Answer:
FH = 38
Step-by-step explanation:
Here, given the point of intersection of the two diagonals at E, we want to calculate the length of FH
The point of intersection of the diagonals is the midpoint of each as the diagonals bisect each other
thus,
3x + 4 = 5x - 6
5x-3x = 6+ 4
2x = 10
x= 10/2
x = 5
but Eg is 5x-6
and FH = 2EG
FH = 2(5x-6)
FH = 10x - 12
Substitute x = 5
FH = 10(5) -12
FH = 50-12
FH = 38

Answer:
1.5 km/hour
Step-by-step explanation:
d is the David's speed in still water
c is the speed of the current
Going with the current, he travels d+c km per hour.
Going against the current, he travels d-c km per hour.
d+c = (20 km)/(2.5 hours) = 8 km/hour
d-c = (20 km)/(4 hours) = 5 km/hour
Add the equations to eliminate the c terms
d+c = 8
d-c = 5
----------
2d = 13
d = 6.5 km/hour
c = 8-d = 1.5 km/hour
Answer:
(2.3, 4.75)
Step-by-step explanation:
The point where 2 lines intersect is the solution to the system of equations.
For the triangle, you do 1/2*b*h
Where b is the base and h is the height
So, 1/2*9*7 which is 31.5
For the rectangle, we use the formula l*w
Where l is the length and w is the width
So we do 9*12 which is 108
The w e plus both values together to get the total area of the figure
108+31.5 is 139.5 ( which is roughly 139)
So, the answer to your question is option c
