A triangle has sides of lengths 13, 21, and 24. is it a right triangle? explain
mel-nik [20]
<span>No, it doesn't. To find out if it's a right angled triangle, we use Pythagorean triple. It states that the square of the hypotenuse (the longest side) is equal to the sum of the squares of the opposite and adjacent sides. Obviously, the longest side, which is our hypotenuse is 24. So we want to find out whether the square of our hypotenuse is equal to the sum of the squares of the other two sides i. e 13 and 21. 24^ 2 = 576 ; 13^2 = 169 ; 21^2 = 441; So is 576 = 169 + 441. An emphatic No: hence the triangle isn't right angled since it doesn't satisfy pythagorean triple.. A^2 is not equal to B^2 + C^2 where a is the hypotenuse and b and c the opposite and adjacent sides.</span>

Hom many 1/4 ft fish food boxes could fit in a 3 3/4 ft box
IrinaK [193]

Answer : There are 13 fish food bags are could fit in a box of size 3\frac{1}{4} ft.

Explanation :

Length of box = 3\frac{3}{4} ft

Length of fish food box = \frac{1}{4} ft

Number of fish food boxes could fit in a box = \frac{\text{length of a box}}{\text{length of fish food box}}

Number of fish food boxes could fit in a box  =\frac{3\frac{1}{4}}{\frac{1}{4}}\\=\frac{\frac{13}{4}}{\frac{1}{4}}\\= \frac{13}{1}

Hence, there are 13 fish food bags are could fit in a box of size 3\frac{1}{4} ft.

Find the error with this proof and explain how it mat be corrected in order to clearly prove the equation.
enyata [817]

Answer:

Step-by-step explanation:

It is true that for any given odd integer, square of that integer will also be odd.

i.e if m is and odd integer then m^{2} is also odd.

In the given proof the expansion for (2k + 1)^{2} is incorrect.

By definition we know,

(a+b)^{2} = a^{2} + b^{2} + 2ab

∴ (2k + 1)^{2} = (2k)^{2} + 1^{2} + 2(2k)(1)\\(2k + 1)^{2} = 4k^{2} + 1 + 4k

Now, we know 4k^{2} and 4k will be even values

∴4k^{2} + 1 + 4k will be odd

hence (2k + 1)^{2} will be odd, which means m^{2} will be odd.

Anettt [7]

Answer:

<h3>Volume of cylinder = 6,330.24 cm</h3>

Solution:

Volume of cylinder = area of base × altitude

Volume = πr² × altitude

V= 3.14 × 12² × 14

V = 3.14 × 144 × 14

V = 6,330.24 cm
