Lee needs 3,156 yards of red ribbon for her craft store. She buys the ribbon in rolls of 24 yards each. How many rolls does she need to buy?

Step-by-step explanation:

Total yards = 3156

No of yards in each roll = 24

Rolls she needs to buy = 3156 ÷ 24 = 131. 5 rolls

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
