The answer is Beryllium atom has a larger radius by 2 times.
Nitrogen atom: 5.6 × 10⁻¹¹ = 5.6 × 10⁻¹⁻¹⁰ = 5.6 × 10⁻¹ × 10⁻¹⁰ = 0.56 × 10⁻¹⁰
Beryllium atom: 1.12 × 10⁻¹⁰
Since 1.12 is bigger than 0.56, then the radius of beryllium atom is larger of the radius of nitrogen atom. Let's see by how many times:
1.12 × 10⁻¹⁰ : 0.56 × 10⁻¹⁰ = 1.12 : 0.56 = 2
Answer:
He needs 0.075 lbs of sugar and 4.925 lbs of water.
Step-by-step explanation:
Let x lbs be the amount of sugar in the syrup. Then 5-x lbs is the amount of water in this syrup.
Note
5 lbs - 100%
x lbs - 1.5%
Write a proportion:
Cross multiply:
So, he needs 0.075 lbs of sugar and 5 - 0.075 = 4.925 lbs of water.
Answer:
72
Step-by-step explanation:
\
Fig 1 = l x b = 3 x 12 = 36
Fig 2 = l x b = 6 x 6 = 36
Area if whoe fig = 36+ 36 = 72
iI hope im right !!
Rewrite in quadratic form:
x² + 13x + 4 = 0
The best approximations, given the options, are 0 and -13
The actual solution is -0.3 and -12.7
