Students were packed shoulder to shoulder in a gym for a pep rally. the students were in a rectangular shaped area of 7,500
ft. if each student on average took up a circular space with a diameter of 2.5 ft what is the best estimate for the number of
students at the pep rally?
a)600
b)900
c)1,200
d)1,800

c)1200

Step-by-step explanation:

Given: Students were packed shoulder to shoulder in a gym for a pep rally. The students were in a rectangular shaped area of ft.

To Find: If each student on average took up a circular space with a diameter of ft what is the best estimate for the number of  students at the pep rally.

Solution:

Consider the figures attached

A student took up a circular space, if they were packed in rows each student acquired a circular space of ft and left some unused area as given in figures

Now,

Area acquired by a student is a square of side ft as given in figure

Area acquired by single student

Total number of students            

there are approximately students in gym hence option b is correct.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
