Answer:
x = ±sqrt(2)
Step-by-step explanation:
8x^2 - 5 = 11
Add 5 to each side
8x^2 - 5+5 = 11+5
8x^2 = 16
Divide each side by 8
8x^2 = 16/8
x^2 = 2
Take the square root of each side
sqrt(x^2) = ±sqrt(2)
x = ±sqrt(2)

Answer:
12 bats
Step-by-step explanation:
Let us number the bat caves from 1 to 45 and divide them into 5 parts:
a) 1
b) 2 to 29 (
bats)
c) 30
d) 31 to 44 (
bats)
e) 45
It is given that any 7 caves in a row has 77 bats. Hence, the total number of bats in part b and d =
bats.
There remains
bats in cave number 1, 30 and 45.
Now, our question demands the maximum possible number of bats in cave 30.
Minimum number of bats in a cave is 2. So we shall put 2 bats in the last cave, which gives us
bats in the first cave.
Therefore, the number of bats in cave number 30 =
bats.
