Answer:
After 5 months each company will charge the same amount
Step-by-step explanation:
Math Modeling
The situation raised in the question can be modeled as follows.
Company A charges $75 upfront (flat or fixed fee) plus $20 a month. Being x the number of months of subscription, the total charge Ca is:
Ca = 75 + 20x
Company B charges no upfront fees, and $35 a month. We model its charges Cb as:
Cb = 35x
We want to know the number of months needed to make both companies charge the same amount. We'll do that by equating Ca=Cb:
75 + 20x = 35x
Subtracting 20x:
75 = 35x - 20x
Swapping and simplifying:
15x = 75
Solving:
x=75 / 15
x=5
After 5 months each company will charge the same amount

During your morning workout, you run for 20 seconds for every 3 seconds you sprint. Determine the constant of proportionality for the ratio between the number of seconds you run and the number of seconds you sprint.
Answer:
Constant of proportionality; k = 20/3
Step-by-step explanation:
Let running be A and sprinting be B.
Now, we are told that you run 20 seconds for every 3 seconds you sprint.
This means that is directly proportional to B and written as; A ∝ B.
Now, constant of proportionality is simply the ratio between 2 quantities that are directly proportional.
Thus, A = kB
Where k is the constant of proportionality
Plugging in the values of A and B we are given, we have;
20 = 3k
Divide both sides by 3 to get;
k = 20/3

What is 60 percent of 92?
O 1.53
0 5.52
O 15.3
0 55.2
60 percent of 92 is 55.2 after applying the concept of the percentage, option (D) 55.2 is correct.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
60 percent of 92
Let x be the 60 percent of the 92
x = 60 % of 92
x = (60/100)92
x = 55.2
Thus, 60 percent of 92 is 55.2 after applying the concept of the percentage, option (D) 55.2 is correct.

In a recent year, the Better Business Bureau settled 75% of complaints they received. (Source: USA Today, March 2, 2009) You have been hired by the Bureau to investigate complaints this year involving computer stores. You plan to select a random sample of complaints to estimate the proportion of complaints the Bureau is able to settle. Assume the population proportion of complaints settled for the computer stores is the 0.75, as mentioned above. Suppose your sample size is 101. What is the probability that the sample proportion will be within 3 percent of the population proportion?
Answer:
0.5137
Step-by-step explanation:
The margin of error equals the critical value times the standard error.
MoE = CV × SE
In this case, the critical value is the z-score.
For a proportion, the standard error is:
SE = √(pq/n)
SE = √(0.75 × 0.25 / 101)
SE = 0.04309
Therefore:
0.03 = z × 0.04309
z = 0.6963
So the probability is:
P(-0.6963 < Z < 0.6963)
= P(Z < 0.6963) − P(Z < -0.6963)
= 0.7569 − 0.2431
= 0.5137

At an end-of-summer clearance sale, Nathan sees a hat marked "65% Off." The original price was $12.98.
Part A
How much money is discounted from the original price? Show your work. Round your answer to the nearest cent.
Answer:
$4.54
Step-by-step explanation:
Because if you take $12.98 and multiply that by 65% you will get 8.437 and when you subtract that by the original amount you will get $4.54.

Please help me with these 2 questions :(
Answer:
1st: y=-2x-3
2nd:y=-2x-13
Step-by-step explanation:
Since the line is parallel to y = -2x-4, its slope is -2. Therefore, we have the equation y=-2x
But when we evaluate that equation at -1, we get -2(-1)=2, but we want to make it equal to -1 when evaluated at -1. Therefore, we can subtract 3, as 2-3=-1.
Therefore, the equation is y=-2x-3.
For the second question, we can use a similar concept. The slope will be -2, but if you directly evaluate it at -4, it's going to be 8, but we want it to be -5, so we subtract 13.
Therefore, the equation is y=-2x-13
Problem 1
Answer: y = -2x-3--------------
Explanation:
Parallel lines have equal slopes but different y intercepts.
Linear equations in the form y = mx+b have slope m and y intercept b.
The slope of y = -2x-4 is m = -2
So any parallel line to this will also have m = -2
Plug (x,y) = (-1,-1) along with the value of m, into y = mx+b and solve for b
y = mx+b
-1 = -2(-1)+b
-1 = 2+b
2+b = -1
b = -1-2
b = -3
The parallel line is y = -2x-3
==============================================
Problem 2
Answer: y = -2x-13--------------
Explanation:
We'll use the same ideas and steps as problem 1.
y = -2x-5 has slope m = -2
The parallel line also has slope m = -2
We want the parallel line to go through (x,y) = (-4,-5)
So,
y = mx+b
-5 = -2(-4)+b
-5 = 8+b
8+b = -5
b = -5-8
b = -13
The parallel line is y = -2x-13
If 3x-y=12, then y/3=?
Answer:
4
Step-by-step explanation:
Answer:
-4
Step-by-step explanation:
To find what y equals, x has to be 0.
3x-y=12
3(0)-y=12
-y=12 (multiply by -1 so y is not negative)
y=-12
Because y=-12 you need to do -12/3 to get your answer to y/3
-12/3=-4
