The step of Talia that's incorrect is: C. step 3 because the slope ratio she calculated is incorrect.
<h3>What is the Slope?</h3>
The slope of a line (m) = rise/run = change in y / change in x.
Calculating the slope using two points on the line, (2, 5) and (1, 3), we should have:
Slope (m) = (5 - 3)/(2 - 1)
Slope (m) = (2)/(1)
Slope (m) = 2
This shows that the ratio of the slope calculated by Talia was wrong. The step that is incorrect is: C. Step 3

Answer:

Step-by-step explanation:
We have the angle in standard post has a sine ratio of

This means the opposite side length of the corresponding right triangle is 9 units and the hypotenuse is 41 units.
Using Pythagoras Theorem, the adjacent side length can be found using:

This implies that:




The cosine ratio is adjacent over hypotenuse.

Since we are in the second quadrant, the cosine ratio is negative;

404 error: graph not found
anyway, the graph was not included. since the sleep time was included, I will assume that the circle graph is worth 24 hours
all we need to do is to convert the percentages to fractions and multiply that by 24 to find out how many hours per activity
percent means parts out of 100 so x%=x/100
so we have

Free Time
School=25%
25%=25/100=1/4
1/4 times 24=6
School: 6 hours
Eating=10%
10%=10/100=1/10
1/10 times 24=2.4
Eating: 2.4 hours
Sleep=40%
40%=40/100=4/10=2/5
2/5 times 24=48/5=9.6
Sleep: 9.6 hours
Homework=10%
10%=10/100=1/10
1/10 times 24=2.4
Homework: 2.4 hours
Free Time=15%
15%=15/100=3/30
3/20 times 24=72/20=36/10=3.6

Answer:
-4/3, -0.4, 0.8,
, 
Step-by-step explanation:
-4/3 equals -1.333(repeating)
\sqrt 2 = 1.4
\sqrt 11 = 3.3
Answer:
28
Step-by-step explanation:
It helps to plot the points on a graph. It is easy to see that three of the sides are of length 6, and the remaining two are the hypotenuse of a 3-4-5 triangle, hence length 5.
3×6 +2×5 = 28
The perimeter of this polygon is 28 units.
