How many seconds after Kristen gets home is her dinner ready?

1,020seconds

Step-by-step explanation:

If Kristen gets home by 5:34pm and dinner is ready by 5:51pm, dorat we need to know interval of time between when when Kristen got home and the dinner time. Since the difference is within minutes, the distance will be the difference between the minutes hand .e 51-34 which is 17minutes.

To get the amount of seconds within this period, we will have to convert 17mimutes to seconds.

1minutes = 60seconds

17minutes = x seconds

Cross multiplying

x = 17×60

x = 1020seconds

1020 seconds

Step-by-step explanation:

Time Kristen gets home =5:34 p.m

Time when her dinner is ready =5:51 p.m

Difference in Time =5:51 p.m-5:34 p.m=17 minutes

There are 60 seconds in 1 minute

Therefore:

There will be 17 X 60 seconds in 17 minutes.

The number of seconds when Kristen's dinner is ready after she gets home

=17 X 60

=1020 seconds

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.
