KIM [24]

Answer:

\theta=41.18^{\circ}

Step-by-step explanation:

Given that,

The height of the tree, h = 14 ft

The height of the shadow, b = 16 ft

We need to find the angle of elevation of the sun from the ground. Let the angle be θ. We can use trigonometry to find it. So,

\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{14}{16}\\\\\theta=41.18^{\circ}

So, the required angle of elevation of the sun is equal to 41.18^{\circ}.

If you ride your bike at an average speed of 15 mph, how long will it take you to ride to your grandparents’ home? Express your
saveliy_v [14]

Answer:

It will take you 0.24 hour to ride to your grandparents’ home

It will take you 14 minutes to ride to your grandparents’ home

Step-by-step explanation:

- Your average speed is 15 miles per hour

- The distance to grandmother home is 3.67 miles

- You need to know how long it will take you to do that

∵ Distance = speed × time

∵ Distance = 3.67 miles

∵ Speed = 15 miles per hour

- Substitute these values in the rule above

∴ 3.67 = 15 × time

- Divide both sides by 15 to find the time

∴ Time = 0.24 hour

* It will take you 0.24 hour to ride to your grandparents’ home

- You need to convert the time from hour to minutes

∵ 1 hour = 60 minutes

∵ Time = 0.24 hour

∴ Time = 0.24 × 60 = 14.4

∴ Time ≅ 14 minutes

* It will take you 14 minutes to ride to your grandparents’ home
