HELP ASAP!! Write the inverse variation function given that y varies inversely with x, and y = 2 when x = 8.

Answers

Answer 1
Answer: So, the equation for inverse variation is y=k/x.

So we replace x and y with the numbers given in the problem statement.

2=k/8

Then we

Reggie ate 31 raisins. Which correctly describes 31 as a prime or a composite number and tells the number of factor pairs 31 has? You're choices are: A-31 is a prime number because it has 0 factor pairs. B-31 is a prime because it has 1 factor pair. C-31 is a composite number because it has 1 factor pair. D-31 is a composite number because it has 2 factor pairs.

Answer:

?????

Step-by-step explanation:

??????

Final answer:

The number 31 is a prime number and has exactly one factor pair which is 1 and the number itself, so the correct answer is option B.

Explanation:

The value 31 is considered a prime number.

A prime number is a number that only two distinct positive divisors: 1 and itself. Therefore, every prime number has exactly one factor pair, which is 1 and the number itself.

So, option B-31 is a prime because it has 1 factor pair is the correct answer. This means that the factors of 31 are simply 1 and 31.

so the correct answer is option B.

What is the next value 1I 2L 3F4

Answers

Answer:

The next value in the given pattern of digits and numbers is:

                      E

Step-by-step explanation:

  • Since, if we see the first pair:

                   1 I

Then we see that the alphabet I requires just one vertical line to get formed.

  •  The next pair is:

                    2 L

Hence, from this we could claim that L is formed with the help of one vertical and one horizontal line.

  •   The next pair is:

                   3 F

Again the alphabet F could be formed with the help of 3 lines one vertical and two horizontal line.

  • Hence, from the above three pairs we may infer that the next pair will be:

                   4 E

because E is formed with the help of four lines 1 vertical and three horizontal lines.

Final answer:

The next term in the sequence is 4U.

Explanation:

The given sequence seems to follow a pattern where the 1st term is the number itself, and the 2nd term is the last letter of the number. The 3rd term is the 1st letter of the next number, and so on.

  1. 1I
  2. 2L
  3. 3F
  4. 4U

Therefore, the next term in the sequence would be 4U.

Jillian is selling boxes of cookies to raise money for her basketball team. The 10 oz. box costs $3.50, while the 16 oz. box costs $5.00. At the end of one week, she collected $97.50, selling a total of 24 boxes. The system of equations that models her sales is below. x+ y= 24 3.50x + 5.00y = 97.50 Solve the system of equations. How many 10 oz. boxes were sold? a. 6
b. 9
c. 12
d. 15

Answers

we have to solve simultaneous equations.
                                                                     
x = 10 oz. boxes
                                                                     
y = 16 oz. boxes
                                                                               
simultaneous equations
                                                                     
x + y = 24 ---1)
                                                                     
3.50x + 5.00y = 97.50 ----2)
                                                                   
to solve for x we need to eliminate y, therefore we have to multiply 1st equation by 5
                                                                   
5x + 5y = 120 --3)
                                                                   
subtract 3) - 2)
                                                                   
5x - 3.50x = 120 - 97.50
                                                                   
1.50x = 22.5 x = 15

If bc = 8.3 cd = 6.7 and ad = 11.6 find ab to the nearest tenth

Answers

This is going to be tricky to explain over text, so try to bear with me :)

You have the information given above. Let's start with just ad = 11.6 for now. since these are variables, it can also be understood be understood as a times d= 11.6. 
Knowing this, we can figure out that d = 11.6/a, when you divide both sides by a.

You now have d, so plug (11.6/a) into cd=6.7. You have to do the same thing you did last time, except this time you are aiming to get c by itself. So, multiply both sides by a/11.6 and you get c = (6.7a)/ 11.6. 

Guess what, you know c now! so you put (6.7a)/11.6 in for c in the equation given to you earlier, bc =8.3. The math gets a bit messy here, but you basically solve for b here, which, when you crunch the numbers down, ends up being ~14.3705 divided by a. You are looking for ab, so just multiply both sides by a, and round to the nearest tenth so that you have ab= 14.4
