Answer:
180 pages
Step-by-step explanation:
Since her photocopy session is 25 pages per minute, the total number of pages photocopied in 4 hour session can be calculated as;
number of pages = time × speed
= (4 × 60) × 25
= 240 ×25
= 6000 pages
Thus, number of pages photocopied in 4 hours is 6000.
For every 100 pages, 3 would contain some type of printing error. The number of pages she expect with printing error during 4 hour session can be determined as;
= 
× 3
= 60 × 3
= 180 pages
The expected number of pages with printing error during 4 hour photocopying session is 180 pages.
Answer:
28
Step-by-step explanation:
Use the pythagorean theorem and solve for a:
a² + b² = c²
a² + 21² = 35²
a² + 441 = 1225
a² = 784
a = 28
So, the missing length is 28.

Answer:
= 
Step-by-step explanation:
Differentiate xy using the product rule, then
Given
x - y = xy
1 - = x. + y. 1 = x + y ( subtract 1 from both sides )
- = x + y - 1 ( subtract x from both sides )
- - x = y - 1 ( multiply through by - 1 )
+ x = 1 - y
(1 + x) = 1 - y ← divide both sides by (1 + x)
=
