What is the Least Common Multiple of 12 and 18? Please explain how you got your answer!

Elenna [48]

Least common multiplue is the smallest number that the 2 numbers can multiply into so exg LCM of 3 and 2 is 6,
to find, find the factors
12=2 times 2 times 3
18=2 timeds 3 times 3
so combine all of them
in 12, we have 2 2's and 1 three
in 18, we have 1 2 and 2 3's so
we must have 2 2's and 2 3's so
2 times 2 times 3 times 3=36=lcm\
so find factors and group

lcm=36

Pleaseee help I keep getting undefined

Answer:

Second option "B. 4" is the correct choice.

Step-by-step explanation:

$(-8)^{\frac{2}{3}}\\\\\mathrm{Apply\:exponent\:rule}:\quad \left(-a\right)^{\frac{m}{n}}=\left(-1\right)^{\frac{m}{n}}\left(a\right)^{\frac{m}{n}}\\\\=\left(-1\right)^{\frac{2}{3}}\cdot \:8^{\frac{2}{3}}\\\\=1\cdot \:8^{\frac{2}{3}}\\\\=8^{\frac{2}{3}}\\\\=\left(2^3\right)^{\frac{2}{3}}=2^{3\cdot \frac{2}{3}}=2^2\\\\=4$

Best Regards!

Use the law of Sines to find the missing angle of the triangle. <br> Find m

Whitepunk [10]

Ah...Trigonometry is fun!

The law of sines states:
$\frac{sinA}{a}= \frac{sinB}{b} = \frac{sinC}{c}$
The transitive property (switching the orders of the equations) applies here. Therfore, we can say that $\frac{sinA}{a}=\frac{sinC}{c}$

We then plug in our given values to find C

$\frac{sin24}{77}=\frac{sinC}{162}$
$\frac{162*sin24}{77}=sinC$
Solving, we get 0.8557316387. We're not done yet!

We are trying to find an angle measure, so we'll do the inverse of the ratio we used (sin).

arcsin0.8557316387 (arcsin is the same as inverse sin)
=58.8 (approximate)

So the measure of angle C is 58.8. You could check this by reinserting it into the equation $\frac{sinA}{a}= \frac{sinB}{b} = \frac{sinC}{c}$ .
