Answer:

In a gallon there are approximately 3.79 liters

Step-by-step explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other ( or when one magnitude decreases, so does the other), the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

Then

$x=\frac{c*b}{a}$

Taking into account that there are 128 fluid ounces in a gallon, you can determine how many liters are in a gallon by applying a rule of three as follows: If there are 33.8 fluid ounces in a liter, how many liters are in 128 fluid ounces (a gallon)?

$liters=\frac{128 fluid ounces*1 liter}{33.8 fluid ounces}$

liters= 3.79 liters

Then, in a gallon there are approximately 3.79 liters

You have 10 liters of juice that is 40% juice and 60% water. You want the mixture to be 70% juice and 30% water. How many liters

damaskus [11]

Answer:

14 liters

Step-by-step explanation:

10 liters : 4 liters of juice and 6 liters of water

4/10 of juice and 6/10 of water

make it to 70% of juice and 30% of water

add 14 liters of juice

14/20=70% of juice

6/20=30% of water

Choose all of the system of equations which have no solution. x + 2y = 10 and 2y = 6 + 5x x = 8 − y and y = 6 + 5x 3x + 2y = 5 a

nirvana33 [79]

Answer:

Third and fourth systems

Step-by-step explanation:

Let's check the first system:

x + 2y = 10

2y = 6 + 5x

Isolating x in the first equation, we have x = 10 - 2y. Applying that in the second equation we have:

2y = 6 + 5(10-2y)

2y = 6 + 50 - 10y

12y = 56

y = 4.6667

from the first equation, we have that x + 2*4.6667 = 10 -> x = 0.6667

So this system has a solution.

Checking now the second system:

x = 8 − y

y = 6 + 5x

using y from the second equation in the first equation, we have:

x = 8 - 6 - 5x

6x = 2

x = 0.3333

then, in the second equation:

y = 6 + 5*0.3333 = 7.6666

This system also has a solution

Third system:

3x + 2y = 5

2y = 6 − 3x

The second equation can be rewritten as:

3x + 2y = 6

We can see from both equation that the same expression (3x + 2y) has two values (5 and 6). So we can't solve this system.

Fourth system:

3x = 2 − 4y

4y = 7 − 3x

The first equation can be rewritten as 3x + 4y = 2

The second equation can be rewritten as 3x + 4y = 7

We can see from both equation that the same expression (3x + 4y) has two values (2 and 7). So we can't solve this system.

So, the systems that have no solution are the third and fourth systems

a beetle is 1.8cm long. a drawing of the beetle is made using a scale of 5:1. what is the length of the beetle in the drawing?

Delvig [45]

Answer: The length of the beetle in the drawing is 9 cm.

Step-by-step explanation:

Hi, since is a scaling up scale, we have to multiply the original length of the beetle (1.8 cm) by 5 to obtain the length of the beetle in the drawing.

Mathematically speaking

5 x 1.8 = 9 cm

The length of the beetle in the drawing is 9 cm.

This type of scale is used to increase in size.

Feel free to ask for more if needed or if you did not understand something.
