Assuming we need to find out what 20% off of the prices listed is, we can set up equations for each of them, where x is the original price.
New price = [tex]\frac{8}{10} x[/tex] or simplified to [tex]\frac{4}{5} x[/tex]
So, putting the original prices through the formula, we get these values:
$15 --> $12
$12 --> $9.60
$25 --> $20
$120 --> $96
$35 --> $28
$28 --> $22.40

Answer:
280 Square Inches
Step-by-step explanation:
This problem is formatted quited weirdley, but Im giving my best hand forward to solve it.
We are given 2 rectangular fingures, and we need to figure out the total area Tara requires for her project.
When approaching these problems I preferably like to form equations.
Area of Rectangle 1 + Area of Rectangle 2 = Total Area
Now we plug in the values
(15x12) + (10x10) = T
180 + 100 = T
280 = T
Factor this expression

Which expression is equivalent to 6f+f?
Answer:
A
Step-by-step explanation:
This is because 6f+f is just 7f.
f f f f f f+f = fffffff
Soooo, ONLY A gives us 7f when added together again.
f+5f+f=7f.
f+ f f f f f +f = fffffff
Answer:
[tex]f + 5f + f[/tex] is equivalent to [tex]6f + f[/tex].
Step-by-step explanation:
You can plug in any numbers to both expressions and they will always have the same outcome.
For example, let's plug in 2.
[tex]6f + f\\6(2) + 2\\12 + 2 = 14[/tex]
[tex]f + 5f + f\\2 + 5(2) + 2\\2+10+2 = 14[/tex]

How much area, in square yards, will have red flowers?
Select locations of points
• Point A (-4,4)
• Point B (3, 4)
• Point C (3,-2)
• Point D (-4,-2)
Use the Add Point and Connect
Line tools to create the rectangle
ABCD.
Answer:
Part B : 42
Part C : 7
Step-by-step explanation:
After putting in the coordinate points the width of the rectangle is 7 units and the length is 6 units. 7*6 =42. Half of this is the area of the triangle, that is 21. Further , 1/3 of 21 is the same as 21 divided by 3, which equals 7.
2. Jessica ate 45 m&m's in a competition against her classmates. Jessica ate 60% of
the total m&m's eaten. How many m&m's were eaten in the competition?
A. 24
B. 75
C.106
D.27
Answer:
B. 75
Step-by-step explanation:
Note that we can get the equation [tex]45 = 60\% \cdot x[/tex], where x is the total number of m&m's eaten. This becomes [tex]45 = \frac{60}{100}x \Rightarrow 45 = \frac{3}{5}x \Rightarrow x = 75[/tex]

What is the unknown fraction?
three tenths plus blank equals sixty one hundredths
A. thirty one hundredths
B. fifty eight hundredths
C. sixty four hundredths
D. one hundred and twenty two hundredths
Answer:
A. 31/100
Step-by-step explanation:
Change 3/10 to hundreds:
3/10 × 10/10 = 30/100
The denominator (the bottom number) must be 100.
61 - 30 is 31.
The missing number is 31/100. See image.
A team won 60% of the games they played. If the team lost 12 games, how many games did they win?
well, we know they won 60% of the games, meaning 100% - 60% = 40%, they lost 40% of the games, and we also know that that number is 12.
[tex]\begin{array}{ccll} \%&amount\\ \cline{1-2} 40 & 12\\ 60& x \end{array} \implies \cfrac{40}{60}=\cfrac{12}{x}\implies \cfrac{2}{3}=\cfrac{12}{x} \\\\\\ 2x=36\implies x=\cfrac{36}{2}\implies x=18[/tex]

Answer:
Step-by-step explanation:
It looks like the solution is the first set of data
{1, 4, 6, 10, 12, 14, 19, 20, 25 }
because: median is 12, Q1 is 6, Q3 is 19, yet the range is from 1 to 25 while the range of the box and whisker plot is 1 to 24.

