Find the prime factorization of each value.

21 is 7*3

30 is 3*10 which can be further broken down into 3*2*5

44 is 4*11 which can be further broken down into 2*2*11

What do they share in common?
21 and 30 each have a 3 in common.
Therefore the GCF(21, 30) = 3.

21 and 44 share a 2 in common.
But if we're looking at all three of them together, they share nothing in common.

Andrew [12]

Answer:

1.75 gallons of paint

Step-by-step explanation:

A student in the construction trades program has 4 1/2 gallons of paint

If the student uses 2.75 gallons in one room then the gallons of paint that are left can be calculated as follows

= 4 1/2 - 2.75

= 9/2 - 2.75

= 4.5 - 2.75

= 1.75

Hence 1.75 gallons of paint are left

I need it right now please help me!
tankabanditka [31]

I can't directly tell you the answer, but I can help you for how to do it.

So every single time you want to find the rate of change (slope) label 2 points with x1, y1, x2 and y2. We can use the point-slope form to sind the slope:

y1-y2/x1-x2

And we just need to plug in the point to get the Y intercept.

When the x is 0, the y value will be the y-intercept.

The slope intercept form is: y=Mx+B. M stands for slope and B stand for y-intercept. Just plug the slope and y-intercept in and get the answer.

Use the term demand and quantity demanded correctly in a sentence about concert tickets.
Afina-wow [57]

Answer:

"The demand was so high for the concert tickets that the concert manager posted a tweet on social media saying that the quantity they had, wasn't enough for the amount of people that wanted to buy concert tickets."

Step-by-step explanation:

Quantity in economics is the amount in total of the product there is.

Demand in economics is how much the consumer is willing to buy the product that is being sold.

A sentence using the two words quantity and demand about concert tickets would look something like this: "The demand was so high for the concert tickets, that the concert manager posted a tweet on social media saying that the quantity they had, wasn't enough for the amount of people that wanted to buy some of the concert tickets."

Hope this helps.
