Answer:

If two things are equivalent, they are the same. Equivalent expressions are expressions that are the same, even though they may look a little different. If you plug in the same variable value into equivalent expressions, they will each give you the same value when you simplify.

Answer:

Since its a right triangle you automatically know the C is 90 degrees. And since all triangle have to add up to 180 degrees, you know B has to equal 40 degrees.

A= 50

B= 40

C= 90

B + C

40 + 90

BC = 130 degrees

Answer:  72

Step-by-step explanation:    so you do a line = line method the lines should look like they are fractions.  

you do it for the both numbers the percent is always out of 100.

it should look like this

40%            ?

--------- = -----------    

100%       180

then you cross multiply 40 and 180 and than divide it by 100.   your answer should be 72.    you later replace the ? with 72

you know this because It is smaller than 180 and its bigger than the number 40.

The number pages left to read is 12 pages.

Given that, George still has 40 percent of his book to read.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Let the total number of pages be x.

Now, x-40% of x=180

⇒ x-0.4x=180

⇒ 0.6x=180

⇒ x=180/0.6

⇒ x=300

So, remaining pages = 300-180=120

Therefore, the number pages left to read is 12 pages.

Answer:

170

Step-by-step explanation:

20 + (26 - 1)6

= 20 + (25)6

= 20 + 150

= 170

The 26th term in the arithmetic sequence: 20, 26, 32, 38, ... is 170

Given:

20, 26, 32, 38, ...

nth term = a + (n - 1) d

where,

20, 26, 32, 38, ...

a = 20

d = 26 - 20

= 6

= 20 + (26 - 1) 6

= 20 + (25) 6

= 20 + 150

= 170

Therefore, the 26th term in the arithmetic sequence is 170

Answer:

y=45

x=90

Step-by-step explanation:

x is a right angle, y is vertical from 45 degrees making it congruent to it.

Answer:

C: x=90 y=45

Step-by-step explanation:

The place where x is is obviously a right angle therefore, it is 90. Then here is a diagonal line cutting through the 90 degrees in half. 90/2=45.

Step-by-step explanation:

Answer:

25^2=625

24^2= 576

7^2= 49

as 625 = 576+49 so 7,24,25 form a Pythagorean triplet

similarly

9,40,41 also is a Pythagorean triplet

Answer:

x = 5

y = 3

Step-by-step explanation:

9x and 45 are alternate interior angles, meaning they're congruent, so set them equal to one another, like so:

9x = 45

Divide both sides by 9:

x = 5

Solving for y, the two sides are of equal length, so set them equal:

6y = 18

Divide both sides by 6:

y = 3

Step-by-step explanation:

By alternate interior angle

9x=45°

x=5°

All parallel sides are equal in parallelogram

6y=18

Answer:

The perimeter of rectangle ABCD = 16 units

Step-by-step explanation:

The vertices of the rectangle: A(−2,1), B(3, 1), C(3,4), and D(−2,4).

AB is horizontal, so measre the difference between the x coordinates of A and B.

between -2 and 3 are 5 units.

BC is vertical, so measre the difference between the y coordinates of B and C.

between 4 and 1 is 3 units.

The perimeter = 2 * ( AB + BC )

Substitute AB = 5 and CD = 3

2 * ( 5 + 3 )

2 * 8

The perimeter of rectangle ABCD = 16 units

Answer:

16 units

Step-by-step explanation:

finding the lengths of all sides which are 5,5,3, and 3 then adding them will get you 16 units.

Answer:

81 has the most factors of 3

Step-by-step explanation:

To conclude which of the following options has the most factors of 3, take each of the number's prime factorization, which will help us solve the problem.

( 1 ) 81 is a composite number and is 9 squared. Knowing that 3 squared = 9, we can say that the prime factorization of 81 = 3 [tex]*[/tex] 3 [tex]*[/tex] 3 [tex]*[/tex] 3, which can also be denoted as 3⁴.

( 2 ) 270 is a composite number. The exponents in the prime factorization are 1, 3, and 1, and therefore it's prime factorization is - 3 [tex]*[/tex] 5 [tex]*[/tex] 3 [tex]*[/tex] 2 [tex]*[/tex] 3, composed of 3 3s.

( 3 ) If we put all of it together we have the factors 3 x 3 x 3 x 37 = 999. It can also be written in exponential form, with 3 to the power of 3 - hence having 3 factors of 3.

And finally the value 3333 has the prime factorization of 3 [tex]*[/tex] 11 [tex]*[/tex] 101, and as you can see it has 1 factor of 3. 81, having 4 factors of 3, is present with the most factors, and therefore is our solution.

Number 81 has the most number of factor 3. Option A is correct.

A number from the options to be determined that has the most number of factor 3.

factors can be defined by splitting the value into multipliable values.

Here,
Factors of 81 = 3,3,3,3            Number of factor 3 = 4
Factors of 270 =2,3,3,3,5       Number of factor 3 = 3  
Factors of 999 =3,3,11             Number of factor 3 = 2
Factors of 3333 = 3,11             Number of factor 3 = 1
As per the above comparison, 81 has the most number of factor 3.

Thus, Number 81 has the most number of factors 3.
