Answer:
140
Step-by-step explanation:
- 143,622 bacteria present on day 15
- the bacteria doubles twice a day
that means each day backwards, the bacteria is four times less the day before
therefore:
- on day 14, the number of bacteria is 143,622 / 4
which is 35,905.5
and so on!
so:
- day 13 = 8,976.375
- day 12 = 2,244.09375
- day 11 = 561.0234375
- day 10 = 140.255859375
this rounded to the nearest whole number is
= 140 bacteria
(you can't have a part of a bacteria!)
hope this helps! :)

Answer:
Step-by-step explanation:
hello : write this expression
X² + y² + 6x – 2y+3 = 0 in the standard form
(x²+6x) +(y²-2y) +3 = 0
(x²+6x+9 -9) +(y²-2y+1 - 1) +3 = 0
(x²+6x+9) -9 +(y²-2y+1) - 1 +3 = 0
(x+3)²+(y-1)² = 7(the standard form)
but : 7 = (√7)²
<h2>the radius is :
√7</h2>
Solve for n
Simply both sides 11(n-1)+35=3n
Distribute (11)(n) + (11)(-1) + 35 = 3n
11n+-11+35=3n
Combine like terms (11n)+(-11+35)=3n
11n + 24 =3n
Subtract 3n from both sides
11n+24-3n=3n-3n
8n + 24 = 0
Subtract 24 from both sides
8n+24-24=0-24
8n = -24
Divide both sides by 8
8n = -24
8 8
n = -3
