So if she got them at 30% off that means
$63 = 70%
divide both sides by 70 to get 1%
$0.90 = 1%
multiply by 100 to get full price
$90 = 100%
original price was $90
The polynomial remainder theorem allows us to calculate the remainder when a polynomial is divided by a linear polynomial:
The remainder of f(x) divided by (x-k) equals f(k).
Thus
f(x)=x^3+3x^2-10x-4 divided by x-3
gives a remainder of
f(3)=27+3(9)-10(3)-4=27+27-30-4=20
Therefore the remainder required is 20.
If the length is 3×width then length+width=4×width and the perimeter is 8×width=86, width=86/8=43/4=10.75cm.
The length is 3×10.75=32.25cm.
X = ( 10x + 2x)
That is saying he only refilled once
The height of the cylinder is 6 cm.
If the volume of the cylinder is 54π cm³, and we know the radius, we can use the formula for the volume of a cylinder to figure out the length of the height.
V = πr²h
Substitute
54π = 9h<span>π
</span>
Divide each side by <span>π
54 = 9h
Get h by itself
h = 6, which means that the height of the cylinder is 6 cm. </span>
