Question

4. Mrs. Clarkson designed a rectangular garden with a length of 15 meters and a width of 8 meters. She plans to build a walkway through the garden from one corner to the next. What measure is closest to the length of the diagonal walkway?

8 meters
11 meters
17 meters
23 meters

7. What is the square root of 36/49

18/25
20/27
6/7
8/9

4. 17 meters
5. 25
6. Whole number
7. 6/7
Am I right?

Answer 1

#5
25 is a perfect square ---- 5^2 = 25 , but
27 is a perfect cube --- 3^3 = 27

#6 is incorrect
√9 - 7
= 3-7
= -4, which is an integer
Whole numbers are positive integers

I agree with the others.

Answer 8

Number four explanation:

Formula:
a^2+b^2=c^2

(it doesn't matter which number is in a or b, as long as the bigger number is on c)
8^2+15^2=c^2

8*8....15*15
64+225=c^2

√289=√c^2

17=c

That is how I got 17 as the answer.

Further explained:
The question said, "Mrs. Clarkson designed a *rectangular* garden." The problem also said, "What measure is closest to the length of the *diagonal* walkway?" This basically means that she has a Pythagorean Theorem problem. If you split that rectangle diagonally you get two triangles.

So yes, you are correct for the fourth.
As for everyone else with not knowing the explanation, I hope that helped.
