120 grams half life at 45 days would be 60 then half life of 60 in another 45 days (90 total) should be 30 grams
Answer:
1 / 8
Step-by-step explanation:
I'm assuming that is meant to be 3/4 and 1/6...
Area = Length * Width
A = 3/4 * 1/6
A = 3 / 24
simplify the fraction to get your answer
1/5 is equal to the 20% of the trip and that took 45 minutes.
45minutes/20% of traveled distance = X minutes/ 100% travel distance
2.25 * 100= X
225= X
So if for the 1/5 or 20% of the trip lasted 3/4hour or 45 minutes. To complete the trop you need 225 minutes or 3 hours and 45 minutes or 3 3/4 hours.
Answer:
x = 4
Step-by-step explanation:
The base angles of an isosceles triangle are congruent, as shown in the figure.
Equating their measures, we have ...
∠A = ∠C
8x -7 = 25 . . . . substitute the given expressions
8x = 32 . . . . . add 7
x = 4 . . . . . . divide by 8
