Dwight spent $250 to rent a jet ski for 6 hours. the rental company charges a base rate of $150 for the first two 2 hours, and then an hourly rate for each additional hour, h. the equation 4h + 150 = 250 models dwight's cost of renting the jet ski. how much does each additional hour of rental cost?

25$

Step-by-step explanation:

4h+ 150= 250

subtract the 150 from 250 to get 100

4h =100

then divide 100 by 4

h=25

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.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
