A scientist running an experiment starts with 100 bacteria cells. These bacteria double their population every 15 hours. Find how long it takes for the bacteria cells to Increase to 300. Use the formula Pị= P.25, where Po is the original number of bacterla cells, Pe is the number
after thours, and dis the time taken to double the number.
It takes
hours for the number of bacteria to increase to 300.

the answer for this question is 38

191 students play sports and ninety-seven 10th graders were surveyed.

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
