Answer:
16.5 hours
Step-by-step explanation:
You know the initial value (100) and the growth factor (2), along with the period associated with that growth factor (12 hours). This lets you write the exponential growth equation as ...
n = 100×2^(t/12)
For n=260, we can divide by 100 and take the log.
260 = 100×2^(t/12)
2.6 = 2^(t/12)
log(2.6) = (t/12)log(2) . . . . next, divide by the coefficient of t
12×log(2.6)/log(2) = t ≈ 16.5 . . . . hours
It will be about 16.5 hours until there are 260 bacteria present.

If I am not wrong I think Jeremy is 68" tall
The value of x+y+z = 93
<u>Explanation:</u>
<u></u>
angle 1 = 18x
angle 2 = x+y
angle 3 = 30z
In rhombus, the diagonals intersect at 90°
Therefore,
angle 1 : 18x = 90
x = 90/18 = 5
angle 2: x+y = 90
5+y = 90
y = 85
angle 3: 30z = 90
z = 90/30 = 3
Value of x+y+z = 5+85+3 = 93
Thus, the value of x+y+z = 93
Y=2 x=3 double check is at bottom but cut off
I was not sure if the x in your equation was a multiplication sign or a variable
6/7x
-1 multiplied by 3/7x times -2
And when you multiply two negatives it equals a posible so the -2 and -1 turn into a positive
