Answer:
n = 24
Step-by-step explanation:
From the question,
The formula for the sum of the term in an AP is given as
Sₙ = n(a+L)/2.................. Equation 1
Where Sₙ = sum of the nth term, n = number of term, a = first term, L = last term.
make n the subject of the equation
n = 2Sₙ/(a+L)................. Equation 2
Given: Sₙ = 420, a = 4, L = 31
Substitute these values into equation 2
n = (2×420)/(4+31)
n = (840)/35
n = 24.
Hence, n = 24
There are seven digits in the number 6666666. With commas separating the values, it would be 6,666,666, which is six million six hundred sixty six thousand six hundred sixty six.
Answer:
s=33.3333
Step-by-step explanation:
200=5s -(100+2s)
200= 5s -100 -2
100= 3s
s= 33.333
P ≤ 6, first you divide both sides by 7 so you get p ≤ 6 bc 7/7 is 0 and 42/7 is 6
In(x) =5
it's base is e
so x = e^5 is the answer
