255 hours / 85 hours = 3.
This means that the bacteria will double in size 3 times.
900,000 × 2 = 1,800,000
1,800,000 × 2 = 3,600,000
3,600,000 × 2 = 7,200,000
After 255 hours, the colony of bacteria will be 7,200,000
Answer:
Step-by-step explanation:
Figure out the area of the sponge A= ab Altitude or height given is 1 inch
Base is 3 inches so Area is 3 square inches.
Total area of the design is given as 66 a square inches. Divide total area by area of the sponge to see the minimum applications (assume no overlap)
66÷3 = 22
For the drawing, you need to reproduce the sunburst by drawing the shape of the sponge in a circle filled in and and the rays coming off. Plan ahead.
Save 11 "hits" for the rays, so you have 11 to make the center circle. Start in the middle and work outward.
The answer is b
2/5 times 2/5 is equal to 4/25
these events don’t have relation so they are independent
Answer:
-8 <_ x < -3
-7 <_ y < -2
Step-by-step explanation:
closed dot means it includes that number so in this case x is least than or equal to -8 and open dot means it doesn't include that value so x is less than -3 and does NOT include -3
and for the y value it's pretty self explanatory if u just count it (i might be off by a little cuz the photo quality is kinda fuzzy but i hope u get the gist!)
Answer: -2, which is choice C
Work Shown:
The slope is -2
