Answer:
109 yd^2
Step-by-step explanation:
formulas used are
3(1/2 b.h) + 25
(original - new)/original = discount
65-42.25)/65 = discount
22.75/65= discount
.35 = discount
multiply by 100 to put in percent form
35 percent
An odd function is a function of a form 
where n is an odd number.
Some examples would be functions:
.
A formal definition of odd function is the following.
(Algebraic proof).
Let 
(real function).
The function is odd if the below equation is true for all x and -x for which the function is defined:
.
Hope this helps.
Answer:
6
Step-by-step explanation:
x/18 = 1/3
3x = 18
x = 6
To solve this problem, let us say that the action of
totally painting a small house is called “1 job”. Therefore the rates of each
person in painting the small house are:
Bill = 1 job / 3 days = 1 / 3
Sharon = 1 job / 4 days = 1 / 4
Wilber = 1 job / 5 days = 1 / 5
Therefore the total rate is calculated by simply adding
the rates of the three.
(1 / 3) + (1 / 4)
+ (1 / 5) = 1 / x
where x is the number of hours it take if all them paint
together
Calculating for by multiplying both sides by 60:
60 [(1 / 3) + (1 /
4) + (1 / 5) = 1 / x]
(60/3) + (60/4) + (60/5) = 60 / x
20 + 15 + 12 = 60 / x
47 = 60 / x
x = 60 / 47 hours
Answer:
60/47 hours
