Answer:

10.30

Step-by-step explanation:

Pythagorean Theorem is a^{2} + b^{2} = c^{2}.  The short leg(a) is 5 units long and the long leg(b) is 9 units long.  CD is the hypotenuse, the longest side (c).

5^{2} +9^{2} =c^{2}

25+81=c^{2}

106=c^{2}

\sqrt{106} = \sqrt{c^{2} }

10.29563014 = c

Rounded to the nearest hundredth, 10.30

To check this is correct, the hypotenuse is the longest side, and 10.30 is longer than 5 and 9.

Mary ravi and Alan have a total of $62 in their wallets. Mary has $6 more than Ravi. Alan has 2 times what Mary has. How much do
mixas84 [53]

Answer:

Marry = $17

Ravi = $11

Alan = $34

Step-by-step explanation:

Let us assume

Mary be X

Ravi be Y

Alan be Z

So, the equation in total is

X + Y + Z = 62

It is given that

X = Y + 6

Z = 2X

Now we put the Z value in the total equation, so it would be

X + Y + 2X = 62

3X + Y = 62  .................................... (1)

And can we write

X = Y + 6

X - Y = 6 ................................. (2)

Now substitution these two equations,

3X + Y = 62

X - Y = 6

2X = 68

X = $17

So, Z = 2 × 17 = $34

And, Y

$17 + Y + $34 = $62

So, Y = $11

The perimeter of △CDE is 55 cm. A rhombus DMFN is inscribed in this triangle so that vertices M, F, and N lie on the sides CD ,
ivanzaharov [21]

Answer:

  CD = 14 cm; DE = 21 cm

Step-by-step explanation:

The perimeter is the sum of side lengths (in centimeters), so ...

  CD + DE + CF + EF = 55

  CD + DE + 8 + 12 = 55 . . . . . . . substittute for CF and EF

  CD + DE = 35 . . . . . . . . . . . . . . subtract 20

___

The segment DF is a diagonal of the rhombus, so bisects angle D. That angle bisector divides ΔCDE into segments that are proportional. That is, ...

  CD/DE = CF/EF = 8/12 = 2/3

___

So, we have two segments whose sum is 35 (cm) and whose ratio is 2 : 3. The total of "ratio units is 2+3=5, so each must stand for a length unit of 35/5 = 7 (cm). The sides are ...

  CD = 2·7 cm = 14 cm

  DE = 3·7 cm = 21 cm

<em>Check</em>

  CD + DE = (14 +21) cm = 35 cm . . . . . matches requirements
