You can cancel the subtraction sign and the negative sign to make -5.9+(-8.7)+12.3 Add the negatives 5.9 and 8.7, and the answer of that is -14.6. Subtract 12.3 from 14.6, and the answer is C.

Alchen [17]

Answer:

15 outcomes

Step-by-step explanation:

We have three choices of ice cream containers.

We have five choices of ice cream flavors.

We are asking for a single scoop.

Using the cake cone 5 times for each flavor, we get 5 possibilities. Repeat this with the other two container choices, and we get 3 * 5 = 15.

Hope this helped! :D

Answer:

<em>The second figure ( rectangle ) has a longer length of it's diagonal comparative to the first figure ( square )</em>

Step-by-step explanation:

We can't confirm the length of these diagonals based on the appearance of the figure, so let us apply Pythagorean Theorem;

This diagonal divides each figure ( square + rectangle ) into two congruent, right angle triangles ⇒ from which we may apply Pythagorean Theorem, where the diagonal acts as the hypotenuse;

5^2 + 5^2 = x^2 ⇒ x is the length of the diagonal,

25 + 25 = x^2,

x^2 = 50,

x = √50

Now the same procedure can be applied to this other quadrilateral;

3^2 + 7^2 = x^2 ⇒ x is the length of the diagonal,

9 + 49 = x^2,

x^2 = 58,

x = √58

<em>Therefore the second figure ( rectangle ) has a longer length of it's diagonal comparative to the first figure ( square )</em>
