A+B=32 A:B is equivalent to 5:11

A= 10, B= 22

Step-by-step explanation:

A +B= 32 -----(1)

A: B= 5: 11

Rewriting the above ratio as a fraction:

Multiply both sides by B:

-----(2)

Substitute (2) into (1):

B= 22

Substitute B= 22 into (1):

A +22= 32

A= 32 -22

A= 10

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

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
