We have been given that that there are 8 boys from Wilmette, 5 girls from Kenilworth, 9 girls from Wilmette, 5 boys from Glencoe, 5 boys from Kenilworth and 7 girls from Glenoce.
The total number of students from Kenilworth is 5 boys plus 5 girls that is 10 students.
The total number of students in the class would be 





Therefore, the probability, that the student will be from Kenilworth, is approximately 0.256.
Answer:
Step-by-step explanation:
a + b = 3b
a = 3b - b
a = 2b
a/b = 2/1
a:b = 2:1
Answer:
Step-by-step explanation:
We need to figure out how far Eric's car takes him in 1 rotation based on the diameter of his tire in feet. If the diameter of the tire is 18", then it is 1.5'. The circumference will tell us the distance 1 rotation of his tires will take him:
C = 3.1415(1.5) so
C = 4.71225 feet is how far he goes in 1 rotation. If he travels 88 feet in 1 second, we can figure the number of rotations by dividing 88 by 4.71225 to give us the unit rate (or, rotations per second his car makes). This quotient is 18.67 feet per sec, which rounds to 19, choice B.
