The common ratio is 28/7 = 4.
The formula for the n-th term is
.. an = 7*4^(n -1)
The 9th term is
.. a9 = 7*4^(9 -1) = 7*4^8
.. = 7*65,536
.. = 458,752
The theater has more floor seats since if for every one balcony seat there is 20 floor seats, that means there are more floor seats. Picture this: You have one rubber band in one hand, and 20 in the other. Double that for each hand (have 40 in one hand and 2 in the other) Which hand has more? The hand with 40.
Answer:
9/19
Step-by-step explanation:
if 20 students are boys, then the remaining students are girls. 38-20 = 18
There are 18 girl students.
18/38 can be simplified to 9/19
Yes. The two smaller squares have a sum of 169 which is the value of the larger square.
a^2 + b^2 = c^2
25 + 144 = 169
It can be done. Notice the figure below shows you how to arrange the squares to give the answer of a^2 + b^2 = c^2
