Answer:

Step-by-step explanation:

When you are looking for a pattern, look at one of the examples, makeup the pattern, then check it on the other examples.

Wrong answers may work on one, but not all the completed examples.

The right answer will work on all of the examples, then use that rule on the incomplete one.

So, I looked at the second one in the top row. The two bottom numbers, 5 + 13 makes 18. And 18÷3 (the top number, gives the center number) Check on other examples.

bottom + bottom=_

_÷top=center.

8+4=12, 12÷3 =4.

9+5=14, 14÷2=7

Both of these work.

So use the rule for the last one.

Add the bottom numbers, divide by the top number, fill it in the middle.

14+6=20

20÷4=5

Fill in 5.

ABC company wishes to minimize its cost. Its cost is given by the equation C = 3x+4y. The business constraints are as follows:

satela [25.4K]

Answer:

(2, 0)

Step-by-step explanation:

To solve this problem, we have to plot a graph. A graph was plotted using geogebra online graphing calculator. From the attached graph we can see the points that satisfy the constraints: (0,0), (2, 0), (2, 6), (6, 4). But since x,y > 0, this leaves us with B(2, 6), C(2, 0), D(6, 4)

The cost equation is C = 3x + 4y

At point B(2, 6): C = 3(2) + 4(6) = 30

At point C(2, 0): C = 3(2) + 4(0) = 6

At point D(6, 4): C = 3(6) + 4(4) = 34

Therefore the minimum cost is at C(2, 0)

What is the value of x so that the line segment with endpoints W(x, −2) and X(5, −4) is parallel to the line segment with endpoi

coldgirl [10]

Answer:

x equals six start fraction one over two end fraction

Step-by-step explanation:

Segments which are parallel have the same slope. Find the slope of of YZ. Then using that value, find the slope WX and solve for the value of x.

Slope of YZ is:

$m = \frac{y_2-y_1}{x_2-x_1}=\frac{2-6}{2-5}=\frac{-4}{-3}=\frac{4}{3}$

Since they are parallel, then WX has a slope of 4/3 too.

Slope of WX is:

$m = \frac{y_2-y_1}{x_2-x_1}\\\\\frac{4}{3}=\frac{-2--4}{x-5}\\\\\frac{4}{3}=\frac{2}{x-5}\\\\\frac{4}{3} (x-5) = 2\\\\4x -20=6\\\\4x = 26\\\\x = 6\frac{1}{2}$

LABEL YOUR ANSWERS PART A and PART B

velikii [3]

Answer:

A) CF CP CT FP FT PT

B) 5/6 or ~83.3%

Step-by-step explanation:

A) Each letter combination lists the outcomes of 2 salads. Order doesn't matter so CF and FC are the same thing and do not need to be listed twice.

B) Using Part A we know that there are 6 outcomes of 2 salads. 5 out of those 6 outcomes serve chicken, pasta or both. Only the day that serves both Fruit and Tuna is there an outcome that doesn't have Chicken and/or Pasta.

An open box is constructed of 3500 cm2 of cardboard. The box is a cuboid, with height hcm and square base of side xcm. What is t

erica [24]

Answer:

34.16 cm

Step-by-step explanation:

side of square base = x

height = h

area, A = 3500 cm^2

Area = x² + 4xh = 3500

4 xh = 3500 - x²

h = (3500 - x²)/4x

Volume = Area of base x height

V = x² h

V = x² (3500 - x²)/4x

V = (3500 x - x³) / 4

Differentiate volume with respect to x

dV/dx = (3500 - 3x²) / 4

It is equal to zero for maxima and minima

3500 - 3x² = 0

x = 34.16 cm

Now differentiate again

d²V/dx² = 6x / 4

It is negative so the volume is maximum.

Thus, for x = 34.16 cm, the volume is maximum.
