Using b as the variable for the problem below, solve for b. Submit your answer as an inequality, using "<=" for or ">=" fo r if necessary. Round to one decimal place. In a team bike race, each biker has to ride exactly 50 miles. If a team must complete 560 miles, at least how many bikers are on each team?
1 answer:
Number of bikers: b miles ridden by each biker: 50 number of miles ridden by the team: 50b Condition: 50b ≥ 560 => b ≥ 560 / 50 => b ≥ 11,2 Given that b refers no number of persons it has to b an integer and b has to be at least 12 => b ≥ 12. If there would be 11 bikers the team only could complete 11*50 = 550 miles, so they cannot complete the required 560 miles.Answer: b ≥ 12

Answer:
C. 120 students
Step-by-step explanation:
10 + 15 + 20 +30 = 75%
100 - 75 = 25%
25% chose football which is 100 students
30% chose swimming
setup proportion:
25/100 = 30/x
25x = 100(30)
25x = 3000
x = 120
Check the picture below.
thus is at 0 = -16t² + 96t +640,
well, clearly it can't be a negative value for the elapsed seconds, so it can't be -4.
(0,-4) would map into itself because it doesn’t move.
