Answer:
[tex]\frac{6x-4}{x}[/tex]
Step-by-step explanation:
(5 x 6)(3x - 2) = 15xn
30(3x - 2) = 15xn
[tex]\frac{2}{1}[/tex] * (3x - 2) = ([tex]\frac{1}{2}[/tex]xn) * [tex]\frac{2}{1}[/tex]
6x - 4 = xn
n = [tex]\frac{6x-4}{x}[/tex]
You can't cross the 'x' out of the numerator or denominator because of the - 4 in the numerator.

Mandy has a 10.2-ounce container of mustard.
She uses 1/30 of the mustard to put on her hot dog each time.
By given,
Mandy has a 10.2-ounce container of mustard.
Now, 1/30 of the mustard to put on her hot dog each time to 6 hot dogs, so weight of mustard used is calculated as
1/30×6×10.2=2.04 ounces
So, Amount of Mustard left after eating 6 hot dogs is,
10.2-2.04=8.16 ounces
Therefore, the required amount of mustard left after eating 6 hot dogs is 8.16 ounce.

In a scale drawing, 6 inches equals 2 feet. What is the SCALE FACTOR?
Answer:
1 to 4
Step-by-step explanation:
we know 2 feet is equal to 24 inches and 6 inches is .5 feet so 24/6 is 4 meaning that it is 1/4 of the scale factor
Based on the length of the scale drawing and the actual length, the scale factor is 4.
What is the Scale factor?This is a number that multiplies the scale drawing length to find the actual length.
It is found as:
= Actual length / Scale length
Both have to be in the same units so convert the actual length to inches:
= 2 x 12 inches per feet
= 24 inches
Scale factor is:
= 24 / 6
= 4
In conclusion, the scale factor is 4.

Graph All the plans on the graph provided. Your graph should include talk times between 0 and 200 minutes.
2. Was your plan in part B an example of direct variation (the plan depended only on the time spent talking) or a partial variation? (the plan depended on the time spent talking and an initial cost). 3. Which Plan best for you? Was this the same as your hypothesis? 4. Which plan had the highest rate of change? Which plan has the lowest slope?
5. Using your graph, which plan would be best if you talked for 200 minutes? 6. When is the Rogers My5 plan better than the Telus prepaid plan? 7. Which plans are an example of direct variation? 8. Come up with at least 3 other things that need to be considered when choosing your cell phone plan (aside from cost per minute talking), and explain why these are important to you.
I'll do the first five problems to get you started.
==================================================
Problem 1
The graph is shown below in the attached image.
==================================================
Problem 2
The plan chosen was Public Mobile, which offered $24 per month for unlimited minutes. This plan does not depend on the number of minutes, so this is not a direct variation. It's also not a partial variation either since the cost doesn't vary (ie change) at all. The monthly cost is fixed at $24 per month.
Even at 200 minutes, this is the cheapest plan as mentioned in the other chart I posted. You can determine this by plugging x = 200 into each equation described earlier. You should find that Public Mobile still gives the cheapest rate. The graph done in problem 1 visually verifies this. The gray line y = 24 is below each of the other lines when x = 200.
==================================================
Problem 3
The best plan is still Public Mobile when x = 1800 minutes per month.
Any x value such that x > 140 will also have Public Mobile be the best plan.
When we get to x = 140 is when this isn't the best plan and instead Bell is the better plan to go with. Note the purple line y = 0.10x+10 is below the gray line y = 24 for values x < 140. This visually shows us that Bell is cheaper compared to Public Mobile.
==================================================
Problem 4
The plan with the greatest rate of change is Telus. This is because y = 0.35x has the largest slope of 0.35
The rate of change is the charge per minute.
==================================================
Problem 5
If you talked for 200 minutes, then Public Mobile is the best plan. This is because the gray line y = 24 is below any other line when we have x = 200.
What is the volume of a box with sidelines that are 20 inches use the formula B equals S3 where is S is the length of one side
Answer:
The volume of a box with sidelines that are 20 inches is 8000 cubic inches
Step-by-step explanation:
The volume of a box with sidelines that are 20 inches can be determined by using the formula
B = S³
Where S is the length of one side
and B is the Volume
From the question, the sidelines of the box are 20 inches. That is
S = 20 inches
From
B = S³
B = (20 inches)³
B = 20 inches × 20 inches × 20 inches
B = 8000 cubic inches
Hence, the volume of a box with sidelines that are 20 inches is 8000 cubic inches.

