Should the line of best-fit travel through the origin of the graph . Explain your reasoning

Answers

Answer 1

Answer: No because if it does then you had no human error and based on what your graphing it is very unlikely that when you have zero at your x axis you will also reasonably be at zero on your y axis! Hope this helps you

Given AABC. m LA= 39°
MLB=104°
AC= 20cm
mLC=
AB =
CB -

Answers

Answer:

∠C = 37° ,

AB = 26.54 cm ,

BC= 33.27 cm

Step-by-step explanation:

Given that in triangle ABC

∠A = 39° AC = 20 cm

∠B = 104°

∵ sum of all the three angles of triangle = 180°

So, ∠C = 180° - ( ∠A + ∠B)

∠C = 180° - (39° + 104°)

∠C = 37°

Now Tan 37° = $(AC)/(AB)$

Or, AB = $(20)/(tan 37°)$

So, AB = 26.54 cm

Again, Sin 37° = $(AC)/(BC)$

So, BC = $(20)/(sin 37°)$

Or, BC = $(20)/(0.601)$

∴ BC= 33.27 cm

Hence ∠C = 37° , AB = 26.54 cm , BC= 33.27 cm Answer

You play video games online. When you sign up with the game site, you get 400 points. You earn 50 more points for each hour that you play. How many hours do you have to play to get to 1,000 points?

Answers

The answer is 12 but the way you get it is you subtract 400 from 1000 which gives you 600 then you divide 600 by 50 to get 12. So it looks like this 1000-400= 600, 600/50=12. Hope this helps. :)

1000-400=600 points left
600 / 50 = 12
So you would have to play for 12 hours to reach 1000 points

The perimeter of Ryan's room is 576 inches. How many yards is the perimeter of Ryan's room?

Answers

Here, we need to convert from inches to yards.

36 inches = 1 yard

576/30 = 19.2

The yards in Ryan's room is 19.2 yards.

Final answer: 19.2 yards

Because we have the formula yd =in * 0.027778;
576 * 0.027778 = 16 yards
