Answer: D) 1/9
-----------------------------------------------------
Explanation:
There are 4 occurrences of the value "4" based on what is given in the table.
This is out of 7+5+6+4+8+6 = 36 total
Divide the two values (4 and 36) to get: 4/36 = 1/9
Answer: 2.4
Step-by-step explanation:
a²+b²=c²
3.9+b²=6.3
-3.9 -3.9
_________
b=2.4
check it:
3.9+2.4=6.3
there you go
mark brainly if this helps PLEASE.
-7!!
I checked on my calculator, since it’ll be too hard to show the work here with my phone :)
Answer:
434,470 gallons
Step-by-step explanation:
The exponential equation for the volume v remaining after t hours can be written as ...
v(t) = (initial amount)×(decay factor)^(t/(decay time))
v(t) = 500,000×(1 -10%)^(t/3)
Then after 4 hours, the remaining volume is ...
v(4) = 500,000×(0.90^(4/3)) ≈ 434,470 . . . . gallons
_____
<em>Comment on the form of the equation</em>
The decay factor is related to the decay rate by ...
decay factor = 1 - (decay rate)
and the decay time is the time applicable to that decay rate. Here, the rate is 10% every 3 hours, so the decay time is 3 hours for a decay rate of 10%.
