6!=720
6*5*4*3*2*1=720
Because you have 6 possible choices for first seat, 5 possible choices for the second seat, etc, etc
(16x^1/6y^-2)^3/2 / (x^-1/6y^6)^3/2
=(4^2)^3/2 (x^1/6)^3/2 (y^-2)^3/2 / (x^-1/6)^3/2(y^6)^3/2
= 4^3 x^1/4 y^-3 / x^-1/4 y ^9
= 64 x^(1/4 +1/4) y^(-3-9)
= 64 x^1/2 y^-12
= 64 x^1/2 / y^12
answer is D.64 x^1/2 / y^12
Answer:
35% of the sixth grade is in the chess club
Step-by-step explanation:
if there are 100 students consider that as 100%
20 is a fifth of 100
20 x 5 =100
since 7/20 is a fraction you multiple the numerator (7) with the same number you multiplied to the denominator (20) which is 5.
7 x 5 = 35
35/100 = 35%
So it's saying to
(5x^2 + 10x - 5) - (7x^2 + 4x - 9)
Collect the like terms
and regroup
(5x^2 - 7x^2) + (10x - 4x) + ( -5 + 9)
Simplify
-2x^2 + 6x + 4
Hope this helps :)
