Ruby wants to estimate the height of a streetlamp post on her block. She stands a certain
ira [324]

Answer: The height of street  would be 3.26 feet.

Step-by-step explanation:

Since we have given that

Angle of elevation = 71°

Distance traveled = 12 feet

Angle of elevation becomes 46°.

So, the height of the street lamp post would be

h=\dfrac{d}{\cot 46^\circ-\cot 71^\circ}\\\\h=\dfrac{12}{0.965-0.344}\\\\h=\dfrac{12}{0.620}\\\\h=3.26\ feet

Hence, the height of street  would be 3.26 feet.

Rudiy27
In the given question it is already mentioned that an adult drinks 54 fluid ounces of water daily. Also it is mentioned that Josey has already drank 700 milliliters of water.
Now fopr solving this problem we have to fist convert 64 ounces to liter and then convert 700 milliliter to liter and then only can we get the answer to the question.
We already know
1 ounce = 0.29 liter
64 ounce = 64 * 0.29 liter
               = 18.56 liter
So 18.56 liter is the daily recommendation for an adult to drink water
Again
1 milliliter = 0.001 liter
700 ml = 0.001 * 700 liter
           = 0.7 liter
So Josey has already drank 0.7 liters of water
Amount of water Josey still needs to drink = (18.56 - 0.7) liter
                                                                   = 17.86 liter
