Jonathan needs 70 L of 50 proof alcohol solution. He has 30% solution and a 80 solution available how many liters of the 30% solution and how many liters of the 80% solution would he mix to make 50% solution?

Write the equation below the represents the line passing through the point (-3, -1) negative one with a slope of 4

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?

1. are the triangles similar and if so why? what is the value of x? show your work.
