Answer:

65 non-fiction books need to be shelved

Step-by-step explanation:

This question can be solved using a rule of three.

For each 5 non-fiction books, there are 9 fiction books. How many non-fiction books are there when there are 117 fiction books?

5 non-fiction - 9 fiction

x non-fiction - 117 fiction

$9x = 5*117$

$x = \frac{5*117}{9}$

$x = 65$

Consider a pattern that begins with 9 and each consecutive number is twice the previous term. What are the first four terms of t

ahrayia [7]

"Twice the previous term" means the previous term is multiplied by 2 to get the present term. In other words, the next term is 2 times the present term.

The first term is 9 (given).

The second term is 2×9 = 18.

The third term is 2×18 = 36.

You can figure the 4th term, but there is no need. This is sufficient to identify the correct answer as ...

... D. 9, 18, 36, 72

You are making cookies for a party. The ratio of Cookie Tray A to Cookie Tray B to Cookie Tray C is 2 : 3 : 4. If you need to ma

Elenna [48]

Given that the ratio of three trays is A : B : C = 2 : 3 : 4

Let us consider the common factor among the number of trays be "x".

If we need to make a total of 171 trays, then the equation of sum of trays would be :-

Type A + Type B + Type C = 171

2x + 3x + 4x = 171

9x = 171

x = $\frac{171}{9}$ = 19

So we have following number of trays :-

Number of type A trays = 2x = 38 trays.

Number of type B trays = 3x = 57 trays.

Number of type C trays = 4x = 76 trays.

Now if each tray contains 20 cookies, then we would have following arrangements :-

Cookies in type A trays = 38×20 = 760 cookies.

Cookies in type B trays = 57×20 = 1140 cookies.

Cookies in type C trays = 76×20 = 1520 cookies.
