kelly has 4times as many songs on her music playlist as lou . tiffany has 6 times s many songs on her playlist as lou . altogeth
Dmitriy789 [7]
Hello! To answer this question we have to make an equation. In this equation I will represent the total number of songs Lou has as the variable x. 

So 4x +6x + x = 682

This simplifies to 11x = 682. When you divide both sides by 11 you get x = 62.  This is how many songs Lou has. 

Since we are trying to find how many songs Kelly has, we must multiple 62 x 4 to get 248. Kelly has 248 songs.

The information given represents lengths of sides of a right triangle with c the hypotenuse. Find the correct missing length to
Alenkasestr [34]
<span>So we need to find the lenght of side a of a right triangle if we know b=13 and c=21 and c is the hypotenuse and we need to round the number to the nearest hundreth. So we can do that with Pythagorean theorem which states that: a^2 + b^2 = c^2. Now we simply put b^2 to the right side and find a^2 as: a^2=c^2 - b^2. Lets plug in the numbers and we will get a= sqrt (21^2 - 12^2)=16.492422. When we round it to the nearest hundreth a= 16.49.</span>
