Answer:
Step-by-step explanation:
Firstly, we should begin to know what leveling off is.
Leveling off- to stay the same after a period of increase
Nearing the end of the graph you can see there is no continuous increase for the rotifers. That can be explained by carrying capacity. The flask has limited space.
Answer:
3 students with red hair
12 students with brown hair
Step-by-step explanation:
1/6 times 18 = 18/6 = 3 students with red hair
4/6 times 18 = (18 times 4)/6= 12 students with brown hair
There are 60 minutes in one hour
to find 1/6 of an hour, divide 60 by 6:
60/6=10
Jaxson played for 19 minutes
to find 1/3 of an hour, divide 60 by 3:
60/3=20
Hailey played for 20 minutes
20>10
Hailey played video games for 10 minutes longer than Jaxson
Answer:
a) $1520
b)
$209195
Step-by-step explanation:
The range of salaries forms an arithmetic sequence with the first term as 25325 and its 7th term as 34445:
a) The raise the person can get each year is the common difference of the progression, d.
The nth term of an arithmetic progression is given generally as:

where a = first term = 25325
d = common difference
Therefore, the 7th term (34445) will be:
34445 = 25325 + (7 - 1)d
34445 = 25325 + 6d
=> 6d = 34445 - 25325 = 9120
d = 9120 / 6 = $1520
Therefore, the raise the person gets each year (common difference) is $1520.
b) The total amount the person will earn after 7 years is the sum of the salaries of all 7 yeas.
The sum of an arithmetic progression up to the nth term is given as:

Therefore, the sum of the person's salary for the 7 years is:

$209195
That is the total amount of salary after 7 years
