If the paint costs $1.50 per square meter, how much will she spend to cover the entire wall with paint?

Answers

To find the price to paint the entire wall, we just need to find the area of the wall and multiply by the price per square meter.

The area of a square is given by the product of the side length by itself. Since the measure of the side is 3 meters, the area is

[tex]A=3^2=9[/tex]

9 m².

The unitary price per square meter is $1.50. Multiplying this value by the area, we have

[tex]9\times1.5=13.5[/tex]

It will cost $13.50 to paint the wall.

The diagonal of a rectangular filed 135m long is 157m. What is the Width of the field?

Answers

To solve this exercise let's make a sketch of the rectangular field first:

The length, width, and diagonal of the rectangular field form a right triangle, to determine the width of the rectangle you can apply the Pythagorean theorem.

This theorem states that the square of the hypotenuse is equal to the sum of the square of the legs of the triangle.

[tex]a^2+b^2=c^2[/tex]

The diagonal is the hypotenuse of the triangle, the length is one of the legs "a" and the width is the other leg "b".

Write the theorem for b:

[tex]\begin{gathered} a^2-a^2+b^2=c^2-a^2 \\ b^2=c^2-a^2 \\ \sqrt[]{b^2}=\sqrt[]{c^2-a^2} \\ b=\sqrt[]{c^2-a^2} \end{gathered}[/tex]

Replace the expression with c=157 and a=135

[tex]\begin{gathered} b=\sqrt[]{157^2-135^2} \\ b=\sqrt[]{24649-18225} \\ b=\sqrt[]{6424} \\ b=80.149\approx80.15 \end{gathered}[/tex]

The width of the field is 80.15 meters.

Maximizing a function

The maximum value of any kind of a function is the place where the said function reaches its highest point, or vertex, on a graph. If your kind of quadratic equation has something as a negative of a term, it will also have a maximum value.

There are a bit of three ways to find that maximum, depending on which form of a quadratic function you have got.

Herein we can find the closed region ABC from the three equations or constraints given

and can mark the points as

A = (5,4)

B = (5, 12)

C = (11, 4)

if we put up the values of the points, we get

at (11, 4), Z = 4 x 11 + 2 x 4

Thus, the maximum point of the function can be calculated as (11,4)

How do you extract out the maximum or minimum value of a function?

We will at first set out the first derivative of the function to absolute zero and then solve for x to get the exact critical point.

Four people ordered total bill for soup and four people ordered stew is $31 .If only 2 people had ordered soup and one person ordered stew ,the bill would have been $12.25 .How much is each order of soup and stew ?

Answers

Let price of 1 soup be "x" and 1 stew be "y".

4 soup and 4 stew is $31, thus we can write:

[tex]4x+4y=31[/tex]

Also, given

2 soup and 1 stew costs $12.25, thus we can write:

[tex]2x+y=12.25[/tex]

Let' solve this for y and substitute it back to Equation 1. Then we will solve for x. The process is shown below:

[tex]y=12.25-2x[/tex]

Substituting,

[tex]\begin{gathered} 4x+4y=31 \\ 4x+4(12.25-2x)=31 \\ 4x+49-8x=31 \\ 49-31=8x-4x \\ 18=4x \\ x=\frac{18}{4} \\ x=4.5 \end{gathered}[/tex]

Three horse share five bales of hay equally. Five cows share eight bales of hay equally.

How much hay does each horse and each cow get?
Which animal gets more, a horse of a cow? How much more hay do they get?

Answers

How much hay does each horse and each cow get?

(a)The hay shared by 3 horses =  5 bales

So, the hay shared by 1 horse =  x

Rewriting the statements ,

3 h = 5 b  --(1)

1 h = x    -(2)

By applying cross multiplication method to (1) and (2)

3 (x) = 5

x = 5/3

The hay shared by 1 horse =  5/3

(b)The hay shared by 5 cows =  8 bales

So, the hay shared by 1 cow =  y

Rewriting the statements ,

5 c = 8 b  --(3)

1 c = y    -(4)

By applying cross multiplication method to (3) and (4)

5 (y) = 8

x = 8/5

The hay shared by 1 cow = 8/5

Which animal gets more, a horse of a cow?

Comparing the fractions,

The hay shared by 1 horse =  5/3  = 1.7

The hay shared by 1 cow = 8/5 = 1.6

1.7 > 1.6

So,  a horse gets more than a cow

How much more hay do they get?

Considering the difference of fractions,

Amount of more hay consumed = Hay shared by a horse - hay shared by a cow.

                                                     [tex]=\frac{5}{3} -\frac{8}{5} \\\\=\frac{25-24}{15} \\\\=\frac{1}{15}[/tex]
