1. what is the temperature of 25°c equal to in fahrenheit?

a. 77°f
b. 85°f
c. 98.6°f
d. 102.6°f

Explanation:

22.

Step1: Unit conversion factor

We know that \(1\space kg = 2.2\space lbs\)

Step2: Calculate the weight in pounds

If the tumor weighs \(m = 2\space kg\), then using the conversion formula \(m_{lbs}=m_{kg}\times2.2\), we substitute \(m_{kg} = 2\)

\(m_{lbs}=2\times2.2=4.4\space lbs\)

Answer:

C. \(4.4\space lbs\)

23.

Step1: Unit conversion factor

We know that \(1\space g= 1000\space mg\), or \(\frac{1\space g}{1000\space mg}=1\)

Step2: Calculate the mass in grams

If \(m = 3000\space mg\), then \(m_{g}=3000\space mg\times\frac{1\space g}{1000\space mg}\)

\(m_{g}=\frac{3000}{1000}=3\space g\)
