Please give me an approximation of how long it would take to evacuate a population of 91,000 to a destination 21 miles away, usi
RoseWind [281]

Answer:

The time will depend on the number of people who move on each trip from the point of origin to the destination. If done at the maximum speed allowed using 100 vehicles of 50 seats each, the evacuation would be done in 63.68 hours

Step-by-step explanation:

Population = 91,000 ppl

Speed limit = 60 mph

Distance = 21 miles.

1. <em>Assuming that people is evacuated at the max. speed allowed, it means that each trip will take</em>:

T = D/V

D= 21 miles

V = 60 mph:

So;

T = 21 miles / 60mph

T= 0,35 h

2. Asumming that we are going to use an amount of 100 vehicles  with 50-seats in each trip for evacuating people, it means that we could evacuate

500 people every 0,35 h ≈ 1,429 ppl/hour <em>(evacuation rate)</em>

To know how long it would take us to evacuate 91,000 people under these conditions, we would have to divide the total amount by the previously calculated evacuation rate

T= 91,000/ 1,429 = 63,68 hours

For Jack's birthday, his mom is taking him and 12 friends to the zoo. If she pays $11 for each ticket using her credit card, wha
Gemiola [76]
Jack's mom is purchasing thirteen tickets at a price of $11 each. This equals a total of $143 in total spent. If Jack's mom has a credit card limit of $500, then after purchasing $143 with the card, her available amount to purchase additional things is $357. This impact on her available credit is due to credit cards working on an available balance system. When Jack's mom first received her credit card, a set balance or total amount she could purchase with the card was set. In this example, her total amount she could purchase with the card was $500. After her purchase of the tickets for $143 was completed, she subtracted that amount from her total available of $500 and that is why her available amount to purchase is now $357.

Answer:

Option C: 4

Step-by-step explanation:

<u>Use the Pythagorean Theorem:</u>

a^2+b^2=c^2

3^2+b^2=5^2

9+b^2=25

b^2=16

b=4

I NEED HELP!!! ASAP!!!!
Daniel [21]

I hope this helps you

at the 30-60-90 triangle has rules

30=>k

60=>k(square root of) 3

90=>2k

so in this triangle 60=> see 9

k(square root of) 3=9

k=9/(square root of) 3

2k=18/(square root of) 3

at the 45-45-90 triangle rules are

45=>2k

45=>2k

90=>[2k/(square root of 3)] (square root of) 2

x=[18/(square root of 3)].(square root of 2)

x=18(square root of 2)/square root of 3
