You charge $2 per square yard to paint.Which equation can you solve to find the amount you will charge to paint a triangular wall with a base of 4 yards and a height of 6 yards?

Answer:

Step-by-step explanation:

Question 1

The distance between the chords is sum of the distances between the center and the midpoint of the chords

The segments between the center to the midpoints of the chords for right triangles with one side being the radius.

The distance is:

------------------------------------------

Question 2

Midpoint of the side, the center and the vertex form a right triangle with 30° angle at the vertex.

Let the radius be r, the distance from the center to the side be h

Then we have:

As per property of 30°-60°=90° triangle, the side opposite to 30° is half of the hypotenuse. In this case, h = r/2 or r = 2h

Substitute r into equation above and solve for h:

Find the value of r:

Answer:

x = - 4, x = 1

Step-by-step explanation:

The solutions to the quadratic are the values of x where the graph crosses the x- axis.

The graph crosses the x- axis at x = - 4, x = 1

Thus the solutions are x = - 4 , x = 1

The value of x is given from proportion and x = 9

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the first polygon and second polygon be similar

So , the ratio of their corresponding sides will also be similar

Substituting the values in the equation , we get

( x -1 ) / 6 = 16 / 12   be equation (1)

On simplifying the equation , we get

Multiply by 6 on both sides of the equation , we get

( x - 1 ) = ( 16 x 6 ) / 12

( x - 1 ) = 16 / 2

On simplifying the equation , we get

x - 1 = 8

Adding 1 on both sides of the equation , we get

x = 9

And ,

( y + 1 ) / 21 = 32 / 24   be equation (2)

On simplifying the equation , we get

Multiply by 21 on both sides of the equation , we get

( y + 1 ) = ( 4 x 21 ) / 3

y + 1 = 4 x 7

y + 1 = 28

Subtracting 1 on both sides of the equation , we get

y = 27

Hence , the value of x is 9

Answer:

x=20

y=35

Step-by-step explanation:

lets say:

x+y=55

2x=y+5

y being the bigger number

dexcribe y in terms of x:

55-x=y

now replace y in the second equation

2x=55-x+5

2x=60-x

3x=60

x=20

so y=35

The cost price of the article that makes a profit of $100 will be $400.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

When an article is sold for $100 a profit of 25% is made on the cost price.

Let 'x' be the cost price of the article. Then the equation is given as,

25% of x = $100

Simplify the expression, then we have

0.25x = $100

x = $100 / 0.25

x = $400

The cost price of the article that makes a profit of $100 will be $400.

Answer:

No because the given numbers do not satisfy the equation a² + b² = c²

Answer:

No, because the given numbers satisfy the equation a^2+b^2=c^2.

Step-by-step explanation:

The Pythagorean triple 2, 3, 4. We can put it in our formula, a^2+b^2=c^2. So, that will equal:

2^2+3^2=4^2

(4+9.....16)?

And 4+9=13, which does not equal 16. So No, because the given numbers satisfy the equation a^2+b^2=c^2 is correct.

Answer:

c = 35

Step-by-step explanation:

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

[tex]c^{2} = 21^{2} + 28^{2}[/tex]

[tex]c^{2} = 1225[/tex]

[tex]\sqrt{c^{2} } = \sqrt{1225}[/tex]

[tex]c = 35[/tex]

Given:

The function is

[tex]f(x)=2x^3+kx-9[/tex]

The remainder when f(x) is divided by x−2 is 23.

To find:

The value of k.

Solution:

According to the remainder theorem, if a polynomial P(x) is divided by (x-c), then the remainder is P(c).

It is given that, the remainder when f(x) is divided by x−2 is 23. By using remainder theorem, we get

[tex]f(2)=23[/tex]       ...(i)

Put x=2, to find the value of f(2).

[tex]f(2)=2(2)^3+k(2)-9[/tex]

[tex]f(2)=2(8)+2k-9[/tex]

[tex]f(2)=16+2k-9[/tex]

[tex]f(2)=2k+7[/tex]          ...(ii)

Using (i) and (ii), we get

[tex]2k+7=23[/tex]

[tex]2k=23-7[/tex]

[tex]k=\dfrac{16}{2}[/tex]

[tex]k=8[/tex]

Therefore, the value of k is 8.
