PLEASE HELP NOBODY EVER ANSWERS MY QUESTIONS Rip van Winkle has fallen asleep for a very long time.

UNO [17]

Answer:

10 millimeters

Step-by-step explanation:

Don't listen to the other answerer who was trolling, I will actually help you. To find how long his beard was when he fell asleep, we need to find the y-intercept. The y-intercept marks how long his beard was right when he fell asleep. From looking at the graph, we can see that the y-intercept is 10. This means his beard was 10 millimeters long when he fell asleep. I hope this helps!

Serena asked her parents if for their picnic they could have 20% more portions of coca-cola than they planned, and if each porti

jeyben [28]

Answer:

44%

Step-by-step explanation:

If p represents the number of portions and q represents the quantity in each portion, then the original amount needed was p·q.

After p is increased by 20%, its number is ...

p + 0.20·p = 1.20·p

After q is increased by 20%, its amount is ...

q + 0.20 ·q = 1.20·q

Then the new amount the parents must buy is ...

(1.20p)(1.20q) = 1.20²·pq = 1.44pq

This amount is ...

(1 + 44/100)·pq = pq + 44%·pq

It is 44% more than the original planned purchase.

A possible domain could be (0,1,2,3...)

If n is the number (not the value) of quarters received, then n cannot take values which are fractions and n cannot take negative values. Its values have to be non-negative integers. (Note that 0 is possible.)

Ratling [72]

Step-by-step explanation:

If it cost $1200 to install 100 square feet of roofing, then it will cost $13200 to have 1100 square feet installed.

$1200/ 100 square feet multiply 11 on both sides

$13200/ 1100 square feet
