So the ratio is 1 to 2 to 5
so basically 1 unit of soda water to 2 units of fruit punch to 5 units of ginger ale
total is 1+2+5=8 units
so 4 gallons=8 units
divide by 8
1/2 gallon=1 unit
soda water=1 unit=1/2 gallon
fruit punch=2 unit=1/2 times 2=1 gallon
ginger ale=5 unit=5 times 1/2=5/2=2 and 1/2 gallon
soda water=1/2 gallon
fruit punch concentrate=1 gallon
ginger ale=5/2 gallon or 2 and 1/2 gallon
You can know that the number is a multiple of another number if a number is divisible by another number. Then it can be a multiple of that number. :)

Eratosthenes then measured the angle of a shadow cast by a stick at noon on the summer solstice in Alexandria, and found it made an angle of about 7.2 degrees, or about 1/50 of a complete circle. ... Eratosthenes then used this to calculate the circumference of the Earth to be about 250,000 stadia.
Step-by-step explanation:
Since we are to complete the square, therefore I believe
the correct given should be:
x ^ 2 – 11 x
Take note of the symbol ^ which denotes that 2 is an exponent
of x.
The general form of a binomial equation is in the form of:
a x^2 + b x + c
Where in this case:
a = 1
b = -11
c = unknown
To complete the square, we have to find for the value of
c. This is calculated using the formula:
c = (b / 2) ^ 2
c = (-11 / 2) ^ 2
c = 30.25
Therefore the complete equation is:
<span>x ^ 2 – 11 x + 30.25</span>
We cannot agree with Danika. Why? Well, The reasoning is given as follows:
Two functions are inverses of each other if and only if it is true that the composition function is given by:

Everything is ok up to this point, right?. But let's prove that this is not fulfilled for these functions, then:

<span>
As you can see we did not obtain the function that matches the definition of </span>inverse functions. For that reason <em>we can't agree with Danika</em>.