Follow the rules to create two number sequences that go to the fifth term each. Rule 1: Multiply by 2 starting at 10. Rule 2: Subtract 4 starting from 24. What is the first term that appears in both sequences? (2 points) Group of answer choices 10 14 20 26
Answer:
Step-by-step explanation:
Created Sequences
S1: 10 20 40 80 150
s2:24 20
The first term that appears in both sequences is the second term. Both of them equal 20.
I don't think you have to go any further once you get the first term.
Method
S1: Multiply by 2 starting with 10.
10*2 = 20
20*2 = 40
S2: Start at 24 and subtract 4
24 - 4 = 20
20 - 4 = 16
16 - 4 = 12

To number the pages of a book,2022 digits are used. How many pages are in the book?
Answer:
710
Step-by-step explanation:
Numeration of pages goes from 1.
9 pages with 1-digit numbers, from 1 to 9.
90 pages with 2-digit numbers, from 10 to 99.
So, 2*90 + 9 = 189 digits are just used to numerate 9 + 90 = 99 pages.
The rest of numbers are 3-digit.
2022-189/3 = 611 pages with 3-digit numbers.
Total pages = 9 + 90 + 611 = 710.
The number the pages of a book,2022 digits are used there are 8880 pages in the book.
Let's assume there are "x" pages in the book. Each page number requires a certain number of digits to represent. The number of digits required to represent a page number depends on the value of the page number itself.
For example:
Page numbers from 1 to 9 require 1 digit each.
Page numbers from 10 to 99 require 2 digits each.
Page numbers from 100 to 999 require 3 digits each.
And so on.
Since we're given that 2022 digits are used in total, we can set up an equation based on the above observations:
Number of 1-digit page numbers + Number of 2-digit page numbers + Number of 3-digit page numbers + ... = 2022
Now let's solve this equation to find the number of pages:
Number of 1-digit page numbers = 9 (from 1 to 9)
Number of 2-digit page numbers = 90 - 10 + 1 = 81 (from 10 to 99)
Number of 3-digit page numbers = 900 - 100 + 1 = 801 (from 100 to 999)
Substituting these values into the equation:
9 + 81 + 801 + ... = 2022
Now we need to find the number of terms in this sequence. Each term corresponds to a certain number of digits, and we want to find the smallest number of digits that will exceed 2022. We can try different numbers of digits until we find the correct one:
Number of 4-digit page numbers = 9000 - 1000 + 1 = 8001
Adding the terms up:
9 + 81 + 801 + 8001 = 8880

Compound interestThis is an interest on an amount of money. The formula for calculating the compound interest is expressed as;
A = P(1 + r)^t
P is the principal = 100
r is the rate = 6% = 0.06

6 > x > −9
−6 < x < 9
[Hello, blueface1728]
Answer:
[D] −6 < x < 9
Step-by-step explanation:
So, if a < u <b then a < u and u <b
-7 < x - 1 and x -1 < 8
Solving
-7 < x - 1 = x > -6
x - 1 < 8 = x < 9
Combine the intervals
-6 < x < 9
Now looking at the answer choice :
6 < x < 9
−6 > x > 9
6 > x > −9
−6 < x < 9
Thus, the answer is [D] −6 < x < 9

Brooke has $7 in an account that earns 10% interest compounded annually.
To the nearest cent, how much will she have in 2 years?
Assuming that no transaction happens in her account for those 2 years, the amount that Brooke will have in 2 years for given case is $8.47
How to find the compound interest?If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:
[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]
We're specified that:
Initial amount in bank of Brooke = p = $7Interest rate = r = 10% = 0.10 (in decimal form), compounding annually.Due to annual appliance of the interest, we have n = 1The time for which this compounding will be done is t = 2 years.Thus, we get the final amount's value (after 2 years of compounding) for this case as :
[tex]a = p(1 + \dfrac{r}{n})^{nt}\\\\a = 7(1 + 0.10)^2 = 7 \times (1.1)^2 = 7 \times 1.21 = 8.47 \: (\rm in \: dollars)[/tex]
