When Kaira wrote 96 +12 as 12(8+1), she "factorized" 12, that is Karira found that 12 is a factor of both 96 and 12.
then she wrote 95+15=5(19+3), that is she factorized 5,
5 is a factor of both 95 and 15 because 95=5* 19 and 15=5*3
To use this method to calculate 38+11 we need 38 and 11 to have some common factor (different from 1),
but 11 is a prime number, that is, it has no factors except 1 and 11. We can only apply the method if 11 is a factor of 38, but it is not.
Answer: The method is called "factorization", and it cannot be applied to calculate 38+11
We have that
surface area of the cylinder=2*[pi*r²]+[2*pi*r*h]
r=(4x+3)
h=3*r=3*(4x+3)
S=2*[pi*(4x+3)²]+[2*pi*(4x+3)*(3*(4x+3))]------> 2*[pi*(4x+3)²]+[6*pi*(4x+3)²]
S=8*pi*(4x+3)²----> 8*pi*[16x²+24x+9]-----> 402.12 x²+603.19x+226.19
the answer is S=402.12 x²+603.19x+226.19 (8pi[16x²+24x+9])

Answer:
Yes, Sasha is correct. The mean amount she makes is $58.33 in a day.
Step-by-step explanation:
Given that Sasha’s daily tips this work week were $43, $32, $65, $88, $50, and $72
Let us arrange in ascending order
32, 43,50,65,72,88
There are 6 entries hence 3rd and 4th are middle entries
Median = (50+65)/2=115/2=57.5
Sum of all entries = 350
No of entries =6
Mean amount = average = sum/6
=350/6
=58.33
Hence mean = 58.33
Out of 4 options we get I option only right
Yes, Sasha is correct. The mean amount she makes is $58.33 in a day.
