Original Ratio of 1 in = 7 ft so 3 in = 21 ft
Now, New ratio 1 in = x ft so 3 in = 27ft
1/x = 3/27
cross multiply a/b = c/d ad = bc
1/x = 3/27
3x = 27
x = 9
1 in represents 9 ft
4 is the answer because there are only 4 numbers greater than 10.Those are the people who ride bikes ore than 10 times.
Answer:
x^2 -12x+20
Step-by-step explanation:
If the zeros of the functions are at 10 and 2
(x-10) (x-2)
FOIL
x^2 -2x-10x+20
Combine like terms
x^2 -12x+20
To get the correct answer to this question, you just need to divide 20% by 0.05% in order to get the answer, how many times a manual filer is more likely to make an error than an electronic file.
20: 0.05 = 400
The answer is C. 400 times more likely.
