If you know that the car travels 0.75 per minute and that there are 60 minutes are in a hour, you could multiply 0.75 with 60, which gives you an answer of 45.
Set up as for portion with X as unknown number of gray cats. So 1/3=x/9. Cross multiply. 3X=9. Divide both sides by 3. X=3.
As shown in the given figure
line a // line b ⇒ given
MR and NP are transversals
So, for ΔMOP and ΔRON , we can conclude the following
(1) ∠1 = ∠2 ⇒⇒⇒ alternative angles are congruent
(2) ∠ MOP = ∠ RON ⇒⇒⇒ vertical angles are congruent
(3) ∠ 4 = ∠ 3 ⇒⇒⇒ alternative angles are congruent
So, from 1,2 and 3
∴ ΔMOP <span>~ </span>ΔRON by AAA-Rule
(1) y = 7x , (2) y = 11x , (3) y = 9x , (4) y = 28x
given y varies directly as x then y = kx ( k is the constant of variation )
(1) find k using the given conditions k = 
= 
= 7
equation is y = 7x
(2) k = 
= 11
equation is y = 11x
(3) k = 
= 9
equation is y = 9x
(4) k = 
= 28
equation is y = 28x
