Answer:
74.25feet
Step-by-step explanation:
Given the scale of a model train expressed as;
1in = 13.5feet
We are to express length of 5.5in in feet
5.5in = x
Divide both expressions
1/5.5 = 13.5/x
Cross multiply
1×x = 5.5× 13.5
x = 74.25feet
Hence the actual length of the car in feet is 74.25feet
This number can not be simplified or be a whole number it is already simplfyied.
Answer:
The mean would increase from 76 to 79
Step-by-step explanation:
50 +74+ 76+ 77 +78 +79 +80 +81 +82+ 84 = 761
761 ÷ 10 = 76
74+ 76+ 77 +78 +79 +80 +81 +82+ 84 = 711
711 ÷ 9 = 79
