If the mass of your roommate is 150 lbm, what is his or her weight (lbf)?

4830 lbf

Step-by-step explanation:

mass of the roommate = 150 lbm

here lbm means pound

hence the mass of the roommate = 150 pounds

we know that  lbf = lbm×32.2       ( value of g in British unit 32.2 ft/s^2)

lbf= 150×32.2= 4830 lbf

hence the weight of the roommate = 4830 lbf

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.
