Answer:
the answer is 19
Step-by-step explanation:
you have to multiply the two numbers
Answer:
1 3/5
Step-by-step explanation:
4/15÷1/6
Copy dot flip
4/15 * 6/1
24/15
Divide the top and bottom by 3
8/5
Change the improper fraction to a mixed number
5 goes into 8 1 time with 3 left over
1 3/5
The area of an equilateral triangle of side "s" is s^2*sqrt(3)/4. So the volume of the slices in your problem is
(x - x^2)^2 * sqrt(3)/4.
Integrating from x = 0 to x = 1, we have
[(1/3)x^3 - (1/2)x^4 + (1/5)x^5]*sqrt(3)/4
= (1/30)*sqrt(3)/4 = sqrt(3)/120 = about 0.0144.
Since this seems quite small, it makes sense to ask what the base area might be...integral from 0 to 1 of (x - x^2) dx = (1/2) - (1/3) = 1/6. Yes, OK, the max height of the triangles occurs where x - x^2 = 1/4, and most of the triangles are quite a bit shorter...
Starts with 5 then adds 6 repeatedly
