Answer:
sum of 22nd = 1,428.05
sum of 23 to 40 is 932.53
Step-by-step explanation:
A(n)=20(1.1)^n-1
20 is the first term or a1
1.1 is the common ratio or r
A(22) = 20(1.1)^22-1
22nd term = 20(1.1)^21
22nd term = 148.00
sum of geometric sequence
formula
Sn = a1(1-r^n)/1-r
Sn = sum
a1 = first term
n = number of term
r = constant ratio
sum of 22nd = 1,428.05.
23 to 40 is 17 terms
Sequence: 23, 25.3, 27.83, 30.613, 33.6743, 37.04173, 40.745903 ...
The 17th term: 105.684378686
Sum of the first 17 terms: 932.528165548

$21.21 × 6 = $127.26
$127.26 ÷ 7 = $18.18 cost of 1 pillow at Jenson's.
You multiply the cost of the pillow at Harrison's, $21.21, by the amount of pillows you can buy at Harrison's, 6.
Then divide the answer by the amount of pillows you can buy at Jenson's, 7. The final answer is the cost of 1 pillow at Jenson's.
Answer:
Rs 2,500
Step-by-step explanation:
He has spent Rs1850 + Rs150 = Rs2000
if Rs2000 = 100%
X = 125%
By cross multiplication, we get;
100x = 2000 * 125
x = 250000/100
x = Rs 2,500
Answer:
= 17 v^2 + 7v + 11
Step-by-step explanation:
Given that:
= (8v^2+6v+5)+(9v^2+v+6)
by removing brackets
= 8v^2 + 6v + 5 + 9v^2 + v + 6
Addin like terms:
= (8v^2 + 9v^2) + (6v + v)+ (5 + 6)
= 17 v^2 + 7v + 11
I hope it will help you!