In 2000, the world population was 6.1 billion. In 2015, the world population was 7.3 billion. Work out the percentage increase in population. Give your answer correct to 1 decimal place.
Answer:
19.7%
Step-by-step explanation:
Given that,
In 2000, the world population was 6.1 billion.
In 2015, the world population was 7.3 billion.
We need to find the percentage increase in population. The percent increase in this case is given by :
[tex]\%=\dfrac{7.3-6.1}{6.1}\times 100\\\\=19.67\%\\\\=19.7\%[/tex]
So, the increase in population is 19.7%.

On a quiz there are four multiple-choice questions worth 3 points each and two true/talse questions
worth 1 point each. Each multiple-choice question has five possible choices. If a student randomly
guesses on each question, what is the expected value of the student's score on the test?
Using proportions, it is found that the expected value of the student's score on the test is of 3.4 points.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, there are four multiple choice questions, with five options, worth 3 points each, hence the expected score for the multiple choice questions is given by:
Em(X) = 4 x 1/5 x 3 = 12/5 = 2.4.
There are also two true-false questions(two options), worth 1 points, hence the expected score for the two true-false questions is given by:
Etf(X) = 2 x 1/2 x 1 = 1.
Then, the total expected score is given by:
E(X) = Em(X) + Etf(X) = 2.4 + 1 = 3.4.

1) y = 2x + 2
y = -5x + 16
Answer:
y = 6
x = 2
Step-by-step explanation:
rearrange the first equation in terms of x
x = (y - 2)/2
substiute x in the second equation
y = -5[(y-2)/2] +16
Now simpilify and solve for y
y = (-5y + 10)/2 +16
y = -5/2y + 5 + 16
y + 5/2y = 5 + 16
3.5y = 21
y = 6
Now substitue y in the first equation to solve for x

You can use the fact that diagonal of a square are equal and perpendicular to each other.
The option D: Segment BD has a slope of 3 and a length of [tex]2\sqrt{10}[/tex]
Given that:A has coordinate (2,6)B has coordinate (6,8)C has coordinate (8,4)When is ABCD square?One theorem in mathematics states that:
"If diagonals of a quadrilateral are equal and perpendicular to each other, then that quadrilateral is a square."
Using the fact that diagonal of a square are equal and perpendicular to each other:For ABCD to be square, we need AC and BD to be of equal length and perpendicular to each other.
Two lines are perpendicular if their slopes are negative reciprocal of each other.
Slope of AC:[tex]Slope(AC) = \dfrac{rise}{run} = \dfrac{C_y - A_y}{C_x - A_x} = \dfrac{4-6}{8-2} = -\dfrac{1}{3}[/tex]
Thus, slope of BD needed to be negative reciprocal of -1/3 which is 3 for ABCD to be square (first needed condition)
Length of AC:[tex]|AC| = \sqrt{(C_y - A_y)^2 + (C_x - A_x)^2} = \sqrt{(4-8)^2 + (8-6)^2} = \sqrt{2^2 + 6^2} = \sqrt{40} = 2\sqrt{10}[/tex]
The second condition needs |BD| = |AC|.
Thus, length of BC should be [tex]2\sqrt{10}[/tex]
Thus, the sufficient condition for ABCD to be a square is:
Option D: Segment BD has a slope of 3 and a length of [tex]2\sqrt{10}[/tex]

In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°. Find all possible values of ∠V, to the nearest 10th of a degree.
Answer:
The possible values for ∠V is 81.2° and 98.8°
Step-by-step explanation:
In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°. Find all possible values of ∠V, to the nearest 10th of a degree.
We solve the above question using Sine rule
Sine rule
= u/sin U = v/sin V
In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°
Hence:
7.6/sin 68° = 8.1/sin V
Cross Multiply
7.6 × sin V = sin 68° × 8.1
sin V = sin 68° × 8.1/7.6
V = arc sin ( sin 68° × 8.1/7.6)
V = arc sin (0.99)
V = 81.18°
Another value for V = 180° - 81.18°
= 98.82°
Therefore, the possible values for ∠V approximately to the nearest tenth of a degree is 81.2° and 98.8°
