a laboratory technician is developing cleaning solution that will remove stains from clothes. the technician mixes a 20% acid solution with a 5% acid solution. how much of each solution to the nearest millimeter is needed to make 150 milliliters of a 15% acid solution. Set up a system of equation for the given situation. You do not need to solve these.

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
