Answer:
the answer is the first one. i just did it and double checked
Step-by-step explanation:
The volume of a pyramid is expressed as the product of its length, width and height divided by three. We first solve the volume of pyramids A and B.
Volume of A = (10 x 20 x h) / 3 = 200h / 3
Volume of B = (10 x 10 x h) / 3 = 100h/3
Since the heights of the two pyramid are the same we can substitute on equation to the other in terms of h.
Volume of A = (200 x 3 x Volume of B) / (100 x 3)
Volume of A = 2 x Volume B
Thus, the volume of A is twice the volume of B.
If the height of pyramid B is twice of pyramid A, the new volume of pyramid B is equal to the volume of pyramid A.
Since there is 1000 millimeters in a meter, all you would do is divide 585 by 1000. The quotient of that is .585. So the sandwich would be .585 meters.
I hope this helps you somehow

Answer:
7 years
Step-by-step explanation:
The multiplier each quarter is 1 +10%/4 = 1.025. The number of quarters, n, that must pass before the value is multiplied by 2 is given by ...
1.025^n = 2
Taking logarithms, we can solve for n:
n×log(1.025) = log(2)
n = log(2)/log(1.025) ≈ 28.071
It will take 28 quarters, or 7 years, for the value to double.
