The ratio of dogs to cats at an animal shelter is 33 to 22. How many dogs are at the shelter if there is a total of 3030 animals
Elena-2011 [213]
D : c = 33 : 22
where d is the number of dogs and c is the number of cats;
and: d + c = 3030
33 c = 22 d  / : 11
3 c = 2 d
From the other equation: c = 3030 - d
3 * ( 3030 - d ) = 2 d
9090 - 3 d = 2 d
5 d = 9090
d = 9090 : 5
d = 1818
Answer: There are 1818 dogs in the shelter.

30 is 120% of what number? show ur work
Yanka [14]

Answer:

30 is 120% of 25

Step-by-step explanation:

30 = 120% of y

\frac{120}{100} × y = 30

After multiplying both sides by 100 and dividing both sides by 120, we have

y = 30 × \frac{100}{120}

y = 25

Use set builder notation to write each of the following sets 45,55,65,75
butalik [34]

Answer: \{ x: x =5(2n+1) ,4\leq n\leq 7 ,x,n\in N \}

Explanation:

As we know that set is the collection of elements and set builder is the method of defining the set with the help of specific property in which we can use arithmetic operations as well

Generally,

It is the general form of any set in which we can construct the complete set  with the help of equation in the given in set builder form.

Since we have the elements : 45,55,65,75

So, the set builder form will be { x: x =5(2n+1) ,4≤n≤7,x,n∈ N }

We will read it as it is the value of x which will be find with the help of given equation i.e. x=5(2n+1) where n goes from 4 to 7 only and x and n are natural numbers only.
