Digit 30 stands for minimum strength required after 28 days and 20 stands for maximum size of aggregate
30' x 20' (600 square feet) = 66.6 square yards.
30-20 = 10
It is: 1.5*20 = 30 or 10+20 = 30
"20 out of 30" is 20/30 , which can be simplified to 2/3.
it is a acute angle which represent about 10 mins of a clock
estimate: is 20-30
30' x 20' (600 square feet) = 66.6 square yards.
If there were 30 students in the class, it would mean that 2/5 are girls. Girls = 12. Boys = 18
It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 .
Costs vary by geographic location.
in k-12th grade is about 20 to 30 people in college there is about 300 people
Total score 30 x 75 = 2250, male total 20 x 70 ie 1400, so 10 females scored total of 850, an average of 85.
the strength of concrete
20 percent of 30 = 6 20% of 30 = 20% * 30 = 20%/100% * 30 = 6
The equivalent concrete for M-30 cylinder strength is M-40 cube strength
30-20 = 10
20% off of 30 = 24= 20% discount applied to 30= 30 - (20% * 30)= 30 - (0.20 * 30)= 30 - 6= 24
