Answer:
x = 96
y = 66
Step-by-step explanation:
The sum of interior angles of the given shape is 360:
x + y + 123 + 75 = 360
x + y + 198 = 360 subtract 198 from both sides
x + y = 162
The angle with the measure 114 and angle y are supplementary so their sum is 180
y + 114 = 180
y = 66 since x + y = 162 we can use this to find the value of x
x = 162 - 66
x = 96

Answer:
The answer is 14.46%
Step-by-step explanation:
Given is : A culture containing 20 bacteria multiplies to 117,360 in one minute.
Let A0 be initial bacteria count = 20
Let A be final bacteria count = 117360
Time = 60 seconds
R = rate
Formula to be used = ![A=A0e^{rt}](https://tex.z-dn.net/?f=A%3DA0e%5E%7Brt%7D)
![117360=20e^{r*60}](https://tex.z-dn.net/?f=117360%3D20e%5E%7Br%2A60%7D)
![5868=e^{60r}](https://tex.z-dn.net/?f=5868%3De%5E%7B60r%7D)
Taking log function (ln) on both sides.
![ln(5868)=ln(e^{60r} )](https://tex.z-dn.net/?f=ln%285868%29%3Dln%28e%5E%7B60r%7D%20%29)
![60r=8.677](https://tex.z-dn.net/?f=60r%3D8.677)
Hence, r = 0.1446 and in percentage it is 14.46%
