Answer:a) 870
b) 435
Step-by-step explanation:
a)
number of photos to be posted =n = 30
number of web pages on which they would be posted is 2
Since the order in which the photos appear on the web pages matters,
Number of ways = 30 permutation 2
=870 ways
b)
Since the order in which the photos appear on the web pages does not matter,
Number of ways = 30 combination 2
= 435 ways
72 ÷ o should be the algebraic expression.
2 1/2
65/26
26*2=52
65-52=13
13/26 = 1/2
The slope is 1
The slope always is the coefficient of the variable, x, when an equation is in slope intercept form
500+600+900+400+600= 3000
