The first step in solving this problem is to compute for the
area of the rectangular wall. The formula in computing the area of a rectangle
is:
A = LW
Substituting the given measurements in the problem to the
formula:
A = 13 (12)
A = 156
Therefore, the area of the wall is 156 square feet. To compute
the wallpaper cost of the wall, you have to multiply the cost per square foot
to the total area.
$8 per square foot x 156 square feet = $1,248
Therefore, the wallpaper cost for the wall is $1,248
Answer:
The midpoint is (-4.5,.5)
Step-by-step explanation:
To find the x coordinate, add the x coordinate of the ends and divide by 2
(-1+-8)/2 = -9/2 = -4.5
To find the y coordinate, add the y coordinate of the ends and divide by 2
(5+-4)/2 = 1/2 =.5
The midpoint is (-4.5,.5)
Answer: 1/2 is the value b such that (b)^1 = 1/2, the fraction the isotope decays in one year.
