D.) 2.13 < 2.3 is correct. This is stating that 2.3 is greater than 2.13, which is true. In the other possible answers, for example 4.15 > 4.51, this would be false because 4.15 is not greater than 4.51. The open end of the greater than or less than sign will always point to the bigger number.

If a house is 15 meters long and 12 meters wide how long is the diagonal of the house
Makovka662 [10]

Answer:

19.21m  is the diagonal

Step-by-step explanation:

We are looking for the diagonal, which makes it the hypotenuse of a right triangle, with the legs being 15 and 12

We can use the Pythagorean theorem

a^2 + b^2 = c^2

12^2 + 15^2 = c^2

144 +225 = c^2

369 = c^2

Take the square root of each side

sqrt(369) = sqrt(c^2)

19.209 =c

19.21 m = c
