A jet plane flying 6000 m above the ground passed directly above Ana. one minute later, Ana noticed that the plane's angle of elevation was 18 degrees 34 minutes. What was the horizontal distance covered by the plane?
Tickets for a concert were sold to adults for $3 and to students for $2. If the total receipts were $824.00 and twice as many adult tickets as student tickets were sold, then how many of each were sold?
when we mix a 10% acid solution with a 14% acid solution, we can obtain a solution that is 24% acid
the sum of two numbers is -16 and their difference is 8, find the numbers
Find the sum of two numbers is 2, and their difference is 26. Find the numbers

oops, sorry my error total receipts $824
solve each system by substitution method x=y+3 3x-2y=4 Pls determine whether the equations are independent, dependent, or inconsistent
I calculated the M of NaBO.... at 6.59x10^-3 for the mass I measured. I have a chart of measurements where I used 9.98mL out of 100mL of solution that I made. I was given the equation (mass Na.../molar mass Na...)*(volume Na.../volume total solution) the balanced equation I...
I am working on a redox stoichiometry lab. I need to calculate the moles NaBO3*4H2O. Mass=1.0133g in 100mL solution In my experiment I used 9.98mL and titrated in with KMnO4. I'm really confused about how to calculate the moles. Thanks for any help!!!!
