Atransportation expert measures the amount of traffic on a certain road by recording the number of cars that pass a point on the road every 5 minutes. he starts setting up his equipment shortly before 8 am and manually counts the cars until he gets the electronic monitoring system in place. by exactly 8 am, he has manually counted 43 cars and he starts his equipment. if the electronic equipment records exactly 18 cars passing it every 5 minutes, find a formula to calculate the total amount of cars that have passed that point on the road since the expert started setting up his equipment, at five minute intervals, starting at 8 am. use this formula to figure out what time of day the 871st car will pass by the monitoring system.

step-by-step explanation:

a negative exponent is translated as follows:

so, we have

she will travel a distance in the range of 3 - 11 miles

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
