Answer:
3 question papers
Step-by-step explanation:
If the teacher takes 15 minutes to mark 1 question paper. Then they will probably take 30 minutes to grade 2 question paper. Because 15 minutes+15 minutes=30 minutes. Then if you and another 15 minutes which will be 40 minutes because 15 minutes+15 minutes+15 minutes=40 minutes.
Hence, the teacher will mark 3 question papers in 40 minutes
Answer:
please it would be helpful if u pay attention in class
Step-by-step explanation:
if ur always asking other for help you'll never know how to do it on ur own
X + y = 13
x - y = 5
x = (13 - y)
(13-y) - y = 5
13 - 2y = 5
-2y = -8
y = 4
x - 4 = 5
x = 9
x=9, y = 4
For this case we can model the problem as a cylinder.
The volume of a cylinder is given by:

Where,
Ab: base area
h: cylinder height
Substituting values in the equation we have:

From here, we can clear the area of the base
Answer:
An equation that can be used to find the area of the circular base is:
Answer: $67.20
Step-by-step explanation:
56 × 0.2 = 11.2
11.2 + 56 = $67.20
