The formula of a distance between two points:
![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)
We have the points (-1, 8) and (5, -2). Substitute:
![d=\sqrt{(5-(-1))^2+(-2-8)^2}=\sqrt{6^2+(-10)^2}=\sqrt{36+100}=\sqrt{136}\\\\=\sqrt{4\cdot34}=\sqrt4\cdot\sqrt{34}=\boxed{2\sqrt{34}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%285-%28-1%29%29%5E2%2B%28-2-8%29%5E2%7D%3D%5Csqrt%7B6%5E2%2B%28-10%29%5E2%7D%3D%5Csqrt%7B36%2B100%7D%3D%5Csqrt%7B136%7D%5C%5C%5C%5C%3D%5Csqrt%7B4%5Ccdot34%7D%3D%5Csqrt4%5Ccdot%5Csqrt%7B34%7D%3D%5Cboxed%7B2%5Csqrt%7B34%7D%7D)
Answer:
Mind stating the question a bit more clear? I can barely tell, ill edit this once you do.
Step-by-step explanation:
Answer:
60
Step-by-step explanation:
Has 16 cups of water that is half full.
16/2 = 8
Watering can then has 8 cups of water in it.
This number needs to be divided by 15 plants.
The answer is 8/15 of a cup of water per plant which is also 0.53 cups per plant.

Answer:
c) 1.8 miles
Step-by-step explanation:
Assuming Kayla walks at a constant speed, we have ...
miles/minutes = 3.2/45 = x/25
x = 25(3.2/45) = 1.777... ≈ 1.8 . . . . miles
Kayla walks about 1.8 miles in 25 minutes.
