1+4=5, 2+5=12, 3+6=21, 8+11?

Answers

Answer 1
Answer: The answer is 96.
Solution:
1+4(5) = 5
2+5(7) = 12(5+7)
3+6(9) = 21(12+9)
4+7(11) = 32(21+11)
5+8(13) = 45(32+13)
6+9(15) = 60(45+15)
7+10(17) = 77(60+17)
8+11(19) = 96(77+19).

Determine the area of the regular hexagon

Answers

Answer:To determine the area of a regular hexagon, we need to use the formula:

Area = (3√3 * s^2) / 2

Where:

- s represents the length of one side of the hexagon.

In the given question, the side length of the regular hexagon is not provided. Therefore, we cannot calculate the exact area without that information.

However, if we assume the side length is 7.79 meters, we can substitute it into the formula to find the area:

Area = (3√3 * (7.79)^2) / 2

Area = (3√3 * 60.6641) / 2

Area ≈ 104.434 square meters (rounded to three decimal places).

Again, please note that this answer assumes the side length of the hexagon is 7.79 meters. If the actual side length is different, the area will also be different.

What is the answer to 4(x + -7) +12=20

Answers

    4(x - 7) + 12 = 20
4(x) - 4(7) + 12 = 20
     4x - 28 + 12 = 20
             4x - 16 = 20
                 + 16 + 16
                     4x = 36
                      4      4
                       x = 9
X=9You ise the distribution property and get 4x-28+12=20. Combine the like terms amd you get 4x -16=20. Add 166 to both sides and you get 4x =36. Divide by four and you get x=9

How do you find the volume inside the cylinder but outside the sphere? H=12cm.

Answers

Apparently, there is a sphere inside a cylinder, and we need to find
(the volume of the cylinder) minus (the volume of the sphere).

This wouldn't be too awfully difficult if we had the measurements we need
in order to calculate the volume of the cylinder and the volume of the sphere. 
You did give us a number, thank you, but no description, so we don't even know
what's 12, because we don't know how 'H' figures into anything.

If you have the numbers, here are the formulas you'll need:

Volume of a cylinder = π (radius)² (height or length)

Volume of a sphere = (4/3) π (radius)³
===============================================
Oh I think I get it.  There's a little ball stuck inside a cylinder, they
both have the same radius, and the height of the cylinder is 12.

That's still not enough information to do a complete calculation.
I'm afraid we still need that radius.  But we can get closer:

Volume of the cylinder = π (radius)² (12)

Volume of the sphere = (4/3) π (radius)³

(Cylinder) minus (sphere) = (4/3) π (radius²) ( 9 - radius ) .

Stuff the number for the radius into that, and you'll have the answer.

And if you need it, remember, the radius is 1/2 of the diameter.

. A recipe calls for 3 teaspoons of salt for every 5 cups of flour. If you wanted to make a larger batch with 15 cups of flour, how much salt would you need? A. 5 teaspoons B. 10 teaspoons C. 9 teaspoons D. 6 teaspoons

Answers

Given:
3 teaspoons of salt for every 5 cups of flour.

How much salt is needed for 15 cups of flour?

This is a proportion problem:
a/b = c/d where ad = bc

3/5 = x/15
3*15 = 5x
45 = 5x
45/5 = x
9 = x

C. 9 teaspoons of salt is needed for 15 cups of flour.

3/5 = 9/15
3*15 = 5*9
45 = 45
