Answer:

$6.20 savings.

Step-by-step explanation:

Thus, a product that normally costs $31 with a 20 percent discount will cost you $24.80, and you saved $6.20. You can also calculate how much you save by simply moving the period in 20.00 percent two spaces to the left, and then multiply the result by $31 as follows: $31 x . 20 = $6.20 savings.

Which relationship of angle a is correct? A. Cos(a) = 3/5 B. Cos(a) = 4/3 C. Sin(a) = 3/5 D. Sin(a) = 4/3

kotegsom [21]

The correct answer is C.
Sin(a) = 3/5.

Use the law of similarity the big and small triangles, and then use the definition of sinus of the ankle.

1. Trapezoid KLMN has vertices K(1, 3) , L(3, 1) , M(3, 0) , and N(1, −2) .

chubhunter [2.5K]

Answer:

Step-by-step explanation:

(A) The vertices of the trapezoid KLMN are K(1, 3) , L(3, 1) , M(3, 0) , and N(1, −2)

Now, KL= $\sqrt{(3-1)^{2}+(1-3)^{2}}$ =\sqrt{8}[/tex]

LM= $\sqrt{(3-3)^{2}+(0-1)^{2}}=1$

MN= $\sqrt{(1-3)^{2}+(-2-0)^{2}}=\sqrt{8}$

NK= $\sqrt{(1-1)^{2}+(-2-3)^{2}}=5$

Now, as KL and MN are equal, therefore, KLMN is an isosceles trapezoid.

(B) Since m∠XWY=47°, therefore ∠XWZ=47+47=94° and ∠ZYW=18°, therefore ∠XYZ=36°( as diagonals bisect the angles)

In ΔXWO,

∠XWO+∠WXO+∠WOX=180°(Angle sum property)

∠WXO=43°

Also, from ΔXOY,

∠OXY=72° using the angle sum property.

Therefore, ∠WXY=43+72=115°

Now, sum of all the angles of a quadrilateral is equal to 360°, therefore

∠WXY+∠XYZ+∠YZW+∠ZWX=360°

115°+36°+∠YZW+94°=360°

∠YZW=115°

Therefore,∠WZY=115°

LetM be the mid point of AB, therefore M= $(\frac{-2+4}{2}, \frac{4+3}{2})$

= $(1,\frac{7}{2})$

Also, let N be the mid point of DC, therefore,

N= $(\frac{4-2}{2},\frac{-2-5}{2})$

= $(1,\frac{-7}{2})$

Now, length of the mid segment MN= $\sqrt{(1-1)^{2}+(\frac{7}{2}+\frac{7}{2})^{2}}=\sqrt{0+49}=7 cm$

(D)Given: Kite PQRS, TS=6cm and TP=8cm

Then, From triangle TSP, we have

$(SP)^{2}=(TS)^{2}+(TP)^{2}$

$(SP)^{2}=36+64$

$SP=10cm$

Mean, median, and mode. easy! 19 points!

o-na [289]

The answer is the range. The outliner is anything that “lies outside.” Range is the highest#-lowest#. So 78-28 = 50, which is not close the numbers that occurred most often (in this case, the #s in the 30s).
