Answer:
So dimension of rectangle are :
Length = 32
Width = 40
Step-by-step explanation:
Let the length of rectangle be 4x and width of rectangle be 5x.
Remember ratio of length and width is 4 to 5.
Perimeter of rectangle is given as 144.
i.e 2 (length +width) = 144
or 2 ( 4x + 5x ) = 144
Solving this for x, we get :
or 9x = 144/2
or 9x = 72
or x = 72/9
or x = 8
So dimension of rectangle are :
Length = 4 x = 4*8 = 32
Width = 5x = 5*8 = 40
The consult must make at least 600 dollars. That means the combination of reviews and new written pieces must be at least $600, or greater than or equal to (<span>≥) $600.
You are also told that each new piece = $120 and each review = $60. Let's use variables n = new piece and r = review. (You might be given different variables for your answer choices). That means the total money made from a combination of new pieces and reviews is:
120n (money made from each new piece times n number of new pieces) + 60r (money made from each review times r number of reviews).
Put that all together to get your inequality:
120n + 60r </span>≥ 600
-----
Answer: 120n + 60r ≥ 600
Surface of the cylinder : 2*(pi*radius^2)+(2*pi*radius*height)=2(pi*1.5^2)+(2*pi*1.5*9)=31.5pi cm^2 ~99 cm^2
Volume : pi*radius^2*height=pi*1.5^2*9=20.25pi~64 cm^3
