Step-by-step explanation:</h3>
Let "a" and "c" represent the numbers of adult and children's tickets sold, respectively. The problem statement tells us two relationships between these values:
... 20a +10c = 15000 . . . . . . total revenue from ticket sales
... c = 3a . . . . . . . . . . . . . . . . relationship between numbers of tickets sold
Using the expression for c, we can substitute into the first equation to get ...
... 20a +10(3a) = 15000
... 50a = 15000
... a = 15000/50 = 300 . . . . . adult tickets sold
... c = 3·300 = 900 . . . . . children's tickets sold
Answer:
8i
Step-by-step explanation:
-(root of 64)
but if you mean
root of -64 then it's 8i if you have learned complex numbers
can i get brainliest ;)
Answer:
in the explanation
Step-by-step explanation:
In a 30-60-90 triangle, the ratio of the leg opposite to 30 to the leg opposite to 60 to the hypotenuse is 1:
:2.
So, the 7 inch leg is the 1, the other leg is 7
in and the hypotenuse is 14 in.
Hope this helps!
Let the longer piece be x+5
Let the shorter piece by x
Both the wires together make 31cm so
x + x + 5 = 31
2x + 5 = 31
2x = 26
x=13
The shorter piece of the wire is 13cm.
