Answer:
1. 15
2. 8
Step-by-step explanation:
The two sequence are geometric progression GP, because they follow a constant multiple (common ratio)
The nth term of a GP is;
Tn = ar^(n-1)
Where;
a = first term
r = common ratio
For the first sequence;
The common ratio r is
r = T3/T2 = 540/90 = 6
r = 6
T2 = ar^(2-1) = ar
T2 = 90 = ar
Substituting the values of r;
90 = a × 6
a = 90/6
a = 15
First term = 15
2. The sam method applies here.
Common ratio r = T3/T2 = 128/32 = 4
r = 4
T2 = ar^(2-1) = ar
T2 = 32 = ar
Substituting the values of r;
32 = a × 4
a = 32/4
a = 8
First term = 8

Answer:
V=210 square inches
Step-by-step explanation:
Volume formula for a rectangular prism is V=lwh
So Volume=Length x Width x Height
V= 14 x 10 x 1.5
V=210 square inches
Answer:
120 meters
Step-by-step explanation:
Bob's land is a rectangle, so it has 2 long and 2 short sides. The Long side is 40 meters long, and the short side is 20 meters long.
Let's add them: 40 + 20 = 60 meters
Since we have 2 of those sides, we will multiply it by 2 which we can demonstrate as
60 meters * 2 = 120 meters
We know that,
Interest, I =
Where, P = Principal = $1300
R = rate of interest = 9% annually =
%
T = Time = 1 month
So, I =
![\frac{1300×[tex] \frac{9}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1300%C3%97%5Btex%5D%20%5Cfrac%7B9%7D%7B12%7D%20)
×1}{100} [/tex]
= $9.75
Interest paid per month is
$9.75
