725 is equal to (number of rows)*(number of seats per row)
r = s-4
725 = (s-4)s
s^2-4s-725 = 0
Factoring: (s-29)(s+25) = 0
Thus there are 29 seats per row, and 25 rows.
Answer:
1 gogle liters
Step-by-step explanation:
The amortization formula can be used to figure this.
... A = P(r/n)/(1 -(1 +r/n)^(-nt))
where A is the monthly payment, P is the amount borrowed, r is the annual interest rate, n is the number of times per year interest is compounded, and t is the number of years.
Fill in the given information, and solve for P (in either order).
... 821.69 = P(.065/12)/(1 - (1 +.065/12)^(-12*30)) ≈ 0.00632068023P
... P ≈ 130,000.25 . . . . . divide by the coefficient of P
Rounded to the nearest dollar, you borrowed $130,000.

Answer:
C. x = 3cm
Step-by-step explanation:
The formula for volume of a triangular prism is
<u>V = base * height</u>
x in this case equals height, and the base is the area of the triangular base, which is
<u>A(triangle) = 1/2 b*h</u>
= 1/2 7*10 = 35 square centimeters
Plug this back into our formula:
V = base * height
105 = 35x
Solve for x.
105/35 = x
<u>C. x = 3 cm</u>
