Let the time = x
Distance = Speed x time
One train is 75x, the other train 85x
Add together to equal total distance:
75x + 85x = 384
Simplify:
160x = 384
Divide both sides by 160:
x = 384 / 160
x = 2.4 hours
I dont know if this helps since no one else is answering I’d like to help
To find slope.. the M in the slope formula of y=Mx+b represents slope
So as long as you know what point on the graph represents what then it should be easy
In most cases.. finding slope is where the line meets on the x axis
Answer: your answer would be 3
Step-by-step explanation:
To find the surface area of a cylinder, use the formula SA = 2(pi)(radius^2) + 2(pi)(radius)(height).
So now, plug in what you know.
SA = 2(3.14)(5^2) + 2(3.14)(5)(9)
SA = (6.28)(25) + (6.28)(45)
SA = 157 + 282.6
SA = 439.6 square cm
439.6 square cm is your surface area
The answer should be either b or d but i’m not too sure
