Answer:
diameter ≈15.6
Step-by-step explanation:
To solve this;
volume of a sphere = 4/3 πr³
From the question given;
volume of the sphere = 268
lets substitute and solve for r
volume of sphere = 4/3 πr³
268 = 4/3 × 3.14 × r³
268 =4.19 × r³
Divide both-side of the equation by 4.19
268/4.19 = r³
63.96 = r³
Take the cube root of both-side
∛63.96 = r
7.8 ≈ r
but diameter = 2r = 2×7.8 =15.6
Answer:
Therefore all numbers that end with five and are greater than five are composite numbers. The prime numbers between 2 and 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97.
Step-by-step explanation:
It will be 24.4

Answer:
Step-by-step explanation:
let 25 % copper=x kg
75 % copper=(100-x) kg
0.25 x+(100-x)*0.75=100*0.61
25x+7500-75 x=6100
-50 x=-1400
50 x=1400
5x=140
x=28
25 % of Copper=28 kg
75 % of Copper=100-28=72 kg
