Find the length of midsegment YZ in trapezoid ABCD when A(-5,-6) B(-6,-2) C(-4,0) and D(3,2)

Luda [366]

Answer:

Option C

Step-by-step explanation:

Since, Y and Z are the midpoints of sides AB and CD of the given trapezoid.

Segment YZ will the midsegment of trapezoid ABCD.

By the theorem of midsegment,

m(YZ) = $\frac{1}{2}(AD+BC)$

By using expression for the length of a segment between two points,

Length of a segment = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between two points A(-5, -6) and D(3, 2),

AD = $\sqrt{(3+5)^2+(2+6)^2}$

AD = $\sqrt{64+64}$

AD = $\sqrt{128}$

AD = $8\sqrt{2}$

Distance between B(-6, -2) and C(-4, 0)

BC = $\sqrt{(-6+4)^2+(-2-0)^2}$

BC = $\sqrt{8}$

BC = $2\sqrt{2}$

Therefore, m(YZ) = $\frac{1}{2}(8\sqrt{2}+2\sqrt{2})$

= $\frac{1}{2} (10\sqrt{2})$

= $5\sqrt{2}$

Option C will be the answer.

C = 5/9 (F - 32) <br><br> solve for F

Tpy6a [65]

C = 5/9(F-32) /*(9/5)
(9/5)* C =F-32
F =(9/5)C +32

Charles has 3/5 the amount of money Di has. How much money does charles have if Di has $6 more than him?

DaniilM [7]

Charles = Di multiplied by 3/5
Charles = Di minus 6
x multiplied by .6 = x - 6
15 multiplied by .6 = 15 - 6

Di = 15
Charles = 9

Pinto beans cost $4.59 per bag how much wood three eights of a bag cost

N76 [4]

$\bf \begin{array}{ccll}
\stackrel{beans}{price}&bag\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
4.59&1\\\\
p&\frac{3}{8}
\end{array}\implies \cfrac{4.59}{p}=\cfrac{1}{\frac{3}{8}}\implies \cfrac{4.59}{p}=\cfrac{\frac{1}{1}}{\frac{3}{8}}\implies \cfrac{4.59}{p}=\cfrac{1}{1}\cdot \cfrac{8}{3}
\\\\\\
\cfrac{4.59}{p}=\cfrac{8}{3}\implies \cfrac{4.59\cdot 3}{8}=p$
