Answer:
A = 100 
Step-by-step explanation:
You have to use the area of a trapezoid formula:
A =
(a + b)
Now, substitute the values of the height and the bases:
A =
(10 + 15)
Finally, simplify the equation to solve for the area:
A = 4(25)
A = 100 
Answer:
1/6 hours
Step-by-step explanation:
Since it wants a fraction form all you have to do is subract 1/3 from 1/2
1/2 - 1/3
cross multiply:
3/2-2/3
subtract the numerator but multiply the denominator and simplify if you have to:
1/6
That would be week 2 and 4 (B). They are both at 12 students attending
