Answer:
<h3>
2642km</h3>
Step-by-step explanation:
Given the map coordinates o a bird during travel from Vermont at cordinate (63,45) toto Venezuela at map coordinates (67,10). In order to know how far the bird has travelled, we need to find the distance between the two coordinates first using the formula;
D = ![\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
Given x₁ = 63, y₁ = 45, x₂ = 67, y₂ = 10
![D =\sqrt{(67-63)^2+(10-45)^2}\\ \\D = \sqrt{4^2+(-35)^2} \\\\D = \sqrt{16+1225} \\\\D = \sqrt{1241} \\\\D = 35.2278](https://tex.z-dn.net/?f=D%20%3D%5Csqrt%7B%2867-63%29%5E2%2B%2810-45%29%5E2%7D%5C%5C%20%5C%5CD%20%3D%20%5Csqrt%7B4%5E2%2B%28-35%29%5E2%7D%20%5C%5C%5C%5CD%20%3D%20%5Csqrt%7B16%2B1225%7D%20%5C%5C%5C%5CD%20%3D%20%5Csqrt%7B1241%7D%20%5C%5C%5C%5CD%20%3D%2035.2278)
If each map coordinate represents 75 kilometers, then the birds distance in km will be 75*35.2278 = 2642.087km
Hence the birds distance in km will be 2642km to the nearest kilometers

Answer:
x = sqrt 2, y = 2
Step-by-step explanation:
45-45-90 triangles have a ratio of 1 : 1 : sqrt2

Answer: D. 72</h3>
Work Shown:
Angle PQR = (far arc - near arc)/2
Angle PQR = ( (major arc PR) - (minor arc PR) )/2
Angle PQR = ( (2x+252) - (2x+108) )/2
Angle PQR = 144/2
Angle PQR = 72
Notice how we didn't need to find the value of x at all.
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
![3+4(16-9)](https://tex.z-dn.net/?f=3%2B4%2816-9%29)
We first solve the brackets:
(16-9) = 7
Now, we multiply it with 4
![7\times 4=28](https://tex.z-dn.net/?f=7%5Ctimes%204%3D28)
Now, we add 3 to it:
![28+3=31](https://tex.z-dn.net/?f=28%2B3%3D31)
Hence, the value of expression would be 31.
Therefore, First option is correct.
