Answer:
x= 46
Step-by-step explanation:
u add up the two coordinating sides 57+57(which is y)= 114
u miuns 160-114= 46
Answer:
n = 145
Step-by-step explanation:
-58 ÷ -0.4 = 145
n = 145
Answer:
169
Step-by-step explanation:
65 divided by 5 to get 13
and multiply that with 13
like this: 13x13
to get 169
Answer:
Yup its right
Step-by-step explanation:
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
