Question 1:
To find the density of milk, we use the formula:
\[ \text{Density} = \frac{\text{mass}}{\text{volume}} \]
From the table, the mass of milk is 5.15 g, and the volume is 5 cm³.
So,
\[ \text{Density of milk} = \frac{5.15 \text{ g}}{5 \text{ cm}^3} = 1.03 \text{ g/cm}^3 \]
The answer is: 1.03 g/cm³ (Note: You have mentioned "___9/m^2" but the correct density should be in g/cm³ for appropriate units.)
Question 2:
According to the formula provided:
\[ c = \frac{n - 40}{4} \]
Where \( n \) is the number of cricket chirps in 25 seconds. Charlie counted 51 chirps.
So we plug 51 into the equation:
\[ c = \frac{51 - 40}{4} = \frac{11}{4} = 2.75 \]
The temperature in degrees Celsius is: 2.75
Question 3:
Logan's work uses the formula for distance:
\[ d = rt \]
Where \( r \) is the rate and \( t \) is the time. However, Logan wrote:
\[ d = 70.05 \text{ miles} \]
He incorrectly wrote "70.05" instead of calculating using the given time of 0.05 hours.
To find the correct distance:
\[ d = r \times t = 70 \text{ mph} \times 0.05 \text{ hours} = 3.5 \text{ miles} \]
The issue is that Logan did not multiply the numbers correctly to find the distance.
So the correct answer is: Logan did not multiply the numbers.
