There are two quantities of salt solution: 80g and 120g. in the first solution there are 12g of salt, in the second solution there are 15g of salt. what is the concentration (in percent) of salt in each solution? what would be the concentration if we were to mix these solutions?

1. if sin t=.29 and ,sin w=.43 both t and w are positive, and the angles determined by t and w are in quadrant 2, then which of the following statements is true? a. t > w b. w > t c. cannot be determined 2. if cos t=-.42 and ,cos w=-.80 both t and w are positive, and the angles determined by t and w are in quadrant 3, then which of the following statements is true? a. t > w b. w > t c. cannot be determined
