You’re finding the difference between the two numbers (subtraction). 1/4 is 0.25.
40.25 - 38.75 = 1.5
She worked one and a half more hours in the second week.
Answer:
AC = 
Step-by-step explanation:
Here we have to draw the figure.
When the rectangle is folded A to C. we get a right triangle.
Here we have to use the Pythagorean theorem to find the side lenght of B.
The sides length of B is AC.
By the Pythagorean theorem, the sum of the squares of the sides is equal to the square of the hypotenuse.
Therefore,
AC^2 = AB^2 + BC^2
Taking the square roots on both sides, we get
AC = 
To get the result we have to find 20% of 22.58.
First we have convert 20% into decimal.
20% its 0.20
Finally we can multiply 0.2 and 22.58.
0.2*22.58=4.516 - its the answer
I hope this helps you
