1 song: 0.99
2 songs: 0.99 + 0.99 = 2 * 0.99
3 songs: 0.99 + 0.99 + 0.99 = 3 * 0.99
...
n songs: 0.99 + .. 0.99 ( n times) = n * 0.99 = 0.99n
Thank you,

Answer:
the slope is 2/3 bcoz u do 2-0/3-0
The net for a triangular prism consists of
2 identical triangles, here all nets have sides 5,12, and 13.
3 rectangles, all with a common dimension: the height H=14 of the prism.
Each of the 3 rectangles should have dimensions
H=14 plus one of the following:
each of 5, 12, 13 corresponding to one side of the base (triangle).
So the dimensions of the rectangles are
5x14, 12x14, 13x14
And dimensions of the triangles are
5,12 and 13.
The total surface area is therefore
(5+12+13)*14 + 2*(5*12/2)
=420+60
=480.
There is only one net that satisfies this condition.
Easy. Okay. We are trying to find out how much of the pizza they both ate together. To do this we need a common denominator. A common denominator of 3/4 and 1/8 are 8. We don't need to convert 1/8 because it already has 8 as the denominator. So we convert 3/4 into a fraction that has a fraction with a denominator of 8. We multiply both the numerator and denominator by 2 which means 3/4 is equal to 6/8. Now all we have to do is 6/8 + 1/8 which we get 7/8. So the answer is 7/8. I hope this helps.
Answer:
k = 3
Step-by-step explanation:
If the line passing through the points A (-1,3k) and B (k , 3) is parallel to the line whose equation is 2y+3x=9, then their slopes are equal
For coordinate AB;
slope m1 = 3 - 3k/k-(-1)
m1 = 3-3k/k+1
For the line 2y+3x = 9
2y = -3x + 9
y = -3/2 x + 9/2
Slope m2 = -3/2
Since m1 = m2
3-3k/k+1 = -3/2
Cross multiply
2(3-3k) = -3(k+1)
Expand
6 - 6k = -3k - 3
-6k+3k = -3 - 6
-3k = -9
k = -9/-3
k = 3
Hence the value of k is 3
