A blue whale gains 2.3 tons a month for the first year of life. If a blue whale weighed 15 tons at birth, how much will it weigh at 6 months of age?

To find the weight of the blue whale at 6 months of age, we need to calculate how much weight it gains in 6 months and then add it to its initial weight.
The blue whale gains 2.3 tons a month for the first year of life, so in 6 months, it would gain (2.3 tons/month) * (6 months) = 13.8 tons.
To find the weight at 6 months, we add the weight gained to the initial weight:
Weight at 6 months = 15 tons + 13.8 tons = 28.8 tons
Therefore, the blue whale will weigh 28.8 tons at 6 months of age.
To solve this problem, we can break it down into steps:
1. Determine how much weight the blue whale gains per month for the first year. It gains 2.3 tons per month.
2. Calculate the weight gained in 6 months. Since the blue whale gains 2.3 tons per month, in 6 months it will gain: 2.3 tons/month * 6 months = 13.8 tons.
3. Add the weight gained to the initial weight of the blue whale. The blue whale weighs 15 tons at birth, and it gains 13.8 tons in 6 months. Therefore, at 6 months of age, the blue whale will weigh: 15 tons + 13.8 tons = 28.8 tons.
So, the blue whale will weigh 28.8 tons at 6 months of age.
To solve this problem, we need to calculate the weight gain of the blue whale in 6 months. Given that the blue whale gains 2.3 tons per month for the first year, we can calculate the weight gain for 6 months.
First, we need to calculate the weight gain for the first year. Since there are 12 months in a year, the weight gain for the first year can be calculated as:
Weight gain for the first year = 2.3 tons/month * 12 months = 27.6 tons
Now, we need to find the weight gain for 6 months. Since the weight gain is constant at 2.3 tons per month, we can calculate the weight gain for 6 months as:
Weight gain for 6 months = (2.3 tons/month) * (6 months) = 13.8 tons
Finally, we can find the weight of the blue whale at 6 months of age by adding the weight gain to its birth weight:
Weight at 6 months = Birth weight + Weight gain for 6 months
Weight at 6 months = 15 tons + 13.8 tons
Weight at 6 months = 28.8 tons
Therefore, the blue whale will weigh 28.8 tons at 6 months of age.
