All except the third, because when you distribute the three you get 15w+24 that is equivalent to -3(-5w-8).

USPshnik [31]

Answer:

There are 60 monkeys in the Zoo

Step-by-step explanation:

In this question, we are asked to calculate the number of monkeys in a Zoo given some information to use.

Let’s have the total number of monkeys be m.

60% are going monkeys. This means number of young monkeys is 0.6m.

The number of baby and old monkeys is obviously 0.4m.

Ratio of baby to old monkeys is 3:1. This means if we splitter 0.4m into 4, number of baby monkeys is 0.3m while number of old monkeys is 0.1m

Now, subtracting the number of baby monkeys from young monkeys give a total of 18 monkeys.

Let’s project this mathematically;

This means ;

0.6m - 0.3m = 18

0.3m = 18

m = 18/0.3

m = 60

Find the value of x. Round your answer to the nearest tenth sin x degree= 4/15

bulgar [2K]

Answer:

The value of x to the nearest tenth is, 15.5 degree

Step-by-step explanation:

Given that: $\Sin x = \frac{4}{15}$

To find the value of x;

Take inverse of sin both sides we have;

$\sin^{-1}(\sin x) = \sin^{-1}(\frac{4}{15})$

Simplify:

$x = \sin^{-1}(\frac{4}{15})$

Simplify:

$x = 15.46601015^{\circ}$

Therefore, the value of x to the nearest tenth is, 15.5 degree
