Answer:
30 tiles
Step-by-step explanation:
SO we need to find the area of the wall so we do
8 feet * 5 feet = 40 feet squared
then we find that area in inches
40*12=480
Now we find the area of the tiles
4*4=16
So now we divide to find how many tiles are needed
480/16=30
Our answer is 30
The probabilities of all possible outcomes in a distribution must sum to 1.

Answer:
b=204
Step-by-step explanation:
The law of sine states that: 
We know that a triangle has 180° total, so we can subtract the two angle measures we know to find the third angle:
°.
Using these two things, we can come up with the equality
, which we can use to solve for side b.
, so we know that
.
Next, we would multiply both sides by b to get
.
Sin49°≈0.75471, so to find b we would multiply 0.75471×270=203.77
Since the problem asks us to round to the nearest whole number, b=204
Hope this helps! :)
