Randy had a lot of homework tonight. he needs to work for 45 minutes on social studies 40 minutes on science and 1 hour and 15 minutes on math. it will also take him 10 minutes to get ready for bed. if he wants to be in bed at 10: 00on what time does he need to start his homework?

He needs to start his homework at 7:10.

Step-by-step explanation:

Hi, to answer this question we have to add all the times:

45 min (social studies)

40 minutes (science)  

75 minutes (math) (1 hour and 15 minutes = 75 minutes)

10 minutes (to get ready)

Mathematically speaking:

45+40+75+10 = 170 minutes

If 60 minutes equals to 1 hour:

170/60 = 2.83 =  

The hour is the integer part (2 hours)

The minutes is the decimal part multiplied by 60

0.83 x 60 = 50 minutes

So, 2 hours and 50 minutes, before 10:00.

10:00 -2:50 = 7:10

45 degres

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
