House price = down payment + mortgage x number of months
430,000 = 250,000 + 2,000x where x is number of months
To find number or months solve for x
430,000 = 250,000 + 2,000x
Subtract 250,000
180,000 = 2,000x
Divide by 2,000
x = 90 months
12 months in one year
90 = 84 + 6 = 12 x 7 + 6
7 years and 6 months
I genuinely don't know what the point is of the table, where do you use it for?
Answer:
225.78 grams
Step-by-step explanation:
To solve this question, we would be using the formula
P(t) = Po × 2^t/n
Where P(t) = Remaining amount after r hours
Po = Initial amount
t = Time
In the question,
Where P(t) = Remaining amount after r hours = unknown
Po = Initial amount = 537
t = Time = 10 days
P(t) = 537 × 2^(10/)
P(t) = 225.78 grams
Therefore, the amount of iodine-131 left after 10 days = 225.78 grams
