Heidi is building a stone path in her garden. It needs to be between 8 feet and 812 feet long. Drag stones into the box that she can place end-to-end to create a path of the correct length.
1 5/8, 2/3, 3/5, 1 1/4

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

(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

60: 45 =12: 9 =4: 3 so the answer is 4: 3
