Answer:

Your answer is D

Step-by-step explanation:

Punching in those equations into my calculator, A, B, and C have all come up as non rational, because $\sqrt{11}$ isn't a rational number. It can become rational as soon as you multiply it with another number.

How many different towers can you make using one red, one blue and one yellow block?

icang [17]

You can make 6 different towers. If red was at the bottom, there'd be two different possibilities for that: red, yellow, blue, and red, blue, yellow. Same for if blue was at the bottom: blue, red, yellow, and blue, yellow, red. Yellow also applies: yellow, red, blue, and yellow, blue, red. 3*2=6, so 6 possible towers.

Golfer had the lowest number of strokes per hole is Alicia  = 4.

Step-by-step explanation:

We have , Three different golfers played a different number of holes today. Rory played 999 holes and had a total of 424242 strokes. Alicia played 181818 holes and had a total of 797979 strokes. Rickie played 272727 holes and had a total of 123123123 strokes. We have to find , Which golfer had the lowest number of strokes per hole :

Rory:

Number of strokes per hole = $\frac{424242}{999} = 425$

Alicia:

Number of strokes per hole = $\frac{797979}{181818} = 4$

Rickie:

Number of strokes per hole = $\frac{123123123}{272727} = 451$

∴ Golfer had the lowest number of strokes per hole is Alicia  = 4.
