Answer:
<h3>246.6 meters per hour</h3>
Step-by-step explanation:
Step one:
Speed uphill 100meters per hour
Speed on flat ground 120 meters per hour
Speed uphill 150 meters per hour.
Required
The average speed.
Step two:
To get the average speed, let us add all the individual speeds and divide by 3(three different speeds), then multiply the result by 2(the return trip)
Average speed= (100+120+150)*2/3
Average speed= 740/3
Average speed= 246.6 meters per hour
D. because he says a little least and plus two of the other answer choices are negative so use process of elimination and D will be your answer.
The unit of density [kgm^-3] displays the formula.
So density=mass/volume.
Convert 2160g into kilograms [2160/1000=2.160kg]
Convert volume of 240cm^3 into m^3
100cm=1m
100x100x100=1000000cm^3=1m^3
240/1000000=[2.4x10^-4]
Final calculation
2.160/2.4x10^-4=9000
Answer: 9000kgm^-3
The answer is 12. This is because 4+8=12, and 12 divided by 2 is 6. Therefore a=6. 10+8=18, and 18/3 equals 6. Therefore, b=6. 6+6 is 12.
<u>Answer:</u>
∠MKL
<u>Step-by-step explanation:</u>
Two angles are said to be adjacent angles if they share a common vertex and a common side but they do not overlap.
The triangle given here is ΔMKL with a line extended outside from K to J.
The two angles ∠MKL and ∠MKJ are adjacent angles as they share a common vertex K and a common side which is MK. The angle ∠MKL comes in the closed triangle while ∠MKJ is formed by extending the point K.
Therefore, ∠MKL is an interior adjacent angle while ∠MKJ is the exterior adjacent angle here.
