Answer:
4 1/4
Step-by-step explanation:
make improper
17/3 * 3/4 then multiply a across ( Numertors multiply numurators, denominator multplies denominator)
=51/12 then reduce
Answer:
-1 and 5
-2 and 6
-4 and 8
<u><em>They all give the same total i.e. 4</em></u>
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
5/8+ 1/4+ 1/2
= 5/8+ 2/8+ 4/8
= 11/8
= 1 3/8
The final answer is 1 3/8~
