if you have 6 cars, 10 trucks, 14 suv, 15 minivan, at this rate how many trucks would pass luann if 90 vehicles passed her. show your work
There would be 20 trucks.
6 + 10 + 14 + 15 = 45
6 + 10 + 14 + 15 = 45
45 + 45 = 90
I basically doubles the amount, but in this case, the different vehicles pass Luann twice in a row. So, 20 trucks passed her.
I hope this helps! :)
20
To figure out how many trucks would pass Luann if 90 vehicles passed her, we need to find the proportion of trucks compared to the total number of vehicles. Here's how to calculate it:
1. Find the total number of vehicles: 6 cars + 10 trucks + 14 SUVs + 15 minivans = 45 vehicles.
2. Calculate the proportion of trucks: (10 trucks / 45 total vehicles) * 100 (to express it as a percentage) = 22.22% (rounded to two decimal places).
3. Find how many trucks would pass Luann out of the 90 vehicles: (22.22% * 90 vehicles) / 100 (to convert it back from a percentage to a count) = 19.998 trucks.
Since we can't have a fraction of a truck, we'll round the answer to the nearest whole number. Therefore, approximately 20 trucks would pass Luann if 90 vehicles passed her.
