Answer: There are 1800 unique names from both the lists.
Explanation:
Since we have given that
there are two lists :
In First list, number of names = 1200
In Second list, number of names = 900
According to question , we have also given that
there are 150 names that appear on both lists,
So,
Number of unique names in the first list is given by
![1200-150=1050](https://tex.z-dn.net/?f=1200-150%3D1050)
Number of unique names in the second list is given by
![900-150=750](https://tex.z-dn.net/?f=900-150%3D750)
Therefore, total number of unique names is given by
![1050+750=1800](https://tex.z-dn.net/?f=1050%2B750%3D1800)
Hence, there are 1800 unique names from both the lists.
Answer:
363
Step-by-step explanation:
Formula for area of a circle
A = πr^2
Where r = radius
The circle has a given radius of 11
To find the area of the circle we simply substitute r in the formula with the value of the radius (11)
( Also note that the question says to use 3 for π )
A = πr^2
π = 3
r = 11
Substitute values in formula
A = (3)(11)^2
11^2 = 121
A = 121(3)
121(3) = 363
A = 363

To Write percentage in decimal or fraction we divide it by 100
therefore,
![\begin{gathered}\\\implies\quad \sf 2\% = \frac{2}{100} \\\end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%5C%5C%5Cimplies%5Cquad%20%5Csf%202%5C%25%20%3D%20%5Cfrac%7B2%7D%7B100%7D%20%5C%5C%5Cend%7Bgathered%7D%20)
![\begin{gathered}\\\implies\quad \sf 2\% = 0.02 \\\end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%5C%5C%5Cimplies%5Cquad%20%5Csf%202%5C%25%20%3D%200.02%20%5C%5C%5Cend%7Bgathered%7D%20)
Half of 0.02 = ![\sf\frac{1}{\cancel2} \times\cancel{0.02}](https://tex.z-dn.net/?f=%5Csf%5Cfrac%7B1%7D%7B%5Ccancel2%7D%20%5Ctimes%5Ccancel%7B0.02%7D)
![\implies\boxed {0.01}](https://tex.z-dn.net/?f=%5Cimplies%5Cboxed%20%7B0.01%7D)
I believe that is 275 because percent is just out of one hundred
Step-by-step explanation:
I am not fully sure what your teacher is aiming for. it friends very much on what you were just discussing in class (which I don't know).
but the first thing coming to mind is a minus sign ("-"). squaring a negative number removed the minus and makes the result equal to squaring the same positive number.
just for the undoing the 1/2 :
that is, because a fraction as exponent specifies in its denominator the root to be calculated for the basic value or expression.
so, 1/2 means square root. and yes, square is the inverse function of a square root, and it "undoes" the square root.
in exponent calculation it just means that for exponent 1 to the power of exponent 2 we simply multiply both exponents. and so, 1/2 × 2 = 1
FYI - the numerator still represents an original "to the power of" operation.
so, e.g. 3/2 would mean put the basis to the power of 3 and then do the square root of that result. or the other way around. these operations are commutative (the sequence does not matter).
