Answer:

7,500

Step-by-step explanation:

Let's solve this problem step-by-step. The library had 1,500 books in 2011. The ratio of books in 2011 and in 2012 is 1:2. Therefore, let the number of books in 2012 be x.

We have the following proportion:

\frac{1}{1,500}=\frac{2}{x},\\x=2\cdot 1,500=3,000

Therefore, there were 3,000 books in 2012. The ratio of books in 2012 and in 2013 is 2:5. Let the number of books in 2013 be y.

We have:

\frac{2}{3,000}=\frac{5}{y},\\2y=5\cdot 3,000,\\2y=15,000\\y=\boxed{7,500}

Therefore, there were 7,500 books in 2013.

Trinity created a game that uses a card number 1 to 8 and a six sided cube numbered 1 to 6. Each player chooses one card and roa
Ksju [112]

Answer:

Correct option: A -> 1/24

Step-by-step explanation:

To find the probability of having a card with the value greater than six, the options are: 7 and 8. So there are two options in the total of 8, so the probability is P1 = 2 / 8 = 1/4

The cube has 6 numbers, from 1 to 6, so the probability of rolling a six is P2 = 1/6

To find the final probability, we multiply both probabilities, so:

P = P1 * P2 = (1/4) * (1/6) = 1/24

Correct option: A

You have two spinners
dem82 [27]

Answer:

There is a \frac{1}{12} chance of the spinner landing on red, then three.

Step-by-step explanation:

So the first one has a \frac{1}{4} chance, since there are four possibilities.

The second one has a \frac{1}{3} chance, since there are three possibilities.

So, we just need to combine them.

\frac{1}{4} *\frac{1}{3} =\frac{1}{12}

Have a nice day. Please mark brainliest!
