Adam has a total of 18 coins made up of dimes and nickels. The total amount is 125 cents. How many dimes and how many nickels does he have?

7 dimes and 11 nickles

Step-by-step explanation:

dime= 10 cents 10×7=70

Nickle= 5 cents 11×5=55

55 cents + 70 cents = 125 cents

*And 7 coins + 11 coins = 18 coins

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
