A. A hockey coach bought 20 pucks for a total cost of $47.50. The pucks used for practice cost $2.00 each, and the pucks used for games cost $2.75 each. Write a linear system to model this situation:

b. How many of each type of puck did the coach purchase?
Practice pucks: Game pucks:

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

d

step-by-step explanation:

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.

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
