Answer:
78.9 grams.
Step-by-step explanation:
We have been given that Jackie Found a rock that has a mass of 78.852 grams. We are asked to find mass of the rock rounded to the nearest tenth.
We know that rounding to nearest tenth means rounding to one digit after decimal.
We can see that hundredths value in our given number is 5, so we will round up to nearest tenth as:
[tex]78.852\text{ grams}\approx 78.9\text{ grams}[/tex]
Therefore, the mass of the rock rounded to the nearest tenth would be 78.9 grams.
