A prism is a three-dimensional shape with the same cross-section all the way through.
What is prism?A prism is a solid shape that is bound on all its sides by plane faces.
A prism is a type of three-dimensional (3D) shape with flat sides. It has two ends that are the same shape and size (and look like a 2D shape).It has the same cross-section all along the shape from end to end; that means if you cut through it you would see the same 2D shape as on either end.
Hence, a prism is a three-dimensional shape with the same cross-section all the way through.

Anne buys her store's art supplies from a wholesaler. She purchases 8 canvases that are 16 by 20 inches for $7.16
each. How much profit does Anne make on the sale of these 8 canvases?
OA. $35.92
OB. $45.63
OC.
$57.28
OD. $86.04
Answer:
OC. $57.28
Step-by-step explanation:
It depends on how much she sells them for.
Let's say Anne sells them for $x.
Then her profit is:
8x-(8*7.16)
=8x-57.28
To make a minimum to at least make even is $57.28 and sell for $7.16 a piece.
Anne makes a profit of $57.28 on the sale of these 8 canvases. which is the correct answer would be option (C).
What is the profit?The profit is equal to the difference between the selling price and the original cost price.
Anne purchases art supplies for her business from a wholesaler. She spends $7.16 on eight 16 by 20-inch canvases.
To calculate the profit that Anne makes on the sale of these 8 canvases, you need to know the price at which she sells them and the cost of buying them from the wholesaler. If the cost of each canvas is $7.16 and she buys 8 of them, the total cost of the canvases is :
⇒ 8 × $7.16
Apply the multiplication operation and we get
⇒ $57.28.
Therefore, she makes a profit of $57.28 on the sale of these 8 canvases.
Hence, the correct answer would be an option (C).

Answer:
Step 2.
Step-by-step explanation:
When you have a coefficient on a side of the equation that you need to get rid of, you must divide by the number. For example, in the problem:
3(x+8)² = 75
Here, you need to divide both sides by '3' instead of multiplying, which was done instead. Then you get:
(x+8)² = 25.
Therefore, his mistake was made at Step 2.

Step-by-step explanation:
The consecutive terms of the sequence have a common difference d
d = 17 - 10 = 24 - 17 = 7
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d

Random sample size of 81 are taken from an infinite population whose mean and standard deviation are 200 and 18, respectively. The distribution of the population is unknown. the mean and the standard error of the mean are?
Answer:
the mean and standard error of the mean are 200 and 2 respectively.
Step-by-step explanation:
Given that ;
the sample size n = 81
population mean μ = 200
standard deviation of the infinite population σ = 18
A population is the whole set of values, or individuals you are interested in, from an experimental study.
The value of population characteristics such as the Population mean (μ), standard deviation (σ) are said to be known as the population distribution.
From the given information above;
The sample size is large and hence based on the central limit theorem the mean of all the means is same as the population mean 200.
i.e
[tex]\mu = \bar \mu_x[/tex] = 200
∴ The mean = 200
and the standard error of the mean can be determined via the relation:
[tex]\mathbf{standard \ error \ of \ mean = \dfrac{\sigma}{\sqrt {n}}}[/tex]
[tex]\mathbf{standard \ error \ of \ mean = \dfrac{18}{\sqrt {81}}}[/tex]
[tex]\mathbf{standard \ error \ of \ mean = \dfrac{18}{9}}[/tex]
[tex]\mathbf{standard \ error \ of \ mean =2}[/tex]
Therefore ; the mean and standard error of the mean are 200 and 2 respectively.
Work out the size of angle x
Answer:
x = 121°
Step-by-step explanation:
The lower left interior angle of the triangle is adjacent to 115° and are supplementary, thus
interior angle = 180° - 115° = 65°
The angle round a point is 360°
The vertex interior angle = 360° - 304° = 56°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle, thus
x = 65° + 56° = 121°

The ideal mass for a piece of chocolate is 2.5 ounces. The actual mass for a production can vary by, at most, 0.08
ounces. Create an absolute value inequality and solve it to determine the range of chocolate masses.
Answer:
The mass of the chocolate will be between 2.42 ounces and 2.58 ounces, the absolute value inequality is: [tex]|mass - 2.5| < 0.08[/tex]
Step-by-step explanation:
The ideal mass of the chocolate is 2.5 ounces, although it can vary by 0.08 ounces, this variation can occur for greater masses and lesser ones. Therefore the actual mass of the each chocolate will sit between the ideal mass minus 0.08 and the ideal mass plus 0.08. Therefore we can construct the following inequality:
[tex]-0.08 < mass + 2.58 <0.08\\ |mass - 2.5|< 0.08\\[/tex]
The mass of the chocolate will be between 2.42 ounces and 2.58 ounces, the absolute value inequality is: [tex]|mass - 2.5| < 0.08[/tex]

if 588 digits were used to number the pages of a book how many pages are in this book.
PLEASE HELP!!!!!!
Answer: 232 pages
Step-by-step explanation:
Total digits = 588
1 digit page number:
1 to 9 = 1 × 9 = 9
Number of pages = 9/1 = 9
2 - digit page number :
10 - 99 = 2 × 90 = 180
Number of pages = 180/2 = 90
3 - digit page number :
588 - (9 + 180) = 588 - 189 = 399
Number of pages with 3 - digits = 399/3 = 133
Therefore, the total number of pages the book has is :
(9 + 90 + 133) = 232 pages
Simplify:
2[3-5(2+1)2 + 5]

Trial and error method:
the answer that satisfies the equation are: x = 1 and y = 4
Hope this helps.
Good Luck
Answer:
(1, 4 )
Step-by-step explanation:
Given the 2 equations
5x + 2y = 13 → (1)
2x + 6y = 26 → (2)
Multiplying (1) by - 3 and adding to (2) will eliminate the term in y
- 15x - 6y = - 39 → (3)
Add (2) and (3) term by term to eliminate y
- 13x = - 13 ( divide both sides by - 13 )
x = 1
Substitute x = 1 into either of the 2 equations and evaluate for y
Substituting into (1)
5(1) + 2y = 13
5 + 2y = 13 ( subtract 5 from both sides )
2y = 8 ( divide both sides by 2 )
y = 4
Solution is (1, 4 )
