$21.00
let the original price = 100%
then the discount price = 100 - 15 = 85%
divide $17.85 by 85 to obtain 1% then multiply by 100 to obtain original price.
original price = $17.85 × 
= $21
200 cm is 2 m so 40m/2m = 20. Thus she will have 20 pieces
No solution because the absolute value equals a negative number and it can only equal a positive number
V<span>=(</span><span>4/</span><span>3)</span><span>πr^</span><span>3
R=radius
Diameter= 2 times R
so,
R=7 ft
plugging the values;
V=(4/3)(3.14)(7)^3
V=1436.02 Cubic feet</span>
Well a circle has 360 degrees and this question wants the degree of counter-clockwise.
I think first we subtract 69 from 360, since that is the rotation clockwise, to get the angle of rotation.
360 - 69 is 291 degrees
