Answer:
8!=40320
Step-by-step explanation:
SInce their are 8 athletes and 8 positions we can assume this: The first sprinter has 8 positions to end in, the next has 7 places to finish in, the third has 6 places and so on... Using this we can multiply these possibilities to find that the possibilities are 8×7×6×5×4×3×2 which results in 40320 (this function is known as a factorial and denoted !).
Answer: B. 1/2(y - 116) = 64
Step-by-step explanation:
Since, we know that,
The angle formed by two tangent = 
= 
Here, Major arc = y°
Minor arc = 116°
And, Angle made by two tangents YX and YZ,
( because, 
)
⇒ 
Which is the required equation to find y, the measure of XWZ.
Thus, Option B is correct.
<h3>Calculate percentage of a number</h3>
For this, multiply 150 × .20 = 30
Therefore, 20% of 150 is 30.
- So, the correct option is "D".

This is the concept of algebra. Let the price of envelope be $x ;
the price of notepad is $ 8x
the price of postcard is $ (x-0.02)
the total amount is $1.68
thus:
x+8x+(x-0.2)=1.68
10x-0.02=1.68
10x=1.68+0.02
10x=1.7
thus
x=0.17
hence the price of an envelope is x=$0.17= 17 cents
the price of notepad is 8x=0.17*8=$1.36
the price of a postcard is x-0.02=0.17-0.02=$0.15= 15 cents
