B. 664 in2
C. 1,120 in2
D. 1,080 in2
Answers
Answer:
1,120 in2
Step-by-step explanation:
surface area= l×w×h
=10(14)(8)
=140(8)
=1,120
The surface area of the provided prism is 1,120 square inches. Option C is the correct option.
What is surface area?Surface area of any solid or the 3 dimensional body is the area of each faces by which the solid body is enclosed.
The surface area of the prism can be calculated with the following formula.
l×w×h
The image of the prism is attached below. In the given prism, the common height is 8 in and bases of the rectangular faces are 10 in, 14 in and 8 in long.
To find the surface area of the given prism, put the values in the above formula.
surface area= l×w×h
=10(14)(8)
=140(8)
=1,120
Option C is the correct option.

Find the 25th term.
2, 10, 18, 26, 34, ...
25th term = [?]
Answers
an = a1 + (n - 1)d
Substituting the values
an = 2 + (n - 1)8
We have to find the 25th term n = 25
a25 = 2 + (25 - 1)8
a25 = 2 + (24)8
a25 = 2 + 192
a25 = 194
======================================================
Explanation:
The gap between adjacent terms is 8.
2+8 = 1010+8 = 1818+8 = 2626+8 = 34etcThe long way to get the answer would be to keep adding 8 to each term to generate the next one. You'd need to do this 20 times. There are 5 terms here already, so you need 25-5 = 20 more operations of "add 8".
I don't recommend this option. I recommend the shortcut mentioned in the next section.
--------
The shortcut would be to find the nth term of the arithmetic sequence
\(a_1 = 2 = \text{ first term}\\\\d = 8 = \text{ common difference}\\\\a_n = \text{ nth term}\\\\a_n = a_1 + d(n-1)\\\\a_n = 2 + 8(n-1)\\\\\)
As a check, plug n = 1 into that formula to get \(a_1 = 2\). Plug n = 2 to get \(a_2 = 10\) and so on. I'll leave this check portion for the student to do.
--------
The last step is to plug n = 25 into that formula to determine the 25th term.
\(a_n = 2 + 8(n-1)\\\\a_{25} = 2 + 8(25-1)\\\\a_{25} = 2 + 8(24)\\\\a_{25} = 2 + 192\\\\a_{25} = 194\\\\\)
The final answer is 194-------
Extra section (optional):
We can use a spreadsheet to generate the 25 terms. This is to help check the answer.

What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The difference between the numbers m and n is given by putting a minus sign between the numbers m and n.
⇒ m - n
Then one-third of the expression will be given as,

A toy company's total payment for salaries for the first two months of 2012 is $40,765. Write and solve an equation to find the salaries for the second month if the first month’s salaries are $10,205.
Answers
Answer:

12,455 + x = 23,894
x = 10,560
Step-by-step explanation:
Let's say that the variable 'x' represents the salaries for the second month, so out equation would be:
10,205 + x = 23,894
To solve, we must isolate the variable by subtracting 12,455 from both sides:
10,205 + x = 23,894
-10,205 -10,205
x = 10,560
So, the second month's salary was $10,560
Step-by-step explanation:
Answer: x = $30,560
Step-by-step explanation:
1. Let the second month payment be x
2. The first month + The second month = both of the months
3. So substituting: 10,205 + x = 40,765
4. Subtract 10,205 from both sides: x = 30,560
Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

E. Mark has $20 in his bank account. He saves $5 each week. How much money does Mark have in his account after 9 weeks? Use w to represent the number of weeks and t to represent the total amount Mark has after any number of weeks.
1) One-step equation:
5x + 3 = 18
Solution:
Subtract 3 from both sides to isolate the variable:
5x + 3 - 3 = 18 - 3
5x = 15
Divide both sides by 5 to solve for x:
5x/5 = 15/5
x = 3
2) One-step equation:
4y - 7 = 9
Solution:
Add 7 to both sides to isolate the variable:
4y - 7 + 7 = 9 + 7
4y = 16
Divide both sides by 4 to solve for y:
4y/4 = 16/4
y = 4
3) Equation with fractions:
2/3 x + 1/4 = 1/2
Solution:
Subtract 1/4 from both sides to isolate the variable:
2/3 x + 1/4 - 1/4 = 1/2 - 1/4
2/3 x = 1/4
Multiply both sides by 3/2 to solve for x:
(2/3 x) * (3/2) = (1/4) * (3/2)
x = 3/8
4) Equation with fractions:
3/4 z - 1/2 = 1/8
Solution:
Add 1/2 to both sides to isolate the variable:
3/4 z - 1/2 + 1/2 = 1/8 + 1/2
3/4 z = 5/8
Multiply both sides by 4/3 to solve for z:
(3/4 z) * (4/3) = (5/8) * (4/3)
z = 5/6
5) Equation with distributive property:
2(x + 5) = 16
Solution:
Use the distributive property to simplify the left side of the equation:
2(x + 5) = 2x + 10
Subtract 10 from both sides to isolate the variable:
2x + 10 - 10 = 16 - 10
2x = 6
Divide both sides by 2 to solve for x:
2x/2 = 6/2
x = 3
6) Equation with decimals:
0.5x + 1.25 = 2.75
Solution:
Subtract 1.25 from both sides to isolate the variable:
0.5x + 1.25 - 1.25 = 2.75 - 1.25
0.5x = 1.5
Divide both sides by 0.5 to solve for x:
0.5x/0.5 = 1.5/0.5
x = 3
7) Real-world problem:

Which of the following is a result of shifting a circle with equation (x-2)2 +(y-3)2=25 to the left 2 units ?
A.) Both the x- and y-coordinates of the center of the circle increased by 2
B.) Both the x- and y-coordinate of the center of the circle decreased by 2
C.) The y-coordinate of the center of the circle decreased by 2
D.) The x-coordinate of the center of the circle decreased by 2
Answers
Answer:
D.) The x-coordinate of the center of the circle decreased by 2
Step-by-step explanation:
(consult the diagram attached below)
Consider a circle
(x - 2)² + (y - 3)² =25
Where (h, k ) = (2, 3) which is the center of the circle.
When we want to move the circle to the left by 2 units, it also means the the center of the circle will move 2 units to the left.
If center of the circle moves 2 units to the left, it means that the x coordinate of the center of the circle will be decreases by 2 units, while y coordinate will remain the same.
Hence the new coordinate for the center of the circle is (2-2, 3) = (0, 3)
The new equation of circle will be:
(x - 0)² + (y - 3)² =25
(x )² + (y - 3)² =25
