2640/825=3.2
There is need 4 gallons to cover 2640 sq ft.
80% of the fourth gallon can be used for other purposes after painting.
This is a triangle prism, the base is a square and the four sides are equal triangles.
To find the surface area you need to first find the areas of the triangles, then the square, in the end you have to add them together.
Since we know the area of a triangle is 1/2bh we know that one if the triangle in the figure is
9*16/2=72(in^2)
there are four of these so we multiply it by 4
4*72=288(in^2 aka squared inches)
Then we need to find the area of the square. side * side=9*9=81 (in^2)
Add them together we get the surface area.
288+81=369 (in^2)
Point slope
the equaiton of a line passing through the point (x1,y1) and having a slope of m is
y-y1=m(x-x1)
and the slope between 2 points, (x1,y1) and (x2,y2) is (y1-y2)/(x1-x2)
so
find slope first
(-2,-5)
(2,3)
slope=(-5-3)/(-2-2)=-8/-4=-2/-1=2
m=2
pointn is (2,3) and (-2,-5)
the answer is
y-3=2(x-2) or
y+5=2(x+2)
Answer:
<em>The amount of rabbit after 1 year will be </em><em>320</em><em>.</em>
Step-by-step explanation:
A gardener brought 5 rabbits, after 2 months rabbits became 10.
The growth continues on the same ratio.
This represents a geometric sequence with 1st term as 5 and common ratio as 2.
As we have to find the amount of rabbit after 1 year, so the we have to find 
th term. As the time difference between each counting is 2 months, so we divided 1 year or 12 months of time by 2.
nth term in a G.P is,
Putting the values,
