Step-by-step explanation:

Simplify 15 − 10 x 8 x 3 − 12 x 2 \dfrac{15- 10x}{8x^3-12x^2} 8x3−12x215−10xstart fraction, 15, minus, 10, x, divided by, 8,

Gotcha, bro.

(I don't know what pi is, so I'm gonna assume that it is 3.14)

C=pi x diameter

First, multiply the radius by 2 so you have the diameter.

3x2=6

Second, multiply 3.14 (pi) by 6 (diameter)

3.14x6=18.84

Therefore, the circumference is 18.84.

(19 if you round it to the whole number)

Hope this helps!

(btw if pi is something else, use these steps to help you out)

The circumference of the circle is 6π meters.

A circle is a two dimensional figure with a radius and circumference of 2πr.

We have,

The circumference of a circle is given by the formula:

C = 2πr

where r is the circle's radius and π (pi) is a mathematical constant approximately equal to 3.14.

In this case, the radius of the circle is 3 meters.

Substituting this value in the formula, we get:

C = 2πr

C = 2π(3)

C = 6π

Therefore,

The circumference of the circle is 6π meters.

Answer:

22

Step-by-step explanation:

The result of 154 divided by 7 will be 22.

The rules of the division include easy memory tricks that make division calculations easier by generating patterns you may use to deconstruct both simple and complex situations. The guidelines establish requirements that a number must meet in order to neatly divide into another number. While some division rules only require one or two steps to evaluate a number's divisibility, others require two or three steps. Even though some of these formulas are lengthy, division rules help hasten the process of dividing huge numbers.

Remember to continue using the divide, multiply, subtract, and drop-down method for long division problems until all of the dividend's digits have been divided. The solution to the division puzzle is the quotient.

Since the given problem is not a large division. We can solve it by breaking 154 into two parts

    ______

7 / 154     \    2 2

   14

 ---------

   1 4

    0

Therefore, 22 will come from dividing 154 by 7.

Step-by-step explanation:

The author's message is that a person cannot predict the future without first learning about the past. The author does this by providing an example of how one wants to read without knowing the letters of the alphabet. Obviously, you can't read without first learning the letters of the alphabet. With the reading example, the author is explaining that just like a person trying to read without learning the alphabet first, a person predicting the future without knowing their history first is doing the exact same thing, it's nearly impossible.

Answer:

x > 1

Step-by-step explanation:

Subtract 3 from both sides

8x + 3 - 3 > x + 10 - 3

Simplify

8x > x + 7

Subtract x from both sides

8x - x > x + 7 - x

Simplify

7x - 7

Divide both sides by 7

7x/7 > 7/7

Simplify

x > 1

Answer:

18.6%

Step-by-step explanation:

What is the percentage population increase if in 2001 it is 430000 and in 2011 it is 510000

Percentage increase is calculated as:

Final value - Initial value/ Initial value × 100

Final value = 510000

Initial value = 430000

Percentage Increase =

510000 - 430000/430000 × 100

= 80000 / 430000 × 100

= 0.1860465116 × 100

= 18.604651163 %

Approximately = 18.6 %

Answer:

10

Step-by-step explanation:

You make a proportion 9/6=15/x then multiply 6 and 15 and divide it by 9

The height the 15 ft building touches the building is approximately 10 ft.

The ladder is 9 ft tall and leaning on a wall that is 6 ft above the ground.

The situation forms a right angle triangle.

Therefore, let's find the angle made by the 9 ft ladder and then use it to find the height the 15 ft ladder touch the building.

Using trigonometric ratios,

let

∅ = angle

tan ∅ = opposite / adjacent

tan ∅ = 6 / 9 = 2 / 3

∅ = tan⁻¹ 0.6666666

∅ = 33.6900672615

Therefore, the height the 15 ft ladder touch building can be calculated as follows:

tan 33.69 = h / 15

h = 15 × 0.66666496431

h = 9.99997446476

h ≈ 10 ft.
