It is given that
Jeremy is reading a 60-page book.
The time taken to read 20 pages is 30 minutes
Then it can be written as 20:30 = 2:3
The rate of reading is same so To read the rest 40 pages is given by
40:x
40: x = 2:3
40*3/2 = x
x = 60 minutes
Therefore it will take total 90 minutes to finish the book and 60 minutes to read the left 40 pages.

8 - 8 / 2 + 7^2
PEMDAS Parenthesis Exponents Multiplication Division Addition Subtraction
Exponents 7^2 = 49
8 - 8 / 2 + 49
Division 8 / 2 = 4
8 - 4 + 49
Addition 4 + 49 = 53
8 - 53
Subtraction 8 - 53 = -45

Given:
A square base pyramid with base length 6 cm and the slant height is 4 cm.
To find:
The lateral surface area of the given square pyramid.
Solution:
The lateral surface area of the given square pyramid is equal to the areas of 4 congruent triangles with base 6 cm and height 4 cm.
Area of a triangle is:
So, the area of one triangle or one side of the given pyramid is:
Now, the lateral surface area of the given square pyramid is 4 times the area of one triangle.
Therefore, the lateral surface area of the given square pyramid is 48 cm².
