Answer:

5.069\ cm

Step-by-step explanation:

we know that

The perimeter of the figure is equal to the circumference of a semicircle plus two times the length of 12 mm

Find the circumference of a semicircle

The circumference of a semicircle is equal to

C=\pi D/2

we have

D=1.7\ cm

substitute

C=(3.14)(1.7/2)=2.669\ cm

convert 12mm to cm

12\ mm=1.2\ cm

The perimeter of the figure is equal to

2.669\ cm+2*1.2\ cm=5.069\ cm

The vertices of a parallelogram are shown below.
OleMash [197]
The vertices for the dilated image can be found by multiplying the coordinates of the original image by the scale factor. In this problem, the scale factor is 1/3.

(0,0) ⇒ 0 x 1/3 = 0 ; 0 x 1/3 = 0 ⇒ (0,0)
(27,0) ⇒ 27 x 1/3 = 9 ; 0 x 1/3 = 0  ⇒ (9,0)
(36,30) ⇒36 x 1/3 = 12 ; 30 x 1/3 = 10 ⇒ (12,10)
(9,30) ⇒ 9 x 1/3 = 3 ; 30 x 1/3 = 10 ⇒ (3,10)

Answer is choice D. (3,10)

A triangle can be formed with side lengths 2 in, 3 in, and 6 in.
evablogger [386]
The two small sides of the triangle should add up and equal to the largest side.
2 + 3 = 5, 5 is smaller than 6, so the answer is NO because, at least there is a side that has the number close to each other, but if it is too far away, then 2 in can't reach to 6 in. to formed a triangle
So the answer is No
Hoped this will helped you!
If you don't believe me, draw the triangle on your paper and you'll see:)

One carpet cleaning cost are shown in the table. The relationship is linear. Find and interpret the rate of change and the initi
Ainat [17]
I see from the given data that each additional carpet after the first costs $50 each to have cleaned.

The first costs $125.  Supposing we subtract $50 from that, we get $75.  So, it sounds like it costs $75 just to get the carpet cleaners to your house.

The rule would then be $75 + $50x, where x : {1, 2, 3, 4, .... }

Let's check this result.  Suppose x = 1.  Will the charge be $125, as show in the table?  $75 + $50(1) = $125.  Correct.

Suppose x = 4.  Will the charge be $275 as shown in the table?
   $75 + $50(4) = $275.  YES
