Answer:
Year 2034
Step-by-step explanation:
In 2000, 64% had one or more pets
<em>Since decreasing at 1% per year, we can say:</em>
<em>In 2001, 63%</em>
<em>In 2002, 62%</em>
<em>In 2003, 61%</em>
<em>In 2004, 60%</em>
<em>And so on</em>
<em />
To go to 30% from 60% in 2004, we would need to decrease 60 - 30 = 30%, and that will occur after 30 more years. So that would be the year
2004 + 30 = 2034
So, year 2034

Step-by-step Solution for Part-a:
<u>We know that:</u>
- Row-1: 20 seats
- Row-2: 20 + 11
- Row-x: 20 + (11x - 11)
Since the number of rows in rows x is 20 + (11x - 11), the formula to calculate the number of seats in each row is 20 + (11x - 11).
<h3>________________________________________________</h3>
Step-by-step Solution for Part-b:
<u>We know that:</u>
- y rows = 174 seats
- Obtained rule from part-a: 20 + (11y - 11)
<u>Solution:</u>
- 20 + (11y - 11) = 174 rows
- => 20 + 11y - 11 = 174 rows
- => 9 + 11y = 174 rows
- => 11y = 174 - 9 rows
- => 11y = 165
- => y = 165/11
- => y = 15
Hence, the row which has 174 seats is row 15.

Answer:
6
Step-by-step explanation:
Follow the PEMDAS rule.
Parentheses
Exponent
Multiplication
Division
Addition
Subtraction
By following that rule, you know that you have to take care of the exponent first. 1/2 to the fourth power is 1/16. Then the next step in pemdas is to multiply that with 48, which is 3. The you subtract 3 from 9.
