A train goes from Springfield, MA to Boston at a speed of 40 mph. On the return journey it moves at a speed of 80 mph. If the return journey takes an hour less than the outward journey, what is the average speed overall of the train?
Answer:
The answer is 53.3333333
Step-by-step explanation:
first you know that the speed on the way there is 40 mph and the back is 80
lets call the time x On the way there the time would just be X on the way back it would be x-1 because it took one less our
to calculate the distance you need to do speed times time therefor the distance on the way there would be 40x and the way back would be 80x-80
Then I made an equation 40x=80x-80 X=2
so the distance would be 80 miles but to find average speed you need to do total distance over total time so it would be 160 over 3 because the time is 2x-2 x=2 so thats 3

The graph of F(x) shown below resembles the graph of G(x)=x^3, but it has been changed somewhat. Which of the following could be the equation of F(x)?
Answer && Step-by-step explanation:
We know f(x) transcribes towards -x axis. thus ruling out b and d (remember signs opposite of what they mean on the board, you would think +# =towards x axis and vice versa also note if multiplied by a negative on the outside, flips signs inside)
choosing A.
plug in values of -x to see if you can get ~= to graph so -5 to -1
x: -5, -4, -3, -2, -1
y: -2, -.25, 0, .25, 2
checks out., A is your answer
The equation for f(x) is F(x) = 1/4(x+3)²
Given is a graph, showing the function g(x) = x³, we need to find the equation for the function f(x) in the graph,
We know f(x) transformed towards x-axis.
We see that, there is a left shift of 3 units, so the function will be (x+3)³
Also, the graph is spread out 4 units, so the function can be 1/4(x+3)³
Hence, the equation for f(x) is F(x) = 1/4(x+3)²

Step-by-step explanation:
The measures of the angles in triangle ABC are; m∠A ≈ 73.7°, m∠B ≈ 16.3°, m∠C ≈ 90°
How to find the measures of angles in triangle ABCIt follows that the right angle is between the two shorter sides;
Hence, the angle measure, m∠C ≈ 90°.On this note, the angle, m∠A is opposite side BC;
Therefore, from sine formula;

Sally wants to start a small business. She plans to sell snack packs by re-packing cookies and coffee sachets. Cookies come in packs of 10, while 3-in-1 coffee sachets come in packs of 12.
What is the smallest number of packs for each item should Sally buy if she wants to have packs with 1 cookie and 1 coffee sachet?
Answer: She needs 6 packs of cookies and 5 packs of coffee sachets.
Step-by-step explanation:
Cookies: come in packs of 10
Coffee sachets: come in packs of 12.
Sally wants to sell them in groups of 1 cookie and 1 coffee sachet, then we need to find a common multiple of 10 and 12. (the smallest one in this case).
To find the smallest common multiple, first let's find the largest common factor between 10 and 12.
If we write the numbers as a product of prime numbers, we have:
10 = 2*5
12 = 2*3*3
The only common factor is 2.
Then the smallest common multiple between 10 and 12 is equal to the product of 10 and 12 divided by the largest common factor between them, in this case is 2.
M = 10*12/6 = 60
Now to find the number of packages of each thing that she must buy, we need to divide 60 by the number of elements in each pack.
Cookies: 10 per pack
60/10 = 6
She needs 6 packs of cookies
Coffe: 12 per pack
60/12= 5
She needs 5 packs of coffee sachets.
Hospital administrator Jake Rosen was recently convicted for fraud he committed against his employer, Cedar Hospital Systems. Over a period of six years, Jake allegedly made payments to a dummy company for maintenance charges while simultaneously running a scheme with maintenance contractors where he either paid them for work never performed or overpaid them for work. The skyscraper where Jake worked was only 10 years old. Maintenance charges rose from $5.2 million in 1994 to $16.4 million in 2000. It was worth noting that the judge on the case questioned whether Cedar Hospital Systems deserved less than full restitution for failing to notice the problem. However, it was determined that federal law on restitution does not allow such charges, so Jake Rosen will be making monthly payments toward the alleged $8 million he stole until he makes full restitution after leaving prison. He was able to quickly repay $3.2 million of the theft with assets recovered by the government, including two homes and a nice yacht. Not bad for a man who was supposed to be making $90,000 per year.
1. In what specific types of fraud was Jake Rosen engaged?
2. The judge questioned whether the hospital should be held partially responsible for not having de- tected the fraud. What could the hospital have done to prevent or detect the fraud earlier?
Step-by-step explanation:
Employee frauds are one of most common form of frauds which can be detected in a company. There can be many types or forms of employee frauds.
the major types are:
• Asset Misappropriation
• Bribery and Corruption
• Data theft
• Vendor Fraud
• Payroll Fraud
• Accounting Fraud
2. The hospital could have detected the fraud going on earlier if they had consulted the help of an audit firm this could have helped exposed the fraud earlier.

Step-by-step explanation:
Answer:
x = 2.66 repeating or 2[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
substitute y for x - 5
y = 2x + 3
x - 5 = 2x + 3
subtract 3 from both sides of the equation
x - 5 - 3 = 2x
x - 8 = 2x
subtract x from both sides of the equation
-8 = 2x - x
-8 = -3x
divide both sides of the equation by -3
-8/-3 = x

Explain your answer.
Answer:
I think it would go up on the scale.
Step-by-step explanation:
I believe it would go up, because think about air in your mouth. If you close your mouth and add more air, your mouth gets heavier to carry. Therefore, the air needs to go somewhere. Same with carbonated soft drinks, like soda.

If a family uses 3 gallons of milk every week, how much milk will this family use in four days?
Answer:
Step-by-step explanation:
3 gallons of milk in 1 week means they use 3 gallons of milk in 7 days.
To find out how much milk they use in 1 day, simply divide 3 gallons by 7.
1 day = 3/7 gallons
Then to find how much they use in 4 days, multiply the amount in 1 day by 4.
4 days = 3/7 x 4 = ? Gallons

3x + y = 7
Answer: A C E
Step-by-step explanation:
y = -1x-2 is the perpendicular line of the given line y - 1 = {(x+2).
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The product of slope of perpendicular lines will be equal to minus one.
y-1=x+2 the line has a slope of +1.
The slope of the perpendicular line will be -1.
y = -1x-2 is the perpendicular line of the given line y - 1 = {(x+2).
Hence, y = -1x-2 is the perpendicular line of the given line y - 1 = {(x+2).

Why should we learn the limit definition of the derivative when we could just learn shortcut rules for differentiation?
Answer:
Step-by-step explanation:
I think this is a very essential question to ask. While a lot of people want shortcuts to get things done(i used to too, when I was a student), shortcuts doesn't always cut it short. The reason is just as simple as that of any other subject that deals with theory.
Learning the limit definition gives ample knowledge about how the whole derivation works in general. Yes, quite alright, you can get the basic differentiation done when you don't learn that, but as someone who has gone far in calculus, I'd tell you for free, a time will come during computation where you'd get stuck because you never had that prior knowledge of definition.
Further along the line in calculus, you would be doing derivatives where you'd have to apply your knowledge of the definition of limit, and how would you be able get that done if you hadn't already learnt it?
