I cant figure out the answer for this can you help me

RV = 5, AV = 9

Step-by-step explanation:

Two secants to a circle from an external point, then

The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is

4(4 + RV ) = 3(3 + 9), that is

16 + 4RV = 3 × 12 = 36 ( subtract 16 from both sides )

4RV = 20 ( divide both sides by 4 )

RV = 5

and AV = 4 + 5 = 9

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

answer: 2530

hope this
