Answer:

The LCD is 18.

Step-by-step explanation:

2 = 2

6 = 2*3

9 = 3 * 3

The Least Common  Multiple =    2 * 3* 3 = 18  (because there is 1 pairs of 2's and 1 pair of 3's in the factors, so only 1 of each appear in the calculation).

Julio says if you subtract 17 from my number and multiply the difference by - 2 the result is gonna be negative 12 what was Juli
Paha777 [63]

Answer:

23

Step-by-step explanation:

Taking an algebraic approach

let the number be n, then (n - 17) is 17 subtracted from number and

- 2(n - 17) = - 12 ( divide both sides by - 2 )

n - 17 = 6 ( add 17 to both sides )

n = 23

Thus Julio's number was 23

Find the area of the shaded region
Dimas [21]

The area of the shaded region is 15.453 square units.

Step-by-step explanation:

Step 1:

The given shape consists of a rectangle and two circles.

The length of the rectangle is given as 12 cm. Both the diameters of the circles equal 12 cm. So each circle has a diameter of 6 cm and thus a radius of 3 cm.

The diameter of the circle is equal to the width of the rectangle.

So the rectangle has a length of 12 cm and a width of 6 cm. The circles have radii of 3 cm each.

Step 2:

The area of the rectangle = (l)(w) = (12)(6) = 72 square cm.

The area of each circle = \pi r^{2}  = (3.1415)(3^{2} ) = 28.2735 square cm.

The area of both circles =2(28.2735) = 56.547 square cm.

The area of the shaded region is the difference between the area of the rectangle and the area of both circles.

The area of the shaded region = 72 - 56.547 = 15.453 square units.

The area of the shaded region is 15.453 square units.

24.012 divided by 6 steps
Marina CMI [18]
4.002.

The steps for this are as follows:

Set up the equation, 24.012 divided by 6.

Six cannot go into 2, so the first number is going to be zero. Drop down the 4 to make the number 24, and divide by 4. This makes the second number 4.

Next you have to make sure you place the decimal up to the final answer and bring down the zero. Since six can’t be divided into zero, the next number above is 0. Bring down the one, again can’t be divided so put a zero. Then bring down the two to make the number twelve and bring up the two.

Here’s a visual for better clearance:

Hope this helps!
