The volume of premium antifreeze to be used is 60 gallons.

The volume of water to be used is 120 gallons

<h3>What is a percentage?</h3>

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Let the volume of 60% pure antifreeze be used to make 20% pure antifreeze.

= x gallons  

The volume of 20% pure antifreeze = 180 gallons

For 60% pure antifreeze:

C₁ = 60% , V₁ = x gallons

For 20% pure antifreeze :

C₂ = 20% , V₂ = 180  gallons

Applying,

C₁V₁ = C₂V₂

60 × x = 20 × 180

x = 60 gallons

The volume of 60% pure antifreeze used = 60 gallons.

The volume of water to be used.

= 180 - 60 gallons

= 120 gallons

Thus,

The volume of premium antifreeze to be used is 60 gallons.

The volume of water to be used is 120 gallons

Marcia bought a bag of red white and blue balloons for the party there were 49 balloons in the bag if there are twice as many re
DedPeter [7]

Answer:

Red color= 28 balloon

Blue color= 14 balloon

White color= 7 balloon

Step-by-step explanation:

Given: There are 49 balloons

As given, there are 2 red balloon equal to the number of blue balloon

∴ 2 red= blue\ balloon

Again given, there are 1/2 white balloon equal to the number of blue balloon.

∴ \frac{1}{2} \ white= blue\ balloon

As above equation, we can understand that:

2\ red= \frac{1}{2} \ white\ balloon

multiplying both side by 2

⇒ 4\ red= white\ balloon

which mean, if we have 2 blue balloon then we will have 4 red and 1 white balloon.

∴ Total combination of all color of balloon= 2+4+1= 7

Now, checking how many number of times combination can we have in 49 balloon.

\frac{49}{7}= 7 \ times

Next, finding number of balloon in each color.

Red color= 4\times 7= 28\ balloon

Blues color= 2\times 7= 14\ balloon

White color= 1\times 7= 7\ balloon
