1648
Step-by-step explanation:
72 is the volume because u multiply 12 times two then multiply by 6
Answer:
a=16
Step-by-step explanation:
The distributive property states that

Therefore using the distributive property

=
Expanding the brackets
.....(i)
Comparing with the form
-----(ii)
The coefficient of y in (i) is 16 which corresponds to a and the likewise the coefficient of xy
Therefore, a=16
Important variables to know:
I = interest
P = principal (investment)
R = simple interest rate
T = years
Formula: I = PRT
What information do we have?
I = $960
P = $4000
T = 3 years
R = ?
Plug into formula:
960 = 4000(3)(R)
960 = 12000R
R = 960/12000
R = .08
A. $4000 + $960 = $4960. (A= P+ I)
B. 8% (.08)
Part 2: 1080 = 4000*.09*3
A = 5080 - 4960 =$420.
