How would you describe a quadrillaterl that cannot be placed under a trapizoid in a hierarchy?

1 answer:

6 0

A quadrilateral is a shape that has four equal sides.
For example: squares, rectangles, parallelogram

A parallelogram is a quadrilateral with 2 pairs of parallel sides.
A square can't be in the hierarchy under trapezoids, rectangles,or rhombus.

How to convert fractions into decimals?

Margaret [11]

A fraction is just a short way to WRITE a division problem. It means "the top number divided by the bottom number". Take the two numbers from the fraction, DO the division, and you get the decimal.

Bob makes three different silverware - spoons, forks and knives. Each unit (dozen) of spoon gives him a profit of $9, forks of $

Gala2k [10]

Answer:

Solution is:

z (max) = 687.5

x₁ = 0

x₂ = 16

x₃ = 21

Step-by-step explanation:

From the problem statement we have:

Resources: machine time ( 183 h) labor (250 h) steel 185 (pounds)

Unit

Spoons 4 4 3

forks 4 9 2

knives5 5 5 4

Profit $ 9 20 17.5

Objective function z = 9*x₁ + 20*x₂ + 17.5 *x₃ to maximize

Subject to:

Availability of machine time : 183 h

4*x₁ + 4*x₂ + 5*x₃ ≤ 183

Availability of labor : 250 h

4*x₁ + 9*x₂ + 5*x₃ ≤ 250

Availability of steel : 185 pounds

3*x₁ + 2*x₂ + 4*x₃ ≤ 185

Requirement:

x₂ ≥ 16

General constraints:

x₁ ≥ 0 x₃ ≥ 0 all integers

After 6 iteration the solution using AtomZmath on-line solver

z (max) = 687.5

x₁ = 0

x₂ = 16

x₃ = 21

Resources used:

Machine time: 16* 4 + 21*5 = 64 + 105 = 169

remains 183 - 169 = 14 h

Labor: 16*9 + 21* 5 = 144 + 105 = 249

remains 250 - 249 = 1 h

Steel : 16*2 + 21*4 = 32 + 84 = 116

remains 185 - 116 = 69 pounds.

If it is decided that 20 units of forks are to be made then

we will need 4*4 = 16 h of machine time

9*4 = 36 h of labor

2*4 = 8 pounds of steel

We can get that from abandom to make one unit of x₃ ??

No because as we said we need 36 hours of labor ( we still have 1 we need 35 more hours ) if we make 20 x₃ insted of 21 we get only 5 hours.

z we got is maximum

What is the speed of a snake that moves 20 m in 5 seconds ?

pogonyaev

The speed of the snake is 8.95 miles per hour.

Step-by-step explanation:

Step 1:

The snake travels at a speed of 20 meters in 5 seconds.

We will need to determine the distance it covered in a single second. To do that we divide the distance covered in 5 seconds by 5.

The distance covered in 1 second $= \frac{20}{5} =4.$

So the snake is moving at a distance of 4 meters per second.

Step 2:

To convert the speed of the snake from meters per second to miles per hour, we multiply the speed in meters per second by 2.23694.

So to attain 4 meters per second in miles per hour, we multiply it by 2.23694.

4 meters per second $= 2.23694(4) = 8.94776$ miles per hour.

Rounding this off, we get the speed of the snake as 8.95 miles per hour.
