To find the height, you will utilize the formula for area of a trapezoid. A = h(b1 +b2)/2. h is the height, b1 is the the first base, and b2 is the second base. When you substitute the information given to us in the question, the equation that needs solved is 37.4 = h(6.4 + 12.3)/2. You should multiply both sides by 2 to undo the dividing by 2. This gives you 74.8 = h (18.7). To solve for the height, divide both sides by 18.7. This gives us a cross sections height of 4 meters. This is the answer!
Hi there, well the opposite of subtraction is addition. So we are going to add 2/5 by 1/5. 2/5+1/5=3/5, to check if we are right we do 3/5-1/5 and that would equal 1/5. Therefore, X=3/5
Answer:
1040 feet
Step-by-step explanation:
The first thing is to add the two lengths of the semicircle to make it one whole circle. Then, you add the two lengths of the rectangle which is the measurements in the middle part.
Done! The answer gives you: 1040 ft
The answer is 1/7 and can be explained mathematically in the picture
