<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,
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,
To calculate the number of onions, we use the equation:
Hence, the number of onions required is 1.
