Answer:

The intersection point of the two curves is [tex](x,y) = \left(\frac{3}{2}\,kton.m, 185\,USD \right)[/tex].

Step-by-step explanation:

From statement we get the following equations:

Supply curve

[tex]90\cdot x - y = -50[/tex] (1)

Demand curve

[tex]10\cdot x + y = 200[/tex] (2)

Where:

[tex]x[/tex] - Quantity, measured in thousands of metric tons.

[tex]y[/tex] - Price, measured in US dollars per metric tons.

If we add both equations, then we find that quantity is:

[tex](90\cdot x -y )+(10\cdot x +y) = -50+200[/tex]

[tex]100\cdot x = 150[/tex]

[tex]x = \frac{3}{2}\,kton.m[/tex]

Then, we finally find the price by substituting on (2):

[tex]y = 200-10\cdot \left(\frac{3}{2} \right)[/tex]

[tex]y = 200-15[/tex]

[tex]y = 185\,USD[/tex]

The intersection point of the two curves is [tex](x,y) = \left(\frac{3}{2}\,kton.m, 185\,USD \right)[/tex].

Answer:

B. 25%

Step-by-step explanation:

You turn the 25% into a decimal so it would be .25 then you multiply by 60. After that you subtract the answer you have by 60.

Step-by-step explanation:

The formula for calculating the area of a square is expressed as;

A = x² where;

x is the length of one side of the square

Given

x = 10in

A = 10²

A = 10 * 10

A = 100in²

Area of the square with side length 10in is 100in²

From the equation A = x², we can see that as the value of x increases, the value of the area also increases and vice versa. This means that the area of the square is directky proportional to its length. Hence we can say YES, the area of a square and the length of its side directly proportional

Answer:

100 sq in

Step-by-step explanation:

No, not proportional

Answer:

x=5

Step-by-step explanation:

I first subtracted 88 from 180 because we know that 180 is the total degree of the three angles in a trangle. I got 92, then divided that by 2 since there are two angles that are unknown. I got 46, which I can then use to form the equation (9x+1)=46. I subtracted 1 from both sides to get rid of the 1 (since we're finding what x equals to), I then got 9x=45. After that, I divided 9 from both sides and got the answer x=5.

Answer:

Step-by-step explanation:

Step one:

given data

perimeter= 510 yards

let the width be x, width=x

length= (4x-5)-----quadruple mean 4 times

Step two:

the expression for perimeter is

P=2L+2W

510=2(4x-5)+2x

510=8x-10+2x

510+10=8x+2x

520=10x

divide both sides by 10

x=520/10

x=52

the width is 52 yards

the lenght is  (4x-5)

L=4(52)-5

L=208-5

L=203 yards

Answer:

y=40

Step-by-step explanation:

x   y

9   15

24  y

9/24=15/y

24*15=9y

360=9y

40=y

Therefore, 40 is correct.

If x and y are proportional, when x=24 we get y=40. Therefore, option (3) is the correct answer.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

Given that, in a proportional relationship when x=9 we know that y=15.

If x is directly varies to y we get

x∝y

x=ky

Now, 9=15k

k=9/15

k=3/5

So, equation is x=3/5y

When x=24, we get

24=3/5y

24×5=3y

y=40

Therefore, option (3) is the correct answer.

6x + 18y = 18. Let us take x = 0

6(0) + 18y = 18

0 + 18y = 18

18y = 18

y = 18/18

y = 1

(0, 1) [x = 0, y = 1]

6x + 18y = 18. Let us take y = 0

6x + 18(0) = 18

6x + 0 = 18

6x = 18

x = 18/6

Step-by-step explanation:

h= 55/12 if thats what u askin for

5h – 15 + 7h = 40

value of h

[tex]:\implies \bold{5h – 15 + 7h = 40}[/tex]

[tex] :\implies \bold{5h + 7h = 40 + 15}[/tex]

Answer:

Step-by-step explanation:

Given that segment BC is the base of the triangle, this drawing shows that triangle ABC is an equilateral triangle.

Since;

<B = <C = 60°

Then,

<A + <B + <C = [tex]180^{o}[/tex]

<A + 60° + 60° = [tex]180^{o}[/tex]

<A = [tex]180^{o}[/tex] - [tex]120^{o}[/tex]

    = 60°

Thus,

AB = BC = AC = 6 inches

Answer:

Triangles 3 and 4 are both isosceles. They each have a 60 degree angle.

This is a similar triangle.

Step-by-step explanation:

Isosceles triangle is one in which two sides are equal.

Similar triangles are triangles which have all corresponding angles equal and which have corresponding sides with the same ratio.

Now the given isosceles triangle both have all three angles equal to 60 degrees which makes them similar triangles.

The other choices given are not similar triangles because

1) they do not have all corresponding angles equal

2) their lengths are unknown and cannot be assumed to be in ratio.

Step-by-step explanation:

2 ² is 4. If you add 2 to 4, you get 6. Therefore, the answer is 2.

Solving using factorization method, the unknown number is either -3 or 2.

The square of a number is the product win a number is multiplied by itself.

Let the unknown number be a.

Square of a = a × a

The number is added to its square:

[tex]a + a^{2}= 6[/tex]

[tex]a^{2} \: + a - 6 = 0[/tex]

x        - the first integer

x+1   - the next integer consecutive to x (the second consecutive integer)

x + x+1    - the sum of two consecutive integers

x+1+1=x+2 - the integer consecutive to x+1 (the third consecutive integer)

x+2 + 2  - two more than the third integer

x + x+1  = x+2 + 2

2x + 1 = x + 4

x + 1 = 4
