b. 65 days into hours

Q: b. 65 days into hours

The correct answer is: $1560\text{ hours}$ Explanation We convert days to hours using the fixed conversion factor that 1 day = 24 hours. Multiply the number of days by 24 to get hours. Steps: Conversion factor: $1\text{ day} = 24\text{ hours}$ Multiply: $$65\text{ days} \times 24\text{ hours/day} = 1560\text{ hours}$$ Therefore, 65 days equals $1560\text{ hours}$.

Q: How many feet in one third of a mile?

The correct answer is: $1760\text{ ft}$ Explanation We convert one third of a mile to feet using the standard conversion factor $1\text{ mile} = 5280\text{ ft}$. Multiply that by $\tfrac{1}{3}$ to find one third of a mile. Steps: Conversion factor: $$1\text{ mile} = 5280\text{ ft}$$ Multiply by one third: $$\tfrac{1}{3}\times 5280\text{ ft}$$ Evaluate the product: $$\tfrac{5280}{3}\text{ ft} = 1760\text{ ft}$$ Therefore, one third of a mile equals $1760\text{ feet}$. Quick check: since $1\text{ mile}=1760\text{ yards}$ and $1\text{ yard}=3\text{ ft}$, $1\text{ mile}=1760\times3=5280\text{ ft}$, and dividing $5280$ by $3$ again gives $1760\text{ ft}$ (consistent).

Q: How long is 20 cm. in inches?

The correct answer is: $7.874\text{ in}$ (approximately $7.87\text{ in}$) Explanation We use the exact conversion $1\text{ in} = 2.54\text{ cm}$ to convert centimeters to inches. Steps: Conversion factor: $1\text{ in} = 2.54\text{ cm}$ Set up the conversion: $$20\text{ cm}\times\frac{1\text{ in}}{2.54\text{ cm}}=\frac{20}{2.54}\text{ in}$$ Calculate: $$\frac{20}{2.54}\approx7.874015748\text{ in}\approx7.87\text{ in}$$ Therefore, 20 cm is about $7.87\text{ in}$ (roughly $7\frac{7}{8}\text{ in}$).

Q: How do you convert 120lbs to kilograms?

The correct answer is: $54.4310844\text{ kg}$ (approximately $54.43\text{ kg}$). Explanation Convert pounds to kilograms using the exact conversion factor $1\text{ lb} = 0.45359237\text{ kg}$. Multiply 120 pounds by that factor to get kilograms. Steps: First step: $$1\text{ lb} = 0.45359237\text{ kg}$$ Second step: $$120\text{ lb} \times 0.45359237\frac{\text{kg}}{\text{lb}} = 54.4310844\text{ kg}$$ Final step: Round as needed. Rounded to two decimal places: $$54.43\text{ kg}$$ (to one decimal place: $54.4\text{ kg}$). Therefore, $120\text{ lb} \approx 54.43\text{ kg}$.

Q: How many kg is 145 pounds?

The correct answer is: $65.77089365\text{ kg}$ Explanation We use the exact conversion factor $1\text{ lb} = 0.45359237\text{ kg}$. Steps: Conversion factor: $$1\text{ lb} = 0.45359237\text{ kg}$$ Multiply: $$145\text{ lb} \times 0.45359237\frac{\text{kg}}{\text{lb}} = 65.77089365\text{ kg}$$ Rounded (typical): $$\approx 65.77\text{ kg (to 2 decimal places)}$$ Therefore, 145 pounds is about $65.77\text{ kg}$ (≈ $65.7709\text{ kg}$ if more precision is needed).

Q: How many fluid ounces are in 500 ml?

The correct answer is: $16.907\text{ US fl oz (approximately)}$ (also $17.598\text{ Imperial fl oz (approximately)}$). Explanation Most people use US fluid ounces unless otherwise specified. I’ll show both common conversions. Steps: Conversion factor (US): $$1\ \text{US fl oz}=29.5735295625\ \text{mL}$$ Compute (US): $$500\ \text{mL}\times\frac{1\ \text{US fl oz}}{29.5735295625\ \text{mL}}=\frac{500}{29.5735295625}\ \text{US fl oz}=16.90701135\ \text{US fl oz}$$ Round: $$\approx16.91\ \text{US fl oz}$$ Quick note (Imperial): $$1\ \text{Imp fl oz}=28.4130625\ \text{mL}$$ $$500\ \text{mL}=\frac{500}{28.4130625}\ \text{Imp fl oz}\approx17.598\ \text{Imp fl oz}$$ Therefore, 500 mL ≈ $16.91\ \text{US fl oz}$ (≈ $17.60\ \text{Imperial fl oz}$).
