Answer:
r = 6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
PR² = PQ² + QR² , substitute values
(r + 4)² = r² + 8²
r² + 8r + 16 = r² + 64 ( subtract r² from both sides )
8r + 16 = 64 ( subtract 16 from both sides )
8r = 48 ( divide both sides by 8 )
r = 6
So B is 6x bigger than figure A and A is only half the size of B
Answer:the answer is 44
Step-by-step explanation: cuz 40 divided by 90%= 44
The solution to the problem is as follows:
<span>7(4)/4(4) = 28/16
28+16= 44

Therefore, the size of the graduating class would be 44 students in all.
I hope my answer has come to your help. God bless and have a nice day ahead!
