Answer:
Step-by-step explanation:
Percent literally means hundredth
%=p/100 so
p/100=3/10 so multiply each side by 100
p=300/10
p=30%
p/100=2/50 multiply each side by 100
p=200/50
p=4%
So you can see the pattern here, multiply the fraction by one hundred and you have the ‘percentage’.
Just add 360 to -800 until you end up with an angle between 0 and 360:
-800+360=-440
-440+360=-80
-80+360=280
So the angle is 280 degrees.
Answer:

Step-by-step explanation:
To complete the square: add 4 to both sides because the product of 4 as 2 as the factor which 2 * 2 so 



Now we can factor the expression

Move the 4 to the other side to isolate y which changes the sign
It will take about 5.75 days. basicly 5 days and 18 hours.
divide hours by total, and then find out 75 percent of 24
182 games
24 on each shelf
basicaaly
x shelves is more than or equal to 182 games
1 shelf=24
x times 24>182
divide both sides by 24
x>7 and 4/24
x has to be a whole number since you can't have fractional shelves
you have to have more shelves since less shelves won't allow you to carry all of them
round up
7 and something rounded u is 8
8 shelves (if you are a weird store that has fractional shelves then the answer is 7 and 1/6 shelves)
