the speed a car travels is inversely proportional to the time it takes to complete a 100 mile trip. which of the following graph
Tems11 [23]

Answer:

Inversely proportion states that a relationship between two variables in which the product is a constant.

If one of the variable increases, then the other decreases in proportion so that the product is unchanged.

If y is inversely proportional to x, then the equation is of the form

y = \frac{k}{x} ;  where k is the constant proportionality.

As per the given condition: Speed of a car is inversely proportional to the time it takes to complete a 100 mile trip,

Let x represents the speed of car and y represents the time taken.

From the given condition:

x \propto \frac{1}{y}

Then by definition of inversely proportional;

x = \frac{k}{y}         [Since, speed = \frac{Distance}{Time} ]

Here, k represents the distance(i.e constant) = 100 miles.

therefore, the equation becomes now;

x = \frac{100}{y} or

xy = 100

The following graph for the above equation as shown below :

Which price is cheaper? 20% off the original price of $29.99 or 10% off the original price of $26 for a book?
Archy [21]
20% off means that now it costs 80% of original price
80% = 0.8
costs 80% of (means here times (*))original price
29.99*0.8≈23.99

10% off means that now it costs 90% of original price
90%=0.9
costs 90% of (means here times (*))original price
26*0.9=23.40
23.99>23.40,
so is 
<span> 10% off the original price of $26 is cheaper</span>
