Answer:
therefore x = 600 mph
therefore the speed of the other plane y = x - 110 = 600 - 110 = 490 mph
Step-by-step explanation:
i) Two planes are 2725 miles apart and are travelling towards each other.
ii) One plane is travelling 110 mph faster than the other plane.
iii) the planes pass each other in 2.5 hours
iv) let the speed of one plane be x mph
v) let the speed of another plane be y mph
vi) therefore x - y = 110 mph
vii) and also x + y = 2725/2.5 = 1090
viii) adding the equation in vi) to the equation in vii) we get 2x = 1200
therefore x = 600 mph
ix) therefore the speed of the other plane y = x - 110 = 600 - 110 = 490 mph
The negative 4 in the parenthesis caused the graph to move four units to the right.
Median means middle. How you solve this is by first putting the numbers in order from least to greatest:
36 41 43 45 46 48 48 51 51 52
Now that it is in order in each "level" take away the smallest and largest number until you get to the middle
36 41 43 45 46 48 48 51 51 52
41 43 45 46 48 48 51 51
43 45 46 48 48 51
45 46 48 48
46 48
Now this is a bit tricky because there isn't one number to signify the exact middle. When you have two numbers left you must take the mean of those two numbers. This means that you add the two numbers left and then divide the answer by 2:
46 + 48 = 94
94 ÷ 2 = 47
Hope this helped!
All you have to do is just bring the numbers that are not zero from each digit.
so in this process, the answer you would get is 724,562.
I hope this helped
