Let the side of the square base be x, and the height of the box be h.
<span>The material of the base is x^2, and the material of the four sides is 4xh. </span>
<span>4000 = hx^2 </span>
<span>h = 4000/x^2 </span>
<span>The total material is </span>
<span>M = x^2 + 4x(4000/x^2) = x^2 + 16000/x </span>
<span>Take the first derivative of M and set equal to 0. </span>
<span>M' = 2x - 16000/x^2 = 0 </span>
<span>Multiply by x^2: </span>
<span>2x^3 = 16000 </span>
<span>x^3 = 8000 </span>
<span>x = 20; h = 10; M = 1200</span>
Answer:I think it’s B
Step-by-step explanation:
<u>Answer:
</u>
The number of students who did not attend the career seminar in decimal form is approximately equal to 0.06 students.
<u>Solution:
</u>
It is given that 88 out of 94 students are attending a career seminar. We have to find out in decimal form how many students did not attend the career seminar
The number of students who did not attend the career seminar is given by = (94 - 88) students.
Therefore number of students who did not attend the career seminar = 6 students.
It means 6 out of 94 students did not attend the career seminar.
In decimal form it can be represented as
= 0.06 students
The prime numbers between 40 and 50 are:
41
43
47
