B. addition and subtraction
Answer:
350 feet per minute
Step-by-step explanation:
The amount of time it took the plane to descend is 3 hours 14 minutes minus 1 hour 30 minutes.
This means it took 104 minutes for the plane to descend 36,400 feet.
Dividing 36400 by 104, you get 350 which is the average rate of descent in feet per minute.
To find the percentage of students on the swim team all you have to do is divide the amount of students in it by the complete number of students. (66/300) That should give you your answer which is around 22%.
Answer:
They will not have the same weight during the program
Step-by-step explanation:
Let x be the number of weeks.
<u>Sandra:</u>
Sandra is starting at 150 pounds and plans to lose 1 pound a week.
Weight after x weeks:

<u>Bernice:</u>
Bernice is starting at 135 pounds and plans to lose 1/2 a pound a week.
Weight after x weeks:

Weights must be the same, so

Since 30 weeks is more that 12 weeks (the duration of the program), they will not have the same weight during this program.
Since the .23 is lower than 4 the whole number 23 STAYS THE SAME.
23.0
