It is called a term. hope it helped
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.
r^2+7=45-r
i think this is the write answer, i havent done that kind of math in awhile.
Answer:
60°
Step-by-step explanation:
Angle CE is equal to angle FD so therefore angle EB must be equal to 60. You obtain this number from subtracting 30 from 90.
