Four students work to find an estimate for square root 54. Who is closest to finding the true estimate? (1 point)

Rhonda: "Use square root 16 and square root 25 to estimate."
Ricardo: "I use square root 25 and square root 36."
Riley: "It should be between square root 36 and square root 49."
Rhiannon: "Use square root 49 and square root 64 to estimate."***

Rhiannon is correct.

Well, let's see here. Rhonda's estimate would be 4 + 5, which is 9. Ricardo's estimate would be 5 + 6, which is 11. Riley's estimate would be between 6 and 7, which is pretty close. And Rhiannon's estimate would be 7 + 8, which is 15. I have to say, between all of these options, Riley seems to be the closest to the true estimate. So, I guess we could say that Riley is the winner here! But hey, at least they all gave it their square rootin' try!

Rhiannon is closest to finding the true estimate.

To determine who is closest to finding the true estimate for the square root of 54, we need to calculate the square roots provided by each student and compare them.

Rhonda suggests using the square roots of 16 and 25 to estimate. The square root of 16 is 4 and the square root of 25 is 5. Rhonda's estimate would be between 4 and 5.

Ricardo suggests using the square roots of 25 and 36. The square root of 25 is 5 and the square root of 36 is 6. Ricardo's estimate would be between 5 and 6.

Riley suggests that the square root of 54 should be between the square root of 36 and the square root of 49. The square root of 36 is 6 and the square root of 49 is 7. Riley's estimate would be between 6 and 7.

Rhiannon suggests using the square roots of 49 and 64 to estimate. The square root of 49 is 7 and the square root of 64 is 8. Rhiannon's estimate would be between 7 and 8.

Comparing all the estimates, we can see that Rhiannon's estimate, between 7 and 8, is the closest to the true estimate for the square root of 54. Therefore, Rhiannon is closest to finding the true estimate.
