Answer:
26 socks
Step-by-step explanation:
There are a total of 48 socks here. Let us assume you pulled out 24 socks at a go and all are red. Now, you would have exhausted the number of red socks here. You would be left with only blue socks which you can pull one after the other to give a total of 26 socks pulled out to have 2 blue socks at least.
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 : bru
Step-by-step explanation:
Answer:
a n = -3+(n-1)-30
Step-by-step explanation:
-3 - 30 = -33
-33 - 30 = -63
-63 - 30 = -93
The common difference here is -30. d = -30
The explicit formula is a n = a1 + (n-1)d
A, because: 20x10 1/2=210
And 20x11 1/4=225
And 225-210=15
So thats the answer.
