Please help! Pre-algebra problems that i can't figure out: 1: Elijah's workout at the gym consists of just the elliptical and treadmill. After burning 450 calories on the elliptical machine, Elijah switched to the treadmill. If he is burning 12.5 calories per minute on the treadmill, find the total number of calories he will have burned during his workout if he spends 30 minutes on the treadmill.

2: A car that was originally worth $29,500 depreciates at a rate of $2,500 per year. Find the value of the car after six years

im with everythinglos so yeahhhhh

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

a 90 degree rotation across the the origin followed by a reflection across the x-axis.
