Answer:
13 unit
Step-by-step explanation:
By the distance formula,
The distance between two points
and
is,
![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
Thus, the distance between B(8,-7) and C(-4,-2) is,
![BC=\sqrt{(-4-8)^2+(-2+7)^2}](https://tex.z-dn.net/?f=BC%3D%5Csqrt%7B%28-4-8%29%5E2%2B%28-2%2B7%29%5E2%7D)
![=\sqrt{(-12)^2+(5)^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%28-12%29%5E2%2B%285%29%5E2%7D)
![=\sqrt{144+25}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B144%2B25%7D)
![=\sqrt{169}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B169%7D)
![=13\text{ unit}](https://tex.z-dn.net/?f=%3D13%5Ctext%7B%20unit%7D)
Answer:
145
Step-by-step explanation:
725 divided by 5 is 145
44 you should subtract 80 and 36 then the answer will be 44
Conner played a total of 6 +3 + 6 = 15 games. He won or tied 6+ 3 = 9 games.
His percentage is 9/15 = 0.6 x 100 = 60%
April played 5+7+4 = 16 games and won or tied 5 +7 = 12 games.
Her percentage is: 12/16 = 0.75 x 100 = 75%
Tony played 20 games and won or tied 14.
His percentage is: 14/20 = 0.7 x 100 = 70%
April has the highest percentage so she is the one who should play.
