One pattern believe fabric sells for $15 for every 2 yards, and another sells for 37.50 every 5 yards do these fabrics have the
Elenna [48]
We need to find out how much is worth one yard in both fabrics, so we divide $15.00 by 2 and $37.50 by 5:

$15.00 ÷ 2 = $7.50 per yard
$37.50 ÷ 5 = $7.50 per yard

As both prices per yard are the same, the answer is: <span>Yes, these fabrics have the same unit cost.</span>

The figure shows two parallel lines KL and NO cut by the transversals KO and LN.
Sever21 [200]

Answer:

(A)  

Step-by-step explanation:

From the given figure, we have to prove whether the two given triangles are congruent or similar.

Thus, From the figure, ∠3=∠4 (Vertically opposite angles)

Since, KL and NO are parallel lines and KO and LN are transversals, then

measure angle 1= measure angle 5 that is ∠1=∠5(Alternate angles).

Thus, by AA similarity rule, ΔKLM is similar to ΔONM.

Thus, Option A that is Triangle KLM is similar to triangle ONM because measure of angle 3 equals measure of angle 4 and measure of angle 1 equals measure of angle 5 is correct.

Find the equation of the line
Gre4nikov [31]

Answer:

y= - 1/6x -1

Step-by-step explanation:

Given:

  • y= 6x -2
  • and point (6, -2)

Perpendicular line has slope of reciprocal opposite to the given: - 1/6, so the equation:

  • y= -1/6x + b

Finding b using the intersected point:

  • -2= -1/6*6 +b
  • b= -2 +1= -1

So the equation is:

  • y= - 1/6x -1
