Answer:

6) x=9.75

10) Triangle OMN ~ Triangle ODK; SSS ~

11) SSS ~ theorem

12) SSS ~ theorem

Step-by-step explanation:

For #6, since the polygons are similar, then it must mean AD is congruent to JM and CD is congruent to LM. Now we can set up the proportion 39/20=x/5 and solve. Solving for x gets us x=9.75, so C is the correct choice

For #10, there's no information about angles whatsoever in the diagram, so B and C must be wrong. D must be wrong as well because if the triangles weren't similar, then why is OJ ~ JM and OK ~ KN? So thus, the triangles are similar by SSS.

For #11, this is sort of a no-brainer because there's no mention of angles, so D must be correct.

For #12, same concept, no mention of angles, all sides are similar to their respective sides of the different triangles, so A is correct.

Pedro wants to walk from the historic village to the science center. Then he will walk from the science center to the museum. If

MrRissso [65]

Answer:

5 hours

Step-by-step explanation:

Speed = 2 7/ 10 miles per hour

From the chart attached :

Distance between historic village and science center : (-4 1/2, 5 1/4) to (-4 1/2, -1 3/4)

Taking the sum of the absolute value of the y coordinate :

|5 1/4| + |-1 3/4| = 5 + 1 + 1/4 + 3/4 = 7

From science center to museum :

(-4 1/2, - 1 3/4) to (2, - 1 3/4)

Taking the sum of the absolute value of the x coordinate :

|4 1/2| + |2| = 4 + 2 + 1/2 = 6 1/2

Total distance traveled = 7 + 61/2 = 13 1/2 miles

Time taken = Distance / speed

Time taken = 13 1/2 ÷ 2 7/10

Time taken = 27/2 * 10/27

Time taken = 10/2

Time taken = 5 hours

What is the area of the composite shape

FrozenT [24]

Answer:

Step-by-step explanation:

The shape can be divided into two parts, let use the division in the question

So we have two rectangles

The area of a rectangle is given by l×b.

Let the big rectangle be 1

And the smaller rectangle be 2

Rectangle 1

Length is 16cm, breadth is 6cm

Area=l ×b

Area=16×6

Area=96cm^2

Rectangle two

The length will be 14-6=8cm

And the breadth will be 16-2=14cm

Then,

Area=l ×b

Area=14×8

Area=112cm^2

Total area is

Area1+Area2

112+96

Total area=208cm^2.

Divide the following polynomial using synthetic division, then place the answer in the proper location on the grid. Write answer

Alenkinab [10]

Answer:

The quotient is $x^2-3x+1$

Step-by-step explanation:

The given polynomial division is $(x^3-4x^2+4x-1)\div (x-1)$

To perform the synthetic division we write out the coefficients and arrange them as shown.

1 -4 4 -1

1 -3 1 0

The quotient is $x^2-3x+1$

The descending powers of x means from highest degree to the least

The remainder is 0
