Answer: The answer is (A) [0,100].
Step-by-step explanation: Given in the question that a marine biologist Kelsey determined that the population of Blue Whales off the coast of Antarctica varies with time as shown in the given graph.
The population of Blue Whales (y) is plotted on the Y-axis and the time in months (x) is plotted on the X-axis.
We need to find the range of the population of Blue Whales off the coast of Antarctica from 0 to 10 months.
We can see from the attached graph that
when x = 0, then y = 0,
when x = 10, then y = 100.
That is, when time varies between 0 to 10 months, then the population of Blue Whales varies between 0 and 100.
Thus, the correct option is (A) [0,100].
Answer:
1km is 1000m
so 100ratio 1000m
1 ratio 10
please nark brainliest i really ned it it plzzz please
9000 x .08 = 720
720 x 5= 3600
9000-3600= 5400
5,400

Answer:
a). Nadia made a total of $825 last week in commission sales
b). The total amount Nadia in commission in 2011=$42,900
Step-by-step explanation:
Step 1
Express the amount in commission she earns from her sales as follows;
C=S×r
where;
C=commission earned
S=total value of stock sales
r=commission rate
In our case;
C=unknown
S=$7,500
r=11%=11/100=0.11
replacing;
C=11% of 7,500
C=(11/100)×7,500
C=0.11×7,500=825
Nadia made a total of $825 last week in commission sales
b). To express the total amount she made in 2011, we derive the formula below;
Total amount (2011)=Average weekly commission×number of weeks in 2011
where;
Average weekly commission=$825
number of weeks in 2011=52
replacing;
Total amount (2011)=(825×52)=42,900
The total amount Nadia in commission in 2011=$42,900
