The simplified fraction of .3 is 3/10
General formula for area of triangle is 
.
Where:
is height of triangle perpendicular to base side of triangle.
is the length of base side of triangle.
Multiplying and results in rectangle, dividing that by 2 gives you area of a triangle.
Hope this helps.
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:
They can buy 24 helmets.
Step-by-step explanation:
1 helmet = $15
$369 divided by $15 --> 24.6 --> 24 helmets
The correct answer is x= -9. Hope this helps!!
