X - invested for the money at 11%
70 000 - x - deposited at 12%
0.11x + 0.12(70000-x)=7900
0.11x + 8400 - 0.12x = 7900
8400- 7900 = 0.01x
500 = 0.01x
x=50 000 invested at 11%

hello ....
the equation of a plane that is ; ax+by+cz +d =0
the vector perpendicular to this plane is : V(a,b,c)
in this exercice ; a = -4 b= -4 c = -1
then: the equation of a plane that is ; -4x-4y-z +d =0
but the plane passing through the point (−2,−5,5) :
-4(-2)-4(-5)-(5) +d =0
23+d =0
d =-23
the equation of a plane is : -4x-4y-z-23 =0

Answer: Not too sure. Sorry.
Step-by-step explanation:
Answer:
1.5 mL
Step-by-step explanation:
The abbreviation mcg stands for "microgram," or 10^-6 grams. The abbreviation mg stands for "milligram," or 10^-3 grams. The relationship between these is ...
1 mg = 1000 mcg
<h3>Dose</h3>
The order for 6000 mcg is an order for 6(1000 mcg) = 6(1 mg) = 6 mg. At 4 mg/mL, the quantity of dexamethasone required is ...
(6 mg)/(4 mg/mL) = (6/4) mL = 1.5 mL
The nurse will give 1.5 milliliters of dexamethasone.
