2300 cups because if 460 is 20%, multiply the 460 x 5 to get 100%
40 students prefer vanilla. To get this answer you need to multiply 200 times 0.2 because you are trying to find 20%
The approximate length of rail that needs to be replaced is 7.1 ft
<h3>Length of arc</h3>
Since the pool is circular, the approximate length that needs to be replaced is an arc of length, L = Ф/360° × πD where
- Ф = central angle of rail section = 27° and
- D = diameter of circular pool = 30 ft
<h3>Approximate length of rail</h3>
So, substituting the values of the variables into the equation, we have
L = Ф/360° × πD
L = 27°/360° × π × 30 ft
L = 3/40 × π × 30 ft
L = 3/4 × π × 3 ft
L = 9/4 × π ft
L = 2.25 × π ft
L = 7.07 ft
L ≅ 7.1 ft
So, the approximate length of rail that needs to be replaced is 7.1 ft

Answer:
1.5
Step-by-step explanation:
If 1 tablet is 100mg, and you need 150mg, we set up this equation:
Let x be the number of tablets Coco needs.
x = 150/100
x = 1.5
Therefore, you need 1.5 tablets for the medication.
