Answer:

Set up for both orders of integration for the integral below where R is the arc of a circle radius 2 in the first quadrant. Show that both orders produce the same result by integrating each of them.
∫ ∫(2x) dA
R
7x + 1 = x + 7
7(1) + 1 = 8
1 + 7 = 8
If you substitute 1 for x, the statement is true. Therefore, x = 1.

6. 36 mins
7. 3/4 < 33/40
8. 19/24 , 2/3 , 3/8
Step-by-step explanation:
Answer:
• For this one we need to split this problem into two equations:
• a (adults) + c (children) = 560
• 2a + c = $860
• Then we substitute 560 - a for c in the second equation.
- 2a + 560 - a = 860
- 2a + 560 = 860
- 2a = 530
- 2a = 265
• Then we plug this into the first equation:

Answer:
72 minutes!
Step-by-step explanation:
We can form the linear equation :
y = 0.06x + 8
y = 12.32
12.32 = 0.06x + 8
4.32 = 0.06 x
x = 72
tadah!
