What is the LCM of 12,30 and 42
Hoochie [10]

Answer:

420

Step-by-step explanation:

We can find the prime factors of each of the numbers first before finding their LCM.

12: <em>2</em> × 2 × <u>3</u>

30: <em>2</em> × <u>3</u> × 5

42: <em>2</em> × <u>3</u> × 7

To find the LCM, we need to see if they are any common prime factors between all three numbers. The common prime factors are <em>2</em> and <u>3</u>. Then, we multiply 2 and 3 with the remaining outstanding factors, which are 2, 5, and 7.

LCM: <em>2</em> × 2 × <u>3</u> × 5 × 7 = 420

A letter L with a height of 9 inches is drawn on the actual flag. What should be the height and inches of a letter L in the scal
NISA [10]

Answer:

0.5 inch on the drawing

Step-by-step explanation:

The following information is missing:

<em>The scale factor of the drawing to the actual flag is represented by the ratio 1:18. </em>

This scale factor means that 1 inch on the drawing are equivalent to 18 inches o n the actual flag. We want to know the height on the drawing, given that a height of 9 inches is drawn on the actual flag. The following proportion must be satisfied:

1 inch on the drawing / x inch on the drawing = 18 inches o n the actual flag / 9 inches o n the actual flag

x = 9/18 = 0.5 inch on the drawing

In a square with side length of 6, what is the distance between the center of the square and the center of the largest equilater
Vanyuwa [196]
Place the right angle at the origin. Short leg on x-axis.
The forth corner of the square is the point on the hypotenuse where the line y = x intersects. (Draw a diagram!)
In this case the hypotenuse is y = -4x/3 + 8
x = -4x/3 + 8
7x/3 = 8
7x = 24
x = 3.428571429
