Answer:

Step-by-step explanation:
A right angled triangle is given to us and we would like to find out the value of sin(A) .
From the triangle we can see that the measure of angle BAC is 30° . Therefore ,

On using sin both sides ,

As we know that the value of sin30° = 1/2. So;

Simplify by converting it into decimal ,

<u>Hence</u><u> </u><u>option</u><u> </u><u>B</u><u> </u><u>is</u><u> </u><u>correct</u><u> </u><u>.</u>
And we are done!
Answer:
We conclude that 84% of books are not best-sellers.
Step-by-step explanation:
A publisher estimates that 8 of every 50 books become national best-sellers.
Means 16% of books are best sellers.
- Because 16% of 50 books = 8 ∵ 16/100 × 50 = 8
Thus,
Bestseller books = 16%
Books that are not national best sellers = 100% -16% = 84%
Therefore, we conclude that 84% of books are not best-sellers.
Answer:
d = 9
Step-by-step explanation:
Given
1 =
d - 2 ( multiply through by 3 to clear the fraction )
3 = d - 6 ( add 6 to both sides )
9 = d
