In 1997, superman’s cape from the 1978 movie superman was sold at an auction. the winning bid was $17,000. question 1 write an inequality that represents the amounts of all the losing bids. let b represent the amount of a bid.

The inequality is :

Step-by-step explanation:

Let b represent the amount of a bid.

The winning bid was $17,000.

Now we know that the wining bid must have been the highest value bid and all other bids or b are smaller than the winning bid.

Therefore, the inequality that represents the amounts of all the losing bids is :

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
