Well, since we know 30 is the unit rate of determining the weight of someone, in order to find the approximate number of quarters of blood in the person's body, all we'll have to do is divide the amount of pounds the person is divided by 30 to figure out the approximate number of quarters of blood in the person's body.So we'll do 120 divided by 30, which is 4.So there are 4 quarters of blood in the 120 pound person.
Good luck with your studies, I hope this helps~!
Length of arc = Cr where C = angle of rotation and r = radius
31 = C*11
C = 31/11 = 2.8 radians to nearest tenth
Check the picture below.
the base of it is one of the triangles, and thus, the sides are just the 3 rectangles.
notice all you have is a 3x5 rectangle, a 5x5 one and a 4x5 rectangle.
get their area, sum them up, and that's the lateral, sides, area of the triangular prism.
(3 · 5) + (5 · 5) + (4 · 5)
If theres on at all then ~ C 6-8 however it seems that theres not one tbh
