Find x. round to the nearest tenth if necessary. assume that segments that appear to be tangent are tangent.
a. 5
b. 2.8
c. 3.5
d. 4

x = 4

Step-by-step explanation:

The formula for this, filled in with our specifics, is

which simplifies to

so

x = 4

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

i those same problems in math and dont know how to do them
