this can be solved using
the fomula of the volume of a right circular cylinder
V = pi*r^2*h
Where pi = 3.1416
R is the radius
H is the height
V = 3.1416(1.68^2) (5)
V = 44.3342 ft^3 (7.5
gallon / 1 ft^3)
<span>V = 332.5062 gallons</span>
The equation is:
13.25h = 278.25
Solve for h in this case by dividing 278.25 by the 13.25 dollars per hour.
The answer will be:
21 hours
This kind of exercise can be real drudgery. But it's almost all simple arithmetic, so better you than me. I'll do one of these for you, which will show you how to do the other one.
a). sin · cot / sec
You're supposed to know that [ cotangent = cosine/sine ]
and [ secant = 1/cosine ].
Then the problem becomes
sin · (cos/sin) / (1/cos) = cos²
Aw shucks, I might as well also set up 'b)' for you:
b). cos · csc / tan
You're supposed to know that [ cosecant = 1/sine ]
and [ tangent = sine/cosine ].
Then the problem becomes
cos · (1/sin) / (sin/cos) = (cos/sin)²
Now simply plug in the given values of cos A and sin A .
And may I compliment you on your nail care !
Answer:
3x+2
Step-by-step explanation:
x+3+2x−1
=x+3+2x+−1
Combine Like Terms:
=x+3+2x+−1
=(x+2x)+(3+−1)
=3x+2
