Hello! I'm stuck on Pythagorean theorem in geometry. There are some numbers that suppose to have a line on top but I don't know

how to put it on top of the number, I just put this `. So, here's the problem: Which side lengths form a right triangle? A. 2,2, v```4``

<u>Choice A: </u>2,2, \sqrt{4}<u />

<u>Choice B: </u>9, 40, 41

<u>Choice C: </u>\sqrt{5}, 10$ and  \sqrt{125}

Answer:

(B)9, 40, 41

Step-by-step explanation:

To check if the sides form a right triangle, you check to see if they satisfy the Pythagorean theorem.

Hypotenuse^2=Opposite^2+Adjacent^2

Note that the longest side length is always the hypotenuse.

<u>Choice A: </u>2,2, \sqrt{4}<u />

Now, \sqrt{4}=2

Therefore:

2^2\neq 2^2+2^2\\4 \neq 8

These side lengths form an equilateral triangle. They do not satisfy the theorem.

<u>Choice B: </u>9, 40, 41

The longest side length is 41.

41^2=1681

40^2+9^2=1681

Therefore:

41^2=40^2+9^2

These side lengths form a right triangle.

<u>Choice C: </u>\sqrt{5}, 10$ and  \sqrt{125}

\sqrt{5} \approx 2.24 \\ \sqrt{125}\approx11.18

Therefore, the longest side length is \sqrt{125}

(\sqrt{125})^2=125\\(\sqrt{5})^2+10^2=5+100=105\\\\(\sqrt{125})^2 \neq (\sqrt{5})^2+10^2

These side lengths do not form a right triangle.

FrozenT [24]

Answer:

Lisa spends $138.40 on school lunches in 16 weeks.

Step-by-step explanation:

You have to multiply 8.65 by 16, since 8.65 is how much money Lisa spends each week for lunch, then you multiply by 16 since the problem calls for 16 weeks, then you get your final answer of $138.40.

Drag and drop the constant of proportionality into the box to match the table. If the table is not proportional, drag and drop "
Travka [436]

Answer:  3/2

Step-by-step explanation:

Since, two variables are called proportional if there is always a constant ratio between them.

And, The constant is called the coefficient of proportionality or proportionality constant.

Let x and y are  proportional to each other.

Therefore, x ∝ y ⇒ y=kx

Where k is any constant.

For, x=2 and y=3 k= 3/2

For, x=4 and y=6, k=3/2

For x=6 and y=9, k= 3/2

Since, here the value of k is constant.

Therefore, k is the coefficient of proportionality.

And, given table is propositional.
