Answer:
45*10^10
Step-by-step explanation:
5*9*10^3*10^7=45*10^(3+7)=45*10^10
cause a ^m*a^n=a^(m+n)
Answer:
A
Step-by-step explanatiWe know x is between 1 and 3 so the best estimate is 2 even though the answer could also be 3 but that will be skewed.
Answer:
- B. (x, y) → (x - 6, y + 3)
Step-by-step explanation:
<u>Find the difference of corresponding coordinates</u>
<u>H to H'</u>
- x = - 3 - 3 = - 6
- y = 1 - (-2) = 3
<u>K to K'</u>
- x = 1 - 7 = - 6
- y = - 2 - (-5) = 3
<u>According to above, the rule is:</u>
Correct choice is B
Using the student id given above, a = 19 and b = 7
Average speed for the first 54 km = 48+a km/h
Plug a = 19
Average speed for the first 54 km = 48+19 = 67 km/h
Average speed for remaining 86 km = 43-b km/h where b = 7
Average speed = 36 km/h
Average speed of entire journey = total distance / total time taken
Time taken to cover 54 km = hr
Time take to cover 86 km = hr
Total time taken = 3.2 hours.
Total distance = 86+54= 140 km
Average speed of the entire trip = = 43.75 km/ h
