Suppose the cost per ton y to build an oil platform of x thousand tons is approximately by:What is the cost per ton for x=300?

The equation of the line which passes through points (-3,-4) and (3,2) is y = (2/3)x - 2.

The data in the given question is-

The passing points are-

(x1, y1) =(-3,-4) and

(x2, y2) =  (3,2)

Slope = m = (y2 - y1)/(x2 - x1)

m = (2 + 4)/(3 + 3)

m = 6/9

m = 2/3

Equation of the line is evaluated using slope intercept form.

y - y1 = m (x - x1)

y + 4 = (2/3)(x + 3)

y = (2/3)x - 2

Thus, the equation of the line which passes through points (-3,-4) and (3,2) is y = (2/3)x - 2.

We will have that Absolute Value is the magnitude of a value and is denotated as follows:

| x | : The absolute value of x.

When we speak about magnitude we refer just to possitive values. For example:

*The absolute value of 3:

| 3 | = 3

*The absolute value of -45:

| -45 | = 45

From this, we can clearly see that we "keep the number" but not the sign.

Since the situation forms a right triangle, we can apply trigonometric functions:

Tan a = opposite side/ adjacent side

Where:

a= angle = 22.3°

opposite side = x

adjacent side = 118

Replacing:

Tan 22.3° = x / 118

Solve for x

Tan 22.3 * 118 = x

x = 48.4 ft

The solution for the equation would be (-4,-16) as the definition of solution of equation says "A number that can be entered for the variable to produce a true number statement is the solution to an equation".

A number that can be entered for the variable to produce a true number statement is the solution to an equation. One-step equations can be solved in four different ways: by adding, subtracting, multiplying, and dividing. In an equation, both sides will remain equal if we add the same amount to each side. Systems of equations can be solved using one of three techniques: graphing, substitution, or elimination. Simply plot the given equations on a graph and locate the point(s) where they all intersect to solve a system by graphing. You can find the values of the variables you are solving for by finding the coordinate of this point.

The equation is,

y=4x

x+y=-20

x+4x=-20

5x=-20

x=-4

y=-4*4

y=-16

(x,y)=(-4,-16)

According to the definition of solution of equation, "A number that can be entered for the variable to produce a true number statement is the solution to an equation," the answer to the equation would be (-4,-16).

Principal = 9000

Interest rate = 7% = 0.07

Time = 5 years

Simple interest formula:

A = P(1 + rt)

In this case:

A = 9000(1 + 0.07*5) = 9000(1 + 0.35) = 9000(1.35) = 12150

Interest = A - P = 12150 - 9000 = 3

Answer:

F(t) = -0.54(t - 12)² + 104

Explanation:

We know that C(t) = -0.30(t - 12)² + 40 and F(t) = 9/5C(t) + 32

Then, we can replace C(t) on the equation of F(t) to get

Therefore, the new function F(t) is

F(t) = -0.54(t - 12)² + 104

Answer:

x = 1 , x = 13

Step-by-step explanation:

(x - 7)² = 36 ( take square root of both sides )

x - 7 = ± [tex]\sqrt{36}[/tex] = ± 6 ( add 7 to both sides )

x = 7 ± 6

then

x = 7 - 6 = 1

x = 7 + 6 = 13

By definition, when two figures are similar, their corresponding angles are congruent (this means that they have equal measure) and the ratios of the lengths of their corresponding sides are the same.

In this case you know that the triangles shown in the picture are similar, therefore, you can set up the following proportion:

You can identify that:

Therefore, you can substitute values into the proportion:

Now you have to solve for ST:

The answer is:

The amount of sand = 200 kg

The amount of gravel = 600 kg

The amount of cement = 1000 kg

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

Dry concrete can be made by mixing sand, gravel and cement into the ratio 1 : 3 : 5.

And, They want 1800 kg of dry concrete.

Now,

Since, Dry concrete can be made by mixing sand, gravel and cement into the ratio 1 : 3 : 5.

So, We can formulate;

The amount of sand = x

The amount of gravel = 3x

The amount of cement = 5x

Hence, We get;

⇒ x + 3x + 5x = 1800

Solve for x as;

⇒ x + 3x + 5x = 1800

⇒ 9x = 1800

⇒ x = 1800/9

⇒ x = 200

Thus, The amount of sand = x = 200 kg

The amount of gravel = 3x = 3 × 200 kg

                                          = 600 kg

The amount of cement = 5x = 5 × 200 kg

                                            = 1000 kg

Therefore, We get;

The amount of sand = 200 kg

The amount of gravel = 600 kg

The amount of cement = 1000 kg

Answer:

Step-by-step explanation:

There is a property of angle of triangles.

Exterior angle = Sum of opposite interior angles

7x + 8 = 3x - 9 + 61

7x + 8 = 3x + 52

7x - 3x = 52 - 8

4x = 44

x = 44/4

x = 11

m∠WHG = 7x + 8

               = 7 ( 11 ) + 8

               = 77 + 8

m∠WHG = 85

Answer:

Angle WHG is 85 degrees.

Step-by-step explanation:

X = 11.

7(11) + 8 = 85.

180 - 85 = 95 (Angle FHG.)
3(11) - 9 = 24 (Angle GFH.)
A triangle's angles always add up to 180 degrees.

24 + 95 + 61 = 180.
To double check, 180 - 95 = 85 degrees.

I hope this helped! And as for finding X, I kind of forgot how to get X, so I tried X being number 5-10 first, then tried 11, and it worked. Sorry for the late response.

The area of a rectangle is the product of its length and breadth. The maximum area enclosed by the fence is 36800 square meter  and the dimensions of the enclosed area are 115 meter and 320 meter. The width is given as 115 meter.

A rectangle is a type of parallelogram that has equal diagonals.

All the interior angles of a rectangle are equal to the right angle.

The diagonals of a rectangle do not bisect each other.

The dimensions of the given rectangle are (650 - 2x) and x.

Then, the area of the given rectangle can be written in terms of x as

A(x)  = x(650 - 2x)

In order to find the maximum area enclosed take the derivative of A(x) and equate it to zero as follows,

(660 - 2x) - 2x = 0

=> 4x = 660

=> x = 660 / 4

=> x = 115

Now, the maximum area is the value of A(x) at x = 115 as below,

= 115 × (650 - 2×115)

= 115 × 320

= 36800

The dimensions for the maximum area are 115 and (650 - 2 × 115) = 320.

Hence, the largest area enclosed is 36800 square meter and the dimensions of the enclosed area are 115 meter and 320 meter. The width is given as 115 meter.

The image shows the square root of 41

The root of 41 in decimal is 6.403.

As such the integers before and after 6.403 are 6 and 7

Another way to solve this is to consider the perfect square before 41 which is 36.

The square root of 36 is 6. Since 41 is higher than 36, the number before root 41 would be 6 and the next number after 6 is 7.
