A rectangular auditorium seats 1344 people. The number of seats in each rows exceeds the number of rows by 20. Find the number o
Tasya [4]
Let the number of rows be x

rows = x
seats in each row = x + 20

total seats = 1344
x (x + 20) = 1344
x^2 + 20x - 1344 = 0
(x + 48)(x - 28) = 0
x = -48  (rejected, answer cannot be negative) or x = 28

Therefore,
x = 28 
x + 20 = 48


Check:
Row = 28
Numbers of seat per row = 28 + 20 = 48
28 x 48 = 1344 (Correct)
 
Ans:There are 48 seats per row

Consider a circle with a diameter of 5 centimeters. Which equation shows how the relationship between the circumference and the
mrs_skeptik [129]

Answer:

The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π =  \frac{C}{5} ⇒ answer C

Step-by-step explanation:

In any circle there is a constant ratio between the circumference of the circle and its diameter

This constant ratio is called π

∵ The formula of the circumference of a circle is C = π d,

    where d is the diameter of the circle

- Divide both sides by d

∴ \frac{C}{d} = π

- Switch the two sides

∴ π =  \frac{C}{d}

∵ The diameter of the circle is 5 centimeters

∴ π =  \frac{C}{5}

The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π =  \frac{C}{5}
