Draw the image of \triangle ABC△ABCtriangle, A, B, C under a dilation whose center is PPP and scale factor is \dfrac{1}{3} 3 1 ​
zavuch27 [327]

Dilating the triangle ABC would create another triangle whose size is different from the triangle ABC

<h3>How to dilate the triangle?</h3>

From the complete question, we have the following coordinates:

  • Point A = (-4,5)
  • Point B = (7,-7)
  • Point C = (-2,2)
  • Point P = (1,-4)
  • Scale factor, k = 1/3

The dilation rule across the center P is:

(x, y) --> (1/3x – 1, 1/3y + 4)

So, the coordinates of the image of the triangle are:

A' =  (-1/3 * 4 – 1, 1/3 * 5 + 4)

A' =  (-7/3, 17/3)

B' =  (1/3 * 7 – 1, -1/3 * 7 + 4)

B' =  (4/3, 5/3)

C' =  (-1/3 * 2 – 1, 1/3 * 2 + 4)

C' =  (-5/3, 14/3)

From the above computation, the coordinates of the new triangle is:

A' =  (-7/3, 17/3)

B' =  (4/3, 5/3)

C' =  (-5/3, 14/3)

See attachment for the image of triangle ABC

Two diced are rolled. What is the probability that the sum of two numbers on the dice will be 4? 11/121/40
makkiz [27]

Each die has 6 possible outcomes (the numbers from 1 to 6).

If we roll two dices, the total number of outcomes is 6 * 6 = 36.

From these outcomes, the ones that have a sum of 4 are:

(1, 3), (2, 2) and (3, 1).

So, if we have 3 wanted outcomes from a total of 36, the probability is:

P=\frac{3}{36}=\frac{1}{12}

Therefore the correct option is the second one.

Help!! 20 points and brainly!!
sergejj [24]

Answer:

26

Step-by-step explanation:

Let x be the first even integer

x+2 is the second even integer

x+4  is the third even integer

The sum of three consecutive even integers is 84

x+ (x+2) + (x+4) =84

Combine like terms

3x +6 = 84

Subtract 6 from each side

3x+6-6 =84-6

3x =78

Divide each side by 3

3x/3 = 78/3

x =26

The three integers are 26, 28,30

The smallest is 26

815gal/h=_____qt/sec
AnnZ [28]

Answer:

Since there is 4 quarts in a gallon and 60 minutes in a hour.

60 x 60 = 3600

Multiply: 815  ×  4  =  3260  quarts per hour

So 3260/3600 = 326/360 = 0.905 quarts per second
