15/6=2.5 which is the scale factor since they are similar triangles. We divide each side of the large triangle by 2.5 to get the sides for the small triangle since they are similar. 20/2.5=8cm
25/2.5=10cm
For the second problem, you put 15/6 and set in equal to x/8 when you cross multiply you get 6x=120 then you divide x=20
For the last problem, you divide 43,75 by 5 then multiply it by 400 to get the kiloliters which equals 3,500.
To find the acceleration of the bicycle rider, we are going to use the acceleration formula:

where

is the acceleration

is the initial speed

is the final speed

is the time
We know from our problem that increases his speed from 5 m/s to 15 m/s in 10 seconds, so his initial speed is 5 m/s and his final speed is 15 m/s; therefore,

,

, and

. Lets replace those values in our formula:



We can conclude that the acceleration of the bicycle rider 1 m/s^2
Answer:
625
Step-by-step explanation:
t= d/s
2500/4
Equation of line h is y=-2x-1
Slope is -2 (because it’s parallel)
so you have y=-2x+a
now you have to plug in the points it needs to pass through -9=-2(4)+a
do -2(4)
isolate a so then you would add the -8 to the other side
do the math of -9-(-8)
that’s how you get y=-2x-1
