AD = DB
Angle ADE = Angle CDB
Angle DAE = Angle DBC (Alternate angles)
Angle DEA = Angle DCB (Alternate angles)
Since you have two congruent angles and one congruent side, triangle ADE is congruent to triangle CDB. This means that DE is congruent to DC implying D is the midpoint of CE.
I think you divide 24 by 8 which = 3 and then times 3•3 which equals 9 so I think that 9 students out of 24 ride the bus
Answer:
4.8 hours
Step-by-step explanation:
First, divide the distance by time to get velocity.
S = D/T
S = 360/4
S = 90 mph
Then, subtract 15 from 90 to get the new speed.
90 - 15 = 75
Lastly divide the distance by the new speed to get time.
T = D/S
T = 360/75
T = 4.8
Therefore, it would take the car 4.8 hours to travel 360 miles at 75 miles per hour.
Answer:
160,000
Step-by-step explanation:
Estimations like this usually involve rounding to easy numbers to multiply. You could do this in a number of ways depending on your ability to keep track of factors in your head, but the easiest way (and what I assume your teacher is looking for) is to round to the nearest, largest-power-of-ten, which in this case is the hundreds. 786 is closest to 800, and 217 is closest to 200, and 200*800 is 160,000. No calculator required is the key. You can also be slightly more sure that this is <em>reasonable</em> because you rounded up for one and down for the other, approximately by the same amount, too.
