A. 78 km/h

B.  9.75 km/l

C. 64.28571 km /h

Step-by-step explanation:

2.5 hours, drove 195 km, used 20 liters for whole journey

A. avg speed

speed = distance / time

speed = 195 km / 2.5 hours

speed = 78 km per hour

B. gasoline consumption rate in km/l

rate = kilometers / liters

rate = 195 km / 20 l

rate = 9.75 km/l

C. avg speed of 110 km/h for 45 mins, what is avg speed for remaining part?

distance = speed * time

distance = 110 km/h * 0.75 h

distance = 82.5 km

total distance = 195, 195-82.5, he has 112.5 km left to go for the trip

105 minutes left (2.5*60 - 45 = 105)

speed = distance / time

speed = 112.5 km / 1.75 h

speed = 64.28571 km /h

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
