You don't give much information but I will give you the definition of "density".
In all simpleness, the definition of density is the compactness of a substance.
Density can be found with the formula; p = m/v
p = density
m = mass
v = volume
Best of Luck!
Answer:
Step-by-step explanation:
11. I can't see the full problem statement, so I'm unable to answer the question.
12. Answer below:
"one half" =
"negative five eighths" =
To evaluate the expression, you multiply the two numbers together:
13. Answer below:
"one third" =
"eleven sixteenths" =
To evaluate the expression, you multiply the two numbers together
Since it is a right angle you would subtract 57 from 90 because both angles added together are 90°. 90-57= 33°
<u>Answer:</u>
D) R0 , 360°
<u>Explanation:</u>
<u>We are given that the rotation is:</u>
(x,y) --------> (x,y)
This means that the point is rotated back into its original position.
This means that full rotation occurred.
Since the full rotation is 360°, therefore, the correct answer is D
<u>For the other options:</u>
<u>Rotation 90° gives:</u>
(x,y) ----------> (-y,x)
<u>Rotation 180° gives:</u>
(x,y) ----------> (-x,-y)
<u>Rotation 270° gives:</u>
(x,y) ---------> (y,-x)
Hope this helps :)
