Mathematics

(a + b)^{3}  =  {a}^{3}  +  3{a}^{2} b + 3a {b}^{2}  +  {b}^{3}

Also do not get mixed between

{a}^{3}  +  {b}^{3}

They both are not the same.

(a + b)^{3} ≠ {a}^{3}  +  {b}^{3}

What is the m∠N ? Can someone help me :)
Sauron [17]

Answer:

<h2>61°</h2>

Step-by-step explanation:

Use the sine law:

\dfrac{MO}{\sin(\angle N)}=\dfrac{NM}{\sin(\angle O)}

We have:

MO=18\\\\NM=6\\\\m\angle O=17^o\to\sin17^o\approx0.2924

Substitute:

\dfrac{18}{\sin(\angle N)}=\dfrac{6}{0.2924}         <em>cross multiply</em>

6\sin(\angle N)=(18)(0.2924)

6\sin(\angle N)=5.2632          <em>divide both sides by 6</em>

\sin(\angle N)=0.8772\to m\angle N\approx61^o

Is 272 oz greater than 20 lb
Karolina [17]
We know that 1 lb = 16 oz
So lets convert the 20 lb to oz and then compare the two quantities in consistent units.
If 1 lb = 16 oz then 20 lb are equal to 20*16 oz, that is
20 lb = 20*16 oz = 320 oz
therefore,
320 oz are greater than 272 oz, or,
20 lb are greater that 272 oz

Weather Station stayed The chance of it raining is 3/5. What percent would that be?
murzikaleks [220]
Answer:

60% chance of rain

Explanation;

A way you can get the percentage would be putting the fraction in your calculator. For example here it is 3/5, when the denominator is 5 you can say 20% for each whole number.

1/5 = 20% chance
2/5= 40% chance
3/5=60% chance
4/5= 80% chance
5/5= 100% chance
