Answer:
3 that is the cool answer
if you insist 3 * 3.14 = 9.42
Step-by-step explanation:
the circumference of a circle calculation is 2
your circle r = 27, so circumference = 54
~~~~~~~~~~~~~~~~~~~~~
a circle has 360°
you problem is 20 of the 360
or 20/360 = 2/36 = 1/18
~~~~~~~~~~~~~~~~
your solution is 1/18 * 54 = 3
A recurring decimal is one is which the numbers after the decimal keeps on repeating up till infinity, it does not terminate.
Now for 20/11: 11 into 20 is 1 remainder 9.
20 / 11 = 1 whole number, 9/11.
We can now perform 9/11 with our calculator = 0.818181.....
The ....... after the 81 signifies it continues in that pattern indefinitely.
Therefore 20/11 = 1 whole number, 9/11= 1 + 0.818181....
= 1.818181......
The different digits that appear are 1 and 8.
So 2 different digits appear when 20/11 is written as recurring decimal.
Answer:
36
Step-by-step explanation:
(7+ )(7- )
this is in the form of a^2-b^2 formula
a^2-d^2=(a-b)(a+b).so write,
(7)^2-( )^2
=49-13
=36
Given:
The two models for the two polynomials.
To find:
The sum of the given polynomials.
Solution:
From the given figure, it clear that
Adding both polynomials, we get
Therefore, the correct option is A.
Let
x--------> the number
we know that
x+(1/x)=65/28---------> x+1/x=65/28-----> multiply by x
x²+1=65/28*x-----> x²-(65/28)*x+1=0
using a graph tool----> to resolve the second order equation
see the attached figure
the solution is
x=1.75-----> 1 3/4----> (4*1+3)//4----> 7/4
so
7/4+4/7----> (7*7+4*4)/28----> (49+16)/28----> 65/28----> is correct
the answer isthe number is 7/4
