Answer:

A. 15 You are correct.

Step-by-step explanation:

The formula used to find the hypotenuse in this problem is called the Pythagorean Theorum.  The formula is as follows:  a^2 + b^2 = c^2.  Or, you can say that the hypotenuse is equal to: c = the square root of a squared and b squared  added together.  This might sound confusing in the start, but here's all you have to do.  a = 9, and b = 12.  9 squared is 81.  12 squared is 144.  144 + 81 = 225.  The square root of 225 is 15, because 15 x 15 = 225.  So 15 is your answer.

Answer:

A. 15

Step-by-step explanation:

Ooh, look! This triangle is a Pythagorean triple! Without even needing to use a formula, I can tell that you are correct and the answer is A. 15.

It's based off of a 3-4-5 right triangle, because 9-12-15 simplifies to that if you divide every term by 3. It's basically just a bigger version of a 3-4-5 triangle! Isn't math cool:)

Solve the equation 4*e+2=1 (mod5)
otez555 [7]

Here's a way to do it.

Let 4e +2 = 5n +1 . . . . . . for some integer n

Then e = (5n -1)/4 = n + (n -1)/4

We want (n-1)/4 to be an integer, so let it be integer m.

... m = (n -1)/4

... 4m = n -1

... 4m +1 = n

Substituting this into our expression for e gives

... e = (5(4m+1) -1)/4 = (20m +4)/4 = 5m +1

e = 5m+1 for any integer m

melanie made a circular necklace she puts beads evenly spaced around the necklace if the 4th bead is directly across from the 11
dangina [55]

Answer:

Step-by-step explanation:

If the 4th lies opposite the 11th, then you know the 3rd lies opposite the 10th, the 2nd opposite the 9th, and the 1st opposite the 8th; meanwhile, in the reverse direction you'd find that the 5th lies opposite the 12th, the 6th opposite the 13th, and the 7th opposite the 14th. Move up one more bead and you're back at the 1st, which you already know lies opposite the 8th. Therefore there are 14 total bead

Answer:

Step-by-step explanation:

Volume of cylinder:

\boxed{\text{Volume of cylinder=$\pi r^{2}h$}}

<u>Bottom cylinder:</u>

1 inch = 2.54 cm

 diameter = 14 in

r = 14/2 = 7 in

r = 7 *2.54 = 17.78 cm

h = 4 in = 4*2.54 = 10.16 cm

Volume = 3* 17.78 * 17.78 * 10.16

             = 9635.59 in³

<u>Upper cylinder:</u>

diameter = 12 in

r = 12/2 = 6in

r = 6*2.54 = 15.24 cm

h = 12 in = 12*2.54 = 30.48 cm

Volume = 3 * 15.24 *15.24 * 30.48

             = 21237.63 in³

Volume of the object = 9635.59 + 21237.63                  

                                     = 30873 cm³
