Answer: A proportion is simply a statement that two ratios are equal.

Example: 2:6 = 1:3

To get that you do this: 2:6 ÷ 2:2 = 1:3

-----------------------------------------------------------

Example 2: 5:10 = 1:2

To get that you do this: 5:10 ÷ 2:2 = 1:2

The constraints of a problem are listed below. What are the vertices of the feasible region?<br>

Mamont248 [21]

Answer:

Option 4 : $(0.\frac{3}{2} ) \ , \ (0,2) \ , \ (6,0) \ , \ (\frac{9}{4} ,0)$

Step-by-step explanation:

<u>See the attached figure:</u>

To find the vertices of the feasible region, we need to graph the constraints, then find the area included by them, then calculate the vertices which is the intersection between each two of them.

As shown, the shaded area represents the solution of the constraints

So, the vertices of the feasible region are:

$(0.\frac{3}{2} ) \ , \ (0,2) \ , \ (6,0) \ , \ (\frac{9}{4} ,0)$

how many numbers did bill wrote if he wrote all the natural numbers between w and v not including w and v

dexar [7]

Answer:

v - w - 1

Step-by-step explanation:

Try an experiment with a small, specific set of numbers like:

4, 5, 6, 7, 8, 9, 10 w = 4 and v = 10.

There are 5 numbers in the list, not counting the first and last. Is this related to the difference between v and w? v - w = 6, one more than 5.

The number of natural numbers between w and v, not including w and v, is v - w - 1.

A pound of guinea pig pellets is about 3 cups of food.Each guinea pig eats 1/4 cup is pellets a day. How many days will the pell

kompoz [17]

Answer:

The pellet will last after 12 days

Step-by-step explanation:

* Lets change the story problem to equations to solve it

- There is a pound of guinea pig pellets

- One pound of pellets is about three cups of food

- Each guinea pig eats 1/4 cup of pellets a day

* Lets use these information to solve the problem

∵ One pound of guinea = 3 cups of food

∵ The guinea pig eats 1/4 cup a day

- The pig can finish one cup in four days

∵ The number of days = number of cups ÷ the eaten in a day

∵ The number of cup = 3 cups

∵ The eaten pellets in a day = 1/4

∴ The number of days = 3 ÷ 1/4 = 3 × 4/1 = 12 days

* The pellet will last after 12 days
