Nadia is a stockbroker. She earns 11% commission each week. Last week, she sold 7,200 worth of stocks. How much did she make last week in commission? If she averages the same amount each week, how much did she make in commission in 2011. (that last part literally makes no sense to me please help)

She made 792 dollars that week. I'm assuming it is just asking for the yearly commission she made. That would be 41,184 dollars a year.

Step-by-step explanation:

7200 x 0.11 = 792 Weekly

52 Weeks in a year

792 x 52 = 41184 Yearly (if that's what it's asking for)

answer: the value of x is 7cm

step-by-step explanation:

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
