Answer:

Step-by-step explanation:

Use proportions to figure this out.  On the top you'll have miles and on the bottom you'll have minutes.  I am going to change 3/4 to .75 and 1/8 to .125:

\frac{miles}{minute}:\frac{.75}{.125}

We want to know how many miles per 1 minute that is.  So we have the unknown on top in a new ratio, with 1 on the bottom:

\frac{miles}{minute}:\frac{.75}{.125}=\frac{x}{1}

This second ratio is allowing us to calculate what the decimal ratio is in miles per 1 minute.  Cross multiply to get

.125x = .75 so

x = 6 miles

That tells us that the decimal ratio is equivalent to 6 miles per minute

Answer:

angle Y = 90 degrees

Step-by-step explanation:

Since it is stated that angle x forms a straight line with the 50 and 50 degree angles, and that angle x is vertical to angle y, we can do 40+50+y=180 to find angle Y.
