Answer:
46
Step-by-step explanation:
If you take the fraction and divide it 2/11, it'll give you the decimal form of what you need, which will give you .18
Now your equation has become 254*.18, which you multiply instead of divide because you switched the form it is given in, and if you try to divide it will give you some obscure number.
Your answer from 254*.18 is 45.72, which you cant give .72 of a book, therefore you round up, making it so he has donated 46 books.
0789 is the smallest
9870 is the largest
Answer:
EF = 8.8 cm
Step-by-step explanation:
In the given right angled ΔDEF, DE is the hypotenuse while EF and DF are adjacent sides. So that applying the Pythagoras theorem, we have;
= 
+ 
= 
+ 
= + 
262.44 = + 184.96
= 262.44 - 184.96
= 77.48
EF = 
= 8.8023
EF = 8.8 cm
The length of side EF is 8.8 cm.
