285 × .30 = 85.50
285 - 85.50 = 199.50
Answer:
Step-by-step explanation:
a)
the sum of all angles in a quadrilateral must be 360º
y+88+25+35 = 360
y = 360=88-25-35
y = 212º
b)
the sum of all angles in an octagon must be 1080º
45+45+140+140+6y = 1080
6y = 1080-90-280
6y = 710
y = 710/6
y=~ 118,3º
Answer: B. 4,000
Step-by-step explanation:
Given: The initial amount of bacteria in the dish A= 500
Since, The amount of bacteria in the dish doubles every 3 hours.
The multiplicative rate of change after every 3 hours = 2
Time period = 3 hours
By exponential function, we have the amount of bacteria after time period 'x' is given by :-
, where A is the initial amount , b is the multiplicative rate of change in time period x.
Number of 3 hours period in 9 hours = 3
Therefore, x=3
Therefore, the amount of bacteria in the dish after 9 hours is given by :_
