Keywords:

<em>Tank, capacity, water, gallons, rule of three, variable, days </em>

For this case we have a tank with a capacity of 18,000 gallons, we want to know how many days 12000 gallons of the tank are emptied, with the use of water following an average rate of 450 gallons per day. So we make a rule of three according to the use of water per day:

450 gallons -----------> 1 day

12000 gallons -------> x

Where the variable "x" represents the number of days when water takes to reach 6000 gallons.

x = \frac {12000 * 1} {450}\\x = 26.67

Rounding the nearest whole we have:

x = 27

Answer:

For the tank to go from 18,000 gallons of water to 6000 gallons of water, it should take approximately 27 days, using the water at an average rate of 450 gallons per day.

x = 27\ days

a store advertises that customers can take 25% off the original price and ten take an extra 10% off. is this the same as a 35% o
maksim [4K]

Answer:

No, they are not the same.

Step-by-step explanation:

Lets say the price is 100 dollars. Lets start with the 25 and then 10 percent off. Since its 25% off we need to multiple the 100 dollar price by .75.

100*.75=75

Now that we have the 75 dollar price, we need to take off the 10%. We need to multiply the current price of 75 by .9

75*.9=67.5

The price after these 2 discounts is $67.50

Now lets do the 35% off right away. Since is 35% off we need to multiple our right of 100 by .65.

100*.65=65

The price after the 35% off is $65

So no, they are not the same.

forsale [732]

Answer:

N < 5

Step-by-step explanation:

"Makayla has $8 to buy tickets at the school fair. each ticket costs $1.50" can be written as $8 = ($1.50/ticket)*N.

Dividing both sides by ($1.50/ticket) results in

        $8

---------------------- = 5 1/3 tickets

 ($1.50/ticket)

or N < 5.

Please help i have no idea what are the excluded values to the equation y = 5 / (x^2 - 7x 10)?
Kryger [21]
Hello,

The excluded values are the roots of the denominator.

x²-7x+10=x²-2x-5x+10=x(x-2)-5(x-2)=(x-2)(x-5)

Roots of the denominator are x=2 and x=5

Let p: x &lt; −3
Serhud [2]

Answer:

B. x > 3 or x < −3

Step-by-step explanation:

We are given that,

p: x < −3

q: x > 3

Since, we know that,

The symbol v is known as 'disjunction', which is in other words represented by 'union', 'or'.

Thus, 'p ∨ q' means 'either p holds or q holds'.

Hence, we get,

'p ∨ q' is represented by 'either x <-3 or x > 3'.

i.e. 'p ∨ q' is represented by 'either x > 3 or x <-3'.

Thus, option B is correct.
