Answer:
Adult ticket = 80
Children ticket = 120
Step-by-step explanation:
Given that :
Cost of student ticket = $8
Cost of adult ticket = $10
Number of tickets sold = 200
Total amount collected = $1760
Let number of adult ticket sold = a ; children ticket = b
a + b = 200 _-_(1)
10a + 8b = 1760 ___(2)
a = 200 - b
10(200 - b) + 8b =. 1760
2000 - 10b + 8b = 1760
- 2b = 1760 - 2000
-2b = -240
b = 120
a = 200 - b
a = 200 - 120
a = 80
Answer:
61
Step-by-step explanation:
Given the exponential expression, (2・3)² + 5²:
Start by multiplying 2 and 3 inside the parenthesis, before performing other mathematical operations.
(2・3)² + 5² = (6)² + 5²
Next, perform the exponential operations for (6)² and 5², then add their squared values together:
= 36 + 25 = 61

rc length=â«âšr2+(drdθ)2â‹…dθ
for a equation r=θ2,
drdθ=2θ
â´ Arc length=â«âšÎ¸4+4θ2â‹…dθ
by factoring out θ and rewriting a bit,

Answer:
The answer to your question is: 0° or 180°
Step-by-step explanation:
Equation
- 4 + 6 sin x = - 4 + 4 sin x
0° ≤ x ≤ 180°
6 sin x - 4 sin x = -4 + 4
2 sin x = 0
sin x = 0/2
sin x = 0
x = 0° or 180°
