Sin 30°-cos 30°÷ sin 60°​

Mathematics
1 answer:
Vilka [71]2 years ago
6 0

Answer:

-1/2

Step-by-step explanation:

sin(30 degrees) = sin (pi/6) = 1/2

cos(30 degrees) = cos (pi/6) = [sqrt(3)]/2]

sin (60 degrees) = sin(pi/3) = [sqrt(3)]/2]

1/2 - [sqrt(3)/2] / [sqrt(3)/2] = -1/2

Alex777 [14]

Answer:

1. Yes

2. Yes

Step-by-step explanation:

Leah wrote 2 different fractions with the same denominator. Both fractions were less than 1.

1. Can their sum equal 1?

Let Leah fractions be \dfrac{6}{7} and \dfrac{1}{7}. Both these fractions have the same denominators and are less than 1. Find their sum:

\dfrac{6}{7}+\dfrac{1}{7}=\dfrac{7}{7}=1

2. Can their sum be greater than 1?

Let Leah fractions be \dfrac{6}{7} and \dfrac{5}{7}. Both these fractions have the same denominators and are less than 1. Find their sum:

\dfrac{6}{7}+\dfrac{5}{7}=\dfrac{11}{7}=1\dfrac{4}{7}>1

DochEvi [55]
If Molly ate 1/3 of the bag of chips on Friday, that means that there is 2/3 of the bag left.

Then, she eats 1/2 of what is left in the bag (2/3).  (We multiply these fractions to find the answer.)

1/2 * 2/3 = 1/3.

<span>Therefore, Molly at 1/3 of the entire bag on Saturday. </span>
