2.15 as an equivalent mixed number

2  3/20

Step-by-step explanation:

First you would write 2.15/1 ;  Next, multiply both the bottom and the top by 100 because of the decimal placement. This gives you 215/100. Find the GCF (which is 5) and divide. This leaves you with 43/20, and when simplified, gives you 2 as the whole number and 3/20.  

answer: idk wbu

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
