Is that 258.177 or 258,177. because if its a decimal then you would look at the third space behind the decimal since that is hundredth thousandths and since its 7 it would round the other 7 to be an 8 so they answer would be 258.18
Answer:
CBA = DEF
Step-by-step explanation:
DEF is the answer because CBA is the exact same triangle as the other one, it just upsidedown.
Answer:
257.5 mph
332.5 mph
Step-by-step explanation:
The initial distance between the two planes is 960 miles, while the final distance (after t=1.5 h) is 75 miles, so the total distance covered by the two planes in 1.5h is
miles
Calling v1 and v2 the velocities of the two planes, we have the following equations:
(1) 
--> velocity of plane 1 exceeds velocity of plane 2 by 75 mph
(2) 
--> the total distance covered by the two planes is 885 miles (t=1.5 h is the time, and the products v1 t and v2 t represent the distance covered by each plane)
Substituting t=1.5 h, the second equation becomes:
By substituting (1) into this last equation, we find:
And substituting this back into eq.(1), we find
So, the speeds of the two planes are
257.5 mph
332.5 mph
Answer:
211.1
Step-by-step explanation:
3 isn't greater than or equal to 5 so it will not round up to 2 so your answer will be 211.1
