Step 1
find the a<span>rea of the first cross section
area1=b1*h/2
b1=8 m
h=10 m
area1=6*10/2------> 30 m</span>²
step 2
find the area of the second cross section
area 2=b2*h/2
b2=12 m
h=10 m
area1=12*10/2------> 60 m²
step 3
find <span>the difference in the areas of the cross sections
</span>difference=60-30------> 30 m²
the answer is
30 m²
You would do 26/60 and turn it into a percentage (43.33333333%)
People may act responsibly to set a good example for others, to impress other people, or to feel proud of their actions.
3/2x-7 Would be the equation
hope this helps ;]
<span>(2a + 2) / (a^2 – 1)
(2(a +1)) / (a^2 - 1)
(2(a + 1)) / (a^2 - 1^2)
(2(a + 1)) / ((a + 1)(a - 1))
2 / a - 1
The answer is: 2/a - 1.</span>
