An irrational number cannot be expressed as a ratio between two numbers so putting a decimal makes it irrational
It will take the snail 9.6 minutes to travel 24cm.
Step-by-step explanation:
Distance covered in 4 minutes = 10 cm
Ratio of distance to time = 10:4
New distance = 24cm
Let,
x be the time period
Ratio of new distance to time = 24:x
Using proportions;
Ratio of distance to time :: Ratio of new distance to time
Product of mean = Product of extreme
Dividing both sides by 10
It will take the snail 9.6 minutes to travel 24cm.

Answer:
x = 7 & y = 8
Step-by-step explanation:
We know that
Mean = Sum of terms/Total terms
=> Mean = 4 + 6 + x + y + 10/5
=> Mean = 20 + x + y/5
Now,
Median = (n + 1)/2
=> Median = (5 + 1)/2
=> Median = 6/3
=> Median = 3rd term = x
So,
x = 20 + x + y/5
x × 5 = 20 + x + y
5x = 20 + x + y
5x - x = 20 + y
4x = 20 + y
Since x and y are in order so,
Possible outcomes will be 7,8 & 9
(7,8) & (8,9) & (7,9)
Taking x = 7 and y = 8
4(7) = 20 + 8
28 = 28
Hence,
x = 7 and y = 8
Answer:
10 inches
Step-by-step explanation:
Surface Area = π R² + π R L [ L is Slant Height ]
200 π = π (10)² + π (10) L
200 π = π (100) + π (10) L
200 π - 100 π = 10 π L
100 π = 10 π L
100 π / 10 π = L
10 = L
L = 10 inches
