Knowing that a gallon of ice cream can feed ten people, you need to model the number of gallons you buy based upon the number of people attending your party.
function family:
explanation:

y = n/10

Step-by-step explanation:

ice cream buckets needed = #people attending / 10

y = n/10

where y = ice cream buckets, and n = # of people attending party

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
