<u>Total number of seats</u> = (8 rows) x (15 seats per row) = <u>120 seats</u>.
<u>Number of occupied seats:</u>
(5 rows) x (15 seats per row) = 75 seats
people sitting alone in next row = 3 seats
Total occupied = (75 + 3) = <u>78 seats</u>
Empty seats = (total seats) minus (occupied seats) = 120 - 78 = <u>42 empties</u>
Answer: 
Step-by-step explanation:
One-sixth of n is n/6.
One-fifth of g is g/5.
The sum means to add, so the expression is .
So the angles inside the triangle add up to 180
95+25+x=180
120+x=180
subtract 120 from both sides
x=60
answer is 60 degrees
Answer:
x = 2/3
Step-by-step explanation:
sin²30° + cos²30° + x.tan²60° = cot²30°
=> (1/2)² + (√3/2)² + x(√3)² = (√3)²
=> 1/4 + 3/4 + 3x = 3
=> 3x = 2
=> x = 2/3
The answer is w*v*1/2*6. All you did is rearrange the numbers. (moved the 6 to the other side, which does not affect anything)
