Show that the area of a right triangle of sides 5, 12 and 13 cannot be a square
S_A_V [24]

Answer and Explanation:

Given : Sides of right triangle 5,12 and 13.

To find : Show that the area of a right triangle of sides 5, 12 and 13 cannot be a square ?

Solution :

If 5,12 and 13 are sides of a right angle triangle then

13 is the hypotenuse as it is largest side.

then we take perpendicular as 12 and base as 5.

The area of the right angle triangle is

A=\frac{1}{2}\times b\times h

Here, h=12 and b=5

A=\frac{1}{2}\times 5\times 12

A=5\times 6

A=30

The area of the right angle triangle is 30 units.

30 is not a perfect square as 30=2\times 3\times 5

There is no square pair formed.

How is mental math to add with decimals different from adding whole numbers using mental math.
Anna71 [15]
When using mental math to solve problems with decimals, it is harder to keep track of what number goes where and where the decimal spot goes as well. Although, with whole numbers in mental math, it is a lot easier to solve since there is no decimal and less numbers (unless you are doing whole number math with a large amount of numbers).

What’s the difference???<br> Help please
RideAnS [48]

Answer: D

Step-by-step explanation:

An equation would look like this:

x+1=3

An expression would look like this:

x+1

As you can see, an expression has no equal sign. Conversely, an equation does. That is the primary difference between a(n) (algebraic) expression and equation.

What is the total surface area of the rectangular pyramid below?
Sergio [31]

Answer:

Step-by-step explanation:

Alright, lets get started.

The total surface area of rectangular pyramid will be the area of all four faces and area of base.

The faces are triangular, so area will be = \frac{1}{2}*base*height

Area of face = \frac{1}{2}*16*14=112

Another face area = \frac{1}{2}*12*15=90

Each face has its similar another face. So total area of faces will be = 112+112+90+90=404

Area of base = 12*16=192

So total surface area = 404+192=596 square feet

Hence the total surface area is 596 square feet.   :   Answer

Hope it will help :)
