1) Option C is correct

2) Option B is correct

Step-by-step explanation:

Question no 1:

We need to find the constant of proportionality

The constant of proportionality can be found by using the formula y/x = k, where k is the constant of proportionality.

Finding k:

x = Hot pepper corn

y = chedder corn

So, y/x = 10/4 = 2.5

y/x = 20/8 = 2.5

y/x= 30/12= 2.5

So, Constant of proportionality is k = 2.5

Hence Option C is correct.

Question No 2

Every female rabbit has 5 baby rabbits. We need to find ratio of baby rabbits to female rabbits.

Baby rabbits = 5

female rabbits = 1

Ratio of baby rabbits to female rabbits: 5: 1 or 5/1 = 5

So, ratio of baby rabbits to female rabbits is 5

Option B is correct.

Simplify the following expression completely, where x is greater than or equal too 0.
Dennis_Churaev [7]
First you want the numbers under the radical to be the same so you can combine like terms.

x \sqrt{5xy^4} =x \sqrt{5x*^4y} = xy^2 \sqrt{5x}
\sqrt{405x^3y^4} =  \sqrt{5x*81x^2y^4} =9xy^2 \sqrt{5x}
\sqrt{80x^3y^4} =  \sqrt{5x*16x^2y^4} = 4xy^2 \sqrt{5x}

Now add together to get 14xy^2 \sqrt{5x}

The number of students who passed on the math exam was three-fourths of the total number of students who failed.
Alexxandr [17]

Answer:

one quarter of the total number of students will be those who failed their exam.

Step-by-step explanation:

Three - fourths = those who passed the exam

one quarter will be those who failed their exam

From the total number of the students.

Let's make an example

40 students who take the exam.

3 over 4 students from the total number of 40 take the exam and the result is passed and it mean 30 students passed in the exam.

1 over 4 students take the exam and the result is failed and it mean 10 students failed in the exam.

4 minus 3 over 4 will get the answer 1 over 4.

Use 1 over 4 to multiple with the total number of the students and that how you will get the answer for those who failed in their exam.
