Answer:
go to 100
56 is 56 percent of 100
28 is 56 percent of 50
Step-by-step explanation:
Answer:
500
Step-by-step explanation:
It's a box with a square base, so let's say the width and length are x and the height is y.
The surface area of the box without the top is:
A = x² + 4xy
300 = x² + 4xy
The volume of the box is:
V = x²y
Solve for y in the first equation and substitute into the second:
y = (300 − x²) / 4x
V = x² (300 − x²) / 4x
V = x (300 − x²) / 4
V = 75x − ¼ x³
To optimize V, find dV/dx and set to 0:
dV/dx = 75 − ¾ x²
0 = 75 − ¾ x²
x = 10
So the volume of the box is:
V = 75x − ¼ x³
V = 500
The maximum volume is 500 cm³.

Answer:
3 I believe
Step-by-step explanation:
so AB is equal to BC. AC is equal to CD. AD is 12 in total and if you half it it is 6. AC is half of AD. Therefore I got 3
The answer would be B. Let's say Katrina's father was 10 inches tall. Subtract 2 inches to measure Katrina's mother's height, subtract another 2 inches to measure Katrina's height. Finally, subtract another 2 inches to measure Katrina's brother's height. Add all the negative 2s together in order to get -6. That is the difference between Katrina's father's height and her brother's height.
