Ben frank is an electrician who installs lighting fixtures. he charges (in dollars) his clients 15h+40f where h is the number of hours worked and f is the number of fixtures installed.
how much does ben frank charge when he works 7 hours and installs 9 fixtures?

$465

Step-by-step explanation:

Given expression: , where  h is the number of hours worked and f is the number of fixtures installed.

To find total charges (in dollars) when he works 7 hours and installs 9 fixtures, substitute h=7 and f=9 in the given expression, we get

Therefore, Ben Frank charges $465 when he works 7 hours and installs 9 fixtures.

its kind of blurry. can you put a clearer pic?

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).
