Total Weight = Weight of the book + Weight of the CD + Weight of the box

Total Weight = 1 1/4 pound + 1/5 pound + 3/10 pound

Total Weight = 5/4 + 1/5 + 3/10

To add these fractions, you need to put them over a common denominator. To do that, find the least common multiple of 4, 5, and 10. Below is a table of the multiples. The least multiple they have in common is 20, shown in orange. So use 20 as your least common denominator.

1 2 3 4 5 6 7

4 x 4 8 12 16 20 24 ...

5 x 5 10 15 20 25 30 ...

10 x 10 20 30 40 50 60 ...

Can you finish it from here?

Precal : Note: Triangle may not be drawn to scale. Suppose a = 3 and A = 15 degrees

Given:

In a right triangle at B,

$\begin{gathered} a=3 \\ A=15^{\circ} \end{gathered}$

To find:

The length of the sides b and c and angle B.

Explanation:

Using the trigonometric ratio,

$\begin{gathered} sinA=\frac{a}{c} \\ \sin15^{\circ}=\frac{3}{c} \\ c=\frac{3}{\sin15^{\circ}} \\ c=11.59 \\ c\approx11.6 \end{gathered}$

Using the trigonometric ratio,

$\begin{gathered} \tan A=\frac{a}{b} \\ \tan15^{\circ}=\frac{3}{b} \\ b=\frac{3}{\tan15^{\circ}} \\ b=11.19 \\ b\approx11.2 \end{gathered}$

Using the angle sum property,

The angle B becomes,

$\begin{gathered} 90+15+B=180 \\ B=180-90-15 \\ B=75^{\circ} \end{gathered}$

Final answer:

The values are,

$\begin{gathered} b=11.2 \\ c=11.6 \\ B=75^{\circ} \end{gathered}$

I got 12 because each time you are dividing the number in half. Half of 24 is 12.
