Anna007 [38]2 years ago
7 0

Answer:

To do this you must first determine what fraction of the circle is represented by the central angle 30°. Since there are 360° in a full circle, you can find the fraction of a circle by simplifying . The sector represents of the circle. To find the arc length, you now need to find the circumference of the entire circle.

A student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 34
VikaD [51]

Answer:

41.6 centimeters

Step-by-step explanation:

The right triangle formula: c^2 = a^2 + b^2

                                  c is the hypotenuse side of the triangle

                                  a and b are the legs of the triangle.    

 Find the hypotenuse :   c^2 = (24)^2 + (34)^2

                                          c = square root of (  (24)^2 + (34)^2)

                                          c = square root of ( 576 + 1,156)

                                          c = 41.6173

wolverine [178]

Answer:

Answer:

4.8 gigabytes

Step-by-step explanation:

Let the number of gigabytes of data = x

Xavier pays a flat cost of $44 per month and $3 per gigabyte. He wants to keep his bill at $58.40 per month.

The above expression above is represented by the equation:

$44 + $3 × x = $58.40

44 + 3x = 58.40

Solving for x

Subtract 44 from both sides

44 - 44 + 3x = 58.40 - 44

3x = 14.4

x = 14.4/3

x = 4.8 gigabytes

What is the area of the trapezoid shown? trapezoid A = ______ units²?
notka56 [123]

Answer:

74.1 units²

Step-by-step explanation:

Area of the trapezoid shown = ½×(AD + BC)×BE

Use distance formula, d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} to find AD, BC, and BE.

✍️Distance between A(-9, 4) and D(9, 1):

AD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(9 -(-9))^2 + (1 - 4)^2}

= \sqrt{(18)^2 + (-3)^2}

= \sqrt{(324 + 9} = \sqrt{333}

AD = 18.2 units (nearest tenth)

✍️Distance between B(-4, -3) and C(2, -4):

BC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(2 -(-4))^2 + (-4 -(-3))^2}

= \sqrt{(6)^2 + (-1)^2}

= \sqrt{(36 + 1} = \sqrt{37}

BC = 6.1 units (nearest tenth)

✍️Distance between B(-4, -3) and E(-3, 3):

BE = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(-3 -(-4))^2 + (3 -(-3))^2}

= \sqrt{(1)^2 + (6)^2}

= \sqrt{(1 + 36} = \sqrt{37}

BE = 6.1 units (nearest tenth)

✔️Area of the trapezoid:

Area = ½×(AD + BC)×BE

Plug in the values into the formula

Area = ½×(18.2 + 6.1)×6.1

Area = ½×(24.3)×6.1

Area = 74.115 ≈ 74.1 units² (nearest tenth)
