20 A strip of wood 78 inches long can be cut into 20 3 3/4 inch pieces. (78/3.75 = 20.8 Since you can't have a .8 piece of wood, the answer is 20)
Answer:
-2343 is a negative integer
5 and 6 (5 being the square root of 25 and 6 being the square root of 36, which are the closest perfect squares)
The answer is A
start by isolating the y variable
the rest of the work is shown here
T = 5 a
i = 4% aa
j = 1200
c = ...
j = cit/100
c = 100j / it
c = 100*1200 / 4*5
c = 120000 / 20
c = 12000/2
c = 6000
montante
M = c+j
M = 6000+1200
M = 7200
