Answer:
Step-by-step explanation:
x-5/2<-5
divide x-5 by 2
1/2x-2.5<-5
factor out the -2.5 by adding it to both sides
1/2x< -2.5
divide both sides by 1/2
x=-1.25

A line passes through the points(-8,-7) and (-4, -4) what is the equation of the line in slope intercept form
Answers
Step-by-step explanation:
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y + 7)/(-4 + 7) = (x + 8)/(-4 + 8)
(y + 7)/3 = (x + 8)/4
4(y + 7) = 3(x + 8)
4y + 28 = 3x + 24
4y = 3x + 24 - 28
4y = 3x - 4
y = 3x/4 - 1

Answers
Answer:
2203/1000
Step-by-step explanation:
Answer:
2.203
Step-by-step explanation:
Subtract 7/10 from both sides of the equation
2.903 = [tex]y[/tex] + 7/10
2.903 - 7/10 = y + 7/10 - 7/10
SimplifySubtract the numbers
2.903 - 7/10 = y + 7/10 -7/10
2.903 = y + 7/10 - 7/10
Subtract the numbers
2.903 = y + 7/10 - 7/10
2.903 = y
Move the variable to the left
2.903 = y
y = 2.903

Marketing Addis prepares marketing plans for growing businesses. For 2017, budgeted revenues are $1,500,000 based on 500 marketing plans at an average rate per plan of $3,000. The company would like to achieve a margin of safety percentage of at least 45%. The company’s current fixed costs are $400,000 and variable costs average $2,000 per marketing plan. Which of the following changes would help Marketing Docs achieve its desired margin of safety? a) The average revenue per customer increases to $4,000. b) The planned number of marketing plans prepared increases by 5%. c) Marketing Addis purchases new software that results in a 5% increase to fixed costs but reduces variable costs by 10% per marketing plan.
Answers
Answer:
1. Break even points = 400 units
margin of safety = $100
Explanation:
Given data:
budget revenue in 2017 = $1,500,000
Fixed cost =$400,000
total marketing plan = 500
take contribution margin/unit = Revenue - variable cost
= 3000 - 2000
contribution margin/unit = $1000
take break even sales $400
break even point
Break even point
margin of safety is calculated as
margin of safety = total quantity to be sold - break even sales
= 500 - 400 = $100
2. A.
(1)
Break even in marketing plan = 400
(2) Break-even in dollars:
= Break-even in marketing plan × Average rate per plan
= 400 × 3,000
= 1,200,000
(3) Margin of safety = Actual sales - Break-even sales in dollars
= 1,500,000 - 1,200,000
= 300,000
= 20%
B.
(1) Contribution margin per marketing plan = Sales - Variable cost
= $4,000 - $2,000
= $2,000
Break even in marketing plan = 200
(2) Break-even in dollars:
= Break-even in marketing plan × Average rate per plan
= 200 × 4,000
= 800,000
(3) Margin of safety = Actual sales - Break-even sales in dollars
= 1,500,000 - 800,000
= 700,000
= 47%
Therefore, option (a) would achieve the margin of safety ratio more than 45%.

blue: 36.4 mpgred: 29.5 mpgblue goes farther on 1 gallonStep-by-step explanation:
You find miles per gallon by dividing miles by gallons. ("Per" essentially means "divided by.")
blue(45.5 mi)/(1.25 gal) = 36.4 mpg
red(23.6 mi)/(0.8 gal) = 29.5 mpg
__
"Miles per gallon" is the number of miles traveled on one gallon. The blue car can travel a greater distance on 1 gallon of gasoline.

Dakota paid $301.32 for a new game system, after tax, and the tax rate is 8%. What was the original price of the game system?
Answers
Answer: 279.
Step-by-step explanation:
First, change the percentage to a decimal and write the equivalence of the sales tax amount. Let x be the original cost of the item.
Sales tax amount =x⋅0.08
Next, substitute the value into the equation:
Original Cost + Sales Tax Amount = Total Cost
x+0.08x=301.32
Add like terms.
1.08x=301.32
Divide both sides by 1.08 to isolate the unknown value.
x=$279

