You use sine, cosine, or tan
let h be the number of hours then
A → C = 150h + 250 ( where C is charge )
B → C = 175h + 150
for 26 hours
A → C = (150 × 26 ) + 250 = 3900 + 250 = $4150
B → C = (175 × 26 ) + 150 = 4550 + 150 = $4700
Attorney A is cheaper for 26 hours, thus better deal
Equate the 2 equations to find hours they charge the same
175h + 150 = 150h + 250 ( subtract 150h from both sides )
25h + 150 = 250 ( subtract 150 from both sides )
25h = 100 ( divide both sides by 25 )
h = 4 ← number of hours when charges for both are equal
Thus Attorney A becomes a better deal at 5 hours
It’s 20cm :) because knowing that you have a 3:5 ratio and that one side is 12 can you can make a ration table so 3:5 and 12:? And to get from 3 to 12 you have to multiply 3 by 4 so you have to do the same to the other side 5 times 4 is 20 so 20 cm
Just say your problem that you have and go over it or make a song or you can do some problems on a piece of paper or write the steps of the area that you have to do or do problems that you get messed up on hope that helps and if you have any questions just ask
