Answer:
600 ft in one minute
i don't know if my answer is correct or not
Step-by-step explanation:
Object 1 280 ft/min => 85 m/min => 85/60 m/sec
sim.
Object 2320 ft/min => 98 m/min => 98/60 m/sec
when two bodies move in opp. direction there speeds are added
so
resultant speed is object 1 + object 2
the resultant comes out as 183/60 m/sec
time is given 1 minute
and we know Distance = time * speed
distance = 183/60 * 60 (183/60 is the speed and 60 is the time in sec as 1 min. = 60sec)
so the distance comes out as 183 m
convert it into ft
1m = 3.2 ft
so 600 ft in one minute
Answer:
1,414 students in the high school are not freshman
Step-by-step explanation:
Since 30% of the high school students are freshman, then the remaining students must be anything but freshmen (sophmores, juniors, seniors). The entire student population must equal 100%, so 100 - 30 = 70% of the students that are not freshman. When calculating with percentages, we must first convert them to decimals by dividing by 100: 70/100 = 0.70. If there are 2020 students in the high school, multiplying the total number by the 70% that are not freshman, will give us the total amount:
2020 x 0.70 = 1,414
Answer:
B
Step-by-step explanation:
The common ratio r exists between consecutive terms in the sequence, that is
r = - 62.5 ÷ 12.5 = 312.5 ÷ - 62.5 = - 1562.5 ÷ 312.5 = - 5
