Eric conducted a survey of the cars in four parking lots and wrote the following observations:
15 of the 36 cars in lot 1 were blue
43 of the 92 cars in lot 2 were blue
12 of the 30 cars in lot 3 were blue
32 of the 52 cars in lot 4 were blue
based on the survey, which parking lot had the greatest percentage of blue cars?

quick way the one with the 2 closest numbers

 other way divide all 4 options

15/36 = 0.41 = 41%

43/92 = 0.46 = 46%

12/30 = 0.4 = 40%

32/52 = 0.62 = 62% Lot 4 had highest percent

lot 4

Step-by-step explanation:

i took the test and got it right.  32/52 as a percentage is 61.538461538462% making it the highest percentage of them all.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

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
