The rules of rational numbers is that if it repeats or ends then it’s rational. Answer A is wrong because -5*4/11 equals -1.81818181... it keeps repeating the same numbers making it rational. Answer C, 7.608 ends, meaning no numbers come after the last one in this case it’s 8. Answer D I think would be wrong since it says 18.46 continuing (I assume it’s 18.46464646...) meaning it repeats which leaves us with the root of 31 which is 5.56776436... the number don’t stop and they don’t repeat making it irrational. So if another question comes up asking if it’s rational or irrational just ask yourself does it repeat or end? Or does it go on forever like PI.

I think its the second one, the answer does not have a definite and, and cannot be put into a ratio.

Together, teammates Pedro and Ricky got 2679 base hits last season. Pedro had 283 more hits than Ricky. How many hits did each p
Sergio [31]

Answer:

Pedro: 1481 Base hits

Ricky: 1198 Base hits

Step-by-step explanation:

First, take the total amount of base hits last season 2679, then subtract how many more Pedro has 283.

2679 - 283 = 2396 now divide the sum in half  2396 ÷ 2 = 1198 that gives you how many each player has, you're then going to add the amount that you took off to only Pedras total since he had 283 more

Pedro: 1198 + 283 = 1481

Ricky: 1198

Please help, thank you!

Answer:

37 and 26

Step-by-step explanation:

Let the bigger number be x and the smaller number be y.

Then the two numbers total 63 will give us:

y+x=63------>eqn1

The two numbers have a difference of 11.

y-x=11------->eqn2

We add equations 1 and 2 to obtain:

2y=74

Divide both sides to get:

y=37

Put y=37 into eqn2 to get:

37-x=11

x=37-11

x=26

This larger number is 37 and the smaller number is 26

Which of the following would be the most appropriate unit to measure the volume of oil in a large tank?
Elenna [48]

Answer:

Option C

Step-by-step explanation:

Option D's unit is not used in volume measurement. A "ton" is 2,000 lbs. Pounds are not used to measure volume.

Since we are looking at the volume of a "large tank", then a quart and a pint would be too small, and therefore, not the most appropriate units to measure the volume of the tank with.

A "kiloliter" is equivalent to 1,000 liters. Note that the prefix "Kilo-" means 1,000. A kiloliter would be appropriate for measuring the volume of a large object, in this case a oil tank. It is the most appropriate out of the options given.

Option C should be the correct answer.
