Answer:34 degrees
Step-by-step explanation: they are the same angle
Out of a sample of 80 books, 6 were historical books. So the percentage of books in the sample will be:
%
We can use this sample to represent the entire collection of books in the library. So the best estimate of total number of historical books in the library is 7.5% of 21360 , which comes out to be:
7.5 % of 21360 =
Therefore, roughly 1602 books out of 21360 book of library are historical books.
Option B:
Surface area of the solid is 730 square millimeters.
Solution:
Area of the rectangle = length × breadth
Length of the top net = (25 + 8 + 8) mm = 41 mm
Breadth of the top net = 5 mm
Area of the Top net = 41 mm × 5 mm
= 205 square mm
Area of the second net = 25 mm × 8 mm
= 200 square mm
Area of the third net = 25 mm × 5 mm
= 125 square mm
Area of the bottom net = 25 mm × 8 mm
= 200 square mm
Surface area of the solid = 205 mm + 200 mm + 125 mm + 200 mm
= 730 square mm
Hence surface area of the solid is 730 square millimeters.
Option A is the correct answer.
