Answer:
The height is 17 ft
Step-by-step explanation:
The surface area of a rectangular prism is
SA = 2(LW +WH + LH)
where L = length, W = width, and H = height
We know SA = 930, L = 12, and W = 9
930 = 2(12*9 +9H + 12H)
Divide each side by 2
930/2 = 2/2(12*9 +9H + 12H)
465 = (12*9 +9H + 12H)
Combine like terms
465 = 84+21H
Subtract 84 from each side
465-84 = 84-84+21H
357 = 21H
Divide by 21
357/21=21H/21
17 = H
The height is 17 ft

Step-by-step explanation:
A recipe for sabayon calls for 2 egg yolks, 3 tablespoons of sugar, and ¼ cup of white wine. After cracking the eggs, you start measuring the sugar, but accidentally put in 4 tablespoons of sugar. How can you compensate?
Note that we put in 4/3 more sugar than we wanted, because 3(4/3) = 4
So we need to increase eveything else by 4/3
So 2(4/3) = 8/3 = 2 +2/3 egg yolk and (1/4)(4/3) =4/12 = 1/3 cup of wine
Answer:
C is the answer
C ) y = 
Step-by-step explanation:
2 y - x = 
( -y + 1)
(2 y - x ) 4 = 3 ( -y +1)
8 y - 4 x = -3 y + 3
8 y + 3 y = 4 x + 3
11 y = 4 x + 3
∴ y = 
Try 9:2 and 3:1 but I'm not sure if that's right or not
