Answer:
lower bound: 315 litres
upper bound: 324 litres
Step-by-step explanation:
The following rules apply:
- if the last digit of the number is 1, 2, 3, or 4; it is rounded down
- if the last digit of the number is 5, 6, 7, 8, or 9.
; it is rounded up
So:
314 is  rounded to 310
315 is  rounded to 320
324 is  rounded to 320
325 is  rounded to 330
 
        
             
        
        
        
It would take about 57 hours for the number of spores to be less than 500 spores.
<h3>
Exponential Function</h3>
An exponential function is in the form:
y = abˣ
Where y,x are variables, a is the initial value of y and b is the multiplication factor. 
Let y is the number of pores after x hours. 
a = 6200, b = 100% - 20% = 0.8, hence to be less than 500 spores:

(x/5) * ln(0.8) < ln(0.08)
x > 56.4 hours
It would take about 57 hours for the number of spores to be less than 500 spores.

Answer:
^G=98°
Step-by-step explanation:
So you know that angle x and angle g summed up together make 180°.
^F+^H+^G= 180°
<=> 53°+45°+^G=180°
<=> ^G= 180°-98°=82°
180°-82°=98°
