Answer:
125 dogs and cats
Step-by-step explanation:
35 puppies make up 28% of the total dog and cat population
so 28% of the total population is 35
let x = the total population
0.28x = 35
x = 35 / 0.28
x = 125 <=== total dogs and cats

Half way is 440/2 = 220. Subtract the 66 miles already traveled, and they have 154 miles to go.
Answer:

Step-by-step explanation:
Given
tan a = 
= 
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h = 
= 41 , thus
sin a = 
= 
cos a = 
=
