5/12-3/20 use the least common multiple as the denominator

Answers

Answer 1

Answer: The common multiple of 12 and 20 is 60.
You've got to multiply the first one by 5 and the second by 3.
5*5= 25
This therefore becomes 25/60
The second becomes 3*3= 9
This becomes 9/60
As you're subtracting, you only subtract the numerators.
25-9= 16
Therefore, the answer is 16/60 which can be simplified to 4/10 or 2/5
Hope this helps :)

An employee is to mark up a piece of jewelry 120%. If a necklace costs $100, what should its selling price be?

Answers

$220

The employee has to mark up the $100 piece of jewelry by 120%. This means that the employee must add 120% of 100 to the original price of the jewelery. To find this, we simply multiply, since "of" in math means multiplication.

So, we must calculate 120% • 100 = 120 (because 120% = 1.2 and 1.2 • 100 = 120)

Now, we just add: 100 + 120 = 220, so the selling price should be 220

Arif and keisha go to a restaurant fot dinner. their meals total $13.75 and the tax is 5%Question: Arif and keisha want to leave a 15% tip based on the bill and tax combined. how much should they leave? Explain.

Answers

The total cost of the dinner meals taken by Arif and Keisha = $13.75
Percentage of tax that need to be given = 5%
Then
Amount of tax that needs to be given = (5/100) * 13.75 dollars
   = 13.75/20 dollars
   = 0.687 dollars
   = 0.69 dollars
So
The total amount that needs to be
paid for dinner including tax = (13.75 + 0.69) dollars
   = 14.44 dollars
Percentage of tips that they both want to leave = 15%
Then
Amount of tips that need to be given = (15/100) * 14.44
   = 216.6/100 dollars
   = 2.17 dollars
So
The total amount that they should leave = (14.44 + 2.17) dollars
   = 16.61 dollars
So they should leave a total of $16.61 in the restaurant.

How do I use inductive reasoning to predict the next three numbers in the pattern 9,11,13,15,17How do I predict this next three numbers in the pattern 9,11,13,15,17_ _ _

Answers

You inspect the series that you have, very carefully.

-- You notice that 9 was increased by 2 to get 11.
-- You notice that 11 was increased by 2 to get 13.
-- You notice that 13 was increased by 2 to get 15.
-- You notice that 15 was increased by 2 to get 17.

By now, it begins to dawn on you. You say to yourself "Self ! I'll just bet
that each term has to be increased by 2 in order to get the next term."

Acting on that assumption, you set out on your flight of prediction:

-- You take the last term, 17, increase it by 2,and get 19.

-- You take the new term that you have created, 19,
increase it by 2, and get 21.

-- You take the 2nd new term that you have created, 21,
increase it by 2, and get 23.

Now you have the three new terms, and that's all you were asked for.
But you're just getting warmed up. Nothing can stop you now.

25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49,
51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75,
77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99, 101

Suddenly, you stop ! You just realized that this is not the ONLY
possible pattern that would produce the same first 5 numbers.

Realize that each bumber goes up by 2 more. So you are looking at the relationships between the numbers
