I believe that none would be irrational; an irrational number can't have terminating or repeating decimals. 3/8= .375, (56/8)^4=7^4=2,401, 36^4/4^4=6561, and .19 repeating is a repeating decimal.
Hey there! :D
7(2x+6)=1
Use the distributive property. Multiply each number by each other.
7*2x= 14x 7*6= 42
14x+42=1
Subtract 42 on both sides.
14x= -41
Divide both sides by 14.
We know that 14 goes into -41 almost three times.
14*3= 42 (there is one left over)
-2 13/14 (we just need one more part of 14)
That is the simplified number.
I hope this helps!

Answer:
5,500
Step-by-step explanation:
25% of 2,750 is 687.5
687.5 times 4 is 2,750
2,750 times 2 is 5,500
so you would have $5,500 in total in your account in 4 years
Answer:
<em>You would need 5,555,556 hours to count 1 billion.</em>
Step-by-step explanation:
<u>Proportions</u>
If you count one number every 20 seconds, then you can count 3 numbers in a minute.
Counting 3 numbers in a minute will allow counting 3*60 = 180 numbers in an hour.
At the same counting rate, if you wanted to count 1 billion numbers, we can calculate the hours needed by dividing:
1,000,000,000 / 180 = 5,555,555.55
Rounding to the nearest hour, you would need 5,555,556 hours to count 1 billion.
