Answer:
Simplified: -4u? + 5u^2 - 5u - 3
Step-by-step explanation:
Answer:
Using formula to calculate the circumference of wheel:
where
D is the distance bike travel
n is the number of times rotation
C is the circumference of the wheel
As per the statement:
Lin’s bike travels 100 meters when her wheels rotate 55 times.
here, n = 55 rotation and D = 100 meter.
then by definition:
meter
Therefore, the circumference of her wheel is, 1 9/11
Step-by-step explanation:
Two trips a day for 5 days = 10 trips
(3/10)(10)= 3 miles
The answer is 16 degrees to your problem.
Writing the equation that governs this situation:
-3C - (2.5C/hr)x = -18C
Simplifying, -3 - 2.5x = -18, or 3 + 2.5x = 18
Combining like terms: 2.5x = 18-3 = 15
Then x = 15/2.5 = 6. The temp. will reach -18C after 6 hours.
