Today, Abigail has brought 12 sandwiches to share with friends at
practice. Unfortunately, her pet mouse got into her backpack and ate parts
of 5 of them. What percent of the sandwiches are still in good shape?

58%

Step-by-step explanation:

The first thing that you have to do if figure out how many sandwiches are left we do this by the total - bad sandwiches = good sandwiches

12-5=7

There are 7 good sandwiches left. To figure out the percentage you do       =     now we fill in the parts the part is 7, the total is 12 and the % is x

=          now we cross multiply, 7 x 100 and 12 x X

700=12x          now we divide both sides by 12 so the x is alone

x = 58.33            now we round down because it ends in.3

x=58

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
