Step-by-step explanation:
b. Molly make mistake when he/she divide all equation by 4 but left the 8x remain 8x, it should be 2x.
Mark make mistake in changing the sign whitout changing side/ passing trough equal sign. FYI, + can be - and also - can be + if they move to the other side
i.e.
2 + 3 = 5
2 = 5 - 3
Sphere = 4/3 πr^3
4/3 π (3^3) = 36π = 36*3.14 = 113.04 ft^3
Answer: $9.40

Answer:
foot = 5 ft
luff = 20 ft
Step-by-step explanation:
In the picture attached, the diagram of the sail is shown. A right triangle is formed, where 50 ft² is its area, which can be computed as follows:
foot*luff*1/2 = 50
We also know that luff = 4*foot. Replacing into the previous equation:
foot*(foot*4)*1/2 = 50
foot²*2 = 50
foot² = 50/2
foot = √25
foot = 5 ft
luff = 4*5 = 20 ft
