Answer:
The maximum profit will be reached by buying 500 brass magnetic spheres and 1500 silver magnetic spheres.
Step-by-step explanation:
In order to solve this you need to create a system of equations, with two values that will create the answer we are looking for, the thing that we don't know here is how many of each are we buying so the number of silver magnetic spheres will be represented by "y" and the brass magnetic spheres will be represented by "x".
So we know that x+y=2000
That's our first equation, our second would be the expense, which would be
8x+16y=20,000
We now just solve for one of them
x=(2000-y)
8(2000-y)+16y=20,000
16,000-8y+16y=20,000
8y=4,000
y=500
So we know that the maximum profit will be reached by buying 500 brass magnetic spheres and 1500 silver magnetic spheres.
Answer:
Step-by-step explanation:
t/6 is the same as (1/6)t
-5 - 1/6t ≥ -9......add 5 to both sides
-1/6t ≥ -9 + 5
-1/6t ≥ - 4....u can either divide both sides by -1/6, or u can multiply both sides by -6....either way, u have to switch the sign because when dividing/multiplying by a negative requires that. I am multiplying both sides by -6, cancelling the -1/6 on the left
t ≤ -4 * -6
t ≤ 24 <=======
Answer:
0.45
Step-by-step explanation:
percent means out of a hundred, hence
45% = 
= 0.45
Answer:
Since length and width are perpendicular, Doubling either one will double the area. So Doubling both will quadruple the area. 2x2 = 4.
This idea works if the dimensions doubled are those that are used to compute area. Like the base and height of a triangle.
More generally, in a polygon, if all the sides are doubled, the area is multiplied by 4. In a circle, Doubling the radius will quadruple the area.
In 3 dimensions, Doubling one dimension will double the VOLUME. Doubling two perpendicular dimensions will quadruple the volume and Doubling 3 perpendicular dimensions will multiply the volume by 2x2x2 or 8.
