One 5th of a kilogram is 200. <span />
Let x = first plane's speed.
We have the equation:
2 hours * x km/h + 1.5 hours * (x+60) km/h = 3135 km.
3.5 hours*x km/h + 90 km = 3135km
3.5hours*x km/h = 3045km
x = 870 km/h.
The first plane is traveling at 870 km/h, therefore since it is 60 km/h faster, the second plane is traveling at 930 km/h.

Answer:
Median: 17
Q1: 10
Q3: 23
Step-by-step explanation:
2, 4, 9, 11, 12, 16, 18, 20, 22, 24, 28, 32
Median is middle number/average of the 2 middle numbers. 16 + 18 = 34/2 = 17
First/lower quartile/Q1 = middle of lower half of ordered data set
= 9 + 11 = 20/2 = 10
Third/upper quartile/Q3 = middle of upper half of ordered data set
= 22 + 24 = 46/2 = 23
Sorry if this is too late. Posting it will probably save someone else, though.
Answer:
which agrees with the first choice (A) in your list of possible answers
Step-by-step explanation:
Notice that the area of the outer square is given by the square of it side 
.Then the outer area is given by: 
Now, the inner square's area we calculate by subtracting from the outer area four equal right angle triangles (those shaded in grey in the figure provided). Each of such right angle triangles have an area given by the general formula of a triangle's area:
Therefore the internal square's area is:
And then the quotient of this are over the larger square area becomes:
