Answer:
Step-by-step explanation:
42cm=420mm That's times 10
.837kg=837g That's times 1000
89milliliter=.089liters That's divided by 1000
.72meters=.00072 That's divided by 1000
267cm=.0027 kilometers divided by 100,000
Answer:
The second city is 54 miles behind the first city
Step-by-step explanation:
The first bus is assumed to go ahead of the second bus and is moving at 54 mph. The second bus is moving at a speed such as 54 mph is 60% (0.6) of its speed.
The speed of the second bus is then 54/0.6 = 90 mph
When 1 and a half hour has passed, the first bus has moved a distance of
= 81 miles
The second bus (behind the first bus) has moved
= 135 miles
The problem states they both meet in that time, it can only be possible if the second bus departed a distance 135 - 81 = 54 miles behind the first city
So, the second city is 54 miles behind the first city
Answer:
The answer is 1/9.
Step-by-step explanation:
When solving for the slope of a perpendicular line to a given, you have to flip the opposite reciprocal.
First take the number and flip the reciprocal, in this case -9 turns into -1/9.
Then flip the sign, like making a negative to a positive or a positive to a negative. In this case make -1/9 into 1/9
Therefore the answer is 1/9.
Answer:
θ = 50 degrees
Step-by-step explanation:
we have sin θ = cos 40°
θ = arcsin ( cos 40°)
and make sure θ is less than 90 and greater than 0
θ = arcsin (0.766044443)
θ = 50 degrees
this is your answer, i hope this helps you
