Answer:
c = 25
Step-by-step explanation:
A^2 + B^2 = C^2.
25^2 + 15^2 = 625 THIS IS NOT THE ANSWER BECAUSE WE WANT C NOT C^2!!! So, we have to find the square root. √625 = 25.
This is what you do.
(3)^(-9+7)= (3)^(-2)
= (1/3)^2
=1/9
C = 2PIr
C = 2 * 3.14 * 3 = 18.84 cm
Answer:
Adult= $11
Children = $7.5
Step-by-step explanation:
Let x represent adult ticket and y represent children ticket
2x + 3y= 44.50........equation 1
3x + 6y= 78........equation 2
From equation 1
2x + 3y= 44.50
2x= 44.50-3y
x= 44.50-3y/2
Substitute 44.50-3y/2 for x in equation 2
3x+ 6y= 78
3(44.50-3y/2) + 6y= 78
66.75- 4.5y +6y= 78
66.75 + 1.5y= 78
1.5y= 78-66.75
1.5y= 11.25
y= 11.25/1.5
y = 7.5
Substitute 7.5 for y in equation 1
2x + 3y = 44.50
2x + 3(7.5)= 44.50
2x + 22.5= 44.50
2x = 44.50-22.5
2x= 22
x= 22/2
x= 11
Hence the price of adult ticket is $11 and the price of children ticket is $7.5
