ANEK [815]
For the answer to the question above asking, w<span>hat was the price per can and the numbers of cans purchased each time?
let x be the number of cans he bought
the let us go to the 2nd statement which is t</span><span>he next time Ian purchased frozen orange juice, the price had increased by $0.10 per can and he bought 1 less can for the same total price.
The equation for this is .10(x-1) = 24
So now let's solve, 
</span> .10(x-1) = 24
.10x - .10 = 24
.10x = 24+ .10
.10x = 24.10
Then divide both sides by .10
So the answer for this question is

a scientist notes that the number of bacteria in a colony is 50.3, hours later she notes that the number of bacteria has increas
Yuri [45]

The time it would take for the bacteria to reach 1119 is 5.83 hours

<h3>Calculations and Parameters:</h3>

Given the function:

Pt= P_0e^k^t

  • Initial amount= 50
  • amount after 3 hours= 80

To find the exponential growth;

80 = 50e^k^*^3

k= 1.6/3\\k= 0.533

If there is a constant growth, then to get to 1119:

1119= 50e^0^.^5^3^3^*t

3.8 = 0.533*t

t= 5.83 hours

Therefore, it would take 5.83 hours for the bacteria to increase to 1119.

Find the measure of one exterior angle In each regular polygon​
AlekseyPX

Answer:

Step-by-step explanation:

The formula for exterior angles of a regular polygon is that they must add up to 360. They are also equal for a regular polygon.

Exterior angle = 360 / number of sides

The first one (a pentagon) has 5 sides

Exterior angle = 360/5

Exterior angle = 360/5 = 72

The second one has 8 sides.

Exterior angle = 360/8

Exterior angle = 360/8 = 45
