126 divided by 7 equals 18
18 m
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
You add the base and to sides which will equal 10 5/12
Answer:
B
Step-by-step explanation:
B is the only answer that has the same numbers as the figure included. Triangle side size does not change in a reflection, rotation, or translation.
Hope this helps! :)
Answer:
(a) 94. (b) 85
Step-by-step explanation:
(a). the perimeter = 2l +2w ; l - length and W - width
: . 2l + 2(56) = 300
2l = 300 - 112
l = 188/2 =94m
(b) area = Lxw
8245 = 97w
w = 8245/97
= 85m
