A man standing on a lighthouse at a height of 124 feet sights two boats directly in front of him. One is at an angle of depressi

Ksivusya [100]

Answer:

$125\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ABC find the length side BC

we know that

$tan(62\°)=\frac{124}{BC}$

$BC=\frac{124}{tan(62\°)}$

step 2

In the right triangle ABD find the length side BD

we know that

$tan(33\°)=\frac{124}{BD}$

$BD=\frac{124}{tan(33\°)}$

step 3

we know that

The distance between the two boats is the length side CD

$CD=BD-BC$

substitute the values

$CD=\frac{124}{tan(33\°)}-\frac{124}{tan(62\°)}=125\ ft$

How many 1/10s in 2 3/5

Umnica [9.8K]

It'd be clearer if you'd write: "How many tenths are there in 2 3/5?"

2 3/5 13/5

---------- = ---------- = 26

(1`/10) 1/10

There are 26 tenths in 2 3/5.

You take a 200 milligram dosage of aspirin. During each subsequent hour, the amount of medication in your bloodstream decreases

shepuryov [24]

Answer: The level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.

Step-by-step explanation:

If the amount is decreasing by r%, then the final amount is given by :-

$A=P(1-r)^t$

, where P = initial value , t= time

Given: P= 200 milligram, r= 35% = 0.35, t= 4 hours

The level of aspirin (mg) will be in your bloodstream in 4 hours = $200(1-0.35)^4$

$=200(0.65)^4\\\\=200\times 0.17850625\\\\=35.70125\approx35.70 \ mg$

Hence, the level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.
