50 POINTS<br>what is 2^-4×r^3×s^-2 <br>when r=-3 and s=5?<br>Explain please..

Korvikt [17]

You'll get -6.25
To find a negative power, put it 1 over it and remove the negative symbol. For example, to simplify 2^-4, we would do 1/2^-4, then remove the negative to get 1/2^4, which is 0.0625
Then you have that -3^3 is -27 (since -3*-3*-3 is -27). Then using the above method, you can simplify 5^-2 to 1/5^2, which is 0.4

0.0625*-27*0.4 is -27/400

Alinara [238K]

Answer: The number of kittens= 500.

Step-by-step explanation:

Given, A random sample of cats at the SPCA shows that 25 out of the 40 cats are kittens.

i.e. ratio of kitten to cats = $\dfrac{25}{40}=\dfrac{5}{8}$

We assume that , the ratio will remains same.

Let x be the number of kitten out of 800 , then we have

$\dfrac{x}{800}=\dfrac{5}{8}\\\\\Rightarrow\ x=\dfrac{800\times5}{8}=500$

Hence, the number of kittens out of 800 cats= 500.
