Well for the first one the ratio would be 12:6 I believe
Answer:
1,877
Step-by-step explanation:
845/13 = 65
65 x 32 = 2,080
2,080 - 203 = 1,877
Answer:
100cubic inches
Step-by-step explanation:
varies inversely
pv = k
Find the constant of variation:
volume of 180 cubic inches under a pressure of 5 pounds
5 * 180 = k
k = 900
volume if the pressure is increased to 9 pounds per square inch?
9v = 900
divide both sides by 9
v = 100
If it costs 650 per kg then 500g will cost half of that as 500g is half of a kg so the answer is 650/2 = 325
