First draw a rectangle. Label the length and the width. Then multiply 60 and 2. Once finished take a ruler and start drawing the tiles in the rectangle. If there are 12 tiles then you will need two boxes. If there are six tiles, then you will need one box. It's simple, just focus! Good luck.

Andreas93 [3]

Answer:

Diámetro = 8 metros

Step-by-step explanation:

La ecuación de la circunferencia esta en la forma general y para identificar su centro y su radio debemos llevarla a la forma canónica completando cuadrados:

x^{2} +y^{2} -28y + 180= 0

Solo necesitamos completar cuadrados en la variable y, sumando a ambos lados de la ecuación 196, que resulta de dividir 28 entre 2 y elevarlo al cuadrado

x^{2} +y^{2} -28y + 196 = -180 +196

Entonces obtenemos

x^{2} + (y-16)^{2} = 16

E identificamos que el radio del tanque es 4 metros y por tanto su perímetro es 8 metros

What is the approximate distance between the points (-5,1) and (-2,3) on a coordinate grid? Show me an example please
yaroslaw [1]

Answer:

d=\sqrt{13}\ units   or  d=3.61\ units

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

A(-5,1)\\E(-2,3)  

substitute the values

d=\sqrt{(3-1)^{2}+(-2+5)^{2}}

d=\sqrt{(2)^{2}+(3)^{2}}

d=\sqrt{13}\ units

d=3.61\ units
