If you would like to know the volume of the classroom, you can calculate this using the following steps:
30 feet long * 30 feet wide * 10 feet high = 30 * 30 * 10 = 9000 ft^3
The correct result would be 9000 ft^3.
Answer:
A
Step-by-step explanation:
8 gallons of regular gas with 10% and 2 gallons with 85%
8 x 10 =80%
2 x 85 =170%
170+80=250%
10 gallons each with 100%, so 10 x 100 =1000%
250% of 1000% = 1/4 or 25% ethanol
Hope this helps!
just divide 20 by coefficient of x
x < 20/2
x < 10
