The measure of angle ABD would be 77 degrees; 132-55=77.
Answer:
6x+2y=34
6x=34-2y
x=(34-2y)÷6........1st euation
2x-7y=-27.....2nd equation
putting the value of x from equation 1st in equation 2nd we will get
2(34-2y)÷6-7y=-27
68-4y-42y=-27×6
-44y=-162-68
-44y=-230
y=230÷44
y=5.2
again putting the value of x in equation 1st
6x=34-2×5.2
x=23.6÷6
x=3.9

Given:
The growth of a sample of bacteria can be modeled by the function
where, b is the number of bacteria and t is time in hours.
To find:
The number of total bacteria after 3 hours.
Solution:
We have,
where, b is the number of bacteria and t is time in hours.
Substituting t=3, we get the number of total bacteria after 3 hours.
Number of bacteria cannot be decimal value. So, approximate the value to the nearest whole number.
Therefore, the number of total bacteria after 3 hours is about 3003.
