123.51 divided by 2.3 show your work
Darya [45]

Answer:

53.7

Step-by-step explanation:

So first move the decimal in 2.3 by one to the left, making it 23. Now what you do to one thing you do to the other, now 123.51 becomes 1235.1. Now you have 1235.1 / 23. 23 goes into 1235; 53 times, leaving you with 16.1. Now we take 16.1 / 23. When you do that you get .7. Therefore your answer is 53.7

Hopefully this helped!

The density of aluminum is 2.375 grams per cubic centimeter. Find the volume of a portion of a sheet of aluminum that has a mass
abruzzese [7]
This is the concept of density, volume and mass of different materials; To calculate for the volume of an aluminium material with density of 2.375 grams per cubic centimeter and a mass of 0.78 Kilogram we proceed as follows;

Density=mass/volume
making volume the subject we get;
volume=mass/density
thus;
mass=0.78 kg= 780 g
density=2.375 g/cm^3
Hence,
volume=780/2.375=328.421 cm^3

Jim has some money ($n) in his pocket and his mum gives him $20. How much poney does he have now?​
liq [111]

Answer:

$n + $20

Step-by-step explanation:

Jim already has $n, and his mom has given him $20. We know we are not taking $n and subtracting $20, since his mom is adding that on to what he already has, we know we are not dividing, not multiplying but adding.

Conclusion : To find how much money he has now you would use the expression $n + $20

Hope this helps, please mark brainliest if possible. Have a nice day.
