According to graph, GMT time when the plane flew over the beacon was 9:24.
While looking closely at the graph on x axis , one will notice that each hour is divided into 5 parts and hence each part has 12 minutes. looking at y axis, one may find that each part on y axis resembles 20miles. Hence at 280 miles away from Bristol, The GMT time is 9:24.
<h3>What is a graph?</h3>
- In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.
- The relationships between two or more items are frequently represented by the points on a graph.
- The study of graphs, which are mathematical constructions used to represent pairwise relationships between things, is known as graph theory in mathematics. Vertices (also known as nodes or points) make up a graph in this sense, which are connected by edges (also called links or lines).
- Undirected graphs, in which edges connect two vertices symmetrically, are distinguished from directed graphs, in which edges connect two vertices asymmetrically. One of the main topics of study in discrete mathematics is graphs.

Very nice handwriting but the math and English are confusing.
Let's assume we're told
The subscript is important.
I think we're told the similar sum with 11 gives the smallest possible value for the sum. This is a rather cagey way of telling us 11 is the mean of the nine points. The mean is the number which minimizes the sum of squared deviations.
If 11 is the mean, the sum of the points is 9(11)=99.
Answer: 1080
In a 30-60-90 triangle:
the side opposite of the 30 degree angle has a length of "b"
the side opposite of the 60 degree angle has a length of "b√3"
the side opposite of the 90 degree angle has a length of "2b"
The given value of 8 is opposite of the 90 degree angle, so 8 = 2b → 4 = b
Now, plug in 4 for b to determine the lengths of the other sides.
s is the side opposite of the 30 degree angle which has a length of "b"
so, s is 4
q is the side opposite of the 60 degree angle which has a length of "b√3"
so, q is 4√3
Answer: F
Here is the graph, the points are (-1,-5) (0,0) (1,5) (2,10)
Answer:
3:2
Step-by-step explanation:
Triangles ABC and PMN are similar. This is evident from the marks identifying equal angles.
The ratio of the two longest sides is 20:30, or 2:3.
The ratio of the two shortest sides is 12:18, or 2:3.
Finally, the ratio of the two sides of intermediate length is 16:24, or 2:3.
The scale factor of the alrger triangle to the smaller triangle is 3:2.
