The plane flew over a beacon which is 280 miles from bristol. write down the gmt times when the plane flew over the beacon.
eimsori [14]

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.

A deli offers 2 platters of sandwiches. Platter A has 2 roast beef and 3 turkey sandwiches. Platter B has 3 roast beef and 2 tur
erica [24]

Answer:

2 x+3 y and 3 x+ 2 y

Step-by-step explanation:

Let x represents the number of roast beef and y represents the number of turkey sandwiches.

Let r and t represent cost of the roast beef and sandwich.

Platter A:

Platter A has 2 roast beef and 3 turkey sandwiches. So, equation is 2 x+3 y.

Total cost of the platter = 2 r x+3 t y

Platter B:

Platter B has 3 roast beef and 2 turkey sandwiches. So, equation is 3 x+2 y.

Total cost of the platter = 3 r x+2 t y

So, the two equations are 2 x+3 y and 3 x+ 2 y.
