the population of bacteria in an experiment has been increasing by 50% each day. If there were 100 bacteria at the beginning of the experiment, predict the number of bacteria in 4 days

  506

Step-by-step explanation:

The count is multiplying by 1.5 each day, so after 4 days, it will have multiplied by 1.5^4 = 5.0625

Then the count is predicted to be ...

  100·5.0625 ≈ 506.25

The count will be 506 after 4 days.

i believe the answer is the polygon, heptagon.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
