Answer:
He is correct
Step-by-step explanation:
12=100%
15 is 3 more than 12
12 divided by 3 is 4
100 divided by 4 is 25
100 + 25 = 125

<u>Answer:</u></h3>
x = 12°
<h3>
<u>Step-by-step explanation:</u></h3>
Since both lines are parallel.
Using alternate angle property!
= > Angle A = Angle B
= > 5 x - 15 = 2 x + 21
= > 5 x - 2 x = 21 + 15
= > 3 x = 36
= > x = 12
Therefore, the value of x is 12°.
Equation:
x/3 = x/8 + 2/3

Multiply thru by 24 to get:
8x = 3x + 16
5x = 16
x = 3 1/5

Answer: P(t) = 600*(1.041)^t.
Step-by-step explanation:
An exponential growth can be written as:
P(t) = A*(1 + r)^t
Where:
A = initial population = 600
r = rate of growth in decimals = 4.1%/100% = 0.041.
t = number of units of time.
Now we have a problem, we know that the growth rate is 4.1 %, but we do not know in which time units are we working.
Because is not the same if the bacteria grows a 4.1% in one day, than if the bacteria grows a 4.1% in a hour.
But that does not matter for the actual equation, because we can just define "t" as the time (like the question asks) and the equation will be:
P(t) = 600*(1 + 0.041)^t
P(t) = 600*(1.041)^t.
