Nikitich [7]

Answer:

z (min ) = 0.4167    $

x = 8,33 oz

y = 0

Step-by-step explanation:

Table:

                              Vitamin A        Vitamin B         Cost $/oz

Wheat  (x)                10.5                    2.4                   0.05          

Oats     (y)                 6                       1.8                    0.10          

Requirements           48 (mg)              20 (mg)

Requirements           1,693 (oz)           0,7054 (oz)

The problem is minimized z subject to two constraint

z  =  0.05*x  + 0.1*y   to minimize

Subject to:

Requirement  of  Vitamin A

10.5*x + 6 * y  ≥  48

Requirement  of  Vitamin B

2.4*x   + 1.8*y ≥  20

x≥0  y≥0

Using  the on-line solver AtomZmaths and after 3 iterations the solution is:

z (min ) = 0.4167    $

x = 8,33 oz

y = 0

devlian [24]

Answer:

  rhombus

Step-by-step explanation:

It is helpful to plot the points on a graph. There, you can see that the rise and run of each segment are 1 and 4 (or vice versa). This tells you they are the same length, but not perpendicular.

A quadrilateral with all sides the same length, but not perpendicular, is a rhombus.

The figure shows the front side of a metal desk in the shape of a trapezoid.
Alenkinab [10]

Answer:

Area of trapezoid is 16ft^2.

Therefore, option 2nd  is correct.

Step-by-step explanation:

We have been given both the sides a=3 and b=5.

And height that is h=4

We will use the formula find the area of trapezoid is:

\frac{a+b}{2}\cdot h

Substitute the formula we get:

\frac{3+5}{2}\cdot 4

\Rightarrow \frac{8}{2}\cdot 4

\Rightarrow 16.

Area of trapezoid is 16ft^2.

Therefore, option 2nd  is correct.
