Part B: Write an inequality to represent the amount of money charged per lawn, the cost of the lawnmower and the profit.
Answer:
I got 65
Step-by-step explanation:
The profit will be given as:
P=$15x−$225
(where we subtracted the cost of the mower) so that P=$750
x will be the required number of needed lawns.
We need to solve:
$750=$15x−$225
rearranging:
x=$750+$225 / $15 =65 lawns
Which expression can be used to determine the greatest possible volume of the cardboard box?
A) (x−7)(x−11)x
B) (7−2x)(11−2x)x
C) (11−7x)(11x−7)
D) (7x−11)(7−11x)
Answer:
Option B
Step-by-step explanation:
Given is a rectangle with width 7 and length 11.
From each corner of the rectangle a square of length x is cut and foled to make a box
Now for the open box we made, height = x
width = rectangle width - 2 times d
= 11-2x
Length = rectangle length-2x
Hence volume of box
=lwh
= (7-2x)(11-2x)x
Answer: B)
Step-by-step explanation:
Given: The length of the cardboard = 11 in.
The width of the cardboard =7 in.
If a box is created without a top from a piece of cardboard, but cutting out square corners with side length x, then the dimensions of box will be:-
Width (w)=
length (l)=
Height (h)=
Now, volume of rectangular box is given by :-
Hence, the expression can be used to determine the greatest possible volume of the cardboard box is given by :-
It can be curved.
It looks like a straight line.
It must cross the origin.
Answer:
All you had to know to get this right is that a Linear Function is a straight line and a Nonlinear Function has a curve to it :)
