Answer:

If we say the circumference is 1600 pi, and this is equal to pi times the diameter, we can just divide both sides by pi to get the diameter, which is going to be 1600.

Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).

Gabe is planning on riding the roller coaster 25 times. If he has already ridden 36% of his 25 times, how many times has Gabe al
AVprozaik [17]
If you do 25 x X = 100
It would be x = 4
So we would divide 36% by 4 to get how many times he rode, which is 9
So he already has ridden 9 times.

Can somone help me pls
Nastasia [14]

Answer:

x = 9

Step-by-step explanation:

First equation = 4x - 8

Second equation = 7x - 35

Seperate the equation with an equal sign to make it an equality equation and solve for X so :

4x - 8 = 7x - 35 (Given)

-3x - 8 = -35 (Subtraction property of equality)

-3x = -27 (Addition property of equality)

x = 9 (Division property of equality)

Solution:

x = 9

A scientist determines that the number of bacteria in a culture is modeled by the formula A(t)=4,000e0.02t, where t is the numbe
SpyIntel [72]

Using the exponential model given, the number of bacteria in the culture after 9 minutes after the observation began will be 4789

<u>Given the exponential model</u> :

  • A(t) = 4000e^{0.02t}
  • A(t) = Number\:bacteria\:in\:the\:culture\:after\:t\:minutes
  • <em>t = number of minutes after observation begins </em>

<u>The number of bacteria in the culture 9 minutes after the observation began can be calculated thus :</u>

t = 9 \: minutes

<em>Substitute 9 for t in the exponential equation :</em>

A(t) = 4000e^{0.02\times9}

A(t) = 4000e^{0.18}

A(t) = 4000 \times 1.1972173

A(t) = 4788.87

Therefore, the number of bacteria in the culture after 9 minutes will be about 4789
