A 50-gallon rain barrel is filled to capacity. It drains at a rate of 10 gallons per minute. Write an equation to show how much
makvit [3.9K]

Answer:

The quantity of water drain after x min is 50 (0.9)^{x}  

Step-by-step explanation:

Given as :

Total capacity of rain barrel = 50 gallon

The rate of drain = 10 gallon per minutes

Let The quantity of water drain after x min = y

Now, according to question

The quantity of water drain after x min = Initial quantity of water ×  (1-\dfrac{\textrm rate}{100})^{\textrm time}

I.e The quantity of water drain after x min = 50 gallon ×  (1-\dfrac{\textrm 10}{100})^{\textrm x}

or,  The quantity of water drain after x min = 50 gallon × (0.9)^{x}

Hence the quantity of water drain after x min is 50 (0.9)^{x}  Answer

Answer:

384π cm³

Step-by-step explanation:

Formula for the volume of a cone is \displaystyle \large{\frac{1}{3}\pi r^2 h} where:—

  • r is radius
  • h is height

Our radius is given in an attachment which is 12 cm and height is 8 cm. Substitute these values in the formula:—

\displaystyle \large{V = \frac{1}{3}\pi (12)^2 \cdot 8}\\\displaystyle \large{V = \frac{1}{3}\pi \cdot 144 \cdot 8}\\\displaystyle \large{V = 48 \pi \cdot 8}\\\displaystyle \large{V = 384 \pi}

__________________________________________________________

<u>Summary</u>

  <u>Volume (Cone)</u>

\displaystyle \large{V = \frac{1}{3}\pi r^2 h} where:—

h is height or perpendicular.

r is radius.

  <u>Value of Pi (Commonly Used)</u>

\displaystyle \large{\pi \approx 3.14}
