Answer:
Greg has 39 remaining blocks that are not used in the tower.
Step-by-step explanation:
According to the question, Greg started with 60 building blocks. However, his sister gives him 17 more blocks. The key word 'more' means we need to add these blocks to the original 60: 60 + 17 = 77. Greg then decides to use 38 blocks to make a tower. Since he is using these blocks from his total of 77, we need to subtract this number to see how many he has left: 77 - 38 = 39. This means that Greg has 39 blocks left that were not used to build his tower.
You have to find out how much is it per Apple, to do that you divide 4 by $4.80 which is 0.8333...
Then you have to multiply that number by 2 which is 1.6666..
You multiply by 2 because if one pound is .83 and you need two more pounds to equal 6.
4.80+1.67=$6.47
81 is a composite number because it is the only number in the list that is not prime and is divisible by smaller primes.
Answer:
3 cm on the map represents 31.5 km in reality.
3cm : 31.5 km
1cm : 31.5/3 km
1cm : 10.5km
So the scale on the map is 1cm represents 10.5 km.
