Answers
Answer:
Option D.
Step-by-step explanation:
In this question figure of pyramid is attached below the question .
Surface area of the rectangular pyramid :
Area of the Base = Length × Width
= 10 × 2 = 20 cm²
Area of Lateral #1 = [tex]\frac{1}{2}(P)(L)[/tex]
= [tex]\frac{1}{2}(10\times6.3)[/tex]
= 31.5 cm²
Area of Lateral #2 = [tex]\frac{1}{2}(8\times 2)[/tex]
= [tex]\frac{16}{2}[/tex]
= 8 cm²
Surface area of the pyramid = 20 + 2(31.5) + 2(8)
= 20 + 63 + 16
= 99 cm²
Surface area of the pyramid is 99 cm²
Answer:

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.

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.

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.

Jake's test scores for the first term of chemistry class were 78, 68, 73, 94, and 62. Which of the measures of central tendency would make Jake's test scores seem as high as possible? *
Mean
Median
Mode
Range
Answers
Answer:
Mean
Step-by-step explanation:
For the mean, his score is a 75 (78+68+73+94+62/5)
For the median, his score is a 73 (in order: 62 68 73 78 94, the middle number is the median)
There is no mode because there are no repeating numbers
For the range, his score is a 32. (highest - lowest: 94-62)
This should be right, hope it helps. :)
Answer:
Mean is the highest average out of all = 75
Step-by-step explanation:
The "range" of a list a numbers is just the difference between the largest and smallest values.
Ans The range = 94-62 = 32
Find the mean, median, mode, and range for the following list of values:
62, 68, 73, 78, 94
The mean is the usual average, so you add and then divide:
(62, 68, 73, 78, 94 ) ÷ 5 = 75
Ans = mean of 75
The median is the middle value, so first I'll have to rewrite the list in numerical order:
62, 68, 73, 78, 94
Ans = median of 73
There are five numbers in the list, so the middle one will be the 3rd number.
The mode is the number that is repeated more often than any other, so 70 if data was in 10's would be the mode.
range: 32
mean: 75
median: 73
mode: 0

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

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 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.

First we need to get the variables on one side and the constants on the other side.
So subtract 11a from both sides.
12a-11a -8 = 3
1a -8 = 3 now add 8 to each side
1a = 3+8
1a = 11
