First, use triangle angle sum theorem on the triangle on the right.
180-(43+57)=80
Use vertical angles theorem,
the missing angle of the triangle on left is 80 as well.
Use triangle angle sum theory again.
2x+80=180,
x=50
Answer:
what is it round what to the nearest ten what
Step-by-step explanation:
Answer:
the probability is 0.4%
Step-by-step explanation:
the probability is equal to the proportion of students of X respect to the total amount of students , assuming that each student is equally likely to be chosen, thus:
Probability = number of students of X that participate / total amount of students = number of students of X / total amount of students * number of students of X that participate / number of students of X = 0.2 * 0.02 = 0.004 (0.4%)
The reaction is:
A ( g ) + 1/2 B ( g ) → C ( g )
We will rewrite it so the coefficient in the front of C is 1:
1/2 A + 1/4 B → C
So the rate of increasing of C is 4 times faster than the decrease of B.
The rate of B:
- 1.5 · 10^(-2) M/s : 4 = - 0.375 · 10^(-2) M/s = - 3.75 · 10 ^(-3) M/s
Answer: - 3.75 ·10^(-3) M/s
The answer is scalene because they all have different side
