A school chorus has 90 sixth-grade students and 75 seventh-grade students. The music director wants to make groups of performers
Vera_Pavlovna [14]

Answer:

a) 15 is the largest number of groups that can be made.

b) There would 6 sixth grade students and 5 seventh grade students in each group.

Step-by-step explanation:

Number of sixth-grade students = 90

Number of seventh-grade students = 75

a) What is the largest number of groups that could be formed?

Since the music director wants to make groups with the same combination of sixth and seventh grade students in each group,

The greatest common factor (GCF) of the number of sixth and seventh grade students would give us the required combination.

Factor of 90 = 2*45 = 2*3*15 = 2*3*3*5

Factor of 75 = 3*25 = 3*5*5

The greatest common factors are 3 and 5

GCF = 3*5 = 15

Therefore, 15 is the largest number of groups that can be made.

b. If that many groups are formed, how many students of each grade level would be in each group?

Sixth grade = 90/15 = 6

Seventh grade = 75/15 = 5

Therefore, there would 6 sixth grade students and 5 seventh grade students in each group.

On top of a hill, a rocket is launched from a distance 80 feet above a lake. The rocket will fall into the lake after its engine
lisov135 [29]
For this case we have the following equation:
 h = -16t2 + 64t + 80
 To find the maximum height, we derive the equation:
 h = -32t + 64
 We match zero:
 -32t + 64 = 0
 We clear t:
 t = 64/32
 t = 2
 We substitute the value of t in the given equation:
 h (2) = -16 * (2) ^ 2 + 64 * (2) + 80
 h (2) = 144
 Answer:
 
The maximum height is 144 feet and the time to reach this height is 2 seconds.
