You are painting the outside of a 36-foot fence that goes around a square playground. There are 4 equal sections. You have painted 1/4 of one section. What fraction of the job have you completed?

Answer:

You have completed \frac{1}{16} of the job.

Step-by-step explanation:

You are painting the outside of a 36 foot fence.

There are 4 equal sections of the fence = 36 ÷ 4 = 9 feet one section.

You have painted \frac{1}{4} of one section.

9 × \frac{1}{4} = \frac{9}{4} feet.

you have painted \frac{9}{4} feet of one section.

Now the fraction of total job done = \frac{9}{4\times 36} = \frac{1}{16}

You have completed \frac{1}{16} of the job.

QUESTION POSTED AT 19/02/2020 - 01:28 PM

Thomas buys a cardboard sheet that is 12 by 8 inches. Create an equation for this situation, find the zeros, and sketch the function. What is the size of the cutout he needs to make so that he can fit the maximum amount of food in the box? If Thomas wants a volume of 12 cubic inches, what size does the cutout need to be? What would be the dimensions of this box? Using complete sentences, explain the connection between the cutout and the volume of the box. Design an equation that would work for any cardboard sheet length, q, and width, p.

For the answer to the question above,

1. If we let x as the side of the square cut-out, the formula for the capacity (volume) of the food dish is:
V = (12 - 2x)(8 - 2x)(x)
V = 96x - 40x^2 + 4x^3
To find the zeros, we equate the equation to 0, so, the values of x that would result to zero would be:
x = 0, 6, 4

2. To get the value of x to obtain the maximum capacity, we differentiate the equation, equate it to zero, and solve for x.
dV/dx = 96 - 80x + 12x^2 = 0
x = 5.10, 1.57
The value of x that would give the maximum capacity is x = 1.57

3. If the volume of the box is 12, then the value of x can be solved using:
12 = 96x - 40x^2 + 4x^3
x = 0.13, 6.22, 3.65
The permissible value of x is 0.13 and 3.65

4. Increasing the cutout of the box increases the volume until its dimension reaches 1.57. After that, the value of the volume decreases it reaches 4.

5. V = (q -2x) (p - 2x) (x)

How would you describe a transformation to someone who has never taken geometry before? explain what a transformation is and state how a transformation can be used to solve a problem in real life

In mathematics, 'transforming' an object mean that you change its appearance.This can be done in four ways .Any figure can be Rotated ,Reflected or Translated from its original place to get a transformed figure. After these transformations, the shape will still have exactly the same size, area, angle sizes and line lengths.

The original shape is called 'object' and the transformed shape is called the 'image'. The transformed image will be 'congruent' to the original object. It can change its size so we can say transformed images are similar.

The reflection of mountain in a lake is an example of reflection.Transformations produce similar figures which helps us find width of river in our daily life.

Which strategy would you use to divide 36÷6?explain why you chose that strategy.

Answer:

Searching.

Step-by-step explanation:

I would use the strategy of searching one number that multiplied by 6 the result is 36. That strategy is useful to know the inverse operation of division.

36/6 = x (the six is dividing, to pass it to the other side you use the inverse operation, that is multiplication.)

36 = 6x (the result is one number that mulptiplied by 6 is 36).
