A circular cloud of poison gas from a factory explosion is expanding so that t hours after the explosion the radius of the cloud
diamong [38]

Answer:

6000π m²/h

Step-by-step explanation:

Area of the circular cloud =πr²----------------------------------------- (1)

Radius as a function of time = R(t)=50+20t------------------------ (2)

dA/dt = (dA/dr) x (dr/dt)-----------------------------------------------------(3)

dA/dr  =  2πr

dr/dt   = 20

After 5 hours, the radius of the cloud will be :

R(5)=50+20(5)

     =   150 meters

Substituting into (3)

dA/dt =   2π(150)  x 20

         =   6000π m²/h

the result of an experiment was 117.755 particles per milliliter. write the decimal as a mixed number.
nordsb [41]

The result of experiment in mixed fraction form is 117\frac{151}{200}  particles per milliliter.

<h3>What is the result of the experiment in mixed fraction form?</h3>

To convert decimal to fraction, we the decimal number over 1 and multiply both the numerator and denominator by power of 10.

Given the data in the question;

  • Result of experiment in decimal form = 117.755
  • Result of experiment in mixed fraction form = ?

In 117.755, we have 3 numbers to the right of the decimal point.

We have 10³ which is the same as 1000.

\frac{117.755}{1} * \frac{1000}{1000}\\\\\frac{117755}{1000}

Next, we divide both the numerator and the denominator with their Greatest Common Factor.

Greatest Common Factor of 117755 and 1000 is 5

\frac{\frac{117755}{5} }{\frac{1000}{5} } = \frac{23551}{200}

Now, we can get 200 out of 23551 exactly 117 times, since what remained is not divisible by 200, we leave it as a remainder [151].

We can now write this in a mixed fraction form as;

117\frac{151}{200}

Therefore, the result of experiment in mixed fraction form is 117\frac{151}{200}  particles per milliliter.
