<u>Given</u><u> </u><u>that</u><u>:</u><u>-</u>
→ 1 sandwich = 2 slices of bread.
→ 1 hiker = 1 sandwich.
→ Then we have to find number of bread slices for n hikers .
→ Number of bread slices for 1 hiker = 2
→ Number of bread slices for 2 hikers = 2 × 2
→ For 3 hikers = 3 × 2
So in similar way
→ Number of bread slices for n hikers = 2×n → 2n
So <u>2</u><u>n</u><u> </u> is the answer.

<u><em>Answer:</em></u>sin B = 0.65
<u><em>Explanation:</em></u>To solve this question, we will need to use <u>the sine law</u> that is shown in the attached image.
<u>Here, we have:</u>
c = 8
b = 6
angle C = 60</span>°<span>
<u>Therefore:</u>
