Answer:
the cost for each drink = $2.54
Step-by-step explanation:
The statement formed a simultaneous equation :
3x + 6y = $21.12
4x + 9y = $30.41
solving simultaneously,you have that ; x = 2.54, y = 2.25
The sum of all angles in a triangle is 180 degrees
Our given angles 55+45+90=190 degrees
We can make 0 triangles with those given angle measurements.
Multiply the investment fraction by the corresponding return, and add the products. The given fractions add to 59%, so the remainder is 41%. (The total of the fractions is 100%—all of the portfolio.)
... 0.43*9.1% + 0.16*16.7% + 0.41*11.4%
... = 3.913% + 2.672% + 4.674% = 11.259%
