Answer:
14) 21.136505024965 m
15) 43.076759215619 km
Step-by-step explanation:
14)
let h be the height of the lighthouse:
tan(41.3) = 18.7/h
Then
h = 18.7÷tan(41.5)
= 21.136505024965 m
………………………………………
15)
90-71.4 =18.6
Let s be the distance that the plane flew
towards the south:
tan(90 - 71.4) = s/128
Then
tan(18.6) = s/128
Then
s = tan(18.6)×128
= 43.076759215619 km
For this case, the first thing to do is to model the rectangular sandbox as a rectangular prism.
The volume of the prism is given by:
Where,
- <em>w: width </em>
- <em>l: length </em>
- <em>h: height </em>
Therefore, replacing values we have:
We observed that:
Therefore, the sandbox is not completely filled.
Answer:
the sandbox will hold of sand
Jodi purchase is not enough sand to fill the sandbox to the top.
