1) there are three colours of beads in a bag. the ratio of red to yellow beads is 8: 3. the ratio of green to yellow beads is 9: 2. what fraction of the beads are green?

2) if the mean of a thousand numbers is zero and all but one of the numbers is 1, the other number is -999. the mean on n numbers is m and all but one of the numbers is one more than m. what is the other number in terms of n and m?

b

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).
