Answer:

12

Step-by-step explanation:

We know that AD=BC and that AB=CD. We also know the perimeter of the rectangle ABCD to be 54 units.

From this, we can add up the sides which will be equal to 54 units.

AD+BC+AB+CD=54

2x+2x+3x-3+3x-3=54

10x=60

x=6

Since we are trying to find the length of side BC we substitute this value back into 2x.

BC=2x =2*6=12

Therefore, the length of BC is 12 units.

Answer:

h = 0.64 ft

Step-by-step explanation:

s =  \frac{14 + 12 + 6}{2}  =  \frac{32}{2}  = 16 \: ft \\  \\ A =  \sqrt{(s - 14)(s - 12)(s - 6)}  \\  \\ A =  \sqrt{(16 - 14)(16 - 12)(16 - 6)}  \\  \\ A =  \sqrt{(2)(4)(10)}  \\  \\ A =  \sqrt{80}  \\  \\ A =  8.94427191\\  \\ A  \approx  8.94 \:  {ft}^{2}

A = 14h

8.94427191 = 14h

h = 8.94/14

h = 0.638571429

h = 0.64 ft

A total of ​$24,000 is to be invested in stocks and bonds. If the amount invested in bonds is three times that invested in​ stoc
Ilya [14]

Answer:

  • bonds: $18,000
  • stocks: $6,000

Step-by-step explanation:

You have a total of $24,000 invested in stocks and bonds in the ratio 1 : 3. You want to know the amount invested in each category.

<h3>Ratio</h3>

Recognizing that the total number of ratio units is 1+3 = 4, and that total represents $24,000, we see that each ratio unit represents $24,000/4 = $6,000.

Multiplying the ratio by $6,000, we see the investment amounts are ...

  stocks : bonds = 1 : 3 = $6,000 : $18,000

$6,000 is invested in stocks; $18,000 is invested in bonds.
