Brandon is traveling in France. He weighs himself at a health club because he is concerned that he has eaten too many croissants

anastassius [24]

<u>Answer:</u>

<u>For a:</u> Yes, he has gained weight.

<u>For b:</u> The number of onions required is 1.

<u>Explanation:</u>

<u>For a:</u>

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.

<u>For b:</u>

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.
