A. 15
B. 90
C. 20
D. 45

Answers

In the question "An animal shelter has a ratio of dogs to cats that's 3:2. If there are 30 cats at the shelter, how many dogs are there" the correct answer is 45 (option D). To solve the problem, let the number of dogs be x, then dogs / cats = 3 / 2 = x / 30. i.e. 2x = 3(30) = 90. x = 90 / 2 = 45. Therefore, there are 45 dogs in the animal shelter.

An animal shelter has a ratio of dogs to cats that's 3:2. If there are 30 cats at the shelter, 45 dogs are there . 3/2 = x/30 , x= 30*3/2 =45

D) 4 square root of 9

Answers

The simplest form of the expression ''7 square root of 3 end root minus 4 square root of 6 end root plus the square root of 48 end root minus the square root of 54'' would be, ''11 square root of 3 end root minus 7 square root of 6''. Hence, option B is true.

Used the concept of the square root of a number that states that,

The square root of a number is the number that, when multiplied by itself, gives the original number.

Given that the expression is,

7 square root of 3 end root minus 4 square root of 6 end root plus the square root of 48 end root minus the square root of 54.

Now, the mathematical form of the expression is,

$7√(3) - 4√(6) + √(48) - √(54)$

Simplify each term,

$7√(3) - 4√(6) +4 √(3) - 3√(6)$

Combine like terms,

$7√(3) +4 √(3) - 4√(6) - 3√(6)$

$11√(3) - 7√(6)$

It can be written as,

11 square root of 3 end root minus 7 square root of 6.

Hence, option B is true.

My question is what is 4-5h how do you solve this problem

Answers

Let us assume that 4 - 5h = 0

we need to the value of h.

4 - 5h = 0
-5h = -4
-5h/-5 = -4/-5
h = 4/5

To check: substitute h by its value.
4 - 5h = 0
4 - 5(4/5) = 0
4 - 20/5 = 0
4 - 4 = 0
0 = 0

Set the expression equal to 0.
4 - 5h = 0

Add 4 on both sides.
5h = 4

Divide by 5 on both sides.
h = $\fbox {4/5}$
