<span>4. Unit rate implies how much in one hour. If 306 miles is in 10 hours, in one hour, it will be just one-tenth of 306 miles. So divide 306 by 10. To divide by 10, just place a point before one digit from the right. So the answer will be 30.6 milers/hour.
5. Unit rate here implies how much in one month. If 33.6 gallons is in 6 months, in one month, it will be just one-sixth of 33.6 gallons. So divide 33.6 by 6. The answer will be 5.6 gallons/month.</span>
5 - -10 = 15.
The difference between the actual temperature and the wind chill is 15.
Answer: D
take 5/15 and simplify to 3/1
The simplified expression would be 4y^6 / x^5. However, I had a hard time distinguishing which numbers were exponents or not in your question.
Consider triangle XYZ with vertices at points X(1,-3), Y(3,0) and Z(-1,-1). If triangle XYZ is reflected across the line y = 1, then the rule of reflection is
(x,y)→(x,-y+2).
The image X' of point X will have coordinates according to the given rule:
X(1,-3)→X'(1, -(-3)+2)=X'(1,5).
Answer: correct choice is D.
