Using proportions, it is found that:
a) He has 24 videogames left.
b - I) He kept 15 videogames for himself.
b - II) The selling price of a videogame was of $800.
c) He received $15,200 from the sale of the videogames.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Item a:
He has 3/5 of 40 videogames left, hence:
3/5 x 40 = 3 x 8 = 24.
He has 24 videogames left.
Item b:
He kept 5/8 of the 24 videogames, hence:
5/8 x 24 = 5 x 3 = 15.
He kept 15 videogames for himself.
He also sold 9 videogames for $7,200, hence the selling price of one of them is:
7200/9 = $800.
Item c:
Earned $7,200 plus 500 for 16, hence:
T = 7200 + 500 x 16 = $15,200.
He received $15,200 from the sale of the videogames.

If there are eleven people on the team and nine positions, how many total arrangements of the players can be made? if amy does not want to play pitcher, then there are now people available to pitch. assuming the pitcher has already been chosen, there are ten remaining players and remaining positions. how many ways are there to arrange the remaining players and positions?
There are 19958400 ways if 9 people are selected for positions and if Amy does not want to play then the number of ways will be 1814400 if done through permutations.
Given there are 11 people and nine positions.
We have to find the number of ways in which arrangement can be done if there are 11 people and 9 positions and the number of ways to arrange if Amy doe not want to play assuming the pitcher has already been chosen.
Permutations helps us to know the number of ways an object can be arranged. It is denoted by n[tex]P_{r}[/tex]=n!/(n-r)!
where n is the number of choices available,
r is the choices.
Given that the team has 11 players while there are only 9 positions available, the number of ways is 11[tex]P_{9}[/tex]=11!/(11-9)!
=11!/2!
=19958400
Now Amy does not want to play, therefore the number of ways the remaining people can be arranged in the place of pitcher is 10. Also the positions has also decreased from 9 to 8.
Thus the number of ways in which remaining people can be arranged are: 10[tex]P_{8}[/tex]=10!/(10-8)!
=10!/2!
=1814400
Hence the number of ways in which 11 people are arranged is 19958400 and the number of ways in which the remaining players are arranged is 1814400.

Casper has some whipping cream that is 18% butterfat and some milk that is 4% butterfat. He wants to make 500 ML of them that is 12%, percent butterfat.
Here's a graph that shows a system of equations for this scenario where x is the volume of whipping cream he uses and y is the volume of milk he uses.
See Correct Answer attached!
The solution to the system of equations from the graph is x = 285.7 and y = 214.3
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent the the volume of milk he uses and x the volume of whipping cream he uses. Hence:
x + y = 500 (1)
Also:
0.18x + 0.04y = 500(0.12) (2)
From the graph:
x = 285.7 and y = 214.3

Given a normally distributed data set with the mean = 51 and the standard deviation = 12, according to the empirical rule, what percent of the data points are above 27?
The percentage of data points that are above 27 are; 2.28%
How to use the empirical rule in statistics?We are given;
Mean; μ = 51
Standard deviation; σ = 12
Sample mean; x' = 27
Thus, formula for z-score is;
z = (x' - μ)/σ
z = (27 - 51)/12
z = -2
Now, from the empirical rule of normal distribution graph attached, we see that at z = -2, the percentage is 95.44%. However, we want to find the percentage that lie above 27. Thus, this is (100% - 95.44%)/2 = 2.28%

[tex]\frac{20}{3}\times\frac{9}{2} \\\\\frac{180}{6}\\\\\ =30[/tex]
Answer:
Hello! the answer to this question is 30.
Step-by-step explanation:
To solve for the quotient, we have to convert the mixed number to an improper fraction:
[tex]6\frac{2}{3} = \frac{6*3 + 2}{3} = \frac{20}{3}[/tex]
When dividing fractions, we have to flip the divisor to its reciprocal. When doing so, the divisor [tex]\frac{2}{9}[/tex] becomes [tex]\frac{9}{2}[/tex].
Now that we have the reciprocal, the operation will change from division to multiplication. We can take the final steps to solve the problem:
[tex]\frac{20}{3} * \frac{9}{2}[/tex]
This leaves you with a result [tex]\frac{180}{6}[/tex]. This can further be simplified by doing 180 ÷ 6 to get 30.
Therefore, the quotient is 30.

