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

for the problem 1/5g - 1/10 -g+ 1/3/10g -1/10 tyson created an equivalent expression using the folling steps is his final expres

Leokris [45]

No, Tyson's final expression is not equivalent to the initial expression.

<h3>Fraction addition;</h3>

According to Tyson's evaluation after collecting like terms; we have;

1/5g +(-1g) + 1(3/10g) + (-1/10) + (-1/10)

open parenthesis

1/5g - 1g + 3/10g - 1/10 - 1/10

Upon addition of like terms; we have;

(-1/2)g -1/5.

Hence, the correct expression is; (-1/2)g -1/5
