Will reward brainliest test the conditional statement and it’s converse to determine whether the following biconditional is true. a number is divisible by 10 if and only it is divisible by 5 a) it is false because at least one part of the biconditional is false b) it is true because both parts of the biconditional are true c) it is true because at least one part from the biconditional is true d) it is false because both parts of the biconditional are true

Option A. is the correct option.

Step-by-step explanation:

If a number is divisible by 5 it is not necessary that the number will be divisible by 10.

For example: 25 is the number divisible by 5 but not divisible by 10.

Or in other words a number divisible by 5 should be even to be divisible by 10.

So for the conditional statement : A number is divisible by 10 if and only if it is divisible by 5 will be false because any one out of these two statements is false. We know biconditional is true only when both the statements are true or false means both the statements should have same truth value.

Therefore Option A. is the correct option.

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
