Answer:
C
Step-by-step explanation:
There is a common ratio between consecutive term in the sequence, that is
÷ 
= 3 ÷ = 30 ÷ 3 = 300 ÷ 30 = 10
This indicates the sequence is geometric with n th term
= a
where a is the first term and r the common ratio
Here a = and r = 10 , thus
= 
= 
× 
= 3 × 
×
= 3 × 
Thus
= 3
→ C
Answer:
4y + 3
Step-by-step explanation:
An equilateral triangle has three sides of equal length.
The length of each side is 1/3 of the perimeter.
(12y + 9)/3 = 12y/3 + 9/3 = 4y + 3
Answer: 4y + 3
Answer:
$11.5
Step-by-step explanation:
Add all of them together
Sonia saves a lot of water. To figure this out, you plug the number 8 into the equation, replacing it with the variable x. y = 3(8). Therefore, y=24. To find out how much water she saves, you have to also figure out how much water she was using for 8 minutes with the other shower head, the one that wastes the water. Since it dispenses 12 gallons per minute, you multiply that by 8 minutes and get 96. Subtract 24 from 96 and get 72. Which I think is your answer. Then again, I'm in high school so I most likely am wrong.
