This equation shows how Rita's video game score is related to the number of coins she collects. p = 20c The variable c represents the number of coins she collects, and the variable p represents the total points she scores. How many coins does Rita have to collect to score a total of 20 points?

blank coins

1 coin

Step-by-step explanation:

Given that c is number of coins, p the points collected and 20 is the constant.

-The equation for total points is p=20c, therefore, we calculate the number of coins as:

#Hence, Rita only has to collect 1 coin to earn 20 points.

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
