An animal shelter has 9 puppies. If the puppies are 36% of the total dog and cat population, how many dogs and cats are in the a
Luda [366]

Answer:

Let total number of dog and cat population in animal shelter be x.

As per the statement:

An animal shelter has 9 puppies.

⇒ Total number of puppies = 9

It is also given that if the puppies are 36% of the total dog and cat population.

⇒ 9 = 36\% \text{of}{\text{total number of dogs and Cat}

or

9 = \frac{36}{100} \times x

By cross multiply we get;

900 = 36 x

Divide both sides by 36 we get;

25 = x

Therefore, total number of dogs and cat population in animal shelter are 25

HELPPP!! <br> Triangle ABC is similar to triangle MOP. A = 45 and P = 102. What is the measure of B?
erma4kov [3.2K]

Answer:

       \large\boxed{\large\boxed{33\º}}

Explanation:

The order of the letters naming the triangles is relevant. When it is said that <em>triangle ABC is similar to triangle MOP</em>, means that:

  • ∡A ≅ ∡M
  • ∡B ≅ ∡O
  • ∡C ≅ ∡P

Therefore:

  • ∡A = 45º (given)
  • ∡P = 102º (given)
  • ∡C = 102º (by substitution)

Now, you have two angles of triangle ABC and can find the third one:

  • ∡A + ∡B + ∡C = 180º
  • ∡B = 180º - ∡A - ∡B
  • ∡B = 180º - 45º - 102º = 33º ← answer
