Y = 10logx

"The sound intensity of rustling leaves is 100 times the reference intensity."
but x = ratio of intensity of sound to reference to intensity, so the x = 100:1 or x = 100

y = 10log(100) = 10 * 2 = 20 decibels


20 decibels

X=100
Y=10log100
Log100= 2
2x10=20
Y=20 decibels

You read 50 pages in an hour your sister reads 40 pages in an hour how many more pages did you read than your sister reads in 1/

Elena-2011 [213]

To start to figure this problem out, we can first figure out how many more pages you read in an hour compared to your sister.

50 - 40 = 10, so you read 10 more pages in 1 hour.

Now we have to figure out how much more you would read in 1/2 an hour. Since 1/2 an hour is 1/2 of an hour, we can divide 10 by 2 to figure out how many more pages you read in an hour compared to your sister. 10 divided by 2 is 5, so you read 5 more pages every half hour.

(picture) Factoring Polynomials: GCF PLEASEE HELP!!!!! a b c d

tigry1 [53]

Answer:

greatest common factor is 2

Step-by-step explanation:

4k, 18k^4, 12

To find greatest common factor , we write each term in factor form

factors form are the product of the factor of given term

4k ---> 2 * 2* k

18k^2 ----> 3 * 3* 2* k*k

12 -----> 2*2*3

all the three terms has common factor 2

So GCf is 2

Triangle A C B is cut by line segment E D. Line segment E D goes from side B C to side A C. The length of B A is 4 x minus 6 and

bezimeni [28]

From the markings on the diagram, we can tell E is the midpoint of BC and D is the midpoint of AC. We can apply the triangle midsegment theorem: ED = ½BA. Substituting in the expressions for the lengths and solving for x, we get x = 5. Now, since BE = x, then BC = 10.

<h3>What is triangle midpoint theorem?</h3>

Triangle midpoint theorem states that the line segment which joins the midpoints of two (2) sides of a triangle is parallel to the third side, and it's congruent to one-half of the third side.

By applying the triangle midpoint theorem, we can find the value of x:

ED = ½BA

x + 2 = ½(4x - 6)

2x + 4 = 4x - 6

4x - 2x = 6 + 4

2x = 10

x = 10/2

x = 5.

BC = x + x

BC = 5 + 5

BC = 10.
