If I varies inversely with R and I = 0.25 when R = 18, which equation should be used to show this relationship?

1 answer:

7 0

Inverse relationships are of the form xy=k or if you prefer y=k/x so to find the constant we can say:

18(0.25)=k=4.5

So you could say: IR=4.5 or I=4.5/R

Solve for x does anyone know how to do this?

riadik2000 [5.3K]

Answer:

x = 9

Step-by-step explanation:

The sum of the 4 angles in a quadrilateral = 360°

Sum the given angles and equate to 360

90 + 109 + 9x - 5 + 85 = 360, that is

9x + 279 = 360 ( subtract 279 from both sides )

9x = 81 ( divide both sides by 9 )

x = 9

What number does the model below best represent?

umka21 [38]

Answer: 85 or 85% or 85/100

Step-by-step explanation:

This is because there are a total of 100 squares in the grid, and out of those 100 there are 85 squares shaded in. So the model best represents 85, 85%, or 85/100. These answers are dependent on what choices you have for the possible answer.

Identify as a direct variation, inverse variation or neither. is the cost of gasoline a direct or inverse variation with respect

I would say direct because the more gallons of gasoline used, the bigger the cost.
