Acertain shade of pink is created by by adding 3 cups of red paint to 7 cups of white paint. how many cups of red paint should be added to 1 cup of white paint. cups of white paint. cups of red paint 1. ? 7. 3 and what is the constant of proportionality?

→[ Certain shade=red paint+ white paint]

→3 cups of red paint=7 cups of white paint

Dividing both side by 7,we get

→ 1 cup of white paint=3/7 cups of white paint

So, 3/7 of a cup should be added to 1 cup of white paint to make certain kind of shape.

Cups of white paint: Cups of red paint= 1. :

k= is constant of proportionality.

0.4286 cups or of red paint should be added to 1 cup of white paint.

is the Constant of Proportionality.

Step-by-step explanation:

For a certain pink shades , 3 cups of red paint requires 7 cups of white paints.

So, according to information, 7 cups of white paints need to 3 cups of red paints.

So, 1 cup of white paint will need : of red paint.

0.4286 cups or of red paint should be added to 1 cup of white paint.

Cups of red paint ∝ Cups of white paint

(Cups of red paint) = k × (Cups of whitepaint)

k = Constant of Proportionality

is the Constant of Proportionality.

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
