Answer:
y= 0.75x + -0.50
A or B is what im guessing
To get to simplest form find the greatest common factor, or the gcf, of both numbers. To do that find all of the factors and find the one with the highest value both numbers share. So 30 would have factors of 1, 2, 3, 5, 6, 10, 15, and 30, and 42 would have the factors of 1, 2, 3, 6, 7, 14, 21, and 42. Both numbers share the factors of 1, 2, 3, and 6 so the gcf is 6. Now divide both numbers by six to get your answer.
Answer: 5/7
-7/5-(-5/6)
= -7/5+5/6
=( -42+25)/30
= - 17/30
hope it helped you
Answer:
0.3
Step-by-step explanation:
1. break it down 25/75
2. the answer 1/3 not the real answer
3.turn decimal form
4. 0.3
Answer:
The volcanic eruption occurred 8,634.90 years ago.
Step-by-step explanation:
Formula used:
where,
= initial mass of isotope = x
N = mass of the parent isotope left after the time, (t) = 35% of x=0.35x
= half life of the isotope = 5700 year
= rate constant
Now put all the given values in this formula, we get
The volcanic eruption occurred 8,634.90 years ago.
