It’s 12h-14 because -6 and -8 combine to be -14 and 5h and 7h equal 12h
By the pythagorean theorem, we know that (leg1)^2 + (leg2)^2 = hypotenuse^2. to see the proof refer to the following link: http://jwilson.coe.uga.edu/EMT668/EMT668.Student.Folders/HeadAngela/essay1/Pythagorean.html
plugging in what we know we have 16^2 + leg^2 = 20^2 and we find that leg = 12.
The question is to find an expression for the expenses
<u>Answer:</u>
E (x) =n + 5
<u>Explanation:</u>
The profit is defined as the difference between the revenue and the expenses.
<u>This means that:</u>
profit = revenue - expenses
<u>Now, we rearrange the equation to solve for expenses:</u>
expenses = revenue - profit
<u>From the given, we know that:</u>
expression for revenue is 18n
expression for profit is 17n - 5
<u>Substitute in the equation to get expression for expenses as follows:</u>
E (x) = 18n - (17n - 5)
E (x) = 18n - 17n + 5
E (x) = n + 5
Hope this helps :)
Answer:
12.5a-8.1b
Step-by-step explanation:
Remove the unnecessary parenthesis
14.2+9.8b-(13.1b-2a)-(3.7a+4.8b)
Collect like terms
12.5a+9.8b-13.1b-4.8b
Giving you the answer of: 12.5a-8.1b
Answer:
Diameter of a hemisphere: d = 2 * r ,
Volume of a hemisphere: V = 2/3 * π * r³ ,
Base surface area of a hemisphere: Ab = π * r² ,
Cap surface area of a hemisphere: Ac = 2 * π * r² ,
Total surface area of a hemisphere: A = 3 * π * r² ,
We know that for a hemisphere whose radius is 9 units, The volume is: Volume of hemisphere=2πr33 Volume of hemisphere = 2 π r 3 3
Step-by-step explanation:
