Diamond, Tricia, Brandi and Ellie were counting how many outfits they had. Diamond had 2/10 of the total outfits. Tricia had 4/20 of the outfits and Brandi had 2/5 of the outfits what fraction of the outfits were ellie's?

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.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

answer: your answer is a
