A) -15 > -5 is false.
B) -4 > 0 is 0 < -4
C) -12 < -3 is always true. There are many solutions.
D) 2 < -5 is false.
Answer: C) -12 < -3
Answer:
5 L
Step-by-step explanation:
As given in question,
1 L can fill 4.2 cups.
So, 1 cup can hold
L of fluid.
Therefore,
21 cups can hold =
× 21
= 5 L
So, there is 5 L of fluid in 21 cups.
Answer:

Step-by-step explanation:
The arcs LY, KM, KL and MJ together form the full revolution angle, thus

Note that

then

So,

Also

so

In triangle EML,

Thus, 
Answer:
sin θ = 
Step-by-step explanation:
Given that,
cos θ = 
From the trigonometric functions,
cos θ = 
⇒ adjacent =
, and the hypotenuse = 3
Let the opposite side be represented by x, applying the Pythagoras theorem we have;
=
+ 
=
+ 
9 = 3 + 
= 9 - 3
= 6
x = 
Thus, opposite side = 
So that,
sin θ = 
= 
Therefore,
sin θ = 
This depends. The way you do this is by taking these two points and by adding their absolute values together, this therefore finds their difference. This only works if one number is positive and one in negative. If two numbers are on the same side of the number line you CANNOT find their difference with absolute value.
