Answer 1

Answer:

The answer is $19.44

Step-by-step explanation:

First, set up a proportion for tax and tip.

Your proportion should be x (the variable) over 28.80, equal to 25 over 100.

Then, cross multiply to set up an equation.

Your equation should be 100x is equal to 720.

Solve the equation by dividing both sides by 100, getting the amount for your variable, x, which should be $7.20.

Next, subtract $7.20 from the original price of 28.80, getting $21.60.

Next, set up the same proportion, except make it so that x is over $21.60 and 10 is over 100.

Cross multiply and set up your equation which is 100x is equal to 216.

Solve the equation by dividing both sides by 100, getting the value if x as $2.16.

Finally, subtract $2.16 from the sale price of $21.60, giving you your answer of $19.44.

13. The process by which sperm is made is called Sertoli cells.

14. The process by which eggs are made is called oogenesis.

15. During the creation of an oocyte, 3 additional haploids are created that will not be fertilized these cells are called Polar bodies.

Answer:

C

Step-by-step explanation:

Let's see if this makes sense and applies to all of the pairs.

1. y will be 2

x will be 6

2=1/3(6)

1/3 times 6 is 2.

2. y will be 1

x will be 3

1=1/3(3)

1/3 times 3 is 1.

3. y will be 0

x will be 0

0=1/3(0)

1/3 times 0 is 0.

4. y will be -1

x will be -3

-1=1/3(-3)

1/3 times -3 is -1.

They all apply to C meaning that C is the right answer.

1) A. y= 3x

2)B.

D.

Answers

Answer:

B. 300

60 · 5 = 300

Answer:

300 students

Step-by-step explanation:

So just to summarize the question we know that 20% of students = 60 students. and we know that there are five 20 percents in 100% if that makes sense the example below explains it much clearer:

 1          2         3          4        5

20% + 20% + 20% + 20% + 20% = 100%

So to figure out how many students are in 100% we have to multiply it by 5 since there are 5 20 percents in 100%

So 60 students times 5 = 300

So, in conclusion, 300 students ate breakfast.
