Printer A prints for 10 minutes, so prints
... (30 pages/minute)×(10 minutes) = 300 pages
Printer B prints for 7 minutes, so prints
... (40 pages/minute)×(7 minutes) = 280 pages
At the end of 10 minutes, the two printers will have printed
... 300 pages + 280 pages = 580 pages
Answer:
Step-by-step explanation:
1. P = (width + lengh) * 2 = (23 + 10) * 2 = 33 * 2 = 66
A = width * lengh = 23 * 10 = 230
2. width = 7
P = (width + lengh) * 2 = ( 7 + 9) * 2 = 16 * 2 = 32

Solution
Find the mid point of A and B.
The mid point of A and B is (-1. 0.5)
Now find mid point of (0, 4) and (-1, 0.5)
= [(0 + (-1)/2 , (4 +0.5)/2 ]
= (-1/2, 4.5/2)
= (-0.5, 2.25)
The answer is (-0.5, 2.25)
Thank you.
