What is the value of x?<br><br><br><br><br><br><br><br> Enter your answer as a decimal in the box.
Alexandra [31]

<u>Answer</u>:

x = 22.5

<u>Explanation</u>:

Given Sides:

  • HB = 6
  • HD = 6+15 = 21
  • HM = 9
  • HT = 9 + x

-----------------------------

using all these sides, create similarities equation:

\frac{HB}{HD}  = \frac{HM}{HT}

\frac{6}{21}  = \frac{9}{9+x}

6(9+x) = 9(21)

54 + 6x = 189

6x = 189 - 54

6x = 135

x = \frac{135}{6}

x = 22.5

Two similar polygons are shown below: A coordinate grid is shown from positive 10 to negative 10 on the x-axis and from positive
defon

Answer:

Dilation factor of 3

Step-by-step explanation:

First you wil want to find out the the coordinates for each of the shapes:

Regular:

P =9,6

Q =3,6

R =6,3

S =3,3

Prime notation:

P' =3,2

Q' =1,2

R' =2,1

S' =1,1

Then using great old common sense in the picture you will see 3 units go down to 1 unit which will indicate Dilation factor of 3 as the answer!

Hope this helps!

Use the following chart of years and prices to answer the following questions.
Alenkasestr [34]

Answer:

A) What was the absolute change from 1970 to 1990?

in 1970 we had $87.32

in 1990 we had $283.16

The absolute change is the direct difference:

$283.16 - $87.32 = $195.84

B) What was the relative change from 1970 to 1990?

Now we need to compare this with the initial value:

Relative change = 100%*(final value - initial value)/initial value.

Relative change = 100%*$195.84/$87.32 = 223.93%

C) What was the absolute change from 1995 to 2000?

in 1995 the price was $351.94

in 2000 the price was $349.69

The absolute change is:

$349.69 - $351.94 = -$2.25

The negative sign means the obvious thing, the price decreased.

D) What was the relative change from 1995 to 2000?

Relative change = 100%*(-$2.25)/($351.94) = -0.64%

What is the probability that a point chosen at random in the regular hexagon lies in the shaded region? A 1/3 B 2/5 C 1/2 D 2/3
kondaur [170]
Answer: option A) 1/3

Justification:

1) The probability that a point chosen at random <span>in the regular hexagon lies in the shaded region is equal to:

  area of the shaded region
---------------------------------------
     area of the hexagon

2) The hexagon is formed by 6 equal triangles and the shaded area is formed by 2 of those triangles.

3) Therefor,naming x the area of one triangle, the the above fraction is equal to:

  area of two triangles           2x        
------------------------------- =    --------   = 2/6 = 1/3
  area of six triangles            6x

And that is the answer: 1/3
