We know that there is a total of 900 cells, and 37 of the samples 60 are red. 900/60 is our unit rate of 15. 37 times 15 is 555. We will see 555 red blood cells in all of the cells.
555 is our answer.
Please forgive any typeos because I did this on my phone.
Step-by-step explanation:
You can first multiply the width by two. Then you subtract that from you perimeter to figure out your length. Whatever number you get divide it by two and there's your length.
Example:
Perimeter =30 Width=5
5 times 2= 10
30-10=20
20/2=10
So your length equals 10.
I hope this helps!
You know you have to draw the triangles right?
Hello there! Using the rules of addition, we can identify that when adding a positive to a negative number, the result shifts toward the positive side but takes the sign of the greater number. It will be demonstrated in this problem to simplify how problems like this are solved:
Step 1: Rewrite the problem
-14 + 7 = ?
Step 2: Since we’re adding 7 to a negative number, that means the negative number decreases by the quantity it’s being added by.
This means we would have to really subtract 7 from 14 to get 7.
Step 3: Keep the sign of the greater number
Since 14 is greater than 7, we will keep the negative sign in accordance.
Step 4: Simplify
-14 + 7 = -7
Using the rules of addition, we will find that -14 + 7 = -7. If you need additional help, let me know and I will gladly assist you.
