Answer:
<h2>-3n = 27</h2>
Step-by-step explanation:
The product of a number and negative three is twenty-seven.
<em>n - </em><em>a number</em>
the product of a number and negative three: <em>n · (-3) = -3n</em>
Let x represent the amount of lawn mowers that were manufactured
The company has to pay $34,816 before they even make any lawn mowers plus $388 per lawn mower.
((34816+388x)/x)=660
34816+388x=660x
34816=272x
X=128
Therefore, there were 128 lawn mowers manufactured
Answer:
V ≈ 1847.26
Step-by-step explanation:
<u>Circular Cone Formulas in terms of radius r and height h:</u>
The volume of a cone:
V = (1/3)πr2h
Slant height of a cone:
s = √(r2 + h2)
Lateral surface area of a cone:
L = πrs = πr√(r2 + h2)
The base surface area of a cone (a circle):
B = πr2
The total surface area of a cone:
A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
Therefore, the solution
V = πr 2h
/ 3 = π·142·9/ 3 ≈ 1847.25648
