Hello, so the equation for the area of a trapezoid is A = (a+b)*(h/2)
In which, a is one of the bases, b is the other base, and h is the height. A is the Area. If you wanna solve for height, rearrange the equation to what h equals.
First divide (a+b) from both sides
A/(a+b) = h/2
Now multiply 2 on both sides
2(A/(a+b)) = h
Now you have it rearranged equal to just h. Plug in the values now.
2(3.9/(4+2.5)) = h
2(3.9/(6.5)) = h
2(.6) = h
1.2 = h
The section is 1.2 centimeters tall.
Answer:
that already is a decimal
Step-by-step explanation:
the fraction form of it is 12 and 1/2
the decimal version of that it 12.5
Nadia's figure has planes of symmetry that include the axis of symmetry. The planes of symmetry of Jon's figure can be described the same way.
In addition, Jon's figure has as a plane of symmetry the plane perpendicular to the axis of symmetry that includes the longest diameter of his torus.
Answer:
Step-by-step explanation: I'm assuming this problem says 56 divided by 7 times 2 in the numerator; OVER 4 to the second power in the denominator. First step would be to multiply 7 times 2, giving you 14. Thus u have 56 divided 14, which is 4. In the denominator, it says 4 to the second power, which is 16. Now u have 4 OVER 16. Now we will reduce the fraction. Both numerator and denominator have a GCF of 4. So we divide top and bottom number by 4. The end result is 1 OVER 4.
