A culture started with 6,000 bacteria. After 6
aivan3 [116]

Answer:

9,400 bacteria at Hour 17.

Step-by-step explanation:

If at

Hour 0, it was at 6,000 bacteria then at

Hour 6, it would be at 7,200 bacteria

That means in 6 hours, the bacteria has grown by 1,200

Let's use a ratio:

hours : bacteria

   6     :   1,200

   1      :     200

  17     :   3,400

Now after 17 hours, 3,400 new bacteria has joined our group of 6,000

6000+3400=9400

9,400 bacteria should be present at Hour 17

the variable z is directly proportional to x. when x is 6, z has the value 18. what is the value of z when x = 10 the variable z
nikklg [1K]
Z\alpha x
Z=kX
When x=6, z=18,
Finding value of z,
18=k*6
k=3
Z=3X
when x=10,
Z=3*10
Z=30

Part B;
Z\alpha  \frac{1}{x}
z=\frac{a}{x}
Where x is a constant of proportionality,
when x=3, z=2
2=\frac{a}{3}
a=3*2
a=6
When x is 13,
Z=\frac{6}{13}
