Step-by-step explanation:

If we were using feet the expression would be 198x, where x is feet per second

During the worst periods of hyperinflation in a certain country, the price of food increased at a rate of 30% per month. State w
Serhud [2]

Answer:

It was an exponential increase

In 3 months, the bill will be $285.61

Step-by-step explanation:

First, this scenario is exponential, because the price of food is increasing with a percentage, based on the price that it was the previous amount.

Next, to find what the bill will be in 3 months, an equation needs to be made representing the situation.

Use the standard exponential equation: y = ab^x, where a is the initial amount, b is the growth rate, and x is the amount of time.

Plug in the values we know:

y = 130(1.3)^3

Solve for y

y = 285.61

So, 3 months later, the bill will be $285.61

The time spent to travel a certain distance varies inversely as a car's speed. If it takes 5½ hours to travel a certain distance
Licemer1 [7]

Answer:

6.6h

Step-by-step explanation:

  • So it takes 5.5 hours going at a speed of 60 miles per hour, multiply these two and we get a distance of 330 miles
  • Use this distance to find the time if speed is 50 miles per hour, so time is derived by dividing the distance by the speed
  • 330 miles divide by 50 miles per hour gives 6.6 hours
