x = 5.3 hours
Answer:
25%
Step-by-step explanation:
12=100%
3=25%
9=75%
Well if you add them all together you would get 25. You would have 9/25 red marbles. Then you would take 9 and divide it by 25 and get 0.36 and if you move the decimal over 2 places you’ll get 36%
Mia’s first error was " she forgot to multiply π by (17.5)²(47) "
Step-by-step explanation:
The formula of the volume of a cylinder is V = π r² h, where
- r is the radius of the base of the cylinder
- h is the height of the cylinder
∵ The diameter of the base of the cylinder is 35 meters
∵ The radius =
× diameter
∴ The radius =
× 35 = 17.5 meters
∴ r = 17.5
∵ The height of the cylinder = 47 meters
∴ h = 47
- Substitute r and h in the formula of the volume
∴ V = π (17.5)²(47)
∵ Mai's first step is V = (17.5)²(47)
- She forgot to put π
∴ Her first error is she forgot to multiply π by (17.5)²(47)
