Answer:
B. about 40 miles
Step-by-step explanation:
We need to find the miles traveled per hour. We can do this by taking the total number of miles traveled and divide it by the time it took to travel that distance. Converting 7 and 3/4 hours to decimals is 7.75 hours.
328.9 miles / 7.75 hours = 42.44 miles/hour
The closest answer is B, about 40 miles.

Answer:
Dissolve 190 grams of silver nitrate in 250 mL of water.
Step-by-step explanation:
First, find the moles of AgNO₃ from the volume and concentration.
0.250 L × 4.5 mol/L = 1.125 mol
Next, find the mass of AgNO₃ using the molar mass.
1.125 mol × 170 g/mol = 191.25 g
Rounded to two significant figures, dissolve 190 grams of silver nitrate in 250 mL of water.
14.603 rounded to the nearest whole number is 15.
Find the ones place (4). Look at the number next to the ones place. It is a 6. Because 6 is greater than 5, round up
15 is your answer

Answer: blank number 1 would be 4, and blank number 2 would be 8. then, blank number 3 would be 3. blank number 4 would be 2,048.
Explaination:
the starting number of employees is 4, so that starts off as our base number in the first blank. we are multiplying the 4 by how many will be there in 8 years, so that's why it goes in the second blank. now, we are tripling this every year, so that goes in the 3rd blank as the exponent. multiply all that together in a calculator, and you get 2,048.
