Asledgehammer weighs 18 pounds on earth and 4 pounds on the planet namar based on the numbers an 80 pound earthling would weight about pounds on namar

A sledge hammer weighs 18 pounds on earth, and 4 pounds on Namar

Divide 18 with 4

18/4 = 4.5

Ratio of Earth/Namar: 4.5/1

We are solving for an 80 pound earthling.

Divide 80 with 4.5

80/4.5 = 17.778 

Round. Because 7 is greater than 5, round up.

18, or C) is your answer

hope this helps

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
