Answer:
D. 18.9 ÷ 9
Step-by-step explanation:
we need to divide
1.89 ÷ 0.9 but write it in different form
so ,we need to eliminate decimal from 0.9
as 0.9*10 = 9
thus,we multiply both 1.89 and 0.9 with 10, then we will have
(1.89*10) ÷ (0.9*10)
=> 18.9 ÷ 9
Thus, based on above calculation new look would be D. 18.9 ÷ 9

Answer:
D. 80
Step-by-step explanation:
We have the following function :
(I)
Where 
is the monthly fee for after - school care and preschool.
Where 
represents the number of hours spent in after - school care.
We know that the total monthly bill for one child was $750 ⇒
Using (I) we will find the value of the hours '''' that verifies the expression ⇒
⇒

Answer:
-13
Step-by-step explanation:
3x^3 - 2y^-6x^2y^2+xy
x=2/3 and y=1/2
Solve :
3x^3 - 2y^-6x^2y^2+xy
Put value of x and y in this equation
= 3(2/3)^3 - 2(1/2)^-6(2/3)^2(1/2)^2+(2/3)(1/2)
= -13
