Elsa went for a drive in her new car. She drove 345.6 miles at a speed of 54 miles per hour. For how many hours did she drive

6.4

Step-by-step explanation:

You could use a calculator

Or

Do 345.6/54 and get 6.4

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

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).
