30% is equivalent to 0.3. So 15 x 0.3 = 4.5. Therefore, 30% of $15 is $4.50.
Answer:
$53.70
Step-by-step explanation:
I worked it out I think this is the answer
Answer: 111.4m
Explanation:
1) Trigonometric ratios
You only need to use tangent ratio.
tangent ratio = opposite-leg / adjacent-leg = balloon height / horizontal distance
2) First, find the height of the ballon when he is watching at an angle of elevation of 28°
tangent ratio = opposite-leg / adjacent-leg = balloon height / horizontal distance
tan(28°) = balloon height/65m ⇒balloon height = tan(28°)×65m
balloon height = 34.56m
3) Second, find the height of the balloon,when he is watching at an angle of elevation of 66°
tan(66°) = height of the balloon / 65m ⇒ height of the balloon = tan(66°)×65m
height of the balloon = 145.99m
4) Vertical distance the balloon ascended while Charlie watched.
Subtract the final initial height from the final height:
145.99m - 34.56m = 111.43m
4) Round to the nearest tenth: 111.4 m
Answer:
30
Step-by-step explanation:
Each 1 biography has 5 possible mystery novels to choose from so, for each 6 books you could choose out of 5 possible mystery books and with that being said, 5 × 6 = 30
