Nitrogen Radius = 5.8 x 10⁻¹¹ m
Beryllium Radius = 1.12 x 10⁻¹⁰ m
Let's find the quotient of N/Be :
(5.8x10⁻¹¹)/(1.12x10⁻¹⁰). But 10⁻¹¹/10⁻¹⁰ = 10⁽⁻¹¹⁺¹⁰⁾ = 10⁻¹ = 1/10 = 0.1
→ (5.8/1.12).(0.1) = 0.58/1.12 = 0.518.
Conclusion: the radius of Be is almost double than the radius of N

Answer:
25% probability that you complete the course
75% probability that you do not complete the course
Step-by-step explanation:
If there are a total of 4 individuals entering the race and only one is able to complete the course then the probability that you will complete the course would be
1/4 = 0.25 or 25%
This is because you only represent 1 out of the 4 total participants. The opposite would be the case to calculate the probability that you will not complete the course since there are three other candidates with that could have completed it, therefore...
3/4 = 0.75 or 75%
Answer:
k = 2
Step-by-step explanation:
the dilation k is the scale factor. A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object. To find the scale factor k, we will compare the original points with their transformation
Point R is at (-1,2), and R' is at (-2,4).
divide the ys: 4/2 =2
divide the xs: -2/-1 =2
therefore the scale factor is 2
