George still has 40 percent of his book to read. If George has read 180 pages, how many pages does he still have to read? How do you know?
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.
What is percentage?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.

57m = xh
19 = 1/2
57 = x
19x = 1/2 (57)
19x = 28.5

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(−2,1), B(3, 1), C(3,4), and D(−2,4).
What is the perimeter of rectangle ABCD?
_____units
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.

Find the 26th term in the arithmetic sequence: 20, 26, 32, 38, ...
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 of an arithmetic sequence is given bynth term = a + (n - 1) d
where,
a = first termd = common differencen = nth term20, 26, 32, 38, ...
a = 20
d = 26 - 20
= 6
26th term = a + (n - 1) d= 20 + (26 - 1) 6
= 20 + (25) 6
= 20 + 150
= 170
Therefore, the 26th term in the arithmetic sequence is 170

Carlotta collects stamps. She owns f stamps from France and 15 more than twice this amount of American stamps. Which expression represents the number of American stamps that Carlotta owns?
A: f•/•2-15
B: 2f-15
C: f•/•2+15
D: 2f+15
Answer:
D: 2f+15
Step-by-step explanation:
f is the number of stamps from France that Carlotta owns.
Twice this amount is 2f
Then, 15 more than twice this amount is 2f + 15, and this is the expression that represents the number of American stamps that Carlotta owns

of the following numbers, which has the most factors of 3?
a) 81
b) 270
c) 999
d) 3333
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.

m=2 Make sure to move the terms, then collect the like terms, then subtract, then divide both sides by 6
Answer:
m = 2.

Find the value of x and y
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
y=3

A circle has a radius of 5/3 units and is centered at (9.2 -7.4)
Write the equation of the Circle.
Answer:
(x - 9.2)^2 + (y + 7.4)^2 = (5/3)^2
Step-by-step explanation:
We start with (x - h)^2 + (y - k)^2 = r^2. The center is (h, k) and the radius is r.
Then we have:
(x - 9.2)^2 + (y + 7.4)^2 = (5/3)^2
