Answer:
A student with GPA of 2.15 worked 47.8 hours per week.
Step-by-step explanation:
To find the numbers of hours worked when the GPA is 2.15, we solve the equation when or:
which can be rewritten as (<em>by subtracting 2.15 from both sides)</em>
<em /><em>.</em>
We solve this using the quadratic equation which says, for ,
in our case
,
therefore, we have
and since only the positive solution applies to the real word, we choose , and therefore, a student with GPA of 2.15 worked 47.8 hours per week.
I = p r t
I = 315(.015)(3) = 14.18
Add interest to the principle.
$315. + 14.18 = $329.18
<span>numbers of seats in a row makes an arithmetic series
chairs in the nth row
an = 4 + 23*5 = 119
and the sum is
sn = (4 + 119) * 24/2 = 1476</span>
Answer:
k=6
Step-by-step explanation:
3k-7=11
add -7 on both sides
11+7=18
3k=18
divide both sides on both sides
k=6
