2% of 35,000 is 700. 35,000+700=35,700. The population after the increase would be 35,700.

Just like the other answers, except I will be more specific. So basically, you need to add 2% of 35000 to 35000. So this is the equation you must solve:

35,000 + (2/100 x 35000) = 35000 + 700 = 35700

A shelter has 5 dogs for every 4.cats. How many cats will the shelter have if they have 25 dogs?

olga_2 [115]

Answer:

20 cats

Step-by-step explanation:

A proportion has to be setup to answer this

5/4 = 25/x

x represents the missing number of cats

This fraction represents the relationship amongst dogs and cats

----

To solve cross multiply

5x = 100

(let me down below if you need an explanation on how to cross multiply)

Divide both sides by 5 in order to get the variable by itself

100/5 = 20

x = 20

The shelter has 20 cats

What is the answer for 4y^2=81

Elena L [17]

Answer:
either y = 4.5
or y = -4.5

Explanation:
To get the solution, we will need to isolate the y on one side of the equation.
This can be done as follows:
4y² = 81

 $\frac{4y^2}{4} = \frac{81}{4}$

y² = 20.25

y = +/- √(20.25)
either y = +√(20.25) = 4.5
or y = -√(20.25) = -4.5

Since there are no restrictions on the value of y, therefore, both answers would be accepted

Hope this helps :)
