Answer:
90% of the club member voted for Leila
Step-by-step explanation:
Leila ran for president of the chess club and she received 36 votes . The club has a total of 40 members . The percentage of the club member that voted for her can be computed below.
total member of the club = 40
number that voted for her = 36
a% of 40 = 36
a/100 of 40 = 36
40a/100 = 36
cross multiply
40a = 3600
divide both sides by 40
a = 3600/40
a = 90
%
90% of the club member voted for Leila

Answer:
180.07 rev / min
Step-by-step explanation:
Diameter (D) of each wheel =28 inches
Circumference (C) = π x 28 = 28π inches
Conversions:
1 mile = 63,360 inches
1 hour = 60 min
Hence 15 miles / hour
= (15)(63,360) inches / hour
= (15)(63,360) / 60 inches / min
= 15,840 inches per min
Number of revolutions per min = Number of inches per min ÷ circumference in inches
=15,840 inches/min ÷ 28π inches
= 180.07 revolutions per min
