Answer:
A) 
B)
Step-by-step explanation:
To answer this question first we define what are rational numbers.
A rational number is a number that can be expressed in the form of a fraction
, where x and y are integers and y ≠ 0.
a) 0.12345
This can be written in fraction form as

Now, we simplify this fraction to lowest form. Simplified form of the above fraction is
. This simplified form was obtained by dividing both numerator an denominator by 5.
b) This number can be written in fraction form as 
Now, we simplify this fraction.
The simplified form of the above fraction is
as the numerator and denominator have no common factor.
Answer:
9x9x3.66=296.4
Step-by-step explanation:
length x width x height
this is how i solved it:
Sin30+cos300=1/2+1/2=1
Cos30+sin300=rad3/2-rad3/2=0
Sin(30+300)=sin330=<u>-1/2</u>
hope this helps:)
The distance from the edge of the fountain to the centre is approximately 23.87 inches.
The water fountain forms a circle. The distance around the water fountain is the circumference of the circle formed.
Therefore,
circumference = 2πr
150 = 2πr
The distance from the edge of the fountain to the centre is the radius of the circle formed. Therefore,
75 = πr
r = 75 / 3.14159
r = 23.8732616287
r = 23.87 inches
The distance from the edge of the fountain to the centre is approximately 23.87 inches.

Answer:the derivative of 1/x =-1/x^2
Step-by-step explanation:
1/x can also be written as x^-1
Therefore d/dx of x^-1
=-1*x^-1-1
=-1x^-2
Which can also be written as -1/x^2
Note: d/dx also means derivative of x
And d/dx (a/x^b) =(a*-b) /x^(b+1)
Where a and b represents a variable
