Remy drinks 214 cups of water every 145 hours.
Tcecarenko [31]

Answer:

1  69/145 cups

Step-by-step explanation:

We can use ratio's to solve this problem.  We will put water over time

214 cups           x cups

--------------- = --------------

145 hours        1 hours


Using cross products

214 *1 =145 x

Divide both sides by 125

214/145 = 145x/145

214/145 = x

145 goes into 215 1 time with 69 left over

1 69/145

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)
