Answer: It will take her 15 more hours to finish the book.
Step-by-step explanation:
25% : 5h
50% : 10h
75% : 15h
100% : 20h
It would take 20 hours to complete the book, but because she already read for 5 hours, it would be 15 to finish the book.
Use the formula for the area of a parallelogram:

Plug in what we know:

Convert both of them into improper fractions. We do this by multiplying the denominator to the whole number, adding it to the numerator, which becomes our new numerator, and we keep the denominator the same:

Now multiply the numerators and denominators together:

Convert it back into a mixed number. 14 goes into 555 thirty-nine times. 14 * 39 = 546. 555 - 546 = 9. So we have 39 wholes and 9 left over, or:

So this is the area of the parallelogram.
Given:
Image of the pyramid
To identify:
The cross section of the solid.
Solution:
The given image is a pyramid.
The base of the pyramid have 5 edges.
So, it is a pentagonal pyramid.
In the cross section also have 5 edges.
Therefore the cross section of the solid shown in the diagram is pentagon.
