A bathtub contains 12 gallons of water. With these 12 gallons, the bathtub is only 30% full. How many gallons of water can the b

Pachacha [2.7K]

Answer:

40 gallons

Step-by-step explanation:

Let the number of gallons that would completely fill the bathtub be represented by N.

Since 12 gallons of water gives 30% of the number of gallons to fill the bathtub, then;

30% of N = 12

$\frac{30}{100}$ x N = 12

30N = 12 x 100

30N = 1200

divide both sides by 30,

N = $\frac{1200}{30}$

= 40

The number of gallons that would completely fill the bathtub is 40 gallons.

alekssr [168]

Answer:

at least $1,050,000

Step-by-step explanation:

Deandre's salary will be ...

12000 + 0.06·sales

He wants that to be at least 75000, so the sales must meet the requirement ...

12000 + 0.06·sales ≥ 75000

0.06·sales ≥ 63000 . . . . . . . . . . . . subtract 12000

sales ≥ 63000/0.06 . . . . . . . . . . . .divide by 0.06

sales ≥ 1,050,000 . . . . . . . . . . . . . .evaluate

He will need to have at least $1,050,000 in total sales to have a yearly income at least $75,000.

Answer:

Then, the object will take 29.11 min to travel $4\frac{9}{10}miles$

Step-by-step explanation:

When an object is moving at a steady speed, we can calculate the time it would take to travel a given distance using the following formula:

$time=\frac{distance}{speed}$ (equation 1)

In this particular, both the given speed and distance are mixed fractions so we'll first convert them into improper fractions to operate more easily:

$speed=10\frac{1}{10} \frac{mi}{h} =\frac{(10*10)+1}{10} \frac{mi}{h}=\frac{101}{10} \frac{mi}{h}$

$distance=4\frac{9}{10}mi=\frac{(4*10)+9}{10}mi=\frac{49}{10}mi$

So, now we can calculate the time using the equation 1:

$time=\frac{distance}{speed}=\frac{\frac{49}{10}mi }{\frac{101}{10} \frac{mi}{h} } =\frac{49*10}{101*10} h$

$time=\frac{49}{101}h=0.49h$

And, if we want the result in minutes:

$time=\frac{49}{101}h*\frac{60min}{1h} =29.11min$

Then, the object will take 29.11 min to travel $4\frac{9}{10}miles$
