Answer: $14.93

Step-by-step explanation:

First, lets remove the shipping price: 51.65 - 3.50 = 48.15

Next, lets find the sales tax of the shirts: 48.15 x 0.07 = 3.37

Then, subtract that from the shirt price: 48.15 - 3.37 = 44.78

Finally, divide 44.78 by 3: 44.78 / 3 = 14.93!

Temka [501]

Great question! I had this question in Geometry on Edmentum.

Answer: Height of cone = 3y

Step-by-step explanation:

We know that the cylinder and the cone have the same volume. The cylinder has radius x and height y. We will make use of the formulas:

Volume of cylinder = πr²h

Volume of cone = 1/3πr²h

Since the cone has radius 1/3x, we will have to make its height 3 times of y (the height of the cylinder) to make both the cylinder and the cone have the same volume.

So, the height of the cone is equal to 3y.

Hope this helps, and have a wonderful day! :D

If y varies inversely with the square of x, and y=6 when x=4, find y when x=0.1
sergejj [24]

Answer:

9600

Step-by-step explanation:

y varies inversely with the square of x

y=k/(x^2)

for some non-zero constant k

y=6 when x=4

6=k/(4^2)

k=96

y=96/(x^2)

x=0.1

y=96/(0.1^2)

y=9600
