While correcting his math homework, a student notices his eraser is shaped like a parallelogram. He sketches it as parallelogram ABCD. One of the four sides of the parallelogram measures 5cm, and a second side measures 1.25cm. What is the perimeter of ABCD? A) 5 B)6.25 C)7.5 D)12.5 E)20

step-by-step explanation:

what does 'mandy have ben 780 bottle caps. ' mean?

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

20 feet per second
