Answer:

<h2>3.5 gallons of water.</h2>

Step-by-step explanation:

According to the problem, water and lemon have the ratio 7:1, 7 parts of water per 1 part of lemon.

Also, we know that one gallon have four quarts, and we want to make 1 gallon of lemonade. So, the amount of water would be x, because the question is about water, and the amount of lemonade would be 4 \ quarts - x, because it would be the difference between the total 4 quarts (1 gallon) and the amount of water.

Now, using the ratios, we have:

\frac{7 \ water}{1 \ lemon}=\frac{x \ water}{4 - x \ lemon} \\28-7x=x\\7x+x=28\\8x=28\\x=\frac{28}{8}=3.5

Therefore, the amount of water needed is 3.5 gallons, and 0.5 gallons of lemon.

In order to solve this problem, we need our knowledge on ratio and proportion for us to set up an equation. <span>A </span>proportion<span> is an equation with a </span>ratio<span> on each side. It is a statement that two </span>ratios<span> are equal. </span>We do as follows:

7 parts water / 1 part lemon = 4 quarts - x / x

where x is the quarts lemon needed

Solving for x,

x = 0.5
water needed = 4-x = 3.5 quarts water is needed

Annette [7]

hours each day.

Step-by-step explanation:

The given function models the number of cars that are put through a quality control test each hour at a car production factory.

The given function is

We need to find the number of hours does the quality control facility operate each day.

Rewrite the given function it factored form.

Taking out the common factors from each parenthesis.

The factored form of given function is c(t)=-(t-10)(t+2).

Equate the function equal to 0 to find the x-intercept.

Number of hours cannot be negative. So from t=0 to t=10 quality control facility operate the cars.

Therefore the quality control facility operates for 10 hours each day.

The exterior angles of a polygon all add to 360, if you need to find an exterior angle when given the number of sides and that all angles are equal you simply do: 360/ number of sides.
When you need to find the exterior angle when given an interior angle, you do: 180- interior angle.
