Before the assembly began, only 35 percent of the students were seated. If 91 students were not seated, how many students were there in all?

Answers

total=100%
seated==35%
100%-35%=65%=not seated

91=not seated=65% of of all

91=65% of all
91=0.65 times all
divide both sides by 0.65
140=all

49w^2-4=0. Simplied fraction?

Answers

Answer:

{-2/7, 2/7}

Step-by-step explanation:

Here you're being asked to solve the given equation 49w^2-4=0 for w with the hint that the solutions are fractions.

49w^2-4=0 is the product of the sum and difference of two squares:

(7w - 2)(7w + 2) = 0

Setting each factor equal to zero and solving for w, we get:

{-2/7, 2/7} as the solutions.
