How do you write 7 x 68 in distributive property

Mathematics
1 answer:

Answer:

  7×(60 +8)

Step-by-step explanation:

There are many ways to do it. The one we usually use for multiplication by hand is ...

  7×68 = 7×(60 +8) = 7×60 +7×8

__

Just to show you some other possibilities, we could do ...

  7×68 = 7×(34 +34) = 7×(20 +20 +20 +8) = (5 +2)×68

The last one is interesting in that mental multiplication by 5 and 2 are generally pretty easy. (5+2)×68 = 340 +136 = 476

That is actually easier thatn it looks

here is  a tip
write that thing apart since they are all multiplication like this:
V=(1/3)pir^2  h
now just divide the whole equaiton by ((1/3)pir^2)
or if you don't like dividiing by fracitons, times both sides by 3/1 to clear fraction to get
3V=pir^2h
divide both sides by pir^2
(3v)/(pir^2)=h

beks73 [17]
50 calories are consumed per milefor 15 miles per hour, calories consumed
= 50*15
=750 calories per hour, 
this is equal to 750/3600 
= 0.2083 calories/second, given that, 
1 calorie per sec 
= 4.19 watt, the average power output
= 0.2083*4.19
= 0.873 Watts
