please help me figure out the length of side AC!!!! i put the points at 16! i need this by the 21st :(
Ilia_Sergeevich [38]

Answer:

AC = \sqrt{89} units²

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse AC is equal to the sum of the squares on the other 2 sides, that is

AC² = AB² + BC² = 5² + 8² = 25 + 64 = 89 ( take square root of both sides )

AC = \sqrt{89} ≈ 9.43 ( to 2 dec. places )

Mr.Johnson purchased 20 concert tickets for a total of $225. The concert tickets cost $15 for adults and $10 for children under
taurus [48]

Answer:

15

Step-by-step explanation:

Let the number of adult tickets be x while children ticket be y. Since the total tickets were 20 then we can form the equation

x+y=20

Making x the subject then x=20-y

Considering the cost of each ticket

15x+10y=225

Substituting x with 20-y then

15(20-y)+10y=225

300-15y+10y=225

Collecting like terms

300-225=15y-10y

75=5y

Y=75/5=15

To find x, we already know that x=20-y hence x=20-15=5

Therefore, children tickets are 15 while adult tickets are 5.

The question only needs us to know the children tickets, y which is 15
