True or false: If two triangles have two pairs of corresponding angles congruent, along with a pair of non-included sides congruent, then the triangles are always congruent

Answers

it’s false i believe.

If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. If two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.

Therefore, it is true.

Which of these units would be best to measure the length of our classroom?

1. meters
2. centimeters
3. liters
4. kilometers
5. millimeters

Answers

Answer:

1. meters

Step-by-step explanation:

The smallest unit given in the choice is millimeters. Then comes the centimeters, then meters,  and the kilometers.

Liters is used to measure the volume of a liquid. For example we get 1 liters of milk but not 1 kilometers of milk.

The kilometers has a 1000 meters and

1m= 100 cm

1cm = 10mm

The kilometers is quite a large space and usually long distances such as length between 2 towns is measured in kilometers.

The area of the room or length is usually measured in feet but since feet is not given here.

1 feet = 0.3048 m

so the most suitable selection would be meters.

The millimeters is very small. 1 cm has 10 mm. A foot consists of 30.48 cm.

So meters is used.

Answers

Answer:

r = 0.1

Step-by-step explanation:

Constant proportionality or slope(rate of change) is found by Y divided by X.

1.4(y) ÷ 14(x) = 0.1(slope)

1.6(y) ÷ 16(x) = 0.1(slope)

2.1(y) ÷ 21(x) = 0.1(slope)

Check Work:

14 x 0.1 = 1.4

16 x 0.1 = 1.6

21 x 0.1 = 2.1

Answer:

1/10.

Step-by-step explanation:

The proportionality equation is given to you: [tex]y = rx[/tex]

Next, plug in the given [tex]x[/tex] and [tex]y[/tex] variables into the equation:

When: [tex]x = 14[/tex] & [tex]y = 1.4[/tex]

[tex]1.4 = r(14)\\1.4 = 14r\\(1.4)/14 = (14r)/14\\1.4/14 = r\\r = 0.1[/tex]

When: [tex]x = 16[/tex] & [tex]y = 1.6[/tex]

[tex]1.6 = r(16)\\1.6 = 16r\\(1.6)/16 = (16r)/16\\r = 1.6/16\\r = 0.1[/tex]

When: [tex]x = 21[/tex] & [tex]y = 2.1[/tex]

[tex]2.1 = r(21)\\[/tex]

[tex]21r = 2.1\\(21r)/21 = (2.1)/21\\r = 2.1/21\\r = 0.1[/tex]

r = 0.1 in all of the given, ∴ 0.1 is your answer. Change the decimal into a fraction:

0.1 = 1/10

1/10 is your answer.

Answers

Answer:

You subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees C. For decreases in temperature, the result is negative.

Have a nice Day , Hope this helped you I would appreciate it if you could mark my answer brainliest

Answer:

No, you are correct for the first one. The meaning of the point (4, 22) is that Magi took 22 minutes to run 4 miles.

(4, 22) is written as (x, y) where x is the number of miles Magi ran and y is the number of minutes Magi took.

Thus, when Magi ran 4 miles, she took 22 minutes.

A rectangular page is to contain 36 square inches of print. The margins on each side are 1 inch. Find the dimensions of the page such that the least amount of paper is used.

Answers

Given :

A rectangular page is to contain 36 square inches of print.

The margins on each side are 1 inch.

To Find :

The dimensions of the page such that the least amount of paper is used.

Solution :

Let, length and breadth of paper are x and y respectively.

Area is given by :

Area = xy    ....1)

xy = 36 inch²

Now, it is given than the margins on each side is 1 inch.

So, area of paper is :

A = ( x + 2 )( y + 2 )

We want area to be minimum.

Putting value of x from 1 , we get :

A = ( 36/y + 2 )( y + 2 )

Now, differentiating above equation and equating with 0 :

[tex]3 - \dfrac{108}{y^2}=0\\\\y = \pm 6[/tex]

Now, we know dimension cannot be negative.

So, y = 6 and x = 6 .

Therefore, length and breadth are 6 and 6 inch respectively.

The length are breadth is x = 6 and y = 6 inch respectively.

Given;

Each rectangular page is to contain 36 square inches of print.

The margins on each side are 1 inch.

We have to find ;

The dimensions of the page such that the least amount of paper is used.

 Therefore,

Let, length and breadth of paper are x and y respectively.

Area is given by :

Area = xy    

xy = 36 inch²

Now, it is given than the margins on each side is 1 inch.

So, Area of paper is :  A = ( x + 2 )( y + 2 )

We want area to be minimum.

Putting value of x from 1 , we get :

A = ( [tex]\frac{36}{y}[/tex] + 2 )( y + 2 )

Now, Differentiating above equation and equating with 0 :

[tex]3 -\frac{108}{y^{2} } = 0[/tex]

[tex]\frac{3y^{2} - 108 }{y^{2} } = 0[/tex]

[tex]3y^{2} - 108 = 0 \\3y^{2} = 108\\y^{2} = \frac{108}{3} \\y^{2} = 36\\y = 6[/tex]

then;  xy = 36

        6x = 36

         x =[tex]\frac{36}{6}[/tex]  

         x = 6inches

Now, we know dimension cannot be negative.

So, y = 6 and x = 6 .

Therefore, length and breadth are 6 and 6 inch respectively.

What is the x-value in the solution to this system of linear equations?

2x − y = 11

x + 3y = −5

−3
−1
2
4

Answers

Answer:

(7, -3)

Step-by-step explanation:

Solve the system of linear equations

2x − y = 11

x + 3y = −5

by elimination by addition and subtraction.  Multiply the second equation by -2, obtaining

2x - y = 11

-2x - 6y = 10

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

     -7y = 21, which yields y = -3

Knowing that y = -3, we can now find the value of x.  Let's use the first equation for this purpose.  Substituting -3 for y, we get:

2x - (-3) = 11, or

2x = 11 + 3, or 2x = 14.  Thus, x = 7.

The solution is (7, -3).

-3

Evaluate the expression 2n - 6 if n = 16.

Answers

Answer:

[tex]26[/tex]

Step-by-step explanation:

[tex]2n-6[/tex]

Given that:

[tex]n=16[/tex]

To evaluate the expression, we must simply substitute the given value of [tex]n[/tex], which is [tex]16[/tex], for [tex]n[/tex]:

[tex]2(16)-6[/tex]

Multiply:

[tex]32-6[/tex]

Subtract:

[tex]26[/tex]

-

To check your work, simply set the given expression equal to our solution, [tex]26[/tex]:

[tex]2n-6=26[/tex]

Add [tex]6[/tex] to both sides of the equation:

[tex]2n=32[/tex]

Divide both sides of the equation by the coefficient of [tex]n[/tex], which is [tex]2[/tex]:

[tex]n=16[/tex]

Since it matches the given value of [tex]n[/tex], our solution is correct!

Answer:

26

Step-by-step explanation:

This is the answer because:

1) First, we have to substitue the value that stand for n into the equation:

2(16) - 6

2) Next, we have to follow the order of operations in order to find the answer:

1. 2 x 16 = 32

2. 32 - 6 = 26

Therefore, the answer is 26.

Hope this helps! :D
