Delia went to a market to buy 4.5 pounds of sliced fruit in a container she paid with a $20 bill and a $5 bill and received $4.6
andreyandreev [35.5K]
20+5=25 then 25-4.67=20.33 so then you do 20.33/4.5=4.5 so the cost for one pound of fruit is $4.57. Hope this helps :)

In a right triangle abc, cd is an altitude, such that ad=bc. Find ac, if ab=3 cm, and cd= square root 2 cm.
Mashcka [7]

      <u>ΔACB</u>                                               <u>ΔCDA</u>

AC² + BC² = AB²                           AD² + CD² = AC²  

          BC² = AB² - AC²                 BC² + CD² = AC²        (AD=BC is given)

                                                                 BC² = AC² - CD²

                         AB² - AC² = AC² - CD²         (both sides were = to BC²)

                         AB² + CD² = 2AC²

                         (3)² + (√2)² = 2AC²            (AB=3 and CD=√2 were given)

                          9  +   2    = 2AC²

                               11        = 2AC²

                                \frac{11}{2}        = AC²

                                \sqrt{\frac{11}{2} }     = AC

                                \frac{11\sqrt{2} }{2}      = AC
