The price of a carton of milk is $1.00
The given parameters are:
Number of students, n = 18Option A = 8Since 8 chose option A, it means that 10 would choose option B
So, the equation that represents when both price are equal is:
[tex]8(2x + 0.5) = 10(x + 1)[/tex]
Where
2x + 0.5 represents the unit price of option A
x + 1 represents the unit price of option B
Open the brackets
[tex]16x + 4 = 10x + 10[/tex]
Collect like terms
[tex]16x - 10x = 10 - 4[/tex]
Evaluate the like terms
[tex]6x = 6[/tex]
Divide
[tex]x = 1[/tex]
Hence, the price of a carton of milk is $1.00

Answer:
16 inches
Step-by-step explanation:
What we know:
The equation y = 3/4x shows the diameter of a trees in x inches gained in y years.
We know y, which is 12, so this becomes x = 4/3y (or x = 4y/3)
x = 4(12)/3
x = 48/3
x = 16
The predicted diameter will be 16 inches.
(Just put 16 in the blank.)
Write the explicit rule for the given the sequence: 125, 25, 5, ...
Answer:
An=125(1/5)^n-1
Step-by-step explanation:
r=common ratio
A1= first term in the sequence
I hope this helps some
The given series 125, 25, 5, ... is a geometric progression thus the general term will be An=125[tex](\frac{1}{5}}) ^{n-1}[/tex].
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
The given GP series is 125, 25, 5, ...
First term a = 125
Common ratio = 25/125 = 1/5
The nth term will be given as ar^(n-1)
Thus, An=125[tex](\frac{1}{5}}) ^{n-1}[/tex].
Hence "The given series 125, 25, 5, ... is a geometric progression thus the general term will be An=125".

Answer:
5/2
Step-by-step explanation:
The 5^-3 and 5^6 cancel out to be 5^3. Then the 5^3 cancels out with the 5^2 in the denominator and leaves you with just a 5. The 2^2 makes the 2^3 in the denominator just 2. So, you are left with 5/2! Hope this helps.
Can someone help me with this
Answer:
No, there is 3 times the amount of not yellow chalk than yellow chalk. This proves that the friend is wrong because this exceeds the given total amount of chalk, being 12. If the friend was correct there would be 24 pieces of not yellow chalk and 32 pieces of chalk in total.
The correct pieces of not yellow chalk is 9. The correct pieces of yellow chalk is 3. this can be solved by dividing the total, 12, by 4, because that is the total amount of units. This solves for one unit. Once you know the value of one unit, you can find the total of each type of chalk.

(r) = -3r + 3
Which graph represents the inverse of function ?
9514 1404 393
Answer:
C. graph Y
Step-by-step explanation:
Starting with f(r) = -3r +3, the inverse function can be found from ...
r = f(y)
r = -3y +3
r -3 = -3y
(r -3)/-3 = y
y = -1/3r +1
The inverse function will have a slightly negative slope and a y-intercept of 1. This matches graph Y.

The statement that the two triangles are similar based on the given figure is false.
What are Similar Triangles?Two triangles are said to be similar if the triangles are of the same shape but different size. The angles of the triangle will be equal and the sides are proportional.
So, we know that two similar triangles will have all the corresponding angles equal to each other.
Given two triangles EFG and HJK.
Also, given that,
EG = 8 and HK = 16
EG/ HK = 8/16 = 1/2
∠E = ∠H = 90°
There are no other information given.
If one more corresponding angles are equal, we can use ASA, AAS or AA property, and if one more corresponding side are proportional, we can use SAS postulate.
In this case, we cannot say two triangles are similar.
Hence the statement is false.

Jada has read 3/5 of a book. She read 75 pages so far. How many pages are in the whole book
Step-by-step explanation:
3/5 of the book = 75 pages
5/5 of the book = 75 * (5/3) = 125 pages
Hence there are 125 pages in the whole book.
Answer:
Concept: Data Analysis
Jada has read 60% of the book So 60% of the book is 75 pages We want to find the whole count of pages An easy way to do this is to see that for every 20% you have 15 pages You need 40% So its 30 pages So 75+30= 105 pageswhat is the percent increase in 22 to 30
Answer:

How do I turn a decimal into a whole number? :)
There is a confusion here. “Decimal” is not a number set. “Whole numbers” is.
“Decimal” has been used to mean three different things about the representation of numbers:
- Numbers written using a base 10 place value system
- The decimal point that separates the integer and fractional parts of a number written in base 10. (Some countries use a comma. Some folks refer to the point used for this purpose in other bases as a decimal too for extra confusion.)
- A number written in the above form that has some numerals, probably nonzero, written to the right of the point. In other words, a number written in decimal form with a nonzero fractional part.
I'm guessing that the usage in this question is referring to the third meaning of “decimal” and will interpret the question as being not about representation of numbers but about transformation of numbers.
To wit, “What are some popular ways real numbers with nonzero fractional parts can be mapped to integers?”
I hope this is the correct interpretation.
There are a few common ways:
- Round towards zero: Ignore the fractional part and keep only the integral part.
- Floor: Take the greatest integer less than the number in question.
- Ceiling: Take the least integer greater than the number in question.
- Round to the nearest integer: Ignore the fractional part if it's less than a half. Otherwise, round away from zero.
These are the main ways of picking integers close to the number in question, but obviously, there are infinitely many ways to map sets of real numbers to mergers, so it is unclear if any of these are what the asker was looking for.

The correct answer is 960 yards
Explanation:
The first step to answer this question is to calculate the distance Alan traveled. Additionally, to calculate this use the time (90 seconds) and the speed (32 ft/s) by considering distance equals speed multiplied by time.
D (Distance) = s (speed) x t (time)
D = 32 ft/s x 90 s
D= 2880 ft
This means the total distance was 2880 feet; however, the answers are provided in yards and the feet need to be changed to yards. Follow this process:
1 foot = 0.3333 yards
2880 ft x 0.3333 yards = 959.99 yards which can be rounded as 960 yards.
A yoga instructor offers two options for classes. Option 1: $40 joining fee and $20 per class Option 2$0 joining fee and $25 per class After how many classes will both options have the same cost?
Answer:
The indifference point is 8 classes.
Step-by-step explanation:
Giving the following information:
Option 1:
$40 joining fee and $20 per class
Option 2:
$0 joining fee and $25 per class
First, we establish the total cost formulas:
Option 1= 40 + 20x
Option 2= 0 + 25x
x= number of classes
Now, we equal both formulas and isolate x:
40 + 20x = 25x
40=5x
8=x
The indifference point is 8 classes.
Prove:
Option 1= 40 + 20*8= $200
Option 2= 0 + 25*8= $200
