Answer:
1/8
Step-by-step explanation:
Leonard spent 1 fourth of his money on a sandwich.
Fraction of money spent on sandwich = 1/4
He spent 2 times as much on a gift for his brother as on some comic books.
= 1/4 × 2
= 2/8
Hence, Fraction of money spent on Comic books = 2/8
He had 3 over 8 of his money left.
Let us represent his total money has: 1
The fraction of his money that he spent on the comic books is calculated as:
= 1 -( 1/4 + 2/8+ 3/8)
Lowest Common Denominator = 8
= 1 - (2 +2 + 3/8)
= 1- 7/8
= 1/8
Therefore, the fraction of his money that he spent on the comic books is 1/8
Start with #47. To find the critical values, you must differentiate this function. x times (4-x)^3 is a product, so use the product rule. The derivative comes out to f '(x) = x*3*(4-x)^2*(-1) + (4-x)^3*1 = (4-x)^2 [-3x + 4-x]
Factoring this, f '(x) = (4-x)^2 [-3x+4-x]
Set this derivative equal to zero (0) and solve for the "critical values," which are the roots of f '(x) = (4-x)^2 [-3x+4-x]. (4-x)^2=0 produces the "cv" x=4.
[-3x+ (4-x)] = 0 produces the "cv" x=1. Thus, the "cv" are {4,1}.
Evaluate the given function at x: {4,1}. For example, if x=1, f(1)=(1)(4-1)^3, or 2^3, or 8. Thus, one of the extreme values is (1,8).
Answer:
Answer: 704
Step-by-step explanation:
Volume of cuboid- 80x44x25=88000 cm cube
volume of each 5cm cubes= 5x5x5=125 cm cube
Therefore 88000/125=704.
