20 points Amy is moving to college. A cube shaped box holds 27 cubic decimeters
of books. What is the length of each side of the box so she knows what
length books to put in it.
5 decimeters
2.7 decimeters
3 decimeters
9 decimeters

3 decimeters

Step-by-step explanation:

Since this is a cube,

Volume = x^3 [considering x is a one side of the cube]

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
