1. what’s the distance between (-8, -6) and (4, 10)?

charle [14.2K]

Use the formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$(-8,\ -6),\ (4,\ 10)\\\\d=\sqrt{(4-(-8))^2+(10-(-6))^2}=\sqrt{12^2+16^2}\\\\=\sqrt{144+256}=\sqrt{400}=\boxed{20}\\\\(5,\ 14),\ (-3,\ -9)\\\\d=\sqrt{(-3-5)^2+(-9-14)^2}=\sqrt{(-8)^2+(-23)^2}\\\\=\sqrt{64+529}=\boxed{\sqrt{593}\approx24.35}$

Answer:

3/8

Step-by-step explanation:

1- 1/4 +(1/2 x 3/4)

1. subtract 1/4 to get 3/4 (how much time she has left in class).

2. multiply 3/4 by 1/2 to find how much half of 3/4 is.

3. Half of 3/4 is 3/8 so that's how much time she spent on the balance beam.
