  1. If Kayla has a red ribbon with length 25  9 m and piece of 5 7 m is cut from it and gave to Sania . Find how much long ribbon left with her?                                                                                                                                                                                                                      
  • Kayla has a ribbon of length = 25 9 m.
  • Part of ribbon give to Sania = 5 7 m.
  • So, the length of the ribbon left =25 9 m - 5 7 m = 175  63 = 130  63 m
  • So , the ribbon left with Kayla is 2.06 m .

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.
