Answer:
The answer is C.
Step-by-step explanation:
Both temporary and permanent magnets have below common specifications:
-Repels or attracts other magnets
-Attracts iron objects
Therefore, choices <u>B</u> and <u>D</u> is wrong.
Maintaining magnetic properties in the presence of another magnet and made from magnetically hard ferromagnetic material are both specification of permanent magnets. Thus, A is also a wrong choice.
So the answer is C.
Answer:
A
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° =
=
= 
Multiply both sides by 7, thus
AC = 7sin40° → A
Answer:
23 or more chairs.
Step-by-step explanation:
There are 5 tables to start. Each tables is 450 dollars.
5x450=2250
4500-2250=2250
2250(money still need to be made) divided by 100(the price of a chair)=22.5
Since you can't have a half of a chair but you cant have any less, you round it up to 23 chairs. The answer is 23 or more chairs.
