When dividing two fractions, we turn the second fraction upside-down and multiply two expressions instead.
[tex] \frac{5}{6} \times \frac{ - 3}{2} = \frac{ - 15}{12} [/tex]
Now simplify the fraction by dividing it with biggest common divisor which is 3 in this case.
[tex] \frac{ - 5}{4} [/tex]
is the final result.
Suppose your cable company charges its customers $4 to rent a movie. An online membership costs $21 and members pay only $2.50 to rent a movie. For what number of movies is the cost the same?
The number of movies that will give same cost is 14 movies.
How to calculate the number of movies?From the information, the cable company charges its customers $4 to rent a movie and an online membership costs $21 and members pay only $2.50 to rent a movie.
Let the number of movies for same cost be represented by x. This will be:
(4 × x) = 21 + (2.50x)
4x = 21 + 2.50x
Collect like terms
4x - 2.50x = 21
1.50x = 21
Divide
x = 21/1.5
x = 14
The number of movies will be 14

Solve 6(x+3) < 3(2x+6)
Answer:
No solutions.
Step-by-step explanation:
Pre-Solving GivenWe are given the inequality 6(x+3) < 3(2x+6), and we want to solve the inequality for x.
SolvingWe can first do the distributive property on both sides, where we multiply each term on the left side by 6, and each term on the right by 3.
6(x+3) < 3(2x+6)
6x + 18 < 6x + 18
Solving inequalities is a lot like solving equations; we want to isolate the variable by itself on one side.
First, we can subtract 18 from both sides.
6x + 18 < 6x + 18
-18 -18
____________________
6x < 6x
Now, we can subtract 6x from both sides, to get 6x off the right side.
6x < 6x
-6x -6x
0 < 0
We now have the inequality 0 < 0. This is never true, as 0 is always equal to 0.
Therefore, there are no values of x that will make this true, because no matter what, we will end up with a false statement. The answer is no solutions.
ms. wilson draws a model of the factorization of a polynomial with integer factors. her model is partially complete. which equation is represented by ms. wilson’s model? n2 3n 40
n²+13n+40,
This is why;
Observe only the right side. The number is (n+8)(n+5).
Let's elaborate on that using FOIL.
F = When we multiply the first two terms, n and n, we obtain n².
O = outer instructs us to multiply n by 5 to get n*5 or 5n from the outer terms.
I = inner instructs us to multiply the inner expressions 8 by 8 and n by n to obtain 8n.
Since 8 and 5 are multiplied by L, we obtain 8*5 = 40.
Add up the outcomes: n²+5n+8n+40 = n²+13n+40
Observe how the phrase is a little bit simplified by the combination of the like terms (5n and 8n).
This demonstrates how (n+8)(n+5) becomes n²+13n+40, becoming the correct response. For all values of n, none of the other options are valid equations;

Given the following, what is the length, l?
V = lwh
V = 576, w = 6, h = 12
The value of l is. We use simple substitution of values to find the value of l is 48.
We have been given the equation V=lwh where l is the length, we can say that the given equation is that of volume of a cuboid where l is the length, w is the width and h is the height of the cuboid. We know the values of V,w and h. We have to substitute the values of V,w and h in the equation V=lwh inorder to find the value of l. Substitution method is generally used for solving system of equations where we first solve the value of one variable and then substitute the value in the other equation to find the value of the other variable. Since we only have one equation and we know the value of 3 of the 4 variables we only have to solve for one.
V=lwh
l=V/wh =[tex]\frac{576}{6.12} =\frac{576}{72}[/tex]= 48
Thus we get the value of l to be 48 by substituting the values of V,w and h.

Part A: Which of the following design is most appropriate: observational study, experiment, census, or sample survey? Explain your reasoning.
Part B: Explain how you would implement the design you selected in Part A.
Part C: Explain one benefit your design would provide.
The most appropriate design is an experiment (A), this can be applied by having a control and an experimental group (B), and one benefit is that you can identify the effectiveness (C).
Why is the best design an experiment?Different from an observational study, a census or a survey that are used to collect information about people's preferences, an experiment allows you to test the effectiveness of a treatment, which is the main purpose in this case.
How to implement it?The bst is to have a control and an experiment group. For example you select 30 dogs and use the repelant in 15 dogs; then all dogs are exposed to ticks. As a result you can evaluate how effective the repelant is by comparing the two groups.

SHIPPING The U.S. Department of Commerce regulates how much the actual weight of a package can vary from its labeled weight. A package with a labeled weight of 9.4 pounds can have an actual weight that is plus or minus 0.22 pound.
Part A
Write an absolute value equation to represent the maximum and minimum acceptable weights of the package. Let x be the actual weight of the package.
The simplified value of the maximum weight is 9.62 and the minimum weight is 9.18. Also the function for the maximum and minimum weight is y + x and y - x
Here,
Given that, A package with a labeled weight of 9.4 pounds can have an actual weight plus or minus 0.22 pounds.
Let the weight labeled be y and the actual weight be x
Weight = y ± x
Maximum weight = y + x
Minimum weight = y - x
Weight = 9.4 ± 0.22
Now,
Maximum weight = 9.4 + 0.22 = 9.62 pounds
Minimum weight = 9.4 - 0.22 = 9.18 pounds
Thus, the simplified value of the maximum weight is 9.62 and the minimum weight is 9.18. Also, the function for the maximum and minimum weight is y + x and y - x

A men’s median weekly earning with Bachelor’s degree only is $1,384 * 4 weeks = $5,536
A women’s medium weekly earning with a Bachelor’s degree only is $1,041 * 4 weeks = $4,164
Subtract $5,536 - $4,164 = $1,372
The full sentences are:
The typical monthly salary for women with bachelor's degrees is $3,020.
The typical annual salary for a guy with an associate's degree is $36,432.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
Every month has four weeks.
The median monthly income is thus:
Earnings = 4 * $755
Earnings = $3020
As a result, the typical monthly salary for women with bachelor's degrees is $3,020.
The median annual income:
A man with an associate's degree makes $759 each week.
A month has four weeks, while a year has twelve months.
Hence, the annual median income is:
Earnings = 4 x 12 x $759
