New perimeter will be equal = old perimeter*3=36*3=108
Answer:
C. 
Step-by-step explanation:
We have been given a triangle. We are asked to find the measure of angle Z using Law of cosines.
Law of cosines: 
, where, a, b and c are sides opposite to angles A, B and C respectively.
Upon substituting our given values in law of cosines, we will get:
Now, we will use inverse cosine or arc-cos to solve for angle Z as:
Therefore, the measure of angle Z is approximately 51 degrees.
Answer:
<h2>$373.21</h2>
Step-by-step explanation:
Step one:
weekly pay = $185
commission= 5.5% of sales= 0.055
let the sale be x
and his gross pay be represented by y
hence the expression for the total/gross pay is
y=0.055x+185
Step two:
Required is the gross pay y for x=3422
substituting we have
y=0.055*3422+185
y=188.21+185
y=373.21
Hence for a sale of $3,422 made his gross pay is $373.21
Answer:
2/3
Step-by-step explanation:
I think it is 2/3 because 20 is the probability and 30 are the users. So basically, it is the probability over the total in this case 30. 20/30=2/3. Hope it helps?
Time spent is independent and the amount earned is dependent should be number 1
