Question 2
if a calculator is sold for $16.15, then the revenue in dollars, r, generated by this item is
given by the formula r=16 15q, where q represents the number of calculators sold. use
the formula to determine the revenue generated by this item if 28 calculators are sold

Revenue = $452.2

Step-by-step explanation:

Given,

The selling price of a calculator, P = $16.15

The given equation is R = 16.15*q

We know that, Revenue = Price*Quantity

If the selling numbers of calculators is 28,

according to the question,

Revenue = $16.15*28

Revenue = $452.2

That is an example of a linear equation. In this equation, if we increase the quantity sold, the revenue will increase automatically.

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

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.
