You just multiple my guy. 2:3 is like 2/3. What is 2/3 of 39
39*2/3 = 26
23.4375 or 24.0 is the bacteria count after 6 hours.
You originally start out with 28 marbles. each marble has a number out of 28 to create a percentage. 21/28 or 75% signifies red, 4/28 or about 14% is white and 3/28 or about 11% is gray. add white and gray, which is 7/28 combined or 25% together. multiply by number of times the process is completed, which is 112 and the final answer is 28
Answer: b(-2, 2) c(4,2) d (-6,7)
Step-by-step explanation:
The formula for reflecting over x axis is (x,y) - > (x,-y)
the current points are
-2,-2
4, -2
-6, -7
which turn into -2, 2
4, 2
-6,7
When you divide, you're doing the oposite of multiplication. To know that your partical answer is going to be in the hundreds place is you follow the pattern.
2874/3=958
you take the 3 and you divide it by the last two didits of the number given (28) and that'll get you into your hundreds place.
Hope this helped! :-)
