Direct variation is represented by the formula [tex]\frac{y}{x} = k[/tex]
where k is the constant of variation.
So here, since we know that x = 24 and y = 8,
the constant of variation must be equal to 8/24.
if we write 8/24 in lowest terms, we have 1/3.
So 1/3 = k.

With a coupon, you can get a pair of shoes that normally cost $84 for only $72. What percentage was the discount. Please give the step by step explanation!
Answer:
14.28%
Step-by-step explanation:
Given that,
You can get a pair of shoes that normally cost $84 for only $72.
We need to find the discount percentage. So, it can be calculated as follows :
[tex]\%=\dfrac{84-72}{84}\times 100\\\\\%=14.28\%[/tex]
So, the required percentage is 14.28%.

Suppose a loaded die has the following probability model: If this die is thrown and the top face shows an odd number, what is the probability that the die shows a 1
Answer:
the probability is 0.6
Step-by-step explanation:
The computation is shown below:
Let us assume the X would be the number appear on the top face
Now
= P(X = 1) ÷ P(X = 0)
= 0.3 ÷ 0.3 + 0.1 + 0.1
= 0.3 ÷ 0.5
= 0.6
hence, the probability is 0.6
a gumball machine gives you no gum if you insert 5c, 5 gumballs if you insert 10c , 10 gumballs if you insert 15c and 15 gumballs if you insert 20c. how many gumballs could you expect to receive if you insert 35c?
Answer:
30
Step-by-step explanation:
create a function where x is the money you insert in cents and y is the amount of gumballs you get.
y = x - 5 (meaning you get five less gumballs than the amount of cents you insert)
Therefore, when x = 35:
y = 35 - 5 = 30.
You will get 30 gumballs.

b) 2(x-3) + X = 5x-2(x+5)
Answer:
X=x−4
Step-by-step explanation:
2(x−3)+X=5x−2(x+5)
Use the distributive property to multiply 2 by x−3.
2x−6+X=5x−2(x+5)
Use the distributive property to multiply −2 by x+5.
2x−6+X=5x−2x−10
Combine 5x and −2x to get 3x.
2x−6+X=3x−10
Subtract 2x from both sides.
−6+X=3x−10−2x
Combine 3x and −2x to get x.
−6+X=x−10
Add 6 to both sides.
X=x−10+6
Add −10 and 6 to get −4.
X=x−4

A civil servant had a salary of Rs. 9600. Tax up to
Rs. 85000 per year would be exempted. If he paid
Rs. 377.50 as a tax per month, how much percent of
tax was imposed ?
(Ans: 15 %
Answer:
Step-by-step explanation:
The question is misleading. It was not specified that his salary is Rs 9,600 per month. That is 115,200 yearly. Of that, 115,200- 85,000 = 30,200 is taxable.
tax = Rs 377.50/month = Rs 4,530/year
4,530/30,200 = 0.15 = 15%
math algebra HELP!!!!
Answer:
y = 32
Step-by-step explanation:
[tex]\frac{1}{2} y + 22 = 38[/tex]
Subtract 22 from both sides to isolate the y variable.
[tex]\frac{1}{2} y = 16[/tex]
Divide both sides by [tex]\frac{1}{2}[/tex], which is the same as multiplying by 2.
y = 32
1/2y + 22 = 38
-22 -22
1/2y = 16
x2 x2 ---> This is because if 1/2y = 26, that means y times 1/2 is 26, but we want to know what y times 1 is because y times 1 is equal to y so we multiply by 2 because 1/2 times 2 equals 1.
y = 32

What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
Expression: 3a² + 2b²
Not, put the value of a= -3 and b=6 we get
= 3a² + 2b²
= 3(-3)² + 2(4)²
= 3 x 9 + 2 x 16
= 37 + 32
= 69
Hence, the value of expression is 69.

Elaine drives her car 180 miles and has an average of a certain speed. If the average speed had been 5mph more, she could have traveled 200 miles in the same length of time. What was her average speed?
Answer:
45 mph
Step-by-step explanation:
Using the equation d = rt, we can rearrange the equation to be t = d/r
Since the amount of time was the same, we can set d/r equal to each other for both speeds.
Let x represent the average speed.
[tex]\frac{d}{r}[/tex] = [tex]\frac{d}{r}[/tex]
[tex]\frac{180}{x}[/tex] = [tex]\frac{200}{x+5}[/tex]
Cross multiply and solve for x:
200x = 180x + 900
20x = 900
x = 45
So, the average speed was 45 mph
A soccer team gets three points for a win, one point for a tie, and zero points for a loss. The team plays ten games and has three more wins than losses. What is the greatest possible number of points the team could have?
Answer: 19.
Step-by-step explanation:
The highest you can go is 6 and 3 because you can't do 7 and 4. 6 wins would add up to 18 points. The one game that is missing we can say could be a tie, which would add 1 point, making it 19 possible points.
Answer:
Highest number of wins and losses can only be 6 & 3 and if u take 7 & 4 as taking 7&4 will make total 11 and we know that there was only 10 games.
So we can conclude like this
Number of wins: 6
Number of losses: 3
Number of draws: 1
Thus the points will be, (6*3)+(3*0)+(1*1)
18+0+1
=19 points

The function f(x) =5x coverts x nickels to pennies. Find a function that converts X Pennys to Nichols then convert 50 pennies to Nichols. 
Answer:
[tex]f'(x) = \frac{1}{5}x[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 5x[/tex] --- Nickel to Penny
Required
Determine the function that converts penny to nickel
This question implies that we determine the inverse of the function.
We have:
[tex]f(x) = 5x[/tex]
Represent f(x) with y
[tex]y = 5x[/tex]
Swap the positions of x and y
[tex]x = 5y[/tex]
Make y the subject by dividing both sides by 5
[tex]\frac{1}{5}x = \frac{5y}{5}[/tex]
[tex]\frac{1}{5}x = y[/tex]
[tex]y =\frac{1}{5}x[/tex]
Replace y with f'(x)
[tex]f'(x) = \frac{1}{5}x[/tex]
Hence, the function that converts x pennies to nickels is [tex]f'(x) = \frac{1}{5}x[/tex]

william runs 40 yards in 4.5 seconds. at the same pace how long will he take to run 100yards?
Answer:
11.25 seconds
Step-by-step explanation:
first, we need to figure how how far william can run per second
we can find this by 40 ÷ 4.5
= 8.889 per second
so we know that 8.889 • s (seconds) = 100
8.889s = 100 divide both sides by 8.889
s = 11.25 seconds
Answer:
William will take 11.25 seconds to run 100 yards
Step-by-step explanation:
Constant Rate
William runs 40 yards in 4.5 seconds. The rate of change of the distance is
[tex]\frac{40}{4.5}[/tex]
To run 100 yards, we divide by the rate obtained above:
[tex]\displaytstyle \frac{100}{\frac{40}{4.5}} =100*\frac{4.5}{40} =11.25[/tex]
William will take 11.25 seconds to run 100 yards

A.) A paint store sells exterior for $35.75 a gallon and paint rollers for $6.00 each. Write an equation in standard form for the number of gallons p of paint rollers r that a customer could buy with $190.
B.) Use your equation to determine the number of gallons of paint needed if a customer bought 6 rollers
The total price for the gallons of paint will be 35.75p
The total price for the rollers will be 6r
So the equation if the customer have 190 will be
price for gallons of paint + price for rollers = 190
35.75p + 6r = 190
(This is the equation)
