Answer:
Step-by-step explanation:
Let t represent the time it took Emanuel to drive home from college. If the total round trip took 11 hours, it means that the time it took
Emanuel to drive from home back to college would be (11 - t) hours.
Emanuel drove home from college traveling an average speed of 70 mph.
Distance = speed × time
Distance covered by driving from college to home is
70 × t = 70t
He drove back to the college the following week at an average speed of 62.7 mph.
Distance covered by driving back to college from home is
62.7(11 - t) = 689.7 - 62.7t
Since the distance travelled is the same, then
689.7 - 62.7t = 70t
70t + 62.7 = 689.7
132.7t = 689.7
t = 689.7/132.7
t = 5.19 hours.
Therefore, the time that it took Emanuel to drive from home back to college is
11 - 5.19 = 5.81 hours
For this case we have the following expression:
What we must do in this case is to use one of the properties of the sum.
In this case, we must use the associative property.
The associative property states:
We have then:
Simplifying we have:
Answer:
the following is equal to (2x / 3 - 7) + 7
D. 2x / 3.
Answer: the following points are in Quadrant 3
Answer:
140 degree or Answer D
Step-by-step explanation:
140 degrees is the answer for a Nonagon
Answer: 542
Step-by-step explanation:
The quotient is known as the final answer gotten after the value of 4878 has been divided using 9. The answer as such will be 542 (i.e 4878/9)
9 goes in 48 five times, 5 is written and remainder of 3 is kept above 7 to make it 37; then 9 goes in 37 four times, 4 is written and the reminder of 1 is written above 8 to make it 18; and finally 9 goes in 18 two times without remainder, then we write 2. Combining the answers gives our Final answer 542.
