180 of 72% is 129.6. 180*72= 12960. Since 72% = .72, you need to put the decimal 2 places behind the decimal.
10(z-3) = 3*8
10z-30 = 24
add 30 to both sides
10z = 54
divide both sides by 10
z = 5.4
but, if you meant z- 3/8, then
z = 27/40
13.5% of $1500 = $202.50
12 months = 202.50
1 month = $16.875
4 months = 67.50
Total amount = $1500 + $67.50
Total amount = $1567.50 (Answer B)
(P1*V1)=(P2*V2)
P1= 5 atm
P2= 3 atm
V1= 4L
V2=?
(5*4)=(3*V2)
20=3(V2)
V2=20/3 L which is 6.66666667L
1 pound = 0.453592 Kilograms
Mass of the rice in pounds = 3.18 pounds
3.18 pounds = (3.18*0.453592) Kilograms
= 1.442424 Kilograms
The mass of the rice in kilograms is 1.442424 Kilograms.
