Question

question 19
5 ounces = ______ g

question 20
59 deg f = ______ deg c

question 21
210 deg f = ______ deg c

Explanation:

Question 19:

Step1: Recall ounce to gram conversion

1 ounce (oz) is approximately equal to 28.35 grams (g). So, to convert ounces to grams, we use the formula: \( \text{Grams} = \text{Ounces} \times 28.35 \)

Step2: Substitute the value

We have 5 ounces. So, \( 5 \times 28.35 = 141.75 \)

Step1: Recall Fahrenheit to Celsius formula

The formula to convert Fahrenheit (°F) to Celsius (°C) is \( C=\frac{5}{9}(F - 32) \)

Step2: Substitute \( F = 59 \)

Substitute \( F = 59 \) into the formula: \( C=\frac{5}{9}(59 - 32)=\frac{5}{9}(27) \)

Step3: Calculate the result

\( \frac{5\times27}{9}=5\times3 = 15 \)

Step1: Recall Fahrenheit to Celsius formula

The formula to convert Fahrenheit (°F) to Celsius (°C) is \( C=\frac{5}{9}(F - 32) \)

Step2: Substitute \( F = 210 \)

Substitute \( F = 210 \) into the formula: \( C=\frac{5}{9}(210 - 32)=\frac{5}{9}(178) \)

Step3: Calculate the result

\( \frac{5\times178}{9}=\frac{890}{9}\approx98.89 \) (rounded to two decimal places)

Answer:

141.75
