Answer:
Step-by-step explanation:
<u>Full surface area of the rectangular prism is:</u>
- S = 2(ab + bc + ac)
- S = 2(6*5 + 6*4 + 5*4) = 148 ft²
<u>Cost of the wallpaper:</u>
- $740 / 148 ft² = $5 per ft²
Answer:
The coefficient is 3.
Step-by-step explanation:
The coefficient is the number that is grouped with an unknown number represented by a letter.
Tax rate is 2+3/4=2.75%
Income taxable
37,500−3,300=34,200
Tax accrued
34,200×0.0275=940.5
The slope-intercept of the line is
y= -2/3x + 2
Going up 2, left 3
Change in y

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).

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.
