Answer:
10,600
Step-by-step explanation:
The bacteria grew in 2 hours by 800. Divide that and that it by 400 per hour.
Since it is a proportional rate, we can assume that the rate continue through till midnight.
Since midnight is 12 hours after noon then the bacteria grow 400 (12)=4800.
We add this to the population at noon 5800+4800=10,600.
<2 = 90
If the lines are perpendicular, the angles are 90 degrees
X= -3/2
6x/6=-9/6
-1 to the nearest whole number.
(-0.3) ÷ (-0.2)+(-2.56)
Order of operations - the division is done first:
= 1.5 = (-2.56)
= 1.5 - 2.56
= -1.06.
