If you're talking about the books in between, it will/be 20 books
To solve this problem, we can use a simple addition. If you have the 11th book from the left and the 10th book from the right, the position of the books overlap only if there are fewer than 21 books in total. Since this is not stated in the problem, we operate under the assumption that these positions do not overlap. Hence, we have 10 books to the left of the 11th book and 9 books to the right of the 10th book since we're including the book at each of these positions themselves when counting from each end. Thus, we can calculate the total number of books on the shelf by summing these amounts with the books in between, which is 1 (since the positions do not overlap).
Total number of books = (Number of books to the left of the 11th book) + (Number of books to the right of the 10th book) + 1 = 10 (to the left of the 11th) + 9 (to the right of the 10th) + 1 (11th book or 10th book itself) = 20 books in total on the shelf.
There are 20 books on the shelf in total. This includes 10 books to the left of the 11th book and 9 books to the right of the 10th book, with one overlapping book counted in between. Therefore, we add them together: 10 + 9 + 1 = 20 books.

○ Reproduksi adalah proses biologis yang memungkinkan makhluk hidup menghasilkan keturunan.Berikut adalah cara reproduksi pada manusiaReproduksi pada Manusia:1. Reproduksi Seksual: Proses reproduksi yang melibatkan pertemuan antara sel sperma (dari laki-laki) dan sel ovum (dari perempuan) untuk membentuk zigot.2. Hubungan Seksual: Proses reproduksi seksual pada manusia melibatkan hubungan seksual antara laki-laki dan perempuan, di mana sperma dari laki-laki bertemu dengan ovum dari perempuan.Proses Reproduksi:1. Pembentukan Sel Reproduksi: Sel sperma dan ovum diproduksi oleh tubuh laki-laki dan perempuan melalui proses yang kompleks.2. Pertemuan Sel Reproduksi: Sel sperma dan ovum bertemu dalam saluran reproduksi perempuan, biasanya dalam tuba falopi.3. Pembuahan: Sel sperma membuahi sel ovum, membentuk zigot.4. Perkembangan Embrio: Zigot berkembang menjadi embrio, yang kemudian berkembang menjadi janin.5. Kelahiran: Janin lahir sebagai bayi setelah proses kehamilan yang normal.
