You have to add all the containers together in order to get the total weight.
3+5
8+3.5
11.5+2.75
14.25
So, the total weight of the four containers is 14.25 pounds.

11. The completion of a chemical reaction is expressed by the equation y = 300 - 4x - XP, where y is

alina1380 [7]

Answer:

The reaction ca occur at 10 degree Celsius or -14 degree Celsius.

Step-by-step explanation:

We are given the following in the question:

The completion of a chemical reaction is expressed by the equation

$y = 300 - 4x -x^2$

where y is the number of seconds needed to complete the reaction and x is the temperature in degrees Celsius at which the reaction occurs.

We have to find the temperature at which the reaction occurs, if the completion time of reaction is 160 seconds.

Putting y = 160

$160 = 300 - 4x -x^2\\x^2 + 4x - 140 = 0\\x^2 + 14x -10x -140 = 0\\x(x+14)-10(x+14)=0\\(x-10)(x+14) = 0\\(x-10) =0, (x+14) =0\\x = 10, x = -14$

Thus, the reaction ca occur at 10 degree Celsius or -14 degree Celsius.
