Answer:
$15 and 50 cents
Step-by-step explanation:
3.25x2=6.50+9=15.50
Start with the standard form of a circle, where is the center of the circle and is the radius.
Plug in the known values.
This is the circle's equation in standard form.
0.15 x 10^3 just means that you will move 3 decimal places to the right.
So we get 150
Here's how to do dividing in a certain ratio:
-- You want to divide up the whole thing in the ratio of
4 parts, 5 parts, and 9 parts.
-- How many parts all together ? (4 + 5 + 9) = 18 parts all together.
-- The whole thing is 180, and that's 18 total parts.
So each part is (180/18) = 10 degrees.
4 parts = (4 x 10) = 40
5 parts = (5 x 10) = 50
9 parts = (9 x 10) = 90.
Check: (40 + 50 + 90) = 180 . yay!

For the second one, I think there are some words missing.
