Answer

<F = 105°

<G = 41°

<J = 34°

GJ = 19m

JH =14m

GH = 16m

Step-by-step explanation:

Since triangle DEF is congruent to triangle GJH, the following are true

<D = <G

<E = <J

<F = <H

Given

<H = 105°

Hence <F = 105°

Also <E = 34° =<J

From ∆GHJ

<G+<H+<J = 180°

<G+105+34 = 180°

<G + 139 =180

<G= 180-139

<G = 41°

Get the sides. For the sides, the following are true

DE = GJ = 19m

Also EF =JH = 14m

DF =GH = 16m

Answer:

[tex]\left(3x^2\right)\left(5x^8\right)\left(6x^5\right)=90x^{15}[/tex]                  

Step-by-step explanation:

Given the expression

[tex]\left(3x^2\right)\left(5x^8\right)\left(6x^5\right)[/tex]

Apply the exponent rule:

[tex]a^b\cdot \:a^c=a^{b+c}[/tex]

so the expression becomes

[tex]\left(3x^2\right)\:\left(5x^8\right)\:\left(6x^5\right)=3\cdot \:\:5\cdot \:\:6x^{2+8+5}[/tex]

Add the exponent numbers: 2+8+5=15

                             [tex]=3\cdot \:5\cdot \:6x^{15}[/tex]

Multiply the numbers: 3×5×6=90

                             [tex]=90x^{15}[/tex]

Therefore, we conclude that:

[tex]\left(3x^2\right)\left(5x^8\right)\left(6x^5\right)=90x^{15}[/tex]

Where the above right triangle is given, note that the value of x when rounded to the nearest tenth is 19.2.

A right triangle is a triangle with one angle measuring 90°, forming a perpendicular side.

In this case,the base is 9 and the height is   17. Using   the Pythagorean theorem, we can calculate the length   of the hypotenuse as follows:

x² = 9² + 17²

x²= 81 + 289

x² = 370

To find the value of x, we take the square root of both sides  -

x = √370

x = 19.2353840617

x ≈ 19.2 (rounded to the nearest tenth)

Step-by-step explanation:

1) lets use elimination to solve this:

multiply 10x+4y=24 with 3 in order to get "4y" into "12y"

3(10x+4y=24)

30x+12y=72

now subtract both equations to eliminate 'y"

30x+12y=72

-

6x+12y=48

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

24x=24

x=1

now substitute 1 in the above equation:

The correct graph for the given inequality is the 2nd one.

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.

Given that,

Max correctly solved the inequality and a ≤ -50.

The solution set is all real numbers less than or equal to -50.

Since -50 is inclusive, we draw a closed circle on -50 on the number line and draw the arrow to the left.

Hence, the correct graph is the 2nd one.

Answer:

65 miles per hour.

Step-by-step explanation:

To find the unit rate, we need to figure out how far we travel in one hour.

325/5 = 65/1

We travel 65 miles in one hour.

Answer:

65 mph (miles per hour)

Step-by-step explanation:

Because unit rate is a rate where the second quantity is one unit.

And to find miles per hour in this equation you have to divide 325 miles by 5 (because it is 5 hours) and you get 65.

To apply the following rule to the point (-5,6): (x,y)-->(y, -x).

Coordinate, is represented as the values on the x-axis and y-axis of the graph

Translation of a point is defined as changing the location of the point on an arbitrary space with the help of any function and instructions.

Here,
In the question, a rule is mentioned for the transposition of the coordinates,
(x,y)-->(y,-x)
we just need to simply poor the coordinate in the given translation equation,

Answer:

It is an arithmetic sequence

Common difference is -4

Step-by-step explanation:

Here, we want to determine the type of sequence

As we can see, the difference between each of the terms is as follows;

13-17 = 9-13 = -4

What this mean is that we have a constant common difference

This simply shows that the sequence we have is an arithmetic sequence

The common difference is thus;

13-17 = 9-13 = -4

Using the Pythagorean Theorem, it is found that he would travel 92 miles farther by  walking from his home to his friend's house and then from  his friend's house to work than he would travel by walking  from his home directly to work.

The Pythagorean Theorem states that, on a right triangle, the length of the hypotenuse squared is the sum of the length of each leg squared, that is:

[tex]h^2 = l_1^2 + l_2^2[/tex]

Walking from his home to his friend's house and then from  his friend's house to work, Jardon travels 240 + 120 = 360 yards.

Directly from his home to work, the distance is the hypotenuse of a right triangle with legs [tex]l_1 = 240, l_2 = 120[/tex], hence:

[tex]d^2 = 240^2 + 120^2[/tex]

[tex]d = \sqrt{240^2 + 120^2}[/tex]

[tex]d = 268[/tex]

360 - 268 = 92

He would travel 92 miles farther by  walking from his home to his friend's house and then from  his friend's house to work than he would travel by walking  from his home directly to work.

Answer:

The x coordinate of the solution to the system of equations is 8

Step-by-step explanation:

We need to find the x coordinate of the solution to the system of equations?

[tex]x- 5y =23\\-2x - 6y =2[/tex]

Let

[tex]x- 5y =23--eq(1)\\-2x - 6y =2--eq(2)[/tex]

Multiply equation 1 with 2 and add both equations

[tex]2x- 10y =46\\-2x - 6y =2\\-------\\-16y=48\\y=\frac{48}{-16}\\y=-3[/tex]

So, we get the value of y = -3

Now, for finding x, put value of y in equation 1

[tex]x- 5y =23Put\:y=-3\\x-5(-3)=23\\x+15=23\\x=23-15\\x=8[/tex]

So, we get x = 8

The solution set is (8,-3)

So, the x coordinate of the solution to the system of equations is 8
