Answer:
Number of term = 48
Step-by-step explanation:
GIven:
Arithmetic progression
2,5,8..
Total sum of Arithmetic progression is 392
Find:
Number of term
Computation:
First term a = 2
Difference d = 5 - 2 = 3
Sn = [n/2][2a + (n-1)d]
392 = [n/2][2(2) + (n-1)3]
392 = [n/2][4 + 3n - 3]
784 = [n][1 + 3n]
784 = n + 3n²
3n² + n - 784
n = 48 , n = -49
Number of term = 48
Answer:
z ≤ 8
Step-by-step explanation:
z is less than or equal to 8
z is no more than 8
Answer:
12 hours
Step-by-step explanation:
Ser up your equation 35 = 5 + 2.50x
Subtract 5 from both sides
30 = 2.50x
Divide both sides by 2.50
<span>Each piece length will be 1/8 part of the whole piece, so as the total length is 9 yards then we will have that the lengh of each piece is one and eighth yard.
The division expression is as follows:
Piece length = 9 * 1/8 = 9/8 = (8+1)/8 = 8/8+1/8 = 1 + 1/8 = 1 + 0.125 = 1.125 yards</span>