You have been gotten a job offer and the company wants to start you out at
$45,000 and will give you a 5% raise every year. Write an equation you could use to
determine how much you would be making after x number of years.
Answers
The equation that we would be making after x number of years is S(x) = 45000(1.05)^x where S(x) is the salary in xth year since the year of joining the job.
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
Let the initial income be P
Let the raise be of R% annually.
Then, after 1 year, it would become
[tex]P_1 = P + (R\% \: of \: P) =P + \dfrac{P}{100} \times R = P\left(1 + \dfrac{R}{100}\right)[/tex]
Now, after 1 more year(second year), we get:
[tex]P_2 = P_1\left(1 + \dfrac{R}{100}\right) = P\left(1 + \dfrac{R}{100}\right)\left(1 + \dfrac{R}{100}\right) = P\left(1 + \dfrac{R}{100}\right)^2[/tex]
After one more year(third year), we get:
[tex]P_3 = P_2\left(1 + \dfrac{R}{100}\right) = P_1\left(1 + \dfrac{R}{100}\right)^2 = P\left(1 + \dfrac{R}{100}\right)^3[/tex]
Similarly, on xth year, we get:
[tex]P_x = P\left(1 + \dfrac{R}{100}\right)^x[/tex]
This is the salary on xth year.
For this case, we're provided that:
P = $45,000R = 5Thus, we get:
[tex]P_x = P\left(1 + \dfrac{R}{100}\right)^x\\\\P_x = 45000(1 + 0.05)^x = 45000(1.05)^x = S(x) \: \rm (say)[/tex]
Thus, the equation that we would be making after x number of years is [tex]S(x) = 45000(1.05)^x[/tex] where S(x) is the salary in xth year since the year of joining the job.

Acrylic bone cement is sometimes used in hip and knee replacements to secure an artificial joint in place. The force required to break an acrylic bone cement bond was measured for seven specimens, and the resulting mean and standard deviation were 306.07 newtons and 41.96 newtons, respectively. Assuming that it is reasonable to believe that breaking force has a distribution that is approximately normal, use a 95% confidence interval to estimate the mean breaking force for acrylic bone cement. (Round your answers to three decimal places.)
Answers
The required 95% confidence interval for the mean breaking force of acrylic bone cement is approximately 267.29 to 344.85 newtons.
Find the critical value (t*) for a 95% confidence level and (n - 1) degrees of freedom.
The degrees of freedom (df) is equal to the sample size minus 1 (df = 7 - 1 = 6). From a t-table or statistical software, the critical value for a 95% confidence level and df = 6 is approximately 2.447.
Calculate the standard error of the mean (SE).
The standard error of the mean is given by SE = (sample standard deviation) / sqrt(sample size).
[tex]SE =\dfrac{41.96}{\sqrt{7}}[/tex]
≈ 15.85
Calculate the margin of error (MoE).
The margin of error is MoE = (t*) * SE.
MoE ≈ 2.447 * 15.85
≈ 38.78
Calculate the confidence interval.
The confidence interval is given by: Mean ± MoE.
Mean ± MoE ≈ 306.07 ± 38.78
Calculate the lower and upper bounds of the confidence interval.
Lower bound ≈ 306.07 - 38.78
= 267.29
Upper bound ≈ 306.07 + 38.78
= 344.85
Therefore, the 95% confidence interval for the mean breaking force of acrylic bone cement is approximately 267.29 to 344.85 newtons.

Figure A and figure B are similar right triangles.
Which series of transformations could have been applied to Figure A to create Figure B?
A dilated 150% then reflected across the x-axis
B dilated 250% then reflected across the y-axis
C dilated 250% then rotated 270 degrees clockwise about the origin
D dilated 500% then rotated 90 degrees counterclockwise about the origin
Answers
Answer:
Step-by-step explanation:
The legs of A seem to be about 2 and slightly less than 2 units in length.
The legs of B seem to be about 4.5 and 4.5 units in length
4.5/2 = 2.25 or 225% increase so NONE OF THE ABOVE answer is correct.
If we ASSUME that the legs of B are supposed to reach 5 and 5 (they don't) or the legs of A are both supposed to be 1.8 (hard to say, certainly the bottom one seems to exceed that)
then the dilation would be 5 / 2 = 2.50 or 250%
Which means we have an option of B) or C) to choose from
Reflecting A across the y axis would put B in the first quadrant so NO.
Rotating A 270° CW about the origin would give us B in the third quadrant which is correct.
So the CLOSEST answer is option C) (dilation not with standing)

A car can drive 415 miles on 10 gallons of gasoline. What is the car’s mileage for 1 gallon of gas?
Answers
Answer:
41.5
Step-by-step explanation:
Answer:
41.5 miles per gallon
Step-by-step explanation:
Since you are finding the miles per gallon, you should do 415 and 10 both divided by 10 to find the number of miles for one gallon. 415 divided by 10 is 41.5, while 10 divided by 10 is 1, so for one gallon, the car can drive 41.5 miles, or 41.5 miles per gallon.
