A librarian has 150 books to be placed on shelves with an equal number of books on each shelf. If k is the number of shelves to be used, then 150/k is the number of books on each shelf.

Example : lets say there are 10 shelves.....so k = 10
150/10 = 15 books on each shelf.

Hey

I hope you are having a great day

The answer would be A librarian had 150 books to be placed on shelves with an equal number of books on each shelf. If k is the number of shelves to be used, then 150/k is the number of books on each shelf.

Explanation: Lets see Option 1 is obviously out Option 2 does not make

sense When it comes to option 3 that makes the most sense Option 4 could be right but option 3 is the best and correct answer

So that's your answer

Hope This Helps :)

Three numbers are in an arithmetic progression with a common difference of 6. if 4 is subtracted from the first number, 1 is sub

UkoKoshka [18]

Answer:

either of {-9.5, -3.5, 2.5} or {7, 13, 19}

Step-by-step explanation:

Let x represent the first number of the arithmetic sequence. Then the second number is x+6, and the third number is x+12. The geometric sequence is then ...

(x -4), (x +5), 3(x+9)

The common ratio is then ...

(x +5)/(x -4) = 3(x +9)/(x +5)

Cross-multiplying gives ...

(x +5)² = 3(x -4)(x +9)

x² +10x +25 = 3x² +15x -108 . . . . eliminate parentheses

0 = 2x² +5x -133 . . . . . . . . . . . . . . subtract the left side

0 = (2x +19)(x -7) . . . . . . . . . . . . . . factor

x = -9.5 . . or . . 7

The possible original three numbers are ...

{-9.5, -3.5, 2.5} . . or . . {7, 13, 19}

2. A record store is going out of business and sold any

liubo4ka [24]

Answer:

A) c + CD = 20

B) 6c + 12CD = 192

Multiplying equation A by -6 we get:

A) -6c -6CD = -120

B) 6c + 12 CD = 192

Adding the equations we get

0 + 6 CD = 72

There are 12 CD's and

c + 12 = 20

There are 8 cassettes

What is the probability of getting either blue or green on a spinner that is 3/10 greens and 1/5 blue?

Semmy [17]

Answer:

1/2 or 0.50

Step-by-step explanation:

To find the probability of getting either blue or green on a spinner, we must add both probabilities together.

$\frac{3}{10}+\frac{1}{5} = ?$

To make adding our two fractions easier, we need to make sure they have like denominators.

$\frac{1*2}{5*2} =\frac{2}{10}$

Now that the denominators of our probabilities are the same, we can add them together to get our answer.

$\frac{3}{10} +\frac{2}{10}=\frac{5}{10}$

$\frac{5}{10} =\frac{1}{2}$ or $0.50$
