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:
[tex](\frac{55}{2} ,\frac{37}{2} )[/tex]
Step-by-step explanation:
We have to solve this system of equations in order to find the numbers :
Let x be greater number and y be the smaller one :
[tex]\begin{cases}x-y=9\ \ \ (1)&\\ x+y=46\ \ \ (2)&\end{cases}[/tex]

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]
Which set of data is represented by the box plot?
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.
So theoretically none of those sets represents the box plot.

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.

Answer:
[tex]\frac{1}{12}[/tex]
Step-by-step explanation:
1) Construct a probability tree (check the attachment).
1.1) Change the given items/values into fractions. In this case, there are 3 entrees, each with a probability of [tex]\frac{1}{3}[/tex] because the probability of selecting a hamburger (an example that could be applied to other options too) is 1 out of the 3 options. Likewise is the case with sides and drinks; the probability of selecting fries (or vegetable) out of the two options is [tex]\frac{1}{2}[/tex], and the probability of selecting milk (or juice) out of the two options is [tex]\frac{1}{2}[/tex].
A team won 60% of the games they played. If the team lost 12 games, how many games did they win?

[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]

Solve for x: −7 < x − 1 < 8
6 < x < 9
−6 > x > 9
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

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

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]

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.

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

The equation that represent the amount in the account after t years is A = 100(1.06)^t
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
