Martha is braiding a necklace for her friend. The graph below shows the length of the necklace with respect to the length of time Martha has spent braiding.

Select the equation that represents the proportional relationship shown on the above graph.

A. L = 10t

B. L = 1/10t

C. 20t

D. 1/20t

Step-by-step explanation:

L = 20t

Step-by-step explanation:

The length increases by 20 millimeters per minute

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
