Answer:
-6m^2 *n^2
Step-by-step explanation:
formula: (m^x)/(m^y)= m^(x-y)
apply formula for (4m^2)/(2m^-3)
=(4m^(2--3)/(2)
=4m^5/2
divide 4/2
=2m^5
next part 3n^5/(-mn)^3
3n^5/(-mn)^3
expand
=3n^5/ (-m^3*n^3)
=3n^(5-3)/ -m^3
=3n^2/ -m^3
both parts:
(2m^5* 3n^2)/ -m^3
= -(2m^5* 3n^2)/ m^3
= -(2m^(5-3)* 3n^2)/ 1
= -(2m^2* 3n^2)
= -(6m^2*n^2)
= -6m^2 *n^2

Answer:
without the sales, he would have spent $44.57
Step-by-step explanation:
Let the amount he would have spent without the sales be x. Now, if there is a 65% discount, what this means is that he is exactly paying for 100 - 65% = 35%
Now, it is this 35% of X that is equal to the amount he paid
Thus, mathematically, we have the following;
35/100 * x = 15.60
35x = 15.6 * 100
35x = 1560
x = 1560/35
x = $44.57
This means that without the sales discount, he would have paid $44.57
Answer:
Amelia
Step-by-step explanation:
lily made 85% of her shots
Amelia made 31 out of 36 of her shots
31/36 = 0.86
Amelia made 86% out of her shots
86% > 85%
