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
8*.8=6.4
4x+6.4=40
40-6.4=33.6
33.6/4=x
8.4=x
Hope this helps :)
Answer:
B. 2 (Second Option)
Step-by-step explanation:
Four times: ⇒ 4
Number:⇒ y
4y+3=11
<em>Subtract by 3 both sides of equation.</em>
<em>4y+3-3=11-3</em>
<em>Simplify.</em>
<em>11-3=8</em>
<em>4y=8</em>
<em>Divide by 4 both sides of equation.</em>
<em>4y/4=8/4</em>
<em>SImplify, to find the answer.</em>
<em>8/4=2</em>
<em>y=2 is the correct answer.</em>
<em>2 is the correct answer.</em>
