Answer:
The original number is 28
Step-by-step explanation:
start by listing all possible combinations of digits that give 10 when added:
19 (1+9=10)
28 (2+8 =10)
37 (3+7=10)
46 (4+6=10)
55 (5+5=10)
Look into the order of digits reversed and what the difference with the original number gives:
1) 19 reversed is 91 then when we subtract 91 - 19 we obtain 72
2) 28 reversed is 82 hen when we subtract 82 - 28 we obtain 54 which is the combination we where trying to find.
Notice as well, that as we go down the list, the differences between reversed digit number and original become smaller (and ends being zero for the number 55), so they do not satisfy the requirement.
Therefore 28 is the answer, since 82 (the new number formed when the digits are reversed) exceeds the original number by 54.
Answer:
D,
Step-by-step explanation:
the volume of a sphere is 4/3πr^3
Ths solubility curve is used to show the amount of salt dissolved (solubility).
<h3>What is the solubility curve?</h3>
The solubility curve is a depiction of the solubility of a substance plotted against its temperature. It can be used most times to show the solubility of a susbtance at different temperatures. This question is incomplete hence so we can not be able to obtain the solubility of the salt at this temperature.
If the solubility curve has been shown in the graph, then we can be able to obtain the solubility of the salt from the data shown on the plot.

I think it’s 120. Hope this helps
