y:  original price (in dollars)

0.12y:  amount of discount (in dollars)

sale price:  y - 0.12y = 0.88y

sales tax on this sale price:  (0.06)(0.88y)

final cost:  0.88y + (0.06)(0.88y) = 0.88y(1+0.06) =  0.9328y

A square garden plot has an area of 24 ft2.
strojnjashka [21]
The area of a square is equal to the side squared.
s^2=A

We can plug in 24 for A and then take the square root of each side to find s.
s^2=24 \\ s=\sqrt{24}

We can simplify √24.
The prime factorization of 24 is 2×2×2×3.
Since we have 2×2 inside the radical we can simplify to have 2 outside the radical.
\sqrt{24}=\sqrt{4\times6}=\boxed{2\sqrt{6}\ ft}

We can then use a calculator to find an approximate decimal value for 2√6.
(You could technically calculate it by hand using the Babylonian method, I don't think you're expected to do that, though)
2\sqrt{6}\approx\boxed{4.9\ ft}

a cone has a volume of 1230.88 units cubed and a diameter of 14 units what is the height of the cone use 3.14 for pi
ANEK [815]

Answer:

h= 24

Step-by-step explanation:

v = \pi {r}^{2}  \frac{h}{3}

r =  \frac{d}{2}

r =  \frac{14}{2}

r= 7

1230.88=3.14×7^2×h/3

1230.88= 153.86h/3

h=1230.88/153.86

h= 24
