Answer:
The wide would be 7.2 cm
Step-by-step explanation:
Let
x------> the wide of the proportional wall map
we know that
Using proportion
45/27=12/x
x=27*12/45
x=7.2 cm
First find the slope/rate of change of the table. Find the difference between the intervals of the x and y values of the table. Each time the x value decreases by 2 the y value decreases by 4. To find the rate of change divide the -4 by -2 to get 2 as the slope.
Set up an equation using values from the table to figure out the y intercept or b value.
-6=-4(2)+b
-6=-8+b. Add 8 from both sides
both sides to get b
2=b
The y intercept is (0,2)
The equation of the line is Y=2x+2
Plug in 0 for y into the lines equation to get the x intercept
0=2x+2
-2=2x. Divide by 2 to isolate x
-1=x
The x intercept is (-1,0)
Answer:
Step-by-step explanation:
this is confusing b/c they are asking about two trains traveling at differnt speeds, but.. if you put the speeds together and make one train... imaginary.. ofc... traveling at the speed of both trains combined... when will it be 50 miles from the station?
maybe you can solve that? I'll solve it below.. but.. if you can.. try it now, on your own
below is my answer... don't look until you have solved yours :P
80+70= 150kph
when will this have traveled 50Km?
you may be able to see that it will take 1/3 of an hour to travel 50 km
so 60 minutes times 1/3 = 20 minutes :)
