For number 12 you need to make an expression using the information given. a) 25g + 18r + 15b could be the expression.
b) The variables would be 25g for the 25 gold seats, 18r for the 18 red seats and 15b for the 15 blue seats.
c) Plug in the number given according to the variables.
25(100) + 18(250) + 15(200)
2500 + 4500 + 3000
7000 + 3000
$10,000
Answer:
see explanation
Step-by-step explanation:
given f(x) in factored form, set f(x) = 0 and solve, that is
(x + 16)(2x - 3)(3x + 4) = 0
Equate each factor to zero and solve for x
x + 16 = 0 ⇒ x = - 16
2x - 3 = 0 ⇒ 2x = 3 ⇒ x =
3x + 4 = 0 ⇒ 3x = - 4 ⇒ x = -
The zeroes are
x = - 16, x = , x = -
In 2008, up to 405 messages could be sent without spending more than $ 100.
Since in 2008, text messages were charged per text, and some carriers charged $59 for a basic text package of 200 texts and 20 cents per text after that, while today, most packages include unlimited text and data but cost closer to $ 100 a month, to determine the range of text messages you can send with the 2008 plan without spending more than $100, the following calculation must be performed:
- (41 / 0.2) + 200 = X
- 205 + 200 = X
- 405 = X
Thus, in 2008, up to 405 messages could be sent without spending more than $ 100.

Answer:
A) When using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. True.
The Shell method is a technique used to find the volume of a solid of revolution. Here, we take thin shells with axis coinciding with the axis about which the region whose volume is to be found, is revolved.
B) If a region is revolved about the y-axis, then the shell method must be used. False.
This method can be used with any axis of rotation.
C) If a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y. True.
The washer method uses thin disks with infinite width but the shell method uses thin concentric shells with infinite width about the axis of revolution. So, the statement is true.
Answer:
B) 72
Step-by-step explanation:
28+(17x+4)=4+24x
17x+32=24x+4
32=24x-17x+4
32=7x+4
7x=32-4
7x=28
x=28/7
x=4
WGH=17x+4=17(4)+4=68+4=72
