1. I am currently $13$ times as old as my granddaughter. Next year, I will be $11$ times as old as my granddaughter. How old am I now?

2. Gina has $15$ dollars more than twice as much money as her sister Maria. If Gina gives Maria $30$ dollars, then Gina will have half as much money as her sister. How many dollars does Gina have?

3. A rectangular plot of land has dimensions $x$ meters by $y$ meters. The plot of land is $216$ square meters in area. Farmer Ted encloses the rectangle with a fence and then divides the rectangle into two equal parts with another fence of length $x$ meters parallel to one of the sides. In terms of $x$ and $y,$ what is the total length of fence used? Describe the length of the fence used in terms of only one variable.

21/58.

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
