Answer 1

`\text{5. } 22\text{ gallons},\\\text{6. }8.5344\:\text{m or }8.5\text{ m rounded to the nearest tenth},\\\text{7. }49^(\circ)\mathrm{C}`

Explanation:

Question 5:

Use the conversion
`1\:\mathrm{liter}=0.264172\:\mathrm{gallon}` to convert from liters to gallons:

`85\cdot 0.264172\approx \boxed{22\:\text{gallons}}`

Question 6:

Use the conversion
`1\text{ foot}=0.3048\text{ meters}` to convert from feet to meters:

`28\cdot 0.3048=\boxed{8.5344\:\mathrm{m}}`

Question 7:

Use the conversion
`x^(\circ)\text{F}\implies (5)/(9)(x-32)^(\circ)\text{C}` to get:

`120^(\circ)\text{F}=(5)/(9)(120-32)^(\circ)\text{C}=(5)/(9)(88)^(\circ)\text{C}\approx \boxed{49^(\circ)\text{C}}`
