Density = mass/volume
Let mass=x
8.94= x/(10*45*.2)
X=8.94*90
Mass=804.6 g
Hope this helped :)
Answer:
Step-by-step explanation:
I honestly have no idea what you mean by answer by formula, but I'm going to give it my best. I began by squaring both sides to get:
(a² - b²) tan²θ = b² and then distributed to get:
a² tan²θ - b² tan²θ = b² and then got the b terms on the side to get:
a² tan²θ = b² + b² tan²θ and then changed the tans to sin/cos to get:
and isolated the sin-squared on the left to get:
and distributed to get:
***
*** and factored the right side to get:
and utilized a trig Pythagorean identity to get:
and then solved for sinθ in the following way:
so
This, along with the *** expression above will be important. I'm picking up at the *** to solve for cosθ:
and get the cos²θ alone on the right by subtracting to get:
and divide by b² to get:
and factor on the left to get:
and take the square root of both sides to get:
and simplify to get:
and go back to the identity we found for sinθ and sub it in to get:
and simplifying a bit gives us:

That's my spin on things....not sure if it's what you were looking for. If not.....YIKES
1/3 ounce - 1/4 pound is 4 ounces and then you just divide by 12, resulting in .3333333333 or in other words, 1/3
Answer:
$58.50
Step-by-step explanation:
The fee will be equal to the percentage times the selling price. Converting the percentage to a decimal, we get 18%=0.18
Multiplying this by the selling price:
325*0.18=58.5
