Step-by-step explanation:
1) For each chart we will fill in 4 rows, as it says, to show 0.4 or 4/10
2) For this part, we will shade in 4 rows twice, or 8, as it says. This shows 0.4 being multiplied by 2.
b) 8/10 or 0.8 because we have shaded 8 out of the 10 rows, 8/10 = 0.8
c) 0.8 is our answer as we have found out from the above steps
Have a nice day!

Answer:
7.2
Step-by-step explanation:
36 divided by 5 = 7.2
7.2 times 5 = 36.
R = = 3.6 and A = 2
given that R is inversely proportional to A, then
R = ← k is the constant of variation
To find k use the condition R = 12 when A = 1.5
k = RA = 12 × 1.5 = 18
the equation is therefore
R =
when A = 5, then
R = = 3.6
when R = 9, then
9 = ( multiply both sides by A )
9A = 18 ( divide both sides by 9 )
A = 2
