Which of the following triangles are impossible to draw? Choose all that apply.

Mathematics
1 answer:
ioda3 years ago
7 0
I would say a triangle with two right angles because a triangle's angles add to 180 degrees. If a triangle has two right angles, it means that two angles will be 90 degrees, which add to 180 degrees. A triangle must have three angles and sides, and it is not possible for the last angle to be 0 degrees.

Hope this helps

Q3.) Write the standard form of the equation of the circle with the given center and radius.
vlada-n [284]
The center has coordinates h = -2, k = 5.  The radius is sqrt(6).  The equation for a circle is as follows: (x-h)^2+(y-k)^2=r^2.  Filling in using our given info we have (x-(-2))^2+(y-5)^2=( \sqrt{6})^2.  Simplifying that down we have an equation of (x+2)^2+(y-5)^2=6.  There you go!

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
