Answer:
3500 students.
Step By Step;
Alright, so first we want to take %70 of 20,000 to see how many make it in, then we will do the rest.
%70 of 20,000 is equal to 14,000. So, now out of the 14,000 only 25% apply, so we have to do 25% of that.
So, now we do 25% of 14,000 which is equal to 3500.
So your answer is 3500 students enroll.
Hope this helped you. <3
Answer:
Step-by-step explanation:I think you divide 25 with 20,000=80000

Chuin has 18 coins in his pocket. He has nickels and dimes that total $1.45. How many nickels and how many dimes does he have? Write and solve a system of equations to find the answer.
A. 10 Nickles, 8 dimes
B. 9 nickles, 9 dimes
C. 8 nickles, 10 dimes
D. 7 nickles, 11 dimes
Answers
Answer:
D
Step-by-step explanation:
Let n represent the number of nickels and d represent the number of dimes Chuin has.
Since Chuin has a total of 18 coins in his pocket, the sum of the number of nickels and dimes must total 18. So:
\(n+d=18\)
The total worth of the coins is $1.45. Since each nickel is worth $0.05 and each dime is worth $0.10:
\(0.05n+0.1d=1.45\)
Solve the system. We can use elimination (you can use substitution if you prefer, it works just as perfect!). First, multiply both sides of the second equation by 10:
\(0.5n+d=14.5\)
Next, we can multiply the first equation by negative one:
\(-n-d=-18\)
Add the two equations together:
\((0.5n+d)+(-n-d)=(14.5)+(-18)\)
Simplify:
\(-0.5n=-3.5\)
Divide both sides by -0.5. So:
\(n=7\)
Chuin has seven nickels.
Using the first equation again, substitute n for 7 and solve for d:
\((7)+d=18\Rightarrow d=11\)
Therefore, Chuin has seven nickels and 11 dimes.
Our answer is D.

(conversion factors and equivalent rates homework by the way)
Answers
Answer: conversion factor is just how much of it is in another unit
Step-by-step explanation:
for example, 5280 feet are in a mile so the original rate of 15 in a hour can be turned into the equation on the first image.
Original rate (15 miles) x conversion factor (5280 feet are in a mile)
So when you multiple get 79,200 which simple means, in one hour she will go 79,200 ft. This concept can be applied to other scenarios such as feet and meter, liters and gallons, miles and kilometers, all that’s necessary is to know the conversion rate. The conversion factor is simple how much of your term is in another, this may be confusing but imagine it like this how many feet are in a yard? The answer is 3 so the conversion factor is just 3ft:1yd

Answers
Answer:
\(f^{-1}\left(f(576)\right)=\boxed{576}\)
\(f^{-1}(-7)+f(-7)=\boxed{13}\)
Step-by-step explanation:
The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).
Given table:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)
Inverse function:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)
If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).
Therefore:
\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)
The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.
The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.
Therefore:
\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Step-by-step explanation:
According to the dot plot,
3 students spend 0.5 minutes brushing their teeth.
2 students spend 1.5 minutes brushing their teeth.
1 student spends 2.5 minutes brushing their teeth.
2 students spend 3.5 minutes brushing their teeth.
1 students spend 4 minutes brushing their teeth.
So, the number set will be: {0.5, 0.5, 0.5, 1.5, 1.5, 2.5, 3.5, 3.5, 4}
Median: The middle number in a set that is ordered from least to greatest.
In this example, the median is 1.5
Mean: The sum of all values divided by the number of values.
In this set there are 9 values so we’ll divide the sum by 9
In this example, the mean would be:
(0.5 + 0.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 4) ÷ 9
18 ÷ 9 = 2
If we compare the mean to the median we can see that the mean is greater because 2 > 1.5

Ella has 0.5 lb of sugar. how much water should she add to make the following concentrations? Tell Ella how much syrup she will have in each case.
75% syrup?
Answers
Answer:
For 50% syrup, add 0.5 lb of water for 1 lb of syrup; for 5% syrup, add 9.5 lb of water for 10 lb of syrup; for 75% syrup, add 0.17 lb of water for 0.67 lb of syrup; for 1.5% syrup, add 32.8 lb of water for 33.3 lb of syrup.
Step-by-step explanation:
Let x represent the amount of water added. This means the total mass of the syrup is represented by 0.5+x.
To find percentages, we divide the part by the whole. For a 50% syrup, we need the part (sugar) compared to the whole (sugar + water) to equal 50%, or 0.50:
Multiply both sides by 0.5+x:
Using the distributive property, we have
0.5 = 0.5(0.5)+0.5(x)
0.5 = 0.25+0.5x
Subtract 0.25 from each side:
0.5-0.25 = 0.25+0.5x-0.25
0.25 = 0.5x
Divide both sides by 0.5:
0.25/0.5 = 0.5x/0.5
x = 0.5
For 50% syrup, add 0.5 lb of water. This makes the total mass 0.5+0.5 = 1 lb.
For 5% syrup, we change the equation to equal 0.05 (5% = 5/100 = 0.05) and leave everything else the same:
Multiply both sides by 0.5+x:
Using the distributive property,
0.5 = 0.05(0.5)+0.05(x)
0.5 = 0.025 + 0.05x
Subtract 0.025 from both sides:
0.5-0.025 = 0.025+0.05x-0.025
0.475 = 0.05x
Divide both sides by 0.05:
0.475/0.05 = 0.05x/0.05
x = 9.5
For 5% syrup, add 9.5 lb of water; the total mass will be 9.5+0.5 = 10 lb.
For 75% syrup, set the equation equal to 0.75:
Using the distributive property,
0.5 = 0.75(0.5)+0.75(x)
0.5 = 0.375 + 0.75x
Subtract 0.375 from each side:
0.5 - 0.375 = 0.375 + 0.75x - 0.375
0.125 = 0.75x
Divide both sides by 0.75:
0.125/0.75 = 0.75x/0.75
0.17 = x
For 75% syrup, add 0.17 lb of water; the total mass is 0.17+0.5 = 0.67 lb.
For 1.5% syrup, set the equation equal to 0.015:
Using the distributive property,
0.5 = 0.015(0.5) + 0.015(x)
0.5 = 0.0075 + 0.015x
Subtract 0.0075 from each side:
0.5-0.0075 = 0.0075 + 0.015x - 0.0075
0.4925 = 0.015x
Divide both sides by 0.015:
0.4925/0.015 = 0.015x/0.015
32.8 = x
For 1.5% syrup, use 32.8 lb of water; the total mass is 32.8+0.5 = 33.3 lb.

Bjorn is making aush, and he does not have enough of all the ingredients. He decides to make 5/6 of a whole recipe, which means he uses 1 1/4 L of water.
How much water is in a whole recipe?
____?
Answers
Answer:
1\(\frac{1}{2}\)
5/6 of the whole recipe = 1 1/4 L of water
1 whole recipe = (1 1/4 L of water) / (5/6)
To divide a fraction by another fraction, we can multiply by the reciprocal of the divisor. Therefore, we can simplify the above expression as follows:
1 whole recipe = (1 1/4 L of water) * (6/5)
Multiplying 1 1/4 L by 6/5, we get:
1 whole recipe = (5/4 L) * (6/5) = 30/20 L = 1 1/2 L
Therefore, a whole recipe of aush requires 1 1/2 L of water.
Answer: 1 1/2 L

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
