stiks02 [169]

Answer:

<em>184,499 will fit, Yes</em>

Step-by-step explanation:

<u>Proportions</u>

We'll use proportions to answer the question and find the number of students fit into a building of 300 ft x 300 ft. The area of the building is

300\ in\times 300\ in=90000\ in^2

We are given a factor of 2.05 students per square feet, thus the number of students that fit into the building is

2.05\cdot 90000\ in^2=184500

Since 184500 is greater than 142551 people required, they easily fit into that space.

The closest answer is

184,499 will fit, Yes

Answer: 65.1 (mg)

Step-by-step explanation:

y=190*e^{-a*t}\\\\Calculate\ a:\\\\t=33,y=95(mg)\\\\190*e^{-a*33}=95\\\\e^{-a*33}=0.5\\\\-a*33=ln(0.5)\\\\a=\dfrac{ln(\dfrac{1}{2}) }{-33} \\\\a=0,02100... \approx{0.021}\\\\If\ t=51\ h, y=190*e^{-0.02100*51}=65.09167...\approx{65.1}
