5 Erasers, 4:1 is equal to 20:5, if you just multiply both numbers by 5
Answer:
1)( y= 0.12 * x ) y(dependent) , x(independent) 2) x=150 : y=18 / x=300 : y=36 / x=450 : y=54 / x=600 : y=72 / x=750 : y=90 / x=900 : y=108 3) 300+750+1050=2100 pound
2100*0.12=252 pound food they need to eat in each day
252*7=1764 pound in each month
Perimeter = the addition of all of the side lengths of the polygon.
The side lengths are 9cm, 6cm, 10cm, 5cm, 4cm, and 4cm.
So the perimeter is the following...
Perimeter = 9 + 6 + 10 + 5 + 4 + 4 = 38cm total
Well .03 is equal to 3/100 so it is already in simplest form
Data:
Model: 41cm
Scale: 1cm/24feet
To convert the measure of the model to the real Tower you use the scale factor
The scale factor is 24ft/cm
To know the height of the Eiffel Tower you multiply the height in the model for the scale factor:

Then so, the height of the Eiffel Tower is 984ft
