Answer:
849.24 cm²
Step-by-step explanation:
we know it is a cube so to find the surface area of each square you do
12x12=144 and there are 5 sides so 144x5=720
We know sides of the squares are 12 cm so half of that (6) would be the bottom of the triangle
Now using pythagorus you would do a²+b²=c²
15²+6²=c²
225+36=c²
√261=√c²
16.15=c this only half of one of the sides of the pyramid so you would times 16.15 by 8 to equal 129.24
now add 720+129.24=849.24 cm²
Answer:
35%
Step-by-step explanation:
To figure out the percentage of bronze medals, we must figure out the percentages of the gold and silver medals first.
We already know that 45% of the medals were silver.
We know that 4 of the 20 medals were gold.
4/20 as a percentage would be 20/100, or 20%.
So, 20% of the medals were gold, and 45% of them were silver.
45% + 20% = 65%
100% - 65% = 35%
So, 35% of the medals awarded were bronze.

Answer:
The break-even points are: x = 500, and x = 70
Step-by-step explanation:
The break even points are those x-values for which the Revenue equals the Cost, so there is no money lost.
Since the formulas for both Revenue and Cost are given, we find the breaking points by setting the functions equal to each other:

where we have gathered all terms on one side of the equation and written the equation in standard form.
We can use the quadratic formula to solve for "x":
has solutions given by: 
In our case, 
So the solutions are:

This leads to two solutions:

These are the break-even points.
Answer:
The area of the rectangle can be found using two different expressions: a(b + c) or ab + ac. The equality of these expressions, a(b + c) = ab + ac, is the distributive property.
