Starting from a 130 feet away, a person on a bicycle rides towards a checkpoint and then passes it. The rider is traveling at a constant rate of 25 feet per second. The distance between the bicycle and the checkpoint is given by the equation: d = |130 - 25t|. At what times is the bike 15 feet away from the checkpoint? a. 4.6 sec and 9.2 sec

b. 2.9 sec and 5.8 sec

c. 4.6 sec and 5.8 sec

d. 2.9 sec and 3.3 sec

Answers

Answer 1

Answer: for this question you can say d = 15 feet so we need the t then you can say :
15 = l 130 - 25t l ⇒ because of the absolute value you should say :
1) 130 - 25t = 15 ⇒ -25t = 15 - 130 ⇒ - 25t = -115 ⇒ t = 115/25 = 4.6 sec

2) 130 - 25t = - 15 ⇒ -25t = -15 - 130 ⇒ -25t = - 145 ⇒ t = 145/25 = 5.8 sec
so the answer is c :))

Harrison mows lawns and rakes leaves for his summer and fall weekend jobs. He gets $10 an hour to mow lawns and $8 an hour to rake leaves. If, during September, Harrison mows for m hours and rakes for 12 hours, which expression represents the amount of money he makes

Answers

The expression which represents the amount of money he makes is 10m + 96

How to be write mathematical expression?

Amount earned per hour for lawns = $10
Amount earned per hour to rake leaves = $8
Number of hours mowed = m
Number of hours raked = 12 hours

Total amount of money earned = (10 × m) + (8 × 12)

= 10m + 96

Therefore, the expression which represents the amount of money he makes is 10m + 96

Dena's softball team can win (W) or lose (L) each game. Which of the following are elements in the sample space for 2 softball games?

Answers

In a softball game, the odds are only win or lose the game. When 2 games are already being considered, the elements in the sample space are already 2 in each set. The sets are {W,W}, {W,L}, {L,W} and {L,L}. Hence, there are 4 sets all in all to describe the odds of the two games.
