You find 12 coins under the couch. every coin is either a nickel or a penny, and they add up to a total of 23 cents. how many of each type of coin do you have? let x represent the number of pennies and y represent the number of nickels.

c. (3,2,6) is the answer.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

to complete this square you have to rotate about the origin 270 degrees clockwise.

(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
