We have:
Song 1 = 3 1/10 minutes
Song 2 = 4 2/3 minutes
Minutes of memory of two songs:
![3\frac{1}{10}+4\frac{2}{3}=\frac{31}{10}+\frac{14}{3}=\frac{3\times31+10\times14}{30}=\frac{93+140}{30}=\frac{233}{30}=7\frac{23}{30}](https://tex.z-dn.net/?f=3%5Cfrac%7B1%7D%7B10%7D%2B4%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7B31%7D%7B10%7D%2B%5Cfrac%7B14%7D%7B3%7D%3D%5Cfrac%7B3%5Ctimes31%2B10%5Ctimes14%7D%7B30%7D%3D%5Cfrac%7B93%2B140%7D%7B30%7D%3D%5Cfrac%7B233%7D%7B30%7D%3D7%5Cfrac%7B23%7D%7B30%7D)
Answer:
The roses were 20 dollars :) have a good day.
<span>A cube is a geometric three-dimensional solid object. It constitutes
6 square faces, sides and three meeting at each vertex. It is the only regular
hexahedron. A cube has a fixed number of
perpendicular angles. Typically, it has 8 perpendicular angles and each spigolo
or corner has 3 angles. Since it has 8 perpendicular (⊥) angles and 3 angles in
each corner, it makes up 24 angles.
All 8 ⊥ angles and 3 angles in each corner mean: 8*3=24.
Therefore, a cube has 24 right angles.</span>
