Answer:
h=30cm
Base sides, x=30cm
Step-by-step explanation:
Let x be the dimension of the sides and h the dimension of height;
#Material used is directly proportional to surface area. Minimizing surface area will minimize the amount of material used.
Find area as a function of x:
To minimize Area, we find the first derivative of Area:
#find the second derivative to verify the minimum:
Substitute x in the volume equation to find h:
Hence, the dimensions of the box that minimize the amount of material used h=30cm and x=30cm
Answer:
A=45.5B= 7 inches therefore: 45.5/7= 6.5height is 6.5.
Step-by-step explanation:
Answer:
Y= x+2
Step-by-step explanation:
The x value is always adding 2 to get the y value
1+2=3
2+2=4
3+2=5
4+2=6
5+2=7
Therefore your answer is y = x + 2

To decrease 64 by 60%
Working Out:
60%/100% = 0.6
0.6 x 64 = 38.4
Therefore to decrease by 60%
64 - 38.4 = 25.6

Answer:
a) 100000 feet
b) 1000000 feet
c) 10^5 and 10^6
Step-by-step explanation:
a) to find area, the formula is length x width
therefore, you would calculate 1000 x 100.
b) to find volume, the formula is length x width x height
therefore you would calculate, 1000 x 100 x 10.
c) look at the amount of zeros for each number and you will find your answer.
Hope this helps!!
