Answer:

\frac{470}{32-n}  

Step-by-step explanation:  

We have been given that there were 32 volunteers to donate blood. Unfortunately, n of the volunteers did not meet the health requirements, so they couldn't donate.            

So the number of volunteers that donated blood will be 32-n.

We are also told that the rest of the volunteers donated 470 milliliters each.

To find the units of blood donated by each of the volunteers we will divide total units of donated blood by number of volunteers, who donated the blood (32-n).

\text{Millimeters of blood donated by each volunteer}=\frac{470}{32-n}  

Therefore, each of the volunteers donated \frac{470}{32-n} millimeters of blood.

Find the distance between the point of bank and the point of office.

\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2}}
\sqrt{(-4 - (-6)^2 + (4 - (-3)^2}
\sqrt{(2)^2 + (7)^2}
\sqrt{4 + 49}
\sqrt{53}


The distance she travels is approximately 7.3 km.

Hope this helps :)

Explain the difference between |-3| and -3?
Ivan
They are opposites. since |-3| has the lines around it, this represents absolute value, which is not positive or negative but how far away the value is from 0. the plain -3 remains the same. |-3| is 3, because it is 3 units away from 0 on the number line.

1.3n-0.03=-9 (solve for n) grade lvl. 7
bazaltina [42]

Hello from MrBillDoesMath!

Answer:

-6.9


Discussion:  

1.3n - 0.03 = -9     =>              multiply both sides by 100

130n - 3 = -900 =>

130n = -900 +3 =  -897 =>     add 3 to both sides

n = -897/130  =>

n =  - (69 * 13)/ (10*13) =>

n = - 69/10 = - 6.9




Thank you,

MrB
