Which is the same as moving the decimal point 3 places to the left in a decimal number
Gekata [30.6K]
The answer would be B: Dividing the number by 1000

Every time you move the decimal, add a zero. Since the decimal is moved three times, there are three zeroes. When you move left, the number is getting smaller so it is division.

Frank currently rents an
hammer [34]

9514 1404 393

Answer:

  • monthly payment $690.25
  • total interest $123,490
  • total repaid $248.490
  • difference from rent $9.75

Step-by-step explanation:

Frank's monthly payment will be $690.25.

The total of all payments will be $690.25 × 360 = $248,490.00.

The interest Frank will pay is $248,490 -125,000 = $123,490.00.

The difference between Frank's rent and his loan payment is ...

   $700 -690.25 = $9.75

Can the values be added or subtracted? If one value needs to be converted to another, describe the conversation. 32.8 kg+64.3 km
Kay [80]

Those two quantities cannot be added.

In order to add or subtract quantities, they don't necessarily both need to
have the same units, but both must have the same physical dimensions
so that one unit can be converted to be the same as the other unit.

"Physical dimensions" are things like mass, length, area, volume, time,
force, speed, etc.

In this problem, one quantity has the unit 'kg'so its physical dimension is <em><u>mass</u></em>. 
The other quantity has the unit 'km' so its physical dimension is <em><u>length</u></em>.  Obviously
these physical dimensions are different, so there's no way that either unit can be
converted to match the other one, and the quantities can't be added.
