Maki uses 20 gallons of a solution with an unknown ethanol concentration and 60 gallons of a 12% ethanol solution to make 80 gallons of a 10% solution. the table shows the amount of each solution.

a table titled ethanol mixture, showing gallons, ethanol concentration, and total. the first row shows x percent ethanol, 20, x, and blank. the second row shows, 12 percent ethanol, 60, 0.12, and 7.2 the third row shows mixture, with 80, 0.10, and blank.

what is the value of x, the concentration of the unknown ethanol solution?

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

you have to put the graph on here with the question
