a medication prescription states 1/4 tablet twice a day per 20kg the peson weight is 211 pounds. how many tablets should be take
Black_prince [1.1K]
<h2>Hello!</h2>

The answer is: 1.187 tablets each time (twice a day)

<h2>Why?</h2>

From the statement we know that 0.25 tablet (1/4) should be taken twice a day per 20 kg, it makes 0.5 table a day, per 20 kg.

First, we need to convert the given weight unit (pounds) to kg:

1 Pound=0.45Kg

So,

211Pounds*\frac{0.45Kg}{1Pound}= 94.95Kg=95Kg

A weight of 95 Kg, means 4.75 times more than the given information of 0.5 table a day, per 20 Kg

\frac{95Kg}{20Kg}=4.75

Then,

4.75*(0.5)=2.375

So,

For a weight of 95 Kg,  2.375  tablets should be taken a day, or 1.187  tablets each time.

Have a nice day!

Find the measure of each unknown angle.
tekilochka [14]

Answer:

= 56°

= 34°

Step-by-step explanation:

3x + 5 + 2x = 90°

3x + 2x + 5 = 90°

5x + 5 = 90°

5x = 90 - 5

5x = 85

x = 85/5

x = 17

3x + 5

= 3(17) + 5

= 51 + 5

= 56°

2x

= 2(17)

= 34°

The time period, T, of a simple pendulum is directly proportional to the square root of the length, d, of the pendulum.
bearhunter [10]

Answer: T= 3.54

Step-by-step explanation:

Step 1

Given that

The time period, T, s doirectly proportional  to the square root of the length, d, of the pendulum, we have that

T  ∝  \sqrt{d}

Introducing the constant of proportionality, we have that

T= K\sqrt{d}.

Step 2

When d=6, T=5, K =?

T= K\sqrt{d}.

5 = k\sqrt{6}

5=  k x 2.44949

k =5/2.44949

k =2.041

Therefore, when d = 3 , T= ?

T= K\sqrt{d}

T= 2.041 x \sqrt{3}

T= 3.53511≈ 3.54
