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
Apologies, but there is no map...?
A point doesn't have slope. Once you have TWO points, then the line between them has a slope.
The slope is (how far the line rises from one point to the other) divided by (the level distance between them).
Answer:
25
Step-by-step explanation:
2 out of 12 means also 1 out of 6.
so, a ratio of 1:6 or a factor of 1/6.
150 × 1/6 = 150 / 6 = 25
so, we expect that out of the 150 sold cars 25 have been red.
Answer:
130
Step-by-step explanation:
2x+5x+5=180
7x+5=180
7x=175
x=25
5(25)+5=125+5=130
