Answer:
Step-by-step explanation:
From the graphs attached,
Let the coordinates of the two points given on the black line in the first graph are (-4, 2) and (-1, 10).
When these points have been rotated by 90° about the origin,
Rule for the rotation will be,
(x, y) → (y, -x)
Therefore, coordinates of the image points will be,
(-4, 2) → (2, 4)
(-1, 10) → (10, 1)
Therefore, red line given given in graph (1) and black line (After rotaion of 90° clockwise) in graph (2) will be same.
I think the relationship between the weight of a stack of standard 8.5x11 copier paper vs number of sheets of paper is proportional because :
Let us assume here, in this situation that each page has the same weight so if i want to find the weight of the complete stack, i will multiply the number of sheets of paper by the weight of a single sheet of paper.
Answer:
13. 7=108 degrees
14. 8=70 degrees
15. 8=38 degrees
16. 6=73 degrees
17. 6=80 degrees
Step-by-step explanation:
13. If 6=72 what is 7
Angles on a straight line add to 180
180-72=108 degrees
14. If 9 = 110 what of 8
Angles on a straight line add to 180
180-110=70 degrees
15. If 7 =142 what of 8
Angles on a straight line add to 180
180-142=38 degrees
16. If 9 =107 what of 6
Angles on a straight line add to 180
180-107=73 degrees
17. If 8=80 what of 6
Direct opposite Angel's are equal so 6 =80 degrees
Answer:
17 pencils
Step-by-step explanation:
Assume that cup C holds x pencils. In this case, cup A holds x + 1 pencils, and cup B holds x + 2 pencils. We know that all of the cups together hold 48 pencils. If we add what we got together, we would get x + x + 1 + x + 2 = 48. 2x + 1 + x + 2 = 48. 2x + x + 1 + 2 = 48. 3x + 1 + 2 = 48. 3x + 3 = 48. 3x = 48 - 3. 3x = 45. x = 45 / 3. x = 15. Now, we know that cup C holds 15 pencils, and from here, we can find the number of pencils in cup B by adding 2 to 15 and getting 17, and that would be your answer.

The percentage error is 11.1%
<h3>What is percentage error?</h3>
Percentage error is simply the difference between the exact and the estimated values as a percentage
The given parameters are:
The percentage error is then calculated as:
Evaluate the difference
So, we have:
Hence, the percentage error is 11.1%
