see the picture in the attached figure
step 1
find the area of rectangle
A=110*43
A=4730 yd²
step 2
find the area of semicircles
we know that two semicircles is equal to one circle
so
Area of the circle=pi*r²
r=43/2
r=21.5 yd
A=pi*21.5²
A=462.25 *pi yd²-------->1,451.465 yd²
total area=area rectangle + area of circle
total area=4,730+1,451.465---------> 6,181.465 yd²
step 3
find the cost
$0.12 per square yard
6,181.465*0.12=$741.78
therefore
the answer is
$741.78
Answer:
Step-by-step explanation:
For a solution to occur y=y so we can say
3x=2x+2 subtract 2x from each side
x=2, since y=3x
y=3(2)
y=6, so the solution exists at the point
(2,6)
I have attached a screenshot with the complete question
Part (1):We are given the prototype used for building the wall with the following dimensions:
long side = 8 in
short side = 5 in
Now, in the wall itself, we want to find the value of the length "a".
This length represents the short side in the prototype used in building the wall.
Therefore:
a = 5 in
Part (2):We are given the prototype used for building the wall with the following dimensions:
long side = 8 in
short side = 5 in
Now, in the wall itself, we want to find the value of the length "b".
This length represents the long side in the prototype used in building the wall.
Therefore:
b = 8 in
Part (3):Looking at Dakota's wall, we can note that its height is formed from three bricks each having the height "b". We have deduced previously that b = 8 in.
Therefore:
height of wall = 3 * b
height of wall = 3 * 8 = 24 in
Part (4):Looking at Dakota's wall, we can note that its length is formed from nine bricks each having a length "a". We have deduced previously that a = 5 in.
Therefore:
length of wall = 9 * a
length of wall = 9 * 5 = 45 in
Hope this helps :)
Answer:
84.7 but don't cheat on exams from now on ;)
40% is the answer because 6/15 = 0.4
