You can buy DVDs at a local store for $15.49 each. You can buy them at an online store for $13.99 each plus $6 for shippimg. How

NeTakaya

15.49x = 13.99x + 6
15.49x - 13.99x = 6
1.50x = 6
x = 6 / 1.50
x = 4 <=== u can buy 4 DVD's for the same amount

15.49 * 4 = 61.96
13.99(4) + 6 = 61.96

V=1/3Πr^2(2r+h)

stiv31 [10]

Answer:

h= $\frac{−2.094395r3+v}{1.047198r2}$

Step-by-step explanation:

v=( $\frac{1}{3}$ (3.141593))(r2)(2r+h)

Step 1: Flip the equation.

1.047198hr2+2.094395r3=v

Step 2: Add -2.094395r^3 to both sides.

1.047198hr2=−2.094395r3+v

Step 3: Divide both sides by 1.047198r^2.

h= $\frac{−2.094395r3+v}{1.047198r2}$
