4 hours and 15 minutes =4+15/60=4.25 hours
the average speed of the train = 250/4.25=58.82mph
Correct answer:
15
Explanation:
This problem can be solved by applying the area formula:
Since this question provides the area of the kite and length of one diagonal, plug that information into the equation to solve for the missing diagonal.
Thus the solution is:
60=8×diagonalB2
60×2=8×diagonalB
120=8(diagonalB)
diagonalB=1208=15
Answer:
So the value of u is 
degree.
Step-by-step explanation:
Given;
Three angle 
, 
degree and 
degree in a Triangle.
We know;
Addition of three angle in a triangle is equal 
degree
∴ The value of u is [tex]24[\tex] degree.
Slope forumla is:
(y2-y1)\(x2-x1)
so, (1-8)\(12-3) or -7\9. I see that 7/9 is in your answer list twice, so whichever is negative is your answer
