Step-by-step explanation:
A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each small box of paper weighs 45 pounds and each large box of paper weighs 80 pounds. There were twice as many large boxes shipped as small boxes shipped and the total weight of all boxes was 1435 pounds. Determine the number of small boxes shipped and the number of large boxes shipped.
Solving a system of equations we can see that:
7 small boxes were shipped.14 large boxes were shipped.How to determine the number of boxes?
Let's define the variables:
x = number of small boxes.y = number of large boxes.With the given information we can write the system of equations:
y = 2*x
x*45 + y*80 = 1435
To solve the system, we can replace the first equation into the second one.
x*45 + (2*x)*80 = 1435
x*45 + x*160 = 1435
x*205 = 1435
x = 1435/205 = 7
x = 7
So we conclude that 7 small boxes were shipped, and then:
y = 2*x = 2*7 = 14
14 large boxes were shipped.

molly and kali are selling fruit for a school fundraiser. customers can buy small boxes of grapefruit and large boxes of grapefruit. molly sold 12 small boxes of grapefruit and 5 large boxes of grapefruit for a total of $200. kali sold 4 small boxes of grapefruit and 10 large boxes of grapefruit for a total of $200. what is the cost of one small box of grapefruit and one large box of grapefruit?
The cost of one small box is $10 and the cost of one large box of grapefruit is equal to $16.
This type of problem can be solved using linear equations.
If we consider x to be the cost of one small box and y to be the cost of one large box of fruit, the linear equations can be given as;
12x + 5y = 200
4x + 10y = 200
Multiplying the second equation by 3
12x + 5y = 200
12x + 30y = 600
Now by subtracting both equations we get;
-25y = -400
y = -400 / -25
y = 16
Now adding this value of y = 16 in the first equation;
12x + 5y = 200
12x + 5(16) = 200
12x + 80 = 200
12x = 200 - 80
12x = 120
x = 120 / 12
x = 10
Therefore, $10 is the cost of one small box and $16 is the cost of one large box of grapefruit.

What is permutation?Generally, A permutation is a rearrangement of a set of elements. In other words, it is a way to arrange a set of items in a specific order. For example, the permutations of the set {1, 2, 3} are {1, 2, 3}, {1, 3, 2}, {2, 1, 3}, {2, 3, 1}, {3, 1, 2}, and {3, 2, 1}. The number of possible permutations of a set of n elements is n!.
John is placing 8 books on the shelf in between Pride and Prejudice and Little Women.
The number of ways to arrange these 8 books is 8! (8 factorial).
since the order of the books in the first and last spots is predetermined,
The final answer is 8! = 40320ways

Your boss is still trying to save money on car rentals. You compare Alpha Car Rental, which charges $72.00 per day with unlimited free mileage, and Amazing Car Rental, which charges $22.90 plus 30 cents per mile.
a. Some days you drive many miles, and some days you drive fewer miles. Determine the range of daily mileage for which each company is the less expensive choice.
b. Write a report to your boss that includes your recommendations about which car-rental company to use depending on the number of miles you plan to drive. Explain how you arrived at your recommendation. Use computations/written work, graphs, or tables to provide support for your conclusions.
Answer:
A)
If you are driving many miles a day, Alpha Car Rental is cheaper. If you are driving fewer miles a day, then Amazing Car Rental is cheaper.
B)
You can find this out by graphing the 2.
Alpha: y = 0x + 72.
Amazing: y = 0.30x +22.9
Where y is cost, and x is miles.
When you graph the 2, Alpha is a straight line because it has no mileage charge. The 2 linear functions meet at point (163.6, 72). Meaning if you drive more than 163 miles, it is cheaper to use Alpha Car Rental over Amazing Car rental.

Which inequality is true when the value of z is -16
During the msr activity for the month of april, the teacher announced that every student will be awarded 10 points for a good deed and (-5) for not attempting a good deed each day. a) if teena did good deed for all 17 days in april, find her score. b) if tia did not attempt any good deed for 5 days in the same month, find her score
If 10 points are awarded for a good deed and (-5) for not attempting a good deed each day then, a) The score of Teena is equal to 105 b) The score of Tia is equal to 225
a) As Teena did a good deed for 17 days, she would receive 10 points for 17 days, and for the rest of the days, she would be deducted 5 points for each day for not attempting a good deed.
Number of days she did not attempt a good deed = 30 - 17 = 13
Points she got = 17 × 10 = 170
Points for not attempting a good deed = 13(-5) = 65
The final score of Teena can be calculated using subtraction;
Teena score = 170 - 65 = 105
b) If Tia did not attempt any good deed for 5 days this means she did a good deed for 25 days (30 - 5 = 25)
Points she got = 25 × 10 = 250
Points for not attempting a good deed = 5(-5) = -25
Tia score = 250 - 25 = 225
Hence the score of Teena and Tia were calculated to be 105 and 225 respectively.

You have a budget of $300 to order shirts for a math club. The equation. 10x + 12y = 300 models the total cost, where x is the number of short-sleeved shirts and y is the number of long-sleeved shirts.
a. Interpret the terms and coefficients in the equation.
b. Graph the equation. Interpret the intercepts.
c. Find three possible solutions in the context of the problem.
The x-intercept is at point (30,0) and the y-intercept is at point (0,25). The graph of the equation is attached below.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that Short-sleeved shirts cost $10 each.
The Long-sleeved shirts cost $12 each.
The total budget is $300.
The given equation is 10x + 12y = 300
where x is the number of short-sleeved shirts and y is the number of long-sleeved shirts.
We have, 10x + 12y = 300
Substitute the value x = 0
10(0) + 12y = 300
12y = 300
y = 25
So, the y-intercept will be at 0,25).
Substitute y = 0
10x + 12(0) = 300
10x = 300
x = 30
So, the x-intercept is at point (30,0).
The x-intercept is at point (30,0), that means the number of short-sleeved shirts is 30. The y-intercept is at point (0,25), that means the number of long-sleeved shirts is 25.

The mean of the sample means will be 25
As Sample mean is an estimate of the population mean. If we increment the number of observations the precision of the sample means will be improved to get closer to the population mean and according to Central Limit Theorem, The sampling distribution of the sample statistic can be considered roughly if any of the below-mentioned criteria is satisfied :
