In nadias dvd collection she has 8 action dvds and 12 comedy dvds, romance dvds, and 3 science dvds what percent of nadias dvd collection are comedies?

answer:

82.24 or 44.56 square feet (depending on picture)

step-by-step explanation:

to find the area of a rectangular window and semi circle on top use the formulas a=b*h and . add the values from these two formulas and this is the area of the whole shape. without the picture, its difficult to know what the measurements for the semi-circle are. there are two likely options:

option #1:

the rectangular window has base of 8 feet and a height of 4 feet. this means the semi-circle has a diameter of 8 feet and a radius of 4 feet. the formulas are:

a=b*h=8*4 = 32

[tex]a= \pi r^2= \pi (4)^2=50.24/tex]

the area together is 32 + 50.24 = 82.24 square feet.

option #2:

the rectangular window has base of 4 feet and a height of 8 feet. this means the semi-circle has a diameter of 4 feet and a radius of 2 feet. the formulas are:

a=b*h=4*8 = 32

[tex]a= \pi r^2= \pi (2)^2=12.56/tex]

the area together is 32 + 12.56 = 44.56 square feet.

answer:

  3x - 2y = 31

step-by-step explanation:

the 2-point form of the equation for a line is useful for this. for points (x1, y1) and (x2, y2), it tells you

  y = (y2 -y1)/(x2 -x1)·(x -x1) +y1

substituting the given point values, we get

  y = (4 ))/(13 -5)·(x -5) +(-8)

  y = (12/8)(x -5) - 8 = (3/2)(x -5) -8

multiplying by 2 gives

  2y = 3(x -5) -16

  2y = 3x -15 -16

adding 31-2y changes this to standard form:

  3x -2y = 31
