Is a triangle with sides of length 6ft, 21 ft, 23 ft. A right triangle?

Mathematics

Answer:

No

Step-by-step explanation:

By using the Pythagoras theorem, it can be easily determined that whether the triangle is right triangle or not.

Thus, a^{2}+b^{2}=c^{2} where where a and b are the legs and c is the hypotenuse.

Let a=6ft, b=21ft and c=23ft, then

a^{2}+b^{2}=c^{2}

(6)^{2}+(21)^{2}=(23)^{2}

36+441=(23)^{2}

477=529

which is not possible, therefore the given triangle is not right triangle because it does not satisfy the Pythagoras theorem.

What is the volume of a sphere with a radius, r = 0.5?
sattari [20]

Answer:

V = 0.52 cm³

Step-by-step explanation:

radius r = 0.5 cm

volume V = 0.523333333 cm³

surface area A = 3.14 cm²

circumference C = 3.14 cm

In Terms of Pi π

volume V = 0.166666667 π cm³

surface area A = 1 π cm2

circumference C = 1 π cm

Agenda: r = radius

V = volume

A = surface area

C = circumference

π = pi = 3.1415926535898

Formulas:

Sphere Formulas in terms of radius r:

Volume of a sphere:

V = (4/3)πr³

Circumference of a sphere:

C = 2πr

Surface area of a sphere:

A = 4πr²

Find three consecutive even integers such that the sum of the least integer and the middle integer is 3030 more than the greates
Genrish500 [490]
X = <span> least integer
x + 2 = </span><span>middle integer
x + 4 = </span><span>greatest integer

x + x + 2 - (x + 4) = 3030
2x + 2 - x - 4 = 3030
x - 2 = 3030
x = 3030 + 2  
x = 3032  </span>← least integer

middle integer = x + 2 = 3034

greatest integer = x + 4 = 3032 + 4 = 3036

Check:
3032 + 3034 = 6066
3036 + 3030 = 6066
6066 = 6066
