John earns $180 for landscaping 3 yards how much will he was for landscaping 8 yards

Hi!

We will solve this using ratios, like this:

$180 for landscaping 3 yards

$x for landscaping 8 yards

x = (180*8)/3

x = 1440/3

x = 480

He would earn $480 for landscaping 8 yards.

Hope this helps!

if he landscapes 3 yards for $180 and then he landscapes 8 yards then he will get $366 for all of the yards combined

Step-by-step explanation:

                             x  6

180                   3|

180                         180

+                       18

360                          00

hope this helps

(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
