To find "s", you can use the Pythagorean theorem(which you can only use for right triangles):

a² + b² = c² (c is the hypotenuse/the longest side of the triangle)

t = 18 (hypotenuse)

r = 12

s = ?

Plug in the numbers into the equation

a² + b² = c²

(12)² + b² = (18)²

144 + b² = 324 Subtract 144 on both sides

b² = 180 Square root both sides

b = √180 or 13.4

What is the distance between point A(-3,2) and point B(5,-1)

Gnoma [55]

Remember the distance formula

$S=\sqrt{(5+3)^{2}+(-1-2)^{2} }$

$S=\sqrt{8^{2}+(-3)^{2} }$

$S=\sqrt{64+9}$

$S=\sqrt{73}$

Yasmine bought 6 gallons of apple juice. After filling up 4 bottles of the same size with apple juice, she had 0.3 gallon of app

never [62]

1.425 gallons of apple juice are in one container

I got this because if she starts with 6 gallons and she’s left with 0.3 gallons, you would need to subtract 6 by 0.3 (6-0.3=5.7). So now you know how much is in 4 bottles. Now you need divide 5.7 by 4 to find out how much is in each container (which is 1.425).
