Answer:
A.
Step-by-step explanation:
As shown in the question we can interpret the following:
Now all we have to do is plug these values into the equation, and so we find that A. is the correct answer.
There were 60 girls because you do cross multiplication (5 x 48 is 240 4 x 60 is 240)
Ok so what you need to know about an octahedron is it's basically two square pyramids stacked on top of each other (one is upside down of course).
The formula for volume of a pyramid is Bh/3.
Base= 8*8=64
Height= 3 each
64*3/3= 64 mm^3 per pyramid.
64*2=128 mm^3 for the octahedron
Final answer: 128 mm^3
We need to find common denominators before we try to add. Let's try 72.
5/9→40/72 3/8→27/72
Let's add them together.
40/72+27/72=67/72; since 67 is prime, the fraction can't be simplified.
5/9 plus 3/8 equals 67/72
