I’m not exactly sure what the question is asking, but assuming that the equation is r=10b^2, then the answer would be r=40.

Answer:
£500
Step-by-step explanation:
ratio of money = 3 : 1 = 3x : x ( x is a multiplier )
winner receives £250 more than the runner up, that is
3x = x + 250 ( subtract x from both sides )
2x = 250 ( divide both sides by 2 )
x = 125
total prize money = 3x + x = 4x = 4 × 125 = £500
Answer: d
Step-by-step explanation:
Note that the distance to the tower and the height of the tower create a right triangle at the base of the tower. The equation to find the height of a right triangle is to multiply the length times the tangent of angle β.
Given:
b = a · tanβ
tan(30°) = √3/3
Step 1: Solve
b = (30/1) · (√3/3)
b = (30 · √3) / (1 · 3)
b = (30√3) / (3)
b = 10√3
