Answer:
47
Step-by-step explanation:
the formula is πr²h/3= pi=22/7, so 22/7x 3x 5/3= 47.12389 simplified= 47
Answer:
The inverse of
is 
Step-by-step explanation:
Given equation :

Replace x with y and y with x
So, 
So, Option C is correct
Hence The inverse of
is 
Answer:
x = 35 , y = 72.5
Step-by-step explanation:
(a)
x and 35° are vertical angles and are congruent, then
x = 35
(b)
y. y and 35 lie on a straight line and sum to 180°, that is
y + y + 35 = 180
2y + 35 = 180 ( subtract 35 from both sides )
2y = 145 ( divide both sides by 2 )
y = 72.5
The answer is -5 all you have to do is divide -15 by 3
The time it would take for the bacteria to reach 1119 is 5.83 hours
<h3>Calculations and Parameters:</h3>
Given the function:

- Initial amount= 50
- amount after 3 hours= 80
To find the exponential growth;
80 = 

If there is a constant growth, then to get to 1119:
1119= 
3.8 = 0.533*t
t= 5.83 hours
Therefore, it would take 5.83 hours for the bacteria to increase to 1119.
