Una botella pesa 1090kg cuando esta llena y 250g cuando esta vacía. ¿Cuanta masa de aceite contiene la botella?
Hitman42 [59]

Respuesta:

1089,75 kg

Explicación paso a paso:

Dado que :

Masa de embotellado lleno = 1090 kg

Masa de la botella vacía = 250 g

Masa de aceite que contiene la botella:

Expresando la masa de la botella cuando se llena en gramos:

1000 g = 1 kg

1090 kg = (1090 * 1000) = 1090000 g

La masa de aceite que contiene la botella es así:

Masa de la botella cuando está llena - masa de la botella cuando está vacía

1090000 g - 250 g = 1089750 g

Por tanto, la masa de aceite es 1089750 g

O 1089750/1000 = 1089,75 kg

Triangle ABC has vertices at (3,1) and (6,4).Rotate this triangle 180 degrees about the origin then reflect it over the Y-Axis.
Tems11 [23]

Answer:

3, -1

6,-4

IDK about the third vertices, you didn't give the original coordinates!

Step-by-step explanation:

180 degree rotation= (x,y) to (-x,-y)

3,1 goes to -3,-1

6,4 goes to -6, -4

IDK about the third vertice, you didn't mention it.

Reflection over y-axis= (x,y) to (-x,y)

-3, -1 goes to 3, -1

-6,-4 goes to 6,-4

hope this helps!

Aiden works at a garden center where he pots plants. It takes him 2 1/2 hours to pot 15 plants. How many plants can Aiden pot in
Troyanec [42]

Answer:

6\ plants

Step-by-step explanation:

Remember that

2\frac{1}{2}\ hours=\frac{5}{2}\ hours

Using proportion

\frac{15}{(5/2)}\frac{plants}{hours} =\frac{x}{1}\frac{plants}{hour}\\ \\x=15*2/5\\ \\x=6\ plants
