The lowest number is 3.
3 x 588 = 1,764
1,764 = (42) squared
I don't know an easy way to do it. I just slogged through it one-by-one ...
I tried 2 , then I tried 3 and I didn't have to go any farther.
You could have done the same thing. The difference between us is that
I'm willing to work on it just for fun, whereas you're not willing to work on it
even for homework. That's why I became good in math and you might not.
Answer:
Weight of a quarter = 6.25 grams
Weight of a dime = 2.5 grams
Step-by-step explanation:
The weight of a nickel is 80%
The weight of a quarter or the weight of a nickel is 5 grams or weight of a quarter =50.8 = 6.25 grams
Weight of a dime = 50% = 12 (weight of nickel) = 52 = 2.5 grams
Answer:
26 ft square by 13 ft high
Step-by-step explanation:
The tank will have minimum surface area when opposite sides have the same total area as the square bottom. That is, their height is half their width. This makes the tank half a cube. Said cube would have a volume of ...
2·(8788 ft^3) = (26 ft)^3
The square bottom of the tank is 26 ft square, and its height is 13 ft.
_____
<em>Solution using derivatives</em>
If x is the side length of the square bottom, the height is 8788/x^2 and the area is ...
x^2 + 4x(8788/x^2) = x^2 +35152/x
The derivative of this is zero when area is minimized:
2x -35152/x^2 = 0
x^3 = 17576 = 26^3 . . . . . multiply by x^2/2, add 17576
x = 26
_____
As the attached graph shows, a graphing calculator can also provide the solution.
