The mass of 7m chain = 7 x 2.16 kg = 15.12 kg

It says that 7m of grade 70 tow chain which has a diameter of 3/8'' is required to tow a car.

So length of the chain = 7m

Now given that the weight of the chain = 2.16kg/m

That is weight of 1m of chain = 2.16 kg = mass of 1m of chain

Here, weight corresponds to the mass itself, since both has the same unit 'kilograms(kg)'.

So to find the mass of 7m chain, we need to multiply mass of 1m chain to the length of the chain.

Thus, the mass of 7m chain = 7 x 2.16 kg = 15.12 kg

The two triangles are congruent because each transformation is a rigid motion. Therefore, option B is the correct answer.

Given that, triangle ABC is reflected in the x-axis, rotated 180°, and translated 2 units to the right and 4 units down to form triangle XYZ.

Reflection is flipping an object across a line without changing its size or shape. Rotation is rotating an object about a fixed point without changing its size or shape. The translation is sliding a figure in any direction without changing its size, shape or orientation.

We know that reflection, rotation and translation in the vertical or horizontal direction are rigid motions.

Rigid motions do not change the size of a polygon so that the two polygons are congruent.

The two triangles are congruent because each transformation is a rigid motion. Therefore, option B is the correct answer.

My possible absolute value is -3 ≤ lx - 2l ≤ 3

What is Absolute Value?

The absolute value (or modulus) l x l of a real number x is the non - negative value of x without regard to its sign. For example, the absolute value of 5 is 5 , and the absolute value of -5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.

Now, the question is:

what is a possible absolute value inequality to represent -1≤x≤5

The representation of inequality -1≤x≤5 of  absolute value will be :

-3 ≤ lx - 2l ≤ 3

Now, add 2 to each segment of the system of inequalities to solve for x while keeping the equation  balanced:

-3 + 2 ≤ x -2 + 2 ≤ 3+2

-1 ≤ x ≤ 5

The exact trigonometric ratios for the angle x is second quadrant.

Given Radian equals to θ = 27π / 4, we need to find all the Trigonometric ratios for the same -

Lets calculate the value of θ first.

We know π equals 180 degree angle and 2π equals 360 degree, hence with each 2π the radian moves back to zero degree. Which means

θ = 27π / 4 can be reduced to θ = 3π / 4

Hence θ = 135 degree which can be represented as below -

As This lies in second quadrant, hence  on x-axis (Value of base , needs to be taken as -1)

sin θ = 1/√2                            cosec θ = √2

cos θ = -1/√2                          sec θ = - √2

tan θ = -1                               cot θ = - 1

Trigonometric ratios are based on the value of the ratio of sides of a right-angled triangle and contain the values of all trigonometric functions. The trigonometric ratios of a given acute angle are the ratios of the sides of a right-angled triangle with respect to that angle.

All the given options are correct

The variation expression is given as

(2x + 3y) ∝ (x + 5y)

Rewrite as an equation

So, we have

(2x + 3y) = k(x + 5y)

Remove the brackets

So, we have

2x + 3y = kx + 5ky

Collect the like terms

So, we have

kx - 2x = 3y - 5ky

This gives

x(k - 2) = y(3 - 5k)

Divide by both sides by y(k - 2)

x/y = (5k - 3)/(2 - k) --- option (a)

Multiply both sides by y

x = y(5k - 3)/(2 - k) --- option (b)

To solve for x, the equation -fx -g = h is correctly rewritten as x = -h/f - g/f.

An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.

Given the equation in the question;

-fx - g = h

Solve for x.

To solve for x simply means to make x the subject of the formula or equation.

-fx - g = h

Add g to both side

-fx - g + g = h + g

Negative g and positive g cancels out.

-fx = h + g

Now, divide each term in the equation by the coefficient of x

-fx/-f = h/-f + g/-f

x = -h/f + (-g/f)

x = -h/f - g/f

Therefore, to solve for x, the equation -fx -g = h is correctly rewritten as x = -h/f - g/f.

Step-by-step explanation:

3x-15 = 2x+7

-2x         -2x

x-15 = 7

+15     +15

x = 22

180-51 = 129

y+16 = 129

-16       -16

y = 113

Answer:

x = 22

y = 113

Step-by-step explanation:

The angles marked as (2x+7) and (3x-15) are vertical angles, and therefore are equal to each other.

2x + 7 = 3x - 15 simplifying:

7 = x - 15

22 = x

Angles marked as (3x-15) and (y+16) form a linear pair and are therefore supplimetery. Now that we know the value of x, we can set up the following equation.

3(22) - 15 + y + 16 = 180 simplifying:

66 - 15 + y + 16 = 180

66 + y + 16 = 195

y = 113

Answer:

y = -3

Step-by-step explanation:

We are given an equation of the line, x=9.

And we want to write another equation of the line that is perpendicular to x=9 and passes through (-6, -3).

There are 3 ways to write the equation of the line:

Any one of these forms would work, but let's use slope-intercept form, as it is the most common way to write the equation of the line.

Perpendicular lines have slopes that multiply to get -1. They are also considered negative and reciprocal. For example, 5 and -1/5 would be the slopes of perpendicular lines.

So, let's find the slope of x=9.

If a line is written like x=9, it means that when it is graphed, it will be a vertical line, and a vertical line has an undefined slope.

As you may know, [tex]\frac{1}{0}[/tex] is also considered to be undefined. This means that the slope of this vertical line can be written as [tex]\frac{1}{0}[/tex].

Now, let's get the reciprocal of this slope (put the value of the numerator on the denominator and vice versa), then add a minus sign after it.

[tex]\frac{1}{0}[/tex] => [tex]-\frac{0}{1}[/tex] => 0

The slope of the line we're writing is 0.

We can replace m in y=mx+b with 0.

y = 0x + b

Now we need to find b.

As the equation passes through the point (-6,-3), we can use its values to help solve for b.

Substitute -6 as x and -3 as y in the equation.

-3 = 0(-6) + b

Multiply.

-3 = b

Replace b with -3 in the equation.

y = 0x - 3

This can also be written as:

y = -3
