Answer:
it will take 20 hours for 18 bakers to complete the same order
Step-by-step explanation:
15 bakers take 24 hours
18 bakers take x hours
15 * 24 = 360 "baking hours"
18 * x = 18x " baking hours"
360 baking hours = 18x baking hours
360 = 18x
18 18
20 = x
x = 20 hours
Step-by-step explanation:
To solve this question I would use the sin rule.
The sin rule states that
Therefore if you substitute in your numbers you get:
If you rearrange that you get:
Therefore a = 17.3 Inches (to 3 sf)
This can also be done with basic trigonometry where you would get
Rearranging to
meaning the answer is 13.7 inches

Answer:
- a) 6.5 seconds
- b) 13 seconds
- c) 679 ft
Step-by-step explanation:
<u>Given function:</u>
a) <u>Maximum height is the vertex.</u> The ball reaches the maximum after:
- h = -208/2(-16) = 6.5 seconds
b) <u>Time the ball was in the air:</u>
Solving we get approximately t = 13 seconds
c) <u>Maximum height is at vertex, we found t above:</u>
- h(6.5) = -16(6.5)^2 + 208*6.5 + 3 = 679 ft
