Ian has 12.2 ounce bottle of ketchup. he uses 1/20 of the ketchup every time he has a buffalo burger. how many ounces of ketchup are left after ian has eaten 4 buffalo burgers.

9.76 ounces

Step-by-step explanation:

Ian has 12.2 ounce bottle of ketchup.

He uses of the ketchup every time he has a buffalo burger.

× 12.2

= 0.61 ounces every time

He has eaten 4 buffalo burgers. So he used ketchup = 0.61 × 4

                                                                                        = 2.44 ounces

Now the amount of ketchup are left = 12.2 - 2.44

                                                           = 9.76 ounces

9.76 ounces of ketchup are left after Ian has eaten 4 buffalo burgers.

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

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.
