Murljashka [212]
The total amount that Chang will received from his wages is the product of his hourly wage times the number of hours he has worked (n). His total savings should not be less than $125. The equation that best describes the situation is, 
                                    45 + 7n ≥ 125
Solving for n in the inequality gives an answer of n≥11.42 hours. Thus, he needs to work for at least 12 hours.

the school that imani goes to is selling tickets to a spring musical. on the first day of ticket sales the school sold 8 adult t
9966 [12]
If we let x and y represent the prices of adult and child tickets, respectively, then we can write two equations based on the daily sales.
  8x +5y = 108
  x +14y = 67

A graphing calculator shows the solution of these equations to be
  (x, y) = (11, 4)

The price of an adult ticket is $11.
The price of a child ticket is $4.

Two sides of a triangle are 7 m 7 m and 12 m 12 m in length and the angle between them is increasing at a rate of 0.06 rad/s 0.0
gayaneshka [121]

Answer:

1.26 m^2 / s.

Step-by-step explanation:

The area A of the triangle = 1/2*7*12 sin x  = 42 sin x where x  is the angle between the lines.

Relation between the rates is

dA/dt  + dA/dx * dx/dt

We are given that dx /dt = 0.06 rad/s.

A = 42 sin x

dA/dx = 42 cos x

So dA/dt = 42 cos x * 0.06

When x = π/3  ( I am assuming that π 3 means π divided by 3 ):

dA/dt = 42 cos π/3 * 0.06

= 1.26 m^2/s.
