Answer:

The flag pole is 38.96 feet tall.

Step-by-step explanation:

The angle of depression from the top of the flagpole to an object on the ground is 33°.

The object is 60 feet from the base of the cliff.

We need to find the height of the flag pole.

Here, base, B = 60 feet

We know that,

\tan\theta=\dfrac{P}{B}

Put all the values to find P.

P=B\times \tan\theta\\\\P=60\times \tan(33)\\\\P=38.96\ ft

So, the flag pole is 38.96 feet tall.

natali 33 [55]

Answer:

36 minutes

Step-by-step explanation:

Depth of the fjord = 1308 m

Rate at which the submersible dives = 35 meters/minute

Distance to the bottom of the fjord should be 48 m

Distance the submersible has to go underwater is 1308-48=1260\ \text{m}

Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives

\dfrac{1263}{35}=36\ \text{minutes}

The time taken by the submersible to dive the required distance is 36 minutes.

juin [17]

Answer:

The solution required per dosage is 3 mL and 9.175 mL of solution is required for the recommended dosage in a day.

Step-by-step explanation:

As the weight of the child is given as 27 lbs. Converting it to kgs as

1 kg =2.2042 lb

So 27 lbs=27/2.2042 kg

The weight of the kid in kg is 12.247 kg.

As the recommended dosage is 0.3 mg/kg/hour so for the weight of the kid the recommended dosage for the day is given as

Recommended dosage=0.3*12.247 =3.67 mg per day

As the concentration is given as 2 mg/5mL

So for each dose the solution is found as

Solution per dose is as Dose Value/Concentration=1.2/(2/5)=3 mL

So the solution required per dosage is 3 mL

Now for the solution required per day is given as

Solution per day is as =Dose Value/Concentration=3.67/(2/5)=9.175 mL

So 9.175 mL of solution is required for the recommended dosage in a day.
