Note:
sin(-θ) = -sinθ
sin(-15°) = -sin15° Use a calculator
sin(-15°) = -sin15° = -0.2588
sin(-15°) = -0.2588
Perimeter of rec. = 2 ( l + w )
Given: perimeter of rectangle = 322m, length = 86m
Required: width = ?
Solution: 322 = 2 ( 86 + w )
Divide 322 by 2 ie, 322/2 = 86 + w
Will be equal to 161 = 86 + w
Therefore Width= 161 - 86 = 75
I’m pretty sure the answer is 0
Answer:
2184 ways
Step-by-step explanation:
We need to choose exactly one song from each CD, so the number of possible ways to choose a song from a CD is the number of songs in that CD.
The first song is from a CD with 12 songs, so there are 12 possibilities of choosing a song.
The second song is from a CD with 14 songs, so there are 14 possibilities of choosing a song.
The third song is from a CD with 13 songs, so there are 13 possibilities of choosing a song.
Now, to find the number of possible ways to play these songs, we just need to multiply the number of possibilities for each song:
Number of possible ways = 12 * 14 * 13 = 2184 ways
