Mrs smalls is sewing a sweater for her grandson. it took her 1/5 hour to sew 2/7 inch. how fast is mrs smalls sewing speed in inches per hour

1.4285 inches/hour

Step-by-step explanation: 1/5 of an hour is equal to 20%, or 0.2 hours. 2/7 inch is equal to 0.2857 inches, approximately. If she sews 0,2857 inches in 0,2 hours, we can cross multiply the values we want to discover:

x inches  -  1 hour

0.2857 inches - 0.2 hours

Then, 1.4285 inches are sewed in one hour.

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5

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.
