The answer is 320.
If 16 = x / 20, then x = 320
Multiply both sides of the equation by 20:
20 * 16 = 20 * x / 20
Multiply the terms on the left side of the equation:
320 = 20x/20
320 = 20/20 * x
Simplify the rigth side of the equation:
320 = 1 * x
320 = x
Therefore, x = 320
Answer:
44%
Step-by-step explanation:
185/420 = 0.4405
0.4405 * 100 = 44.05%
378 divided by 6 is 63
That is the solution. 63 is the final answer. You could mix it around to make sure and say... 6 times 63 equals 378
But there is no more than 63
1/5 because there are 7 numbers divisible by 5 from 1 to 35. 5,10, 15, 20,25,30,35, and out of those there are 35 cards, 7 out of 35 or 7/5 can be simplified to 1/5.
Check the picture below. Recall, is an open-top box, so, the top is not part of the surface area, of the 300 cm². Also, recall, the base is a square, thus, length = width = x.

so.. that'd be the V(x) for such box, now, where is the maximum point at?

now, let's check if it's a maximum point at 10, by doing a first-derivative test on it. Check the second picture below.
so, the volume will then be at
