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

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.

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.

Li is making beaded necklaces for each necklace, she uses 27 spacers, plus 5 beads per inch of necklace length. Write an equation to find how many beads Li needs for each necklace.
A. Input variable
B. Output variable
C. Equation

Answers

Given that Li is making beaded necklaces for each necklace, she uses 27 spacers, plus 5 beads per inch of necklace length.

The equation to find how many beads Li needs for each necklace can be obtained as follows:

A. The input variable is the number of inches of the necklace length (x).

B. The output variable is the number of beads Li needs for each necklace (y).

C. The required equation is given by

y = 5x
Final answer:

The output variable B (total number of beads needs for each necklace) equals 27 (number of spacers used) plus 5 times the input variable A (length of the necklace in inches). The resulting equation is B = 27 + 5A.

Explanation:

In this question, we're trying to find out the total number of beads Li needs to create each necklace.

Let's define two variables:

A is the input variable, representing the length of the necklace in inches. B is the output variable, which stands for the total number of beads Li needs for each necklace.

Li uses 27 spacers for each necklace regardless of its length and there are 5 beads for every inch of necklace. Given these facts, we can create an equation as follows:

B = 27 + 5A

In this equation, 27 is the number of spacers used, while 5A indicates that 5 beads are strung for each inch of the necklace.

To use this equation, simply replace the variable 'A' with the desired length of the necklace in inches. The result will give the total number of beads Li needs for that particular length of necklace.

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:

0.22 kilometer

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)
