Two cars leave town going in opposite directions. one car is traveling 55 miles per hour (mph), and the other car is traveling 40 mph. how long will it take before the cars are 285 miles apart?

Answers

The distance, d, traveled by a car going at speed, s, in time, t, is
d = st

Car 1 travels distance 1, d1, at s1 = 55 mph, for t1 time.
Car 2 travels distance 2, d2, at s2 = 40 mph, for t2 time.

The two distances add to 285 miles, so
d1 + d2 = 285
The two times are equal, so t1 = t2 = t

d1 = 55t1
d2 = 40t2

d1 = 55t
d2 = 40t

d1 + d2 = 55t + 40t

d = 95t

285 = 95t

95t = 285

t = 3

Answer: It will take 3 hours.

Note:
This problem shows you that if two cars are traveling along the same line in opposite directions, the speed at which they are distancing themselves is the sum of the two speeds. We can solve the problem in a simpler way:

55 mph + 40 mph = 95 mph

d = st

285 = 95t

t = 3

Answer: 3 hours.

If a certain number is added to both the numerator and denominator of the fraction 7 6 76, the result is 3 2 32 . find the number.

Answers

Assuming that the right statement is that if a certain number is added to both the numerator and the numerator of the fraction 7/6, the result is 3/2, find the number, the solution if found in this way:

Call x the number (certain number)

=> (7+x) / (6 +x ) = 3/2

=> (7 + x)*2 = 3*(6 + x)

=> 14 + 2x = 18 + 3x

=> 14 - 18 = 3x - 2x

=> - 4 = x

verification> ( 7 - 4) / ( 6 - 4) = 3 / 2

Answer: the number is - 4.

1. round the result to 2 decimal places. -0.9x+2.8=4.1
a) -2.56
b) -2.56
c) -1.44

Answers

1. -0.9x+2.8=4.1
First subtract 2.8 from both sides.
-0.9x = 1.3
Now divide both sides by -0.9.
x = -1.4444..
This can be rounded to -1.44
c) -1.44

2. Jordan has 650 pennies. He'll give 85 to his brother and split the rest with his sister.

The sum of two numbers is 67 . the larger number is 5 more than the smaller number. what are the numbers?

Answers

Call the numbers x and y. According to the first sentence, x + y = 67. According to the second sentence, x = y + 5. You can combine these two equations to find the values of these variables:

x + y = 67
(y + 5) + y= 67
2y = 62
y = 31

You can use this to find x by plugging in y to either original equation:

x = y + 5
x = 31 + 5
x = 36

Answers

It seems like there are only two problems here. Problem 1 is the one with Maddie throwing the baseball. Problem 2 deals with the cyclist. For some reason you threw in "What is the height of the ramp, to the nearest foot?" in the middle of the baseball problem. That seems like a typo?

======================================================
Problem 1 (baseball problem with Maddie)

a = 90
b = 90
c = unknown

Pythagorean Theorem
a^2+b^2 = c^2
90^2+90^2 = c^2
8100+8100 = c^2
16200 = c^2
c^2 = 16200
sqrt(c^2) = sqrt(16200)
c = 127.279220613579

If we round to the nearest ten, then we get 130. In other words, 127.279 is closer to 130 than it is to 120.

So it looks like "130 feet" (choice B) is the final answer.
======================================================
Problem 2 (cyclist on a hill problem)

sin(angle) = opposite/hypotenuse

A share of stock in the Lofty Cheese Company is quoted at 251/4. Suppose you hold 30 shares of that stock, which you bought at 201/4. If you sell your stock at 251/4, how much profit do you get or lose?

Answers

You'll make a profit of $150.

To calculate the profit from buying and selling stocks, subtract the buying price per share from the selling price per share and then multiply by the number of shares. For 30 shares of the Lofty Cheese Company stock, the profit would total $150.

The question involves calculating the profit from buying and selling stocks. When selling the Lofty Cheese Company stock quoted at 251/4 per share, we need to calculate the profit based on the purchase price (201/4) and the selling price (251/4) for 30 shares.

To find the profit per share, subtract the buying price from the selling price:

Selling Price per Share = 251/4

Buying Price per Share = 201/4

Profit per Share = Selling Price - Buying Price = 251/4 - 201/4 = 5

Then, multiply the profit per share by the total number of shares:

Number of Shares = 30

Total Profit = Profit per Share times Number of Shares = 5 times 30 = 150

Therefore, you would realize a total profit of $150 by selling your 30 shares of the Lofty Cheese Company stock.

Justin is constructing a line through point Q that is perpendicular to line n. He has already constructed the arcs shown. He places his compass on point B to construct an arc. What must be true about the width of the compass opening when Justin draws the arc?
A .It must be wider than when he constructed the arc centered at point A.

B It must be the same as when he constructed the arc centered at point A.

C. It must be equal to BQ .

D.It must be equal to AB .

Answers

B. It must be the same as when he constructed the arc centered at point A. This problem would be a lot easier if you had actually supplied the diagram with the "arcs shown". But thankfully, with a few assumptions, the solution can be determined. Usually when constructing a perpendicular to a line through a specified point, you first use a compass centered on the point to strike a couple of arcs on the line on both sides of the point, so that you define two points that are equal distance from the desired intersection point for the perpendicular. Then you increase the radius of the compass and using that setting, construct an arc above the line passing through the area that the perpendicular will go. And you repeat that using the same compass settings on the second arc constructed. This will define a point such that you'll create two right triangles that are reflections of each other. With that in mind, let's look closely at your problem to deduce the information that's missing. "... places his compass on point B ..." Since he's not placing the compass on point Q, that would imply that the two points on the line have already been constructed and that point B is one of those 2 points. So let's look at the available choices and see what makes sense. A .It must be wider than when he constructed the arc centered at point A. Not good. Since this implies that the arc centered on point A has been constructed, then it's a safe assumption that points A and B are the two points defined by the initial pair of arcs constructed that intersect the line and are centered around point Q. If that's the case, then the arc centered around point B must match exactly the setting used for the arc centered on point A. So this is the wrong answer. B It must be the same as when he constructed the arc centered at point A. Perfect! Look at the description of creating a perpendicular at the top of this answer. This is the correct answer. C. It must be equal to BQ. Nope. If this were the case, the newly created arc would simply pass through point Q and never intersect the arc centered on point A. So it's wrong. D.It must be equal to AB. Sorta. The setting here would work IF that's also the setting used for the arc centered on A. But that's not guaranteed in the description above and as such, this is wrong.
