Answer:
The next number of the series 0, 1/3, 1/2, 3/5, and 2/3 is 5/7
Step-by-step explanation:
The given numbers are;
0, 1/3, 1/2, 3/5, and 2/3
The number sequence is formed adding to each (n - 1)th term to get the nth term number in the sequence, with the first term equal to 0, as follows;
For the 2nd term, the (n - 1)th term is 0, and n = 2, gives;
The
For the 3rd term, the (n - 1)th term is 1/3, and n = 3, gives;
For the 4th term, the (n - 1)th term is 1/2, and n = 4, gives;
For the 5th term, the (n - 1)th term is 3/5, and n = 5, gives;
For the next or 6th term, the (n - 1)th term is 2/3, and n = 6, gives;
The next number of the series 0, 1/3, 1/2, 3/5, and 2/3 = 5/7.
Answer:
I have solved the question in the picture in two different ways : simplification and factorisation I hope you find it useful bye:)
Total surface area equals area of 5 rectangular faces + 2 pentagonal faces
Area of 5 rectangular faces
Area of 2 pentagonal faces can be found by drawing 5 isosceles triangles with height as shown in the diagram and multiply the result by 2.
The toatal surface area is
The correct answer is A
