Answer:
Part A)
Part B)
Step-by-step explanation:
Part A)
Let
----> length song
----> length song
----> length song
----> length song
----> length song
-----> break between each song
we know that
The length of the CD is equal to
substitute the values
Part B)
Subtract the total length of the CD from minutes of music
so
Well, if the integer is negative it would be positive, if it was positive it would be negative.
Negative x Positive = Negative
Negative x Negative = Positive
Answer:
no
Step-by-step explanation:
We must find the volume of a box with:
• square base with diagonal ,h = 6 cm,,
,
• height ,H = 15 cm,.
1) First we compute the length of the sides of the square base.
From the diagram above, we see that the diagonal of the box constitutes the hypotenuse of a triangle of sides a. Pitagoras Theorem states that the square of the hypotenuse is equal to the sum of the squares of the other sides, so we have:
Replacing the value h = 6 cm, and solving for a², we get:
2) The volume is given by the product of height (H) and the area of the base (a²):
Answer
The volume of the box is 270 cm³.
