Answer:

B) between 20 and 25 minutes

Step-by-step explanation:

First, note that the line from 0 minutes to 5 minutes increases 40 mph. (+40)

Next, note that the line from 5 minutes to 10 minutes increases 10 mph. (+10)

Next, note that the line continues to stay the same from 10 minutes to 20 minutes. (+0)

Now, we get to the last part, which shows a drop from 50 mph to 40 mph (50 - 40 = 10; -10 mph drop)

-------------------------------------------------------------------------------------------------------

We can note that her speed starts at 40 mph, but <em>drops to 10 mph </em>at 5 - 10 minutes. However, note that there is no answer choice for it, and so the next logical choice is the <em>drop of speed from 20 - 25</em>, which is a 10 mph drop.

Is centroid and Circumcentre same?
makvit [3.9K]

No, the centroid and Circumcentre are not same but it is same in equilateral triangle.

The intersection of a triangle's perpendicular bisectors is called the circumcenter.A triangle's circumcenter is a location that is equally spaced from each of its vertices.The centroid of a triangle is the location where its medians connect.

Triangle's centroid is always within it. The centroid of a triangle is its center of gravity in physical terms. If the triangle is evenly distributed around the plane's surface and you want to balance it by supporting it at only one point, you must do it near the center of gravity.Are the circumcenter and centroid at the same location? In the case of an equilateral triangle, they will both be.

Therefore, the centroid and Circumcentre are not same but it is same in equilateral triangle.

Two dice are rolled, find the probability that the sum is less than 13
Alex777 [14]
100% of the rolls would be less than 13. The highest number on one die is 6, so even if you roll 2 dice the sum of both dice will always be lower than 13.
It's a 1:1 probablility.

Which statement describes the graph of the system of equations below?
insens350 [35]
1.5x + 0.2y = 2.68....multiply by 0.3
1.6x + 0.3y = 2.98...multiply by - 0.2
------------------------
0.45x + 0.06y = 0.804 (result of multiplying by 0.3)
- 0.32x - 0.06y = - 0.596 (result of multiplying by - 0.2)
----------------------add
0.13x = 0.208
x = 0.208/0.13
x = 1.6

1.5x + 0.2y = 2.68
1.5(1.6) + 0.2y = 2.68
2.4 + 0.2y = 2.68
0.2y = 2.68 - 2.4
0.2y = 0.28
y = 0.28/0.2
y = 1.4

solution (they intersect at) (1.6,1.4)
