Find the area of the triangle (5.4cm)base

Mathematics

One of the many ways to solve the area of a triangle is to divided by two the product of its base (b) and height (h). Which can be expressed as,
 
                                                   A = (b x h) / 2

Substituting the given base and height to the equation,
                                   
                                           A = (5.4 cm x 2 cm) / 2 = 5.4 cm^2

Therefore, the area of the triangle is 5.4 cm^2.

azamat

Answer:

=3

=2

Step-by-step explanation:

12−5+6=0

using the Quadratic Formula where

a = 1, b = -5, and c = 6

=−±2−4‾‾‾‾‾‾‾‾√2

=−(−5)±(−5)2−4(1)(6)‾‾‾‾‾‾‾‾‾‾‾‾‾‾√2(1)

=5±25−24‾‾‾‾‾‾‾√2

=5±1‾√2

The discriminant 2−4>0

so, there are two real roots.

Simplify the Radical:

=5±12

=62=42

which becomes

=3

=2

hope this helps :)

GEOMETRY! PLEASE SHOW YOUR WORK. (updated picture)
Orlov [11]

Given:

The base of the given triangle has two part:

Left( left side of the hypotenuse) = 25

Right ( right side of the hypotenuse) = x

The altitude (h) = 60

To find the value of x.

Formula:

By Altitude rule we know that, the altitude of a triangle is mean proportional between the right and left part of the hypotenuse,

\frac{left}{altitude} =\frac{altitude}{right}

Now,

Putting,

left = 25, altitude = 60 and right = x we get,

\frac{25}{60} =\frac{60}{x}

or, (25)(x )=(60)(60) [ by cross multiplication]

or, x = \frac{3600}{25}

or, x = 144

Hence,

The value of x is 144.

Each cube in this rectangular prism is 1 cm3.What is the volume of the rectangular prism?
Lelechka [254]

Answer:

Volume of rectangular prism = 20\ cm^3

Step-by-step explanation:

Given rectangular prism is made up of small cubes of volume 1 cubic centimeter.

To find volume of rectangular prism.

Solution:

Volume of rectangular prism is = length\times width \times height

We know that all sides of a cube are equal in measure.

So, we will count the number of cubes on each side to get the exact measure.

Length side = 4 cubes = 5 cm

Width side = 2 cubes = 2 cm

Height side = 2 cubes = 2 cm

Thus volume of rectangular prism =  5\ cm\times 2\ cm \times 2\ cm

Volume of rectangular prism = 20\ cm^3

Apply the rule (-x, y - 2) to the following point, what is the result?
BaLLatris [955]

Answer: Second Choice. (3, 3)

Step-by-step explanation:

<u>Given point</u>

(x, y) = (-3, 5)

<u>Given the rule for application</u>

(-x, y - 2)

<u>Determine the new x-value</u>

x = -3

-x = - (-3) = 3

<u>Determine the new y-value</u>

y = 5

y - 2 = (5) - 2 = 3

Therefore, the result is \Large\boxed{(3,~3)}

Hope this helps!! :)
