First , convert the mixed number (the fraction we are dividing by in the given maths problem) into an improper fraction .
Multiply the whole part (1) times the denominator (4) and add the numerator . The result is the numerator of our fraction , and the denominator stays the same .
So now our maths problem looks as follows :
Now turn the fraction you are dividing by over :
Now multiply the numerator of the first fraction times the numerator of the second fraction :
4
Perform the same operation with the denominators :
-4/14
So the result is :
Since the above fraction is not in it's simplest form , we divide the top and bottom by 2 (a common factor of both 4 and 14) :
Answer:
4/3
Step-by-step explanation:
Moving from (-4, -9) to (5, 3), x (the 'run') increases by 9 from -4 to 5, and y (the 'rise') increases by 12 from -9 to +3. Thus, the slope of the line connecting the two points is
m = rise / run = 12/9 = 4/3
It may help to think of the change in x (9) as the horizontal leg of a right triangle and the change in y (12) as the vertical leg. Then
m = (vertical leg length) / (horizontal leg length) = 12/9 = 4/3
I don’t understand please put it in a form i could possibly understand
perimeter should be 43 and the area should be 72m^2
this is squared btw
15% decrease means the bill would be 85% of the original bill ( 100% -15% = 85%)
multiply the current bill by 85%
2100 x 0.85 = 1.785
the bill would be $1,785
