We need to find 30% of 20 gallons.
1) We can write a proportion
20 gallons ---- 100%
x gallons --------30%
x = 20*30/100 = 6 gallons
2) Or we can write 30% as decimal.
30% = 30/100 = 0.3
0.3 of 20 = 0.3*20 =6 gallons
Answer 6 gallons are used efficiently.
Answer:
x = 1/4
Step-by-step explanation:
remove the parenthesis
collec like terms
caculate
move constant to the right
calculate
divide both sides
~2.09. The formula is (pi)r^2(h)/3 so 3.14286 • 1^2 • 2 is ~6.2857. Divers that by two and get 2.09
Answer:
A. The Number of Lost games = 154 Games
B. Number of games won is greater than the number of games lost.
Step-by-step explanation:
A. how many games did they lose in both years?
Total Number of games = 104 tournaments x 3 Games in each tournament
Total Number of games = 312 Games
The No. of Lost games= Total Games in 2 years - Games won in 1st year - Games won in 2nd year
The No. of Lost games = 312 - 55 - 103
The No. of Lost games = 154 Games
B. Is the number of games won greater than the number of games lost?
Total Number of Games won = 158 Games
Total Number of Games lost = 154 Games
Hence, Total Number of Games won is greater than the Total Number of Games lost.
