b) The recipe calls for 125 g of diced onions. How many 4 oz onions should he dice?

Answer 1

Answer:

For a: Yes, he has gained weight.

For b: The number of onions required is 1.

Explanation:

• For a:

We are given:

Weight of Brandon checked earlier = 183 lb

Converting this into kilograms, we use the conversion factor:

1 kg = 2.205 lb

So, $183lb\times \frac{1kg}{2.205lb}=83kg$

And, weight of Brandon measured at the health club = 85.0 kg

As, the weight at the health club is more than the previous measured weight. So, Brandon has gained weight.

• For b:

We are given:

Amount of diced onions a recipe calls = 125 g

Mass of 1 onion = 4 oz

Converting the mass of 1 onion to ounces, we use the conversion factor:

1 oz = 28.35 g

So, $4oz\times \frac{28.35g}{1oz}=113.4g$

To calculate the number of onions, we use the equation:

$\text{Number of onions}=\frac{\text{Mass of onion a recipe calls}}{\text{Mass of 1 onion}}$

$\text{Number of onions}=\frac{125g}{113.4g}=1.1\approx 1$

Hence, the number of onions required is 1.
