Finals question. will give brainliest (choose irrational or rational for each one)

The first choice would have to be irrational because Pi never ends.  The second one would be rational because the sentence says that because it says that because the left side is blank, this is a contradiction.  This shows that the answer has to be the opposite of the first one.  Finally, the third option would be Rational because the first sentence says "suppose 4x is irrational"... The last sentence says, "therefore, the assumption is wrong, and the number 4x is ".   Please let me know if I am wrong. I hope this helps:

Step-by-step explanation:

is there answer choices?

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
