X and Y are two rectangular containers. The base area of X is 30 cm2 and the
base of Y has dimensions as shown. X contained 780 cm of water and Y was
empty.
9 cm
30 cm
(a)
What was the height of the water level in X?
(b)
Sam poured some water from X into Y without spilling. After that, the
height of the water level of X was the same as that of Y. How much
water did Sam pour into Y?

srry idk

step-by-step explanation:

2 2/3 hours duhh silly

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
