A rectangular tank will have a square base and its volume will be 125 cubic meters. The cost per square meter for the base is $ 8.00 and for the sides it will be $ 4.00. Find the dimensions of the deposit for the cost of the material is the minimum!

Best answer:
There will be one even number (2) in the sum, then the remaining 1,999,999 primes will be odd (because of they were even they'd have 2 as a factor and not be prime).
The sum of an odd number of odd numbers will be odd. Adding 2 to that will not change the parity, so the final sum will still be odd.

Best answer:
For a complete disc, the surface area is:
s = π.r² → given that the radius is : 2.5 m
s = 6.25 π ← complete disc, i.e. for an angle of 360 °
6.25 π → 360 °
2.63 → x
You make the cross-multiply and you obtain:
6.25 π * x = 2.63 * 360
x = 2.63 * 360 / (6.25 π)
x = 151.488/π
x ≈ 48.22 °

Best answer:
The only thing that matters is the next digit.
I assume you are rounding to the nearest whole number:
4.|495
The only thing that matters is the next digit immediately after the place you are rounding to:
4.|495
....^
If that is *5* or higher, you round up, otherwise you do not. In either case, drop everything...

4.
Another way to think about it:
- Is 4.495 closer to 4 or to 5?
Distance to 4 --> |4.495 - 4| = 0.495 <--
Distance to 5 --> |5 - 4.495| = 0.505
The distance to 4 is smaller, so you would round to 4.
Answer:
4
P.S. Ignore anyone that says consider subsequent digits; they are misinformed.
Two buildings are 35m apart. From the top of the shorter building, the
angle of depression to the base of the other is 47° and the angle of
elevation to the top of it is 21°. Find the height of the taller
building.

Do you mean 2 + 3 = 5...odd
3 + 5 = 8 ..even
5 + 7 = 12... even
2 + 3 + 5 + 7 = 17...odd.
So if you add ALL primes then because of 2 being the only even prime...it will always be odd.
