1.solve for r.

s=2πrh

2.solve for c.

a(b − c)=d

3.solve for b.

d = 3a + 3b

4.the formula for a trapezoid relates the area a, the two bases, a and b, and the height, h.

a=(a+b) over 2 h

solve for a.

5.the formula for the perimeter of a rectangle is p=2(l+w).

solve for l.

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

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).
