Answer 1
Answer:

Answer:

A

Step-by-step explanation:

To figure out if the table represents the same linear relationship as the equation, you take the x and y values from the table and plug them into the equation. So for table A, I plug in -5 for y and 0 for x, and see if the statement is true. So that turns into -5=(2x0)-5. 2 times 0 is 0, so it is -5=-5. If you keep plugging in for the rest of the numbers for table A, they all fit, therefore A is the right answer.

John is thinking of a number. He gives the following 3 clues. ``My number has 125 as a factor. My number is a multiple of 30. My number is between 800 and 2000.'' What is John's number?Please answer correctly

Answers

Answer:

John's number is 1500

Step-by-step explanation:

* Lets explain how to solve the problem

- Factors of a number are the numbers you multiply to get the number

- Ex: Factors of 12 are 1 × 12 , 2 × 6 , 3 × 4

- The factors of a number smaller than or equal the number

- Multiple of a number is that number multiplied by an integer

- Ex: 2, 4, 6, 8, and 10 are multiples of 2

- The multiples of a number greater than or equal the number

* Lets solve the number

- John is thinking of a number

- He gives the following 3 clues

# The number has 125 as a factor

# The number is a multiple of 30

# The number is between 800 and 2000

∵ 125 is a factor of the number

- Assume that the number is 125 (its factors 1 , 5 , 25 , 125)

∵ The number is a multiple of 30

- Assume the number is 30 (the first multiple of 30)

- To solve the problem lets find the lowest common multiple of 125

  and 30 by using prime numbers only

∵ The prime factors of 125 = 5 × 5 × 5

∵ The prime factors of 30 = 2 × 3 × 5

- L.C.M of the two numbers is the product of their prime factors

 without reputation

∴ L.C.M = 5 × 5 × 5 × 2 × 3 = 750

∵ 750 has 125 as a factor

∵ 750 is a multiple of 30

- But 750 is not between 800 and 2000

∴ Find a multiple of 750 and between 800 and 2000

∵ 2 × 750 = 1500

* lets check the three clues

∵ 1500 has 125 as a factor

∵ 1500 is a multiple of 30

∵ 1500 is between 800 and 2000

∴ John's number is 1500

If you bought a stock last year for a price of $37, and it has gone down 11% since then, how much is the stock worth now, to the nearest cent?

Answers

Answer:

$32.93

Step-by-step explanation:

Stock price has decreased by 11% from $37.

So we need to subtract 11% of 37 FROM 37.

What is 11% of 37?

(11)/(100)*37=4.07

Now we need to SUBTRACT 4.07 from 37.

37 - 4.07 = 32.93

The stock is worth $32.93 now.

If 6 pounds of strawberries cost $11.94 what is the cost of 8 pounds

First find the price of one pound. 11.94÷6=1.99 Once you find the price of 1 pound. You multiply the price of one pound 8 times. 1.99×8=15.92 Hope it helps!

What is 1/2 - 1/6? Please give answer. From Shylalilac!

Answers

First find the same common denominator for both: which is 12. so then it is 6/12 - 2/12 = 4/12 and in the lowest form it is 1/3
it is 1/3 it is like 1/2 of 6 with 1/ before it remember that when subtracting 1/2

The current in a stream moves at a speed of 4 mph. A boat travels 5 miles upstream and 13 miles downstream in a total time of 2 hours. What is the speed of the boat in still water?

Answers

I believe it is 4.5mph because traveling upstream and the stream moves at a speed of 4mph would knock off 4 of the original number so if you add 4miles to the given 5 miles you get 9

The same is with the boat going downstream it is adding 4 miles to the original number so you subtract 13 and 4 and you get 9

If it took 2 hours to do that then you divide 9 by 2 and get 4.5
