Each time, you are dividing by 2, therefore making the common ratio $\frac{1}{2}$

se necesita llenar un galon de agua,en 2 litros se tarda 30 minutos.cuantos litros me hacen falta para completar el galon y cual

mariarad [96]

Answer: 1.78 L are needed to complete the gallon and it will take 29.66 min to completely fill it

Step-by-step explanation:

The question in english is:

A gallon of water needs to be filled, in 2 liters it takes 30 minutes. How many liters do I need to complete the gallon and what is the time it takes me to fill it?

We know 1 gallon is equal to 3.78 liters:

$1 gal=3.78 L$

In addition, we are told you have filled the gallon with $2 L$ at a rate of $\frac{2 L}{30 min}=0.06 L/min$ .

So, if we want to know how many liters are left to completely fill the gallon, we have to sbstract the $2 L$ to the total amount of a gallon:

$3.78 L-2 L=1.78 L$ This is the amount you need to complete the gallon

On the other hand, the rate is defined as:

$rate=\frac{Liters}{time}$

Isolating $time$ :

$time=\frac{Liters}{rate}$

Then, if we input the $1.78 L$ we need to fill the gallon we will have the time:

$time=\frac{1.78 L}{0.06 L/min}$

$time=29.66 min$ This is the time you need to fill the gallon

2% of the students at Hamilton Middle School have red hair. There are 700 students at Hamilton Middle

Makovka662 [10]

Answer:

14 students

Step-by-step explanation:

We can set up a percentage proportion to find 2% of 700.

$\frac{x}{700} = \frac{2}{100}$ , and we can use the cross products property to find the value of x.

$700\cdot2=1400\\\\1400\div100=14$

Hope this helped!

The ratio of the width to the the length of a painting is 3 to 7. If the painting is 42in long how wide is it

grandymaker [24]

Answer:

18 inches wide

Step-by-step explanation:

Since the ratio of width to length is 3:7 we can assume that the length will be substancially longer than the width. The length is given as 42 inches long. To find how big the scale factor is, we divide 42 by 7 to get 6. 6 is our scale factor. take 3 x 6 =18 inches wide.

Hope this helps! :)
