Answer:
C) A =
Step-by-step explanation:
First, read through what the question is asking.
Now, read it again, but slowly and take in everything it is saying (Don't read into it too slowly, or else you will over-complicate the problem and get frustrated - told from experience :) )
Alright, 4 less than 3 times the width. So, lets rearrange this and give width a variable (w).
So, the length is equal to:
l = 3w - 4
and the width is equal to:
w = w
The area of a rectangle is A = l * w
Let's plug in the values.
A = (3w - 4) * w
Now, simplify:
A =
A = is your final answer.
I hope this helps!
The probability would be 9/12 and simplifies it you would divide both numbers by 4 and you get 3/4 as your answer
I think it’s just rational numbers
Answer:
1130.4 mm
Step-by-step explanation:
Given,
Radius ( r ) = 180 mm
To find : Circumference of the pulley ( C ) = ?
Formula : -
C = 2πr
Note : -
Value of π is 3.14
C = 2 x 3.14 x 180
C = 1130.4 mm
