Answer:
0.3453 grams
Step-by-step explanation:
to find the amount of days in 6 weeks, you multiply 6 and 7 which will get you 42. Then 42/4 is 10.5. This means it will go through 10 full half-lifes. you divide 500 by 2 10 times and 0.3453 g is the closest answer.
Just go one point at a time on your graph:
What does y equal when x is zero?
When x is 1?
When x is 2?
That's how you plot a graph.
Answer:
24.997 cm
Step-by-step explanation:
Find the diameter:
7(2) = 14 cm
Find the circumference:
C = 
C = 
C = 43.988
Divide the circumference by 4:
43.988/4 = 10.997
(This is the length of the curved side)
Add length to the other 2 sides:
7 + 7 + 10.997 = 24.997
Answer:
270 miles
