Answer 1

Answer: so F(m) because F dollars for every mph over the speed limit
so 40 dollar speeding fine so +40
10 dollars for every mile over and m=miles over so put them all toghether and get
F(m)=10m+40

1.
so if you were going 78 mph
to find the mph over you would do 78-70=8mph over so put in 8 for m and get
F(8)=10(8)+40=80+40=$120 fine for going at 78 mph

What is 17/100 into a decimal

Answers

The answer is 0.17. To convert fraction to a decimal, you must divide a numerator by a denominator. In 17/100, 17 is the numerator and 100 is the denominator, thus 17/100 = 17 : 100. When you divide by 100, put the decimal spot two spaces from the right-hand side because 100 has two zeros. Therefore: 17/100 = 17 : 100 = 0.1Hope this helps. Let me know if you need additional help!

Answer: 0.17
