Along strand of spaghetti is folded once. if this is cut 20 times, how many pieces of spaghetti will there be?

40 pieces.

Step-by-step explanation:

folding it will give us 2 strands instead of 1, which is double. we would then multiply 20 by 2 which gives us 40. hope I helped!

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).
