Answer: $600
Step-by-step explanation:
Given that you're trying to round to the nearest tens, you should look at the ones place, in this case 4. Given that 4 is less than 5, and anything less than 5 rounds down, you should round down to $600 instead of $610.
Hope this helps!
Answer:
1/5
Step-by-step explanation:
divide each side by 5
5x/5=1/5
simplify
x/5=1/5
He has about 28 fiction books. Since 312 divided by 11 is equal to <span>28.3636363636, you can't have a decimal number for the amount of books, so you round down to 28. </span>
Answer:
2000.8 m or 2km height
(π 0.07^2)×2000 = 30.78 m^3.
Step-by-step explanation:
The total surface area of a cylinder of radius 7 cm is 880 m^2. Find the height and the volume of the cylinder.
"A cylinder is flat" according to curvature theory (unlike a sphere, where triangle angles can add to more than 180°). So unwrap it and compute area as circumference times height, or height as area divided by circumference. 880m^2 / (2 π 0.07 m) gives height = 2000.8 m or 2km (!!)
The volume of a cylinder is cross section area times height. (π 0.07^2)×2000m = 30.78 m^3.
