For this case we have that by definition the mass is given by:
Where,
- <em>D: density
</em>
- <em>V: Volume
</em>
The volume of a pyramid is given by:
Where,
- <em>A: area of the base
</em>
- <em>h: height
</em>
Substituting values we have:
We now calculate the mass:
Answer:
he needs 7.74 pounds of zinc
35 is the 20% so you multiply 35x5=175. 175 is the whole thing so you minus 175-35=140 which is the remaining money so half of that is 70
The equation is the following
This is a difference of two squares, the first one being the square of
, the second one being the square of
. The difference of two squares can be factorized as
If we apply this rule to our equation, we find
<span>(a) the slope of curve is calculated from the derivative of the curve expression y=5/x. In this problem, the slope m=-5/(a^2).
(b) x=1, y=5,and m=-5, the tangent line is y-5=-5*(x-1).
x=4, y=5/4, and m=-5/16, the tangent line is y-5/4=-5/16*(x-4)</span>
Answer:
482 feet tall
Step-by-step explanation:
<em>x = third building</em>
<em>x + 65 = first building</em>
<em>x + 34 = second building</em>
<em />
x + 65 + x + 34 + x = 1350 feet
3x + 99 = 1350
3x = 1,251
x = 417
first building = x + 65
(417) + 65 = 482 feet
first building = 482 feet
