I Will Number All The Answers Below, and give my best explanation :D

Jay Has 10 Tallies, When There Is 10 Tallies, Normally It Means the number 10

Madison Only Has 3 Tallies, therefore Madison has 3

Kimberly Has 7 Tallies, Which Means Kimberly has 7

7. You See Those Squares On The Graph? You Are Going to color them out

Jay Has 10 tallies, so you will will those squares out 10 times on Jays side

Madison Has 3 Tallies, so you are going to fill 3 Boxes for maddison

Kimberly Has 7, So you are going to fill Kimberly's box 7 times

8. How Many Bottles Did Kimberly Bring? She Brung 7 Bottles

9. Maddison Brough The Least Bottles, Which is 3

Hope This Helped :D

Answer:

A) y>=-1

Step-by-step explanation:

The line itself is y=-1, but it is also filled in. Therefore, we are down to either A or C as the right answer

Since (0,0) is a solution to the inequality as indicated by the shade, we know that since y=0 in the origin, 0 is greater than -1, so therefore A is the correct answer.

Answer:

Part A) distance covered by the aligned red cells is: 180000 Km

Part B) 8000000 bacteria (8 million bacteria)

Step-by-step explanation:

Part A)

Let's first find the total number of red cells that the person has in the 5 liters, knowing that there are 4,500,000 of them in a cubic millimetre:

Since 1 liter contains 1,000,000 cubic millimetres, then, in 5 liters there must be 5 times that number of cubic millimetres. That is a total of 5,000,000 cubic millimetres.

Since in each cubic millimetre there are 4,500,000 red cells, then the number of red cells in the 5 liters must be the product of these two quantities:

4,500,000 x 5,000,000 = 22,500,000,000,000 red blood cells.

Now, to find the distance they will cover aligned one after the other, knowing that their average diameter is 0.008 mm is:

22,500,000,000,000 x 0.008 mm= 180000000000 mm

$22.5\,\,10^{12} * 8\,\,10^{-3}=1.8\,\,10^{11}$ mm

In order to convert this distance into Km as requested, we use the fact that 1 mm = 0.000001 Km, or using exponents in base ten:

1 mm = $10^{-6}\,\,Km$

Then, the distance covered in kilometers is:

$1.8\,\,10^{11}\,*\,10^{-6} \,\,Km=1.8\,\,10^{5}\,\,Km=180000\,\,Km$

Part B)

The vaccine contains a total of $10^8$ bacteria per $cm^3$

In order to find how many bacteria we have in 80 $mm^3$ of the vaccine, we first need to convert 80 $mm^3$ into $cm^3$ :

$80\,\, mm^3 = 0.08 \,\,cm^3$

Then, if in one $cm^3$ there is $10^8$ bacteria, in $0.08\,\,cm^3$ there would be: $0.08\,*\,10^8$ bacteria. That is: $8\,\,10^6$ bacteria = 8000000 bacteria (eight million bacteria)
