Which choice shows the best estimate of the product 0.52×695

5×600

1/2×700

50×700

1×1,000

1/2×700

Step-by-step explanation:

Here, the given expression is,

Since, we round a number to the nearest number,

Also,

That is, 0.50 is nearer to 0.52 than 5, 50, 1.

So, the best estimation of 0.52 from the given option is

Now, 700 is nearer to 700 than 600 and 1000,

Thus, 700 is the best estimation of 695 from the given options,

Hence, the best estimation of the product 0.52×695 would be 1/2×700.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
