Answer:
C. 67 mph
Step-by-step explanation:
The speedometer reports speed based on the number of revolutions the tire makes in a given time period. If the motorcycle travels 28/25 times as far on each revolution, its speed is 28/25 times as great.
(28/25)(60 mph) = 67.2 mph ≈ 67 mph
_____
The distance traveled is proportional to the circumference of the tire, which is proportional to the diameter. Hence, actual speed for a given speedometer reading is proportional to the diameter of the tire.
Answer:
The range of the oven is 
Step-by-step explanation:
Consider the provided information.
The internal temperature falls to 20 degrees below the set temperature and turns off when the temperature reaches 5 degrees above the set temperature.
You preheat the oven to 405 degrees before putting a cake in and baking it for an hour at 405.
The internal temperature falls to 20 degrees, therefore the lowest set can be:
405-20=385 degree.
The temperature reaches 5 degrees above the set temperature 405, therefore the upper set is: 405+5=410 degree.
Hence, the temperature will be lying between 385 degree and 410 degree.
This can be written as: 
Hence, the range of the oven is 
Answer:
4x-2
Step-by-step explanation:
<u>First, distribute the minus sign.</u>
-2x+3-(5-6x)
-2x+3+ -1(5)+ -1(-6x)
-2x+3+ <em>(-5) </em>+ <em>(6x)</em>
-2x+3-5+6x
<u>Next, combine like terms.</u>
<em>-2x</em>+3-5<em>+6x</em>
(-2x+6x)+(3-5)
4x+(-2)
4x-2
