So first, we're gonna split these into their own little sections.
If Duncan drove 30 mph for 20 minutes, we need to think about the time for now. One hour is 60 minutes, and 20 minutes is 1/3 of an hour. If it's 30 miles per hour, then we'd need to split that into thirds to give it the twenty minute value, so in twenty minutes he drove 10 miles.
For the second part, we're gonna do the same thing. 40 mph in twelve minutes. 60 divided by 12 is 5. Then split the 40 mph into fifths. 40 / 5 = 8. Every twelve minutes, he drove 8 miles.
Add 10 and 8, and he drove a total of 18 miles to get home.

The next model of a sports car will cost 5.9% more than the current model. The current model costs $33.000. How much will the price increase in dollars? What will be the price of the next model?
Answer:
Price increase $1,947
Price of the next model $34,947
Step-by-step explanation:
Since the next model of a sport car will cost 5.9% more than the current model, and the cost of current model is $33,000
The price increase in dollars would be;
= 5.9% × $33,000
= $1,947
The price of the next model would be;
= Cost of current model + Price increase
= $33,000 + $1,947
= $34,947

Karen bought a 40-pound bag of dog food at the beginning of the week. Her dogs ate f pounds of dog food during the week. Which expression can be used to find the amount of dog food that is left? 40 + f 40 - f F - 40 40/f
Answer:
40 - f
Step-by-step explanation:
Total pounds of food bought= 40 pounds
Total pounds of food eaten by the dog = f pounds
Total pounds of dog food left = Total pounds of food bought - Total pounds of food eaten by the dog
= 40 - f
Expression that can be used to find the amount of dog food that is left = 40 - f

The mean of 3.5,5.5,4.6,5.1,4.8,3.9,5.3 show work
Answer:
4.6714285
Step-by-step explanation:
Mean is calculated by adding all the numbers and dividing the total by how many numbers are there.
So, add all the numbers to recieve one total.
[tex]3.5 + 5.5 + 4.6 + 5.1 + 4.8 + 3.9 + 5.3 = 32.7\\\frac{32.7}{7} = 4.6714285[/tex]
Answer:
4.67143 or 4.67
Step-by-step explanation:
add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
3.5+5.5+4.6+5.1+4.8+3.9+5.3= 32.7
divide by the number of numbers
there are 7 number in total
32.7/7= 4.67143
