Answer:
B
Step-by-step explanation:
Mr. Jackson invested $800 at 6% per year and $ 2400 at 4 % per year
<h3><u>Solution:</u></h3>
Mr. Jackson invested a sum of money at 6% per year, and 3 times as much at 4% per year.
Let the sum invested be ‘a’ and ‘3a’ at 6% per year and 4 % per year respectively
Also, his annual return totaled $144
We can form following equation on the basis of question:-
a = $800
The amount of money invested at 6% = a = 800
The amount of money invested at 4 % = 3a = 3(800) = 2400
So, the amount of money invested at 6% is $800 and the amount of money invested at 4% is $ 2400

Answer:
9m
Step-by-step explanation:
The surface area of a cube is given by
SA = 6s^2 where s is the side length
We know the surface area is 486 and the side length is z
486 = 6z^2
Divide each side by 6
486/6 = 6z^2/6
81 = z^2
Take the square root of each side
sqrt(81) = sqrt(z^2)
9 = z
Each side has a length of 9m
