<span>Her travel time to her destination can be found by dividing 50km by 40km/h to get 1.25 hours or 1 hour 15 minutes. He travel time home can be found by dividing 50km by 60km/h to get 0.83 hours or. 50 minutes. The total time was 2.083 hours or 2 hours and 5 minutes. So here average speed is 100 divided by 2.083 hours = 48 miles per hour.</span>
<span>3pi is an irrational number; the other options are not.</span>
Answer:
The correct answer is:
A. 27,465 +52,534 = 79,899
Step-by-step explanation:
Given are the options for addition
We have to check each addition one by one
So,
A. 27,465 +52,534 = 79,899
This option is the example of error of addition by one. The answer should have been 79,999. Hence there is an error in addition ..
Hence, option a: 27,465 +52,534 = 79,899 is the correct answer ..
Answer:
72 degrees
Step-by-step explanation:
To determine the value of DBC, we first have to determine the value of q
Angle on a straight line = 180 degrees
7q - 46 + 3q + 6 = 180
10q - 40 = 180
collect like terms
10q = 180 + 40
10q = 220
q = 22
Substitute for q in angle dbc
3(22) + 6 = 72 degrees
