(sin30° + cos30°) – (sin 60° + cos60°)​

Mathematics
1 answer:
Darya [45]3 years ago
8 0

Answer:

0

Step-by-step explanation:

Sin 30° = ½

Cos 30° = √3/2

Sin 60° = √3/2

Cos 60° = ½

Therefore,

(½ + √3/2) - (√3/2 + ½)

\frac{1 +  \sqrt[]{3} }{2}  -  \frac{ \sqrt{3 + 1} }{ 2 }

\frac{1 +  \sqrt{3}  -  \sqrt{3}  -  1}{2}

\frac{0 - 0}{2}

Answer: 0

***WILL GIVE MEDAL TO WHOEVER HELPS***
Bezzdna [24]
<span>x+y = 23 and 2x+3y=55; The wording of the answer choices were confusing, but both of these come together to make the correct answer. First, you need x (number of bracelets) + y (number of necklaces) to determine how many of each were sold. Then, you add 2x (cost of each bracelet x bracelets sold) and 3y (same as bracelets but for necklaces). This results in the total amount sold.</span>

If 100% of a number is 15, what is 50% of the number?
anzhelika [568]

Answer:

Let n be the number

100% of a number is 15 is written as: 100% × n = 15

100% = 100 / 100 = 1

Hence

100% × n = n = 15

We now need to find 50% of the number

50% of 15 = (50 / 100) × 15 = 750 / 100 = 7.5

Step-by-step explanation:

Mark me as brainliest pls
