A young sumo wrestler decided to go on a special high protein diet to gain weight rapidly he started at 90 kg and gained weight
at the consistent rate after eight months you weighed 138 kg. W represent the Summer wrestlers weight in kilograms after t
months
months
1 answer:
W = 6t+90 represent the relationship between weight and number of months.
Step-by-step explanation:
Given,
Weight of wrestler = 90 kilograms
Weight after 8 months = 138 kilograms
Let,
x be the weight gained each month.
Weight of wrestler + Number of months*Weight gained each month = Weight after 8 months
Dividing both sides by 8
Therefore, the wrestler gained 6 kilograms each month.
W = weight of wrestler
t = number of months
Total weight = Weight before diet + Weight gain each month*Number of months
W = 90+6t
W = 6t+90
W = 6t+90 represent the relationship between weight and number of months.

Answer:
22.38 g of silicone-32 will be present in 300 years.
Step-by-step explanation:
A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay and its given by
where,
= quantity of the substance remaining
= initial quantity of the substance
= time elapsed
= half life of the substance
From the information given we know:
- The initial quantity of silicone-32 is 30 g.
- The time elapsed is 300 years.
- The half life of silicone-32 is 710 years.
So, to find the quantity of silicone-32 remaining we apply the above equation
22.38 g of silicone-32 will be present in 300 years.
