Adding 56 and 24, one can see that only 80 people responded. Since not all of the random sampling answered, that causes an error.
Answer: 225 square feet
Step-by-step explanation:
We find the area of the 4 triangle and the area of the rectangle and thereafter we add everything together.
Area of triangle 1 = 1/2 base × height
= 1/2 × 12 × 8
=96/2
=48
Area of triangle 2 = area of triangle 1= 48( because the opposite triangle are congruent so they have equal base and height)
Area of triangle 3 = 1/2×base×height
= 1/2 × 6 ×9.5
= 57/2
=28.5
Area of triangle 4=Area of triangle 3 = 57 (the opposite triangle are congruent and so they have the same base and height hence the same area)
Area of the rectangle = length×breadth
=12 × 6 =72
Total surface area = addition of all the areas of the triangles and the rectangle
Total surface area= 48+48+57+57+72 = 225
Therefore, the total surface area is 225 square feet

There are more than one zero i.e. three zeros of the given polynomial.
The zeros are:
<h2>
Step-by-step explanation:</h2>
We are given a function f(x) by:
We know that the zeros of the function f(x) are the possible values of x at which the function is equal to zero.
Hence, when f(x)=0 we have:
Answer:
Five pencils and two marches are worth greater than thirty paper clips.
Step-by-step explanation:
Let 'x' be paper clip.
Let 'y' be a match
and let 'z' be a pencil.
Now, let's write each statement as an equation:
Each paper clip can be traded for three matches:
x = 3y
Each pencil can be traded for six paper clips:
z = 6x
Now, five pencils equals 30 paper clips and two matches equals two thirds papel clips.
Therefore, we can say that Five pencils and two matches equals 30.66 matches. Therefore, five pencils and two marches are worth greater than thirty paper clips.
Hey there!
For this problem, all you need to do is some multiplication:
40 ft per car * 28 cars = 1,120 ft total
30 ft per car * 34 cars = 1,020 ft total
You can see that Train A exceeds the limit, while Train B doesn't.
Hope this helped you out! :-)
