What is the approximate distance between the points (-3, -4) and (-8, 1) on a coordinate grid? A. 11.40 units B. 7.07 units C. 3
Blizzard [7]
The formula of the distance between two points:

A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\|AB|=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}

We have:

A(-3;-4);\ B(-8;\ 1)

substitute:

|AB|=\sqrt{(-8-(-3))^2+(1-(-4))^2}=\sqrt{(-8+3)^2+(1+4)^2}\\\\=\sqrt{(-5)^2+5^2}=\sqrt{25+25}=\sqrt{25\cdot2}=\sqrt{25}\cdot\sqrt2\\\\=\boxed{5\sqrt2\approx7.07}

Answer: B. 7.07

What 75% of two hundred
Ghella [55]

To find 75% of 200, we can multiply two fractions.

75/100 * 200/1

Now, just multiply the numerators and the denominators separately.

75 * 200 = 15000

100 * 1 = 100

Now, divide.

15000/100 = 150

<h3>75% of 200 is 150.</h3>
