1000 * 0.9 = 900

According to the given figure, option (A) and option (F) are correct options which better shows ∠4 ≅ ∠6 respectively.

Let's procced to solve this question.

∠4 ≅ ∠8 by the corresponding angle postulate because two parallel lines is cut by a transversal and ∠4 ≅ ∠8 by the corresponding angle postulate. It's true.

∠6 ≅ ∠8 by the definition of vertical angles. It's true.

and by using the transitive property of congruence that ∠A ≅ ∠B and ∠B  ≅ ∠C then ∠A ≅ ∠C.

⇒ ∠4 ≅ ∠6 by the transitive property of congruence.

Hence, option (A) is correct.

Now,

∠2 ≅ ∠6 by the corresponding angle postulate because two parallel lines is cut by a transversal and ∠2 ≅ ∠6 by the corresponding angle postulate. It's true.

∠2 ≅ ∠4 by the definition of vertical angles. It's true.

and by using the transitive property of congruence that ∠A ≅ ∠B and ∠B  ≅ ∠C then ∠A ≅ ∠C.

⇒ ∠4 ≅ ∠6 by the transitive property of congruence.

Hence, option (F) is correct.

Therefore, option (A) and option (F) are correct option.

If a 42-inch string is to be cut so that one piece is 7 inches longer than the other, then the shorter piece has a length of 17.5 inches

The length of the shorter piece can be determined by using an algebraic expression.

Any expression consisting of both numbers and letters is considered to be an algebraic expression.

Considering, x to be the length of the shorter piece

As the longer piece is 7 inches longer than the shorter piece, an algebraic expression can be given as,

x + (x + 7) = 42

x + x + 7 = 42

2x + 7 = 42

2x = 42 - 7

2x = 35

x = 35 ÷ 2

x = 17.5

Hence, the length of the shorter piece is calculated to be 17.5 inches.

Using the law of cosines, the measures of the angles are given as follows:

The law of cosines states that we can find one of the sides or the angle C of a triangle according to the following equation:

c² = a² + b² - 2abcos(C)

In which:

For this problem, the parameters for the triangle are given as follows:

a = b = 12, c = 3.

We want to solve for the smallest angle C, hence:

c² = a² + b² - 2abcos(C)

9 = 288 - 288cos(C)

288cos(C) = 279

cos(C) = 279/288

C = arccos(279/288)

C = 14.36º.

The other two angles are congruent, and the sum of the internal angles of a triangle is of 180º, hence:

14.36 + x + x = 180

2x = 165.64

x = 165.64/2

x = 82.82º.

Left-Skewed is the answer.

Histograms are a very common method of visualizing data, and that means that understanding how to interpret histograms is a valuable and important skill in virtually any career. There are a number of things to pay particular attention to when reading a histogram.

Bell-Shaped: A histogram with a prominent ‘mound’ in the center and similar tapering to the left and right. One indication of this shape is that the data is unimodal – meaning that the data has a single mode, identified by the ‘peak’ of the curve.

Uniform: A uniform-shaped histogram indicates data that is very consistent; the frequency of each class is very similar to that of the others.

Right-Skewed: A right-skewed histogram has a peak that is left of the center and a more gradual tapering to the right side of the graph.

Left-Skewed: A left-skewed histogram has a peak to the right of the center, more gradually tapering to the left side. It is unimodal, with the mode closer to the right and greater than either mean or median.

Undefined Bimodal: This shape is not specifically defined, but we can note regardless that it is bi-modal, having two separate classes or intervals equally representing the maximum frequency of the distribution.

If two quantities are proportional, the true statements about the graph showing the relationship between them are-

D. The points of the graph form a straight line.

E. The points of the graph must include the origin.

F. The points must all form equivalent ratios.

In mathematics, two sequences of numbers, often experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is called the coefficient of proportionality or proportionality constant.

Now let us suppose there are two quantities x and y.

A graph between two quantities is plotted.

Suppose x is directly proportional to y.

Thus, these Two variable quantities have a constant ratio

So, we can write

y ∝ x

Applying constant of proportionality,

y = kx

Where k is the constant of proportionality.

It represents a straight line.

Now,the value of x = 0 then the value of y must be equal zero, then the line which represented the direct variation must be passes through the origin

Now  If two variable quantities have a constant ratio and since y = kx is a straight line and passes through origin therefore from the given options the correct answer are-

D. The points of the graph form a straight line.

E. The points of the graph must include the origin.

F. The points must all form equivalent ratios.

Thus, If two quantities are proportional, the true statements about the graph showing the relationship between them are-

Answer:

[tex]y = \frac{3}{4}x - 8[/tex]

Step-by-step explanation:

We know that the slope of a line perpendicular to a line with a given slope is the negative reciprocal of that given slope.  We are given that we want a line perpendicular to that of 4x + 3y = 3.  To find the slope of this given line, we put it into slope intercept form y = mx + b where m is the slope:

[tex]4x + 3y = 3[/tex]

[tex]3y = 3 - 4x[/tex]

[tex]y = 1 - \frac{4}{3}x[/tex]

So we have that the slope of our given line is -4/3. The negative reciprocal of this is 3/4. We thus have that the slope of the line we are looking for is 3/4.

We then know that the equation of the line we want fits the form [tex]y=\frac{3}{4} x + b[/tex], which we know through point slope form. We are then given that (8, -2) is a point on this line. Plugging in:

[tex]-2 = \frac{3}{4}(8) + b[/tex]

[tex]-2 = 6 + b[/tex]

[tex]b = -8[/tex]

We then get the equation of the line we are looking for as [tex]y = \frac{3}{4}x - 8[/tex].

Answer:

equation: x-42=50

answer: x=8

Step-by-step explanation:

lets write the equation. We have 42 less than x is -50. 42 less than x could translate to x-42 and if it is 50, then that is what x-42 equals.

So we would have x-42=50

Now you can carry over the -42 to start solving

x-42=50

 +42    +42

(notice it is added on both sides. I add them to get rid of the -42 on the x side and whatever you do to one side you ALWAYS do to the other.)

x= 50-42

x= 8

Answer:

An equivalent expression for 4 times d raised to the negative third power all over quantity 22 times d raised to the ninth power is 2d⁻³/11d⁻⁹

What is an expression?

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

What is an exponent?

An exponent can be defined as a mathematical operation that is used to raise a quantity to the power of another and it is generally written as bⁿ.

Translating the word problem into an algebraic expression, we have;

4 times d raised to the negative third power = (4 × d)⁻³ = 4d⁻³

22 times d raised to the ninth power = (22 × d)⁻⁹ = 22d⁻⁹

Next, we would write the equation as a quotient:

Expression = 4d⁻³/22d⁻⁹

Expression = 2d⁻³/11d⁻⁹

After 12 seconds, the equipment elevator will be 204 feet under the ground while the miner's elevator will be 235 feet under the ground.

After 12 seconds, the miner's elevator is deeper.

It is the ratio of distance and time.

We have,

Equipment elevator:

Speed = 5 feet per sec

Miner's elevator:

Speed = 17 feet per sec

Now,

The position (distance) of the equipment elevator after 31 seconds and 12 seconds:

Distance = speed x time

Distance = Distance after 31 sec + Distance after 12 sec

= (31 x 5) + (16 x 5)

= 155 + 80

The position (distance) of the equipment elevator after 12 seconds:
