A class used cars and vans to go on a field trip because all of the buses were already in use. They used 9 vehicles to go on the trip. Each car holds 3 students and each van holds 13 students. If 97 students went on the trip, then how many of each type of vehicle did the class use?

They used 7 vans and 2 cars.

Step-by-step explanation:

With 7 vans, they can hold 91 students and with 2 cars, the can hold 6 students. 91+6=97 students.

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).
