How do you know where to place the decimal in a quotient?

It all depends on the divisor.

You need to make sure the decimal of the divisor is at the end.

For example, 2.09 divided by 0.19

You need to move the decimal point of 0.19 two times to the right so the decimal point is at the end.

If the divisor is a whole number, the decimal would stay at the same position.

For example, 25.5 divided by 5, the decimal would stay since 5's decimal point is already at the end (5.)

See attachment if you want to see it visual. Writing on computer is hard tho.

Answer:

Take note that the quotient's decimal point is precisely above the dividend's decimal point. To divide a decimal by a whole number, move the decimal point in the quotient above the decimal point in the dividend and divide as usual.

Step-by-step explanation:

I have corner points of:
WARRIOR [948]
The points you found are the vertices of the feasible region. I agree with the first three points you got. However, the last point should be (25/11, 35/11). This point is at the of the intersection of the two lines 8x-y = 15 and 3x+y = 10

So the four vertex points are:
(1,9)
(1,7)
(3,9)
(25/11, 35/11)

Plug each of those points, one at a time, into the objective function z = 7x+2y. The goal is to find the largest value of z

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

Plug in (x,y) = (1,9)
z = 7x+2y
z = 7(1)+2(9)
z = 7+18
z = 25
We'll use this value later. 
So let's call it A. Let A = 25

Plug in (x,y) = (1,7)
z = 7x+2y
z = 7(1)+2(7)
z = 7+14
z = 21
Call this value B = 21 so we can refer to it later

Plug in (x,y) = (3,9)
z = 7x+2y
z = 7(3)+2(9)
z = 21+18
z = 39
Let C = 39 so we can use it later

Finally, plug in (x,y) = (25/11, 35/11)
z = 7x+2y
z = 7(25/11)+2(35/11)
z = 175/11 + 70/11
z = 245/11
z = 22.2727 which is approximate
Let D = 22.2727

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

In summary, we found
A = 25
B = 21
C = 39
D = 22.2727

The value C = 39 is the largest of the four results. This value corresponded to (x,y) = (3,9)

Therefore the max value of z is z = 39 and it happens when (x,y) = (3,9)

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

Final Answer: 39

The table compares the prices of four types of fruit. Which fruit is the best to buy?
taurus [48]

Divide the price by the quantity:

Bananas = 5.40 / 6 = 0.90 each

Oranges = 2.56/8 = 0.32 each

Apples = 4.68 / 12 = 0.39 each

Mangos = 3.16 / 4 = 0.79 each

Oranges have the lowest price each so are the best buy.
