Width (W) = w

Length (L) = 2w + 6

Perimeter = 228

2 (L + W) = 228

L + W = $\frac{228}{2}$

L + W = 114

2w + 6 + w = 114

3w = 114 - 6

3w = 108

w = $\frac{108}{3}$

w = 36

Hence, width is 36 ft and length is (2*36 + 6 = 72 + 6) 78 ft.

P = 2(L + W)
P = 228
L = 2W + 6

228 = 2(2W + 6 + W)
228 = 2(3W + 6)
228 = 6W + 12
228 - 12 = 6W
216 = 6W
216/6 = W
36 = W <=== width is 36 ft

L = 2W + 6
L = 2(36) + 6
L = 72 + 6
L = 78 <=== length is 78 ft

A bank loaned out $21,500 , part of it at the rate of 11% annual interest, and the rest at 10% annual interest. The total intere

Luda [366]

Answer:

The loaned amount at 11 % is $ 19,000

The loaned amount at 10 % is $ 2,500

Step-by-step explanation:

Given as :

The total loan amount = $21,500

The total interest earn = $2,340.00

The rate of interest are 11 % and 10 %

Let The loan amount at 11 % rate = $P

and The loan amount at 10 % rate = $21,500 - $P

Let The loan took for 1 year

Now,<u> From Simple Interest method </u>

Simple Interest = $\dfrac{\textrm Principal\times \textrm Rate\times \textrm Time}{100}$

$SI_1$ = $\dfrac{P_1\times R_1\times \textrm Time}{100}$

Or, $SI_1$ = $\dfrac{P\times 11\times \textrm 1}{100}$

Similarly

$SI_2$ = $\dfrac{21,500 - P\times 10\times \textrm 1}{100}$

∵ $SI_1$ + $SI_2$ = $2,340

Or, $\dfrac{P\times 11\times \textrm 1}{100}$ + $\dfrac{21,500 - P\times 10\times \textrm 1}{100}$ = $2,340

Or, 11 P - 10 P + 215000 = 234000

Or, P = 234000 - 215000

∴ P = $ 19,000

And $21,500 - $ 19,000 = $ 2,500

Hence The loaned amount at 11 % is $ 19,000

And The loaned amount at 10 % is $ 2,500 Answer

To take out terms outside the radical we need to divide the power of the term by the index of the radical; the quotient will be the power of the term outside the radical, and the remainder will be the power of the term inside the radical.
First, lets factor 8:
$8=2 ^{3}$
Now we can divide the power of the term, 3, by the index of the radical 2:
$\frac{3}{2}$ = 1 with a remainder of 1
Next, lets do the same for our second term $x^{7}$ :
$\frac{7}{2}$ = 3 with a remainder of 1
Again, lets do the same for our third term $y^{8}$ :
$\frac{8}{2} =4$ with no remainder, so this term will come out completely.

Finally, lets take our terms out of the radical:
$\sqrt{8x^{7} y^{8} }= \sqrt{ 2^{3} x^{7} y^{8} } =2 x^{3} y^{4} \sqrt{2x}$

We can conclude that the correct answer is the third one.
