Answer:
1560 cubic inches
Step-by-step explanation:
18x20= 360
360x13= 4680
4680/3=1560
Answer: 4,1 read carefully
Step-by-step explanation:
First, multiply by 3 on both sides:

Divide by 7:

So,
k = 9
Answer:
An explicit representation for the nth term of the sequence:

It means, option (B) should be true.
Step-by-step explanation:
Given the geometric sequence

A geometric sequence has a constant ratio, denoted by 'r', and is defined by

Determining the common ratios of all the adjacent terms

As the ratio is the same, so
r = 4
Given that f₁ = -1/2
substituting r = 4, and f₁ = -1/2 in the nth term


Thus, an explicit representation for the nth term of the sequence:

It means, option (B) should be true.
Ok, so we know that the product of means something added, and we are given that eleven and a number are less than 53. So the equation is 11+X<53.
