Answer: The side of the square will be 3 cm.
Step-by-step explanation:
When squares of equal size of side x, are cut from the four corners, we are left with the following dimensions for the cuboid box.
l= 30-2x
b = 14-2x
h= x
Hence, the volume of the cuboid will be ,
V = lbh
= (30-2x)(14-2x)x
Since this volume should be the largest possible, then differentiating volume with x should be equal to zero.
Therefore, 
solving we get, x = 3, x = 
We can omit x = because 14 - 2x < 0 , which is not possible.
Therefore, x=3.
Answer:
She spent 2 and a half hours doing extra work.
Answer:
y=-0.5x+4
Step-by-step explanation:
x intercept=-0.5/1
y intercept=4
The answer is A
since 2x+3(2x)=16
Hence 8x=16
Answer:
0.6628 or 66.28%
Step-by-step explanation:
The probability that a randomly selected dropout is white, given that he or she is 16 to 17 years old is determined by the probability of them being a white 16 to 17 years old dropout (5.7%), divided by the probability of them being a 16 to 17 years old dropout of any ethnicity (8.6%):
There is a 0.6628 or 66.28% chance that a randomly selected dropout is white, given that he or she is 16 to 17 years old.
