Hope this helped :)
Answer:
5in by 5in by 5in
Step-by-step explanation:
We are not told wat to find but we can as well find the dimension of the prism that will minimize its surface area.
Given
Volume = 125in³
Formula
V = w²h ..... 1
S = 2w²+4wh ..... 2
w is the side length of the square base
h is the height of the prism
125 = w²h
h = 125/w² ..... 3
Substitute eqn 3 into 2 as shown
S = 2w²+4wh
S = 2w²+4w(125/w²)
S = 2w²+500/w
To minimize the surface area, dS/dw = 0
dS/dw =4w-500/w²
0= 4w-500/w²
Multiply through by w²
0 = 4w³-500
-4w³ = -500
w³ = 500/4
w³ =125
w = cuberoot(125)
w = 5in
Get the height
125 =w²h
125 = 25h
h = 125/25
h = 5in
Hence the dimension of the prism is 5in by 5in by 5in
Answer:
I think the answer is 42
Step-by-step explanation:
So, with all of that, the equation will now be = 5^2 + (2 * 8) / 2 + (3 * 3)
So next, you can use PEMDAS. After that, u should get ur answer of 42.
Work:
5^2 + (2 * 8) / 2 + (3 * 3)
5^2 + 16 / 2 + 9
25 + 16 / 2 + 9
25 + 8 + 9
25 + 17
= 42
Hope this helps :D!!
Answer:
c
Step-by-step explanation:
OK 250 divided by 40 equals 6.25 so she would need 6 bags at least, i would say its your answer but you said its wrong so
