what are the new coordinates for (1,4) when rotated 180 degrees and 90 degrees counterclockwise, and 90 degrees clockwise?

1 answer:

7 0

90 degrees counterclockwise and 90 degrees cancel each other out. The coordinates of the point are only reflected over the x-axis. The point becomes (1, -4).

Hope I helped :)

12 ounces will be left in the bottle

Turn the 1/4 into a decimal which is 0.25 and times that by 20 and you’ll get 5, 5 is the amount of ounces you poured for your friend. Subtract 20 ounces by 5 ounces and you’ll get 15 ounces, then subtract 15 by 3 which is the amount of juice you poured for yourself and you’ll be left with 12 ounces in the bottle.

A ladder is leaning against the side of a building and positioned such that the base of the ladder is 17 ft from the base of the

andrezito [222]

Answer:

The ladder is 28.6 feet long.

Step-by-step explanation:

Given that:

Length of base = 17 feet

Length above the ground = 23 feet

These forms two legs of right angled triangle.

The length of ladder will be the hypotenuse.

Using Pythagorean theorem;

$a^2+b^2=c^2\\(17)^2 + (23)^2 = c^2 \\289 + 529 = c^2 \\c^2 = 818$

Taking square root on both sides

$\sqrt{c^2}=\sqrt{818}\\c=28.6$

Hence,

The ladder is 28.6 feet long.
