Answer:
5,120 bacterias
Step-by-step explanation:
Given the amount of bacteria after x hours modelled by the equation:
f(x) = 20(2)^x/12
Note that x is in hours not days
To calculate the number of bacteria that will be contained within the culture after 4 days, we will first convert 4days into hours since x is in hours.
24hours = 1day
xhours = 4days
x = 24×4
x = 96hours
Substituting x = 96 into the equation
f(96) = 20(2)^96/12
f(96) = 20(2)^8
f(96) = 20×2^8
f(96) = 20×256
f(96) = 5,120
The number of bacteria that will be contained after 4days is 5,120bacterias
Answer:
∠ 1 = ∠ 2 = 75°
Step-by-step explanation:
The sum of the 3 angles in Δ CDE = 180°
sum the angles and equate to 180°
∠ 1 + 38° + 67° = 180°
∠ 1 + 105° = 180° ( subtract 105° from both sides )
∠ 1 = 75°
∠ 1 and ∠ 2 are vertically opposite angles and are congruent , so
∠ 2 = 75°
Answer:

Answer:
The Greatest Common Factor is 2
Answer: x= 10
Step-by-step explanation: distribute: 4(2x+2)=88
8x+8=88
Subtract 8 from both sides
8x= 80
Divide both sides by 8
X=10
