Answer:

A, B and C

Step-by-step explanation:

Given any three side lengths of a right triangle, the longest side is the hypotenuse.

The side lengths  of a right triangle must satisfy the <u>Pythagorean Theorem. </u>

Pythagorean Theorem: Hypotenuse^2=Opposite^2+Adjacent^2

<u>Option A:</u> 3, 6, \sqrt{45}

(\sqrt{45})^2=3^2+6^2\\45=36+9\\45=45

True

<u>Option B:</u> 2.5, 6, 6.5

6.5^2=6^2+2.5^2\\42.25=36+6.25\\42.25=42.25 (TRUE)

<u>Option C:</u> 4, 8, \sqrt{80}

4, 8, \sqrt{80}\\( \sqrt{80})^2=4^2+8^2\\80=16+64\\80=80 (TRUE)

Since all are true, the side lengths in Options A, B and C forms a right triangle,

pogonyaev

Answer:

4\frac{7}{12} cups of Salsa.

Step-by-step explanation:

Flora is making Salsa for a party.

Every 1 cup of chopped tomatoes makes 2\frac{3}{4} = \frac{11}{4} cups of Salsa

She uses 1\frac{2}{3} = \frac{5}{3} cups of tomatoes

1\frac{2}{3} cups of tomatoes makes:

\frac{5}{3} ×  \frac{11}{4} ÷ 1 = \frac{55}{12} = 4\frac{7}{12} cups of Salsa.
