1st week of jan, there r 49 dogs and 28 cats in an animal shelter. Throughout the month, the ratio of dogs to cats remain the same. The last week of jan, there are 20 cats in the shelter. How many dogs are there?

Number of dogs in the shelter in the last week is 35

Step-by-step explanation:

Step 1:

Given in the first week of Jan, there are 49 dogs and 28 cats, find the ratio between them.

Ratio = 49/28 = 7/4

Step 2:

Since the ratio remains constant, use it to find the number of dogs in the shelter when cats = 20 in the last week of Jan.

Number of dogs/20 = 7/4

∴ Number of dogs = 20 × 7/4 = 35

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
