A store sells 2 printers for every 5 computers. the store sells 40 computers. how many printers does the store sell?

Answers

Answer 1
Answer:

Answer: 16 printers.

Step-by-step explanation:

We know that every 5 computers sold, the store sells 2 printers.

We know that the store sold 40 computers.

How many groups of 5 computers there are in 40 computers?

there are 40/5 = 8 groups of 5 computers.

So the sotre sold 8 times 2 printers = 8*2 printers = 16 printers
Answer 2
Answer: The store sold 16 printers because 40/5=8, and if they sold 2 printers for every five computers sold, they would have sold 16.

Two numbers have these properties.Both numbers are greater than 8.
Their highest common factor (HCF) is 8.
Their lowest common multiple (LCM) is 80.
Find the two numbers, writing your answers on one line in the form,
The two numbers are ... and ...​

Answers

Answer:

  • 16 and 40

Step-by-step explanation:

Let the numbers be x and y

HCF is 8, so both numbers are multiples of 8 ⇒ x = 8n, y = 8m

As per property of numbers, the product of numbers is equal to product of their LCM and HCF:

  • xy = HCF(x,y) × LCM(x,y)

Since LCM(x,y) = 80 we have:

  • 8×80 = xy
  • 8×80 = 8n×8m
  • 10 = nm

Possible option:

  • n = 2, m = 5

Then the numbers are:

  • x = 2*8= 16
  • y = 5*8 = 40

Johanna purchases a book for $14.95. There is a sales tax of 6.5%. How much is the final price with tax? What is the total? What is the percent? Use the formula amount = total x percent to find the amount of the sales tax. To find the final price, add the cost of the book to the amount of tax.

Answers

Answer:

Tax = $0.97175

Final Price = $15.92175

Step-by-step explanation:

To calculate the amount of tax of an amount you just must multiply this figure by the percentage of the tax expressed in decimal numbers.

-----------------------------------------------------------------------------------------------

Data:

Price = $14.95

Tax rate = 6.5%

-----------------------------------------------------------------------------------------------

Calculation of tax:

amount = total x percent = $14.95 x 6.5% = $14.95 x 0.065 = $0.97175

Calculation of the final price with tax:

Amount = book cost + tax = $14.95 + $0.97175 = $15.92175

-----------------------------------------------------------------------------------------------

Tax = $0.97175

Final Price = $15.92175

-----------------------------------------------------------------------------------------------

Hope this helps!
Okay so 6.5%  of $14.95 is 0.97175. That rounds to 0.97. And to get the total we just add 0.97 to 14.95. Our answer is 15.92. However if you don't want to round then you would add 14.95 and 0.97175 . This would give you15.92175. Hope this helps!
