Choose two numbers from this list: 3, 4, 6, 12. Explain the difference between finding the greatest common factor and least common multiple of the two numbers.

Answer in at least 2 complete sentences.

Answers

For example let’s pick 6 and 12. To find the greatest common factor, you will break down the number into the numbers you can multiply to get 6 or 12 as much as you can until you reach a prime number.
Now to find the least common multiple, you can set two tables, one of the multiples of 6 and another of the multiples of 12 and see what numbers they have in common and select the smallest number of the multiples they have in common.

Put the following fractions in order from least to greatest, 1/8 2/5, 3/5, 1/6 1/4, 2/3, 1/3

Answers

Answer:

Order from Least to Greatest

1/8 < 1/6 < 1/4 < 1/3 < 2/5 < 3/5 < 2/3

Step-by-step explanation:

A fraction is a way to describe a part of a whole. The given fractions can be arranged as shown below.

What is a Fraction?

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

In order to put the following fractions in order from least to greatest, we need to take the LCM of the fraction so that all the fractions have the same denominator.

1/8, 2/5, 3/5, 1/6, 1/4, 2/3, 1/3

Since the LCM of 3, 4, 5, 6, and 8 is 120. Therefore, the fractions can be written as,

1/8 = (1/8) × (15/15) = 15/120

2/5 = (2/5) × (24/24) = 48/120

3/5 = (3/5) × (24/24) = 72/120

1/4 = (1/4) × (30/30) = 30/120

2/3 = (2/3) × (40/40) = 80/120

1/3 = (1/3) × (40/40) = 40/120

Now, the fractions can be arranged as,

15/120 < 30/120 < 40/120 < 48/120 < 72/120 < 80/120

Rewriting the fraction in there original form,

1/8 < 1/4 < 1/3 < 2/5 < 3/5 < 2/3

Sammy buys his clothes at SuperDuper Discount Store. On Saturday, he bought shoes regularly priced at $40 for 25% off, and a jacket regularly priced at $100 for 30% off. What is the total amount that he will have to pay? (Omit sales tax.)

Answers

you would have 10% chance

Step-by-step explanation:

I know, that's probably a lot to take in! :D

40 × 25% = 10

40 - 10 = 30

The final price of the shoes is $30.

100 × 30% = 30

100 - 30 = 70

The final price of the jacket is $70.

30 + 70 = 100

A N S W E R:

The total price of the items Sammy bought (no including sales tax) is $100.

The Hamptons Family has a fish tank holding 10,450 ml of water. The water is leaking at a rate of 270 ml per minute.

Part A: Define the input and output in the given scenario.


Part B: Write a function to model this situation.


Part C: How many liters of water will be left in the tank after 10 minutes
(hint: liters, not milliliters)

Answers

Answer:

The output would depend on the input so relating this to the question, the input is the time (in minute) and the output is the amount of water left in the tank

We can give a letter 't' for the time, the input, and f(t) for the output

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

The original amount of water in the tank is 10450, so this will be the fixed constant.

The amount of water lost per minute is 270 so this will be the term that varies depends on the variable of time, we write this as 270t

The function is given f(t) = 10450 - 270t

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

Given, t = 10

f(10) = 10450 - 270(10)

f(10) = 7750 ml

Step-by-step explanation:

Answer:

 Part A:

Since the rate of 270 ml per minute has units of ml per minute, then yy must have units of ml and x must have units of minutes. The input must then be the number of minutes the tank is leaking for and the output is the number of ml of water remaining in the tank.

Part B:

Since the tank is leaking 270 ml per minute, then after x minutes, 270x ml of water has leaked out of the tank. The tank initially has 10,450 ml of water so after x minutes, there is y=10,450−270x ml remaining in the tank.

Part C:

After x=10 minutes, the amount of water remaining in the tank is y=10,450−270(10)=10,450−2,700=7,750 ml. There are 1,000 ml in 1 liter so 7,750 ml = 7.75 liters. There are then 7.75 liters of water left in the tank after 10 minutes.
