I think I'd be the $40 she charges every hour she works. If this is multiple choice mind drop-in the options
Answer:
Y=168
Step-by-step explanation:
Y varies directly as X
Y=kx
K is a constant
28=k2
K=28/2 =14
Y=14x
Y=14×12
Y=168
Recall the double angle identity:
With 
measuring between 0º and 90º, we know 
. So from the Pythagorean identity, we get
Then
Answer:
20, 45
Step-by-step explanation:
A triangle has 180 degrees interior angle measure. One angle measure 115 so that means the other two angles must add up to 65.
The remaning angles form a ratio of 4:9. This means we must split 65 into a ratio of. 4:9
A ratio partition parts of something. We can add the ratio intergers to find it full length.
4+9=13.
Divide 65/13=5.
Multiply 5x4 and 5x9 serpately.
We get 20 and 45
Below are the choices:
<span>-1/2
0
-1
non
</span>
The exclusions are placed on the variable x for the fraction 4x^2-1/4x+2 is -1/2. Below is the solution,
<span>4x+2 = 0 so 4x=-2 so x=-2/4 wich is -1/2</span>
