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.
30
estimate: is 20-30
30' x 20' (600 square feet) = 66.6 square yards.
Class sizes at Florida State University can vary, but on average there are about 20-30 students in an undergraduate class and 15-20 students in a graduate class.
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 .
Stamped concrete is generally more expensive than regular concrete because it requires additional labor, coloring, texturing, and sealing. On average, regular concrete costs about $5–$10 per square foot, while stamped concrete typically ranges from $8–$19 per square foot, depending on the design complexity and finish. While stamped concrete has a higher upfront cost, it offers a decorative, high-end appearance that can mimic stone, brick, or slate and may enhance curb appeal.

Costs vary by geographic location.
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 number of people in a class can vary and depends on the specific class size set by the school or institution. Typically, a class can range from around 20 to 30 students in primary and secondary education, while in higher education settings like colleges or universities, class sizes may be larger and can vary depending on the course or program.
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
