324/5 = (321/5)4. Now we can evaluate 321/5.. This is the fifth root of 32, which equals 2. (25 = 32) .
Two prime numbers that are greater than 25 and less than 35 are; 29 and 31
cause the all the factors of 29 are 1,29 and of 31 are 1,31
Hope that helps :D
Answer: her call lasted for 44 minutes
Step-by-step explanation:
Linda purchase a prepaid phone card for $30. This means that the credit on her card is $30.
Long distance calls cost $0.17 each. Linda use her card only to make a long distance call. Assuming she made a total of x minutes of long distance calls, the cost would be $0.17x. The amount remaining on her card will be
30 - 0.17x
if the remaining credit on her card is $22.52, the number of minutes,x that the call lasted will be
22.52 = 30 - 0.17x
0.17x = 30 - 22.52
0.17x = 7.48
x = 7.48/0.17 = 44
<span>If a number is not a rational number, then it is not a whole number. The converse is true.
---> the sentence above is the only one that has true condition, true hypothesis and true conclusion.
You see:
></span><span>If a number is not a whole number, then it is not a rational number. The converse is false. ( converse must be true)
></span><span>If a number is a rational number, then it is a whole number. The converse is false. (converse must be true)
></span><span>If a number is not a rational number, then it is a whole number. The converse is false. (hypothesis should've been "then it is not a whole number")
</span><span>
In the Law of Detachment, if both conditional and hypothesis are true, then the conclusion is true.
</span><span>All whole numbers are rational numbers.
In the "If-the"n form: If a number is whole, then it is rational.
Given: 5 is a whole number.
Conclusion: 5 is rational.</span>
