Answer:
R=6.57978
also everyone add my sc- amber_hughes42
Step-by-step explanation:
we are given
I=3.8 \times 10^6
I_0=1
now, we can use formula
R=log(\frac{I}{I_0} )
now, we can plug these values
we get
R=log(\frac{3.8 \times 10^6}{1} )
Answer:
Step-by-step explanation:
sin(x°) = 4/5
x° = arcsin(4/5) ≅ 53.1°

The probability that Gina randomly selected two red marbles is 1/19
<u>Explanation:</u>
Total number of marbles = 7 + 5 + 8
= 20
The probability of getting two red marbles in the fraction form is given as:
P(first red marble) = number of red marbles / total number of marbles
P(first red marble) = 
P(second red marble) = number of red marbles after 1 white marble is removed / total number of marbles after 1 red marble is removed.
P(first red marble) = 
P(two red marbles) = P(first) X P(second)
= 
= 
Therefore, the probability that Gina randomly selected two red marbles is 1/19
In order to solve this equation, you must focus your efforts on isolating x. First, add 4x to both sides of the equation. This will eliminate it on the left and cause the equation to look like this: 35=15+4x. Next, you need to subtract 15 from both sides <span>which will eliminate it on the right and cause the equation to look like this: 20=4x. Finally, you must divide both sides of the equation by 4. Ta-da!~ This leaves you with x=5.
The answer is x=5.
Good luck and good day! c:
