Mary sees 40 elephants and 15 baby elephants at the zoo. What is the ratio of elephants to baby elephants?

40:15 = 8:3

Step-by-step explanation:

This is the answer because:

1) Since there are 40 elephants and 15 baby elephants, the answer would be 40:15, but we want to simplify the ratio. In order to simplify the ratio, just divide each number by 5:

40 ÷ 5 = 8

15 ÷ 5 = 3

8:3

Therefore, the answer is 8:3.

Hope this helps! :D

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