$4512.6
How much money can Marvin spend each month, on average, for things like groceries, entertainment, and miscellaneous items?Savings with Marvin = $2,595.9
Scholarship amount = $958.35
Total Scholarship amount received in 2 semesters = $958.35 X 2 = $ 1916.7
Now total money that Paolo have = (Savings with Marvin) + (Total Scholarship amount received in both semesters) = $2,595.9 + $1916.7 = $ 4512.6
Tuition & books cost = $2000
Tuition & books cost for 2 semesters = $2000 X 2 = $4000
Housing cost for 2 semester contract =$1,000
Total expenses in books and housing = $4000+ $1000 = $5000

A. 2.14
B. 2.85
C. 4.75
D. 8.55
Answer:

Step-by-step explanation:
to find the average of multiple numbers, we add them together and divide by the number of values we combined
for example: the average of 1, 2, and 3:
1 + 2 + 3 = 6
6 / 3 (because there were 3 numbers) = 2
so, this average would be 2.
Let's add the weights (I have changed these into a denominator of 20, so that they can be easily added. Let me know if you need clarification on how I did so)
1 1/2 pounds, 4 3/4 pounds, 2 3/10pounds
1 1/2 = 1 10/20
4 3/4 = 4 15/20
2 3/10 = 2 6/20
1 10/20 + 4 15/20 + 2 6/20 = 7 31/20
7 31/20 = 8 11/20
8 11/20 = 8.55
8.55 / 3 = 2.85
so, the average weight of these packages is 2.85 [pounds]

The selling price of a second hand car is originally N273.000. The dealer reduces the price
in the ratio of 11:13; what is the new selling price of the car?
(a) 273,000 (b) 231,000 (c) 200,000 (d) 50,000
Answer:
231,000
Step-by-step explanation:
In the ratio of 11:13, if you plug in 13, the corresponding value is 11.
Dividing 11 by 13 shows that if you also multiply 13 by 0.846 (Rounded) it also equals 11.
So multiplying 0.846 by the original price of 273,000, we get 231,000.
The new selling price of the car will be 231,000. Then the correct option is A.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The original selling price of a used automobile is N273,000. The price is dropped by the dealer by a ratio of 11:13.
The new selling price of the car will be given as,
Selling price = 273,000 x 11/13
Selling price = 21,000 x 11
Selling price = 231,000
Thus, the correct option is A.

Enter your equation in the box.
Answer:
y = 6x+9
Step-by-step explanation:
Equations that are parallel have the same slope
y = 6x+7 is written in slope intercept form where the slope is 6 and the y intercept is 7
The lines will have a slope of 6
The point (0,9) is the y intercept because the x value is 0
We can write the equation in slope intercept form y = mx+b
y = 6x+9
Answer:
Hello! The answer is y = 6x + 9.
Step-by-step explanation:
When lines are parallel, they will have the same slope but a different y-intercept.
The y-intercept, in this case, would be (0, 9) since the x-coordinate equals 0. This leaves us with 9 as the y-intercept.
Our slope-intercept form equation will be written as:
y = 6x + 9

[tex]\boldsymbol{\sf{x=\dfrac{9\times4.40}{8}=\dfrac{39.6 }{8}=4.9 }}[/tex]
Therefore, 9 oranges would cost $4.9.
{ Pisces04 }The required cost of the amount of 4.95 dollars would be for 9 oranges.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have been given that a grocery store sells a bag of 8 oranges for $4.40.
We have to determine the cost for 9 oranges.
Let's assume x dollars would it cost for 9 oranges.
As per the given condition, we can write the ratio as:
8 oranges : $4.40 = 9 oranges : x dollars
⇒ 8 / 4.40 = 9 / x
Cross multiplication and rearrange the terms of the above equation,
⇒ 8x = 4.40×9
Divide by 8 into both sides of the equation,
⇒ x = (4.40×9)/8
⇒ x = (39.6)/8
⇒ x = 4.95
Therefore, the cost of the amount of 4.95 dollars would for 9 oranges.
