  1. To solve this, we need to find the length of side FE using the Pythagorean Theorem, a^2 + b^2 = c^2.  Sides FD and DE are both 3 units long.
    3^2 + 3^2 = c^2
    9 + 9 = c^2
    18 = c^2
    sqrt18 = sqrtc^2
    4.2 ≈ c
    Now, we will add all three sides.  4.2 + 3 + 3 = 10.2.  The correct answer is C, 10.2 units.

  2. That symbol represents a source of DC, usually a battery.

    The zig-zag line represents a resistor, and the two little circles
    connected by a short line represent a switch in the closed position.,

  3. A) A source of electrical energy.

    Explanation:

    The Symbol of two long lines, two short lines represents and, a positive and negative sign is a voltage source, which is a two-terminal device capable of maintaining a constant voltage.

    The voltage generates an electric field, which makes the electrons inside the conductive cables to move along the circuit from the positive sign to the negative sign.

  5. Using elimination method to solve the y-value
    2x + 3y = 20
    -2x + y   = 4
    + (add)
             4y = 24

    The first mistake is when she added 20 + 4, it's supposed to be 24 not 16

    4y = 24
      y = 24/4
      y = 6

    Using subtitution method to solve the x-value
    2x + 3y = 20
    2x + 3(6) = 20
    2x + 18 = 20
    2x = 2
    x = 1

    The correct solution to the system is (1,6)

  6. answer:

    107.1 yards squared

    Step-by-step explanation:

    Area of triangle=base*height/2

    34 yds*6.3 yds/2=107.1

    A=107.1 yards squared

  7. Since the diamater of the two half circles is 5 ft. the area of those combined would be: pi * r ^2 = pi * 2.5^2 = 19.6349540849 (almost 20)

    And the area of the rectangle would be 5 * 15 = 75

    So.. the approximate area of the figure would be 75 + 20 = 95
