Clark School has to schedule 6 teams to eat lunch. The cafeteria holds 135 students. A unch wave is 25 minutes long, Lunch can be served between 10:45 and 12:25. Teams can be
split up into 2 different lunch waves as long as they are right next to each other, Make up a
schedule to tell the times of the lunch waves and how many students from each team should
attend each lunch wave. The teams and number of students on each team are shown below.
Cowboys
78 students
Giants
98 students
Patriots
81 students
Jets
54 students
Titans

i got 10.28 but that rounds up to 10.3

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

b is the correct answer
