Answer:

13/7, 221/182 and expansion, 507 inches

Step-by-step explanation:

If the two quadrilaterals are similar, you can take the diagonal length as a similar side to find the scale factor. In this case, the scale factor would be 13/7. For simplicity, we can keep this a factor for now. Because the quadrilaterals are similar, the scale factor is the same for all sides, 13/7. Because you are going from ABCD to EFGH and the scale factor is 13/7 (otherwise the other way around would be 7/13) and so the scale factor is greater than 1, you are expanding aka expansion. So, to find EF from side AB and you have the length 17/26, just multiply that by 13/7 to get 221/182 as the length.

To find the area of EFGH, you square the scale factor 13/7 and equal it to the area of EFGH A is over the area of the ABCD (you ratio them and set them equal) so 169/49 = A/147 and solve for A which is then 49A = 169 x 147 which is then 507 inches.

How much ₹ each will get if 242.46₹ is distributed equally among the students​
slavikrds [6]

<em>Complete Question:</em>

<em>How much ₹ will each get if 242.46₹ is distributed equally among the 6 students​ </em>

Answer:

Each of the 6 students will get ₹40.41

<em></em>

Step-by-step explanation:

Given

Amount = 242.46

Students = 6

Required

Determine how much each student gets

To do this, we simply divide the total amount by the number of students

i.e.

Each\ Students = \frac{Amount}{Number\ Students}

Each\ Students = \frac{242.46}{6}

Each\ Student = 40.41

<em>Hence, each of the 6 students will get ₹40.41</em>

Are these lines parallel or not: L1: (1,2), (3,1), and L2: (0,-1), (2,0)
Phoenix [80]

First find the slope of the first line

L1

m = ( y2-y1)/(x2-x1)

m = ( 1-2)/(3-1)

= -1/2

Now find the slope of the second line

L2

m= ( y2-y1)/(x2-x1)

= ( 0 - -1)/(2 -0)

= (0+1)/(2-0)

= 1/2

Parallel lines have the same slope

These lines do not have the same slope, they are different by a negative sign.

These lines are not parallel.
