Subtracting 3.25 hours from 10 PM is subtracting 3 hours and 15 minutes from 10 PM. Doing this, we get that the game started at 6:45 P.M. Hope this helped!
Answer:
The integer is -20
Step-by-step explanation:
Is means equals and more than means add
W = 15+-35
W = -20
The population of the bacteria after 7 hours is 230 bacteria.
An exponential function is given by:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the population of bacteria after x hours.
Given that he starts his experiment with 200 bacteria, hence
a = 200
The bacteria grow at a rate of 2% per hour, hence:
b = 100% + 2% = 1.02
The exponential equation becomes:
y = 200(1.02)ˣ
After 7 hours:
y = 200(1.02)⁷ = 230
The population of the bacteria after 7 hours is 230 bacteria.

4x+10=90
4x=80
x=20
Why 90°? This is because the angle subtended in a semi-circle to the circumference is 90°.
