RSB [31]

The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.

Answer:

156 were there on the fourth day.

Step-by-step explanation:

125% of the number she received on the previous day

This means that the previous day number is multiplied the 125%/100% = 1.25.

64 responses the first day

This means that the number of responses after x days is given by:

$R(x) = 64(1.25)^x$

How many were there on the fourth day?

This is R(4). So

$R(4) = 64(1.25)^4 = 156$

156 were there on the fourth day.
