Answer:
Step-by-step explanation:
The question relates to dividing a fraction by proper and another fraction
The given expression is presented as follows;
We rearrange the fractions as improper fractions for easier division as follows;
Therefore, we have;
The answer is
the option A
<span>The graph shows the solution of the system of inequalities
y> -3
y<=-x
using a graph tool
see the attached figure</span>
We have
so this is indeed a difference of squares. Factorizing would give
making the answer D.
We can further factor the first term here and write
but that's clearly out of the scope of this question.
Answer:
75.391
Step-by-step explanation:
193x100/256=75.391
You want to know how long it'll take for the bacteria to grow
to (800/500) = 1.6 times their initial population.
The number of double-times it'll take is
[ log(1.6) / (log(2) ] = 0.6781 .
The double-time for these particular critters is 12 hours,
so it'll take them
0.6781 x 12 hours = 8.137 hours
= 8 hours 8.2 minutes .
