Answer:
x = 40
Step-by-step explanation:
2/5x + 1/4x = 26
~Find common denominators
8/20x + 5/20x = 26
~Combine like terms
13/20x = 26
~Multiply 20/13 to both sides
x = 40
Best of Luck!
Answer:
A to B = 2000 m/s
C to D = 30,000m/s
Step-by-step explanation:
A to B is 10secs and the distance is 200m so you multiply them and you get 2000m/s
C to D is 60secs and the distance is 500m so you multiply and you get 30,000m/s
Answer:
The correct option is A. The height of tree is 60 ft.
Step-by-step explanation:
From the given figure it is noticed that the building is creating a right angle triangle from a point and the tree divides the hypotenuse and base in two equal part.
According to midpoint theorem of triangle: In a triangle, if a line segment connecting the midpoints of two sides, then the line is parallel to third side. The length of line segment is half of the length of third side.
Using midpoint theorem of triangle, we can say that the length of tree is half of the building.



Therefore correct option is A. The height of tree is 60 ft.
Make into improper fraction
5 and 1/6=5+1/6=30/6+1/6=31/6
3 and 2/4=3+2/4=3+1/2=6/2+1/2=7/2
5 and 1/6 times 2 and 2/4=
31/6 times 7/2=
217/12=
216/12+1/12=
18+1/12=
18 and 1/12
