If the value of n nickets plus d dimes is c cents, what is n in terms of d?

What are the values of n and l for 4d orbitals ?

In an arithmetic series, the sum of the first 2n terms is half the sum of the first 3n terms. If a = 12 and d = 3, find the value of n.

The table above gives the average weight, expressed in both grams and drams, of three types of modern U.S. coins. IF a bag of coins weighing 225 grams is filled with p pennies,n, nickels, and d dimes, which of the following expresses d in terms of n and p?

If the sum of m terms of an A.P. is the same as the sum of its n terms, then the sum of its (m+n) terms is (a). m n (b). -m n (c). 1//m n (d). 0

If the sum of m terms of an A.P. is the same as the sum of its n terms, then the sum of its (m+n) terms is (a). m n (b). -m n (c). 1//m n (d). 0

If the sum of n terms of an A.P. is 2n^2+5n ,\ then its nth term is a. 4n-3 b. 3n-4 c. 4n+3 d. 3n+4

If in the expansion of (a+b)^n\ a n d\ (a+b)^(n+3) , the ratio of the coefficients of second and third terms, and third and fourth terms respectively are equal, then n is a. 3 b. 4 c. 5 d. 6

If the sum of n terms of an A.P.is 2n^(2)+5n then its nth term is 4n-3 b.3n-4 c.4n3 d.3n+4

For a positive integer n, define d(n) - the number of positive divisors of n. What is the value of d(d(d(12))) ?

In an A.P. with first term 'a' and the common difference d(a, d!= 0) , the ratio 'rho' of the sum of the first n terms to sum of n terms succedding them does not depend on n . Then the ratio (a)/(d) and the ratio 'rho' , respectively are
