers is 96.5 inches and the standard deviation of the World Eaters Legion soldiers heights is 3.6 inches.
What is the z score for Angronius's height? Round to the nearest hundredth.
Must show work to receive full credit!
What is the meaning of the Z-Score you found in Problem 1? Explain how Angronius compares to the normal World Eaters soldier.
Answers
Answer:
Z-score=2.361
Hence Angronius height about 2.3 S.D above the Eaters Legion soldiers
Step-by-step explanation:
Given:
Angronius's mean =105 inches
Eaters Legion soldiers mean =96.5 inches.
S.D for Eaters Legion soldiers =3.6
To Find:
What is the z score for Angronius's height
Solution:
Here z-score indicate the value of data above or below the given value hence ,it determines the given data lies how many S.D above the mean or below the mean
Z- score tell that How many S.D your data is away from mean.
So
Z-score for Angronius =105-96.5/3.6
=8.5/3.6
=2.366
Hence it tells that Angronius height about 2.3 S.D above the Eaters Legion soldiers
i.e 2.36*3.6= 8.5 above the Eaters Legion soldiers height
i.e 105 -96.5 =8.5
This value represents how many S.D did angronius are above the height of Eaters Legion Soldiers.
The z-score for Angronius's height is 2.36, indicating that he is significantly taller than the average World Eaters Legion soldier, standing 2.36 standard deviations above the mean height.
To calculate the z-score for Angronius's height, we use the formula: [tex]z = (X - [\mu]) / [\sigma][/tex], where X is Angronius's height, [tex][\mu][/tex] is the mean height of the World Eaters Legion soldiers, and [tex][\sigma][/tex] is the standard deviation of their heights.
Using the provided values, we have:
z = (105 - 96.5) / 3.6 = 2.36.
Therefore, the z-score for Angronius's height is 2.36 when rounded to the nearest hundredth. This means that Angronius is 2.36 standard deviations above the mean height of all World Eaters Legion soldiers. In terms of height, Angronius is significantly taller than the average World Eaters soldier.

Aseem and Stana are building model cars. Stana's car is 5 less than 2 times the length of Aseem's car. The sum of the lengths of both cars is 20 inches. Write an equation to determine the lengths of Aseem's and Stana's cars.
2x − 5 + x = 20
5 − 2x + x = 20
2x − 5 = 20
5 − 2x = 20
Answers
Answer:
2x − 5 + x = 20
Step-by-step explanation:
Let Aseem's car length be x
Then, length of Stana's car is:
2x - 5
Sum of lengths:
2x - 5 + x = 20
Final answer:
The correct equation that represents the lengths of the model cars Aseem and Stana are building is '2x - 5 + x = 20,' where x represents the length of Aseem's car.
Explanation:
The equation to determine the lengths of Aseem's and Stana's model cars is 2x − 5 + x = 20.
We can define the variable x as the length of Aseem's car, and since Stana's car is 5 inches less than twice the length of Aseem's car, Stana's car length is represented as
2x - 5.
The sum of the lengths of both cars together is 20 inches.
Therefore, the equatio becomes:
(2x - 5) + x = 20
i.e. 2x - 5 -x = 20
A recipe for 48 biscuits uses 2/2/3 cups of biscuit mix. How many biscuits are made from each cup of biscuit mix?
Answers
To determine how many biscuits are made from each cup of biscuit mix, divide the total number of biscuits (48) by the total cups of biscuit mix (2 and 2/3) to get 18 biscuits per cup.
The student asked how many biscuits are made from each cup of biscuit mix if a recipe for 48 biscuits uses 2 and 2/3 cups of biscuit mix. To find this out, we need to calculate the number of biscuits per cup of mix.
We start by writing the known ratios that one recipe of 12 biscuits requires 2 cups of flour, and we then scale this to 48 biscuits using unit conversions based on the ratios.
First, we calculate the number of biscuits made per one cup:
Divide the total number of biscuits by the total cups of biscuit mix used.
48 biscuits \/ (2 + 2/3) cups = 48 biscuits \/ (8/3) cups.
Multiply the number of biscuits by the reciprocal of cups:
48 biscuits * (3/8) cups = 18 biscuits per cup.
Therefore, one cup of biscuit mix yields 18 biscuits.
