Consider,
[tex]\rm \longmapsto\:\dfrac{ \sqrt{7} + i \sqrt{3} }{ \sqrt{7} - i \sqrt{3}} + \dfrac{ \sqrt{7} - i \sqrt{3} }{ \sqrt{7} + i \sqrt{3} } [/tex]
On taking LCM, we get
[tex]\rm \: = \: \dfrac{ {( \sqrt{7} + i \sqrt{3})}^{2} + {( \sqrt{7} - i \sqrt{3})}^{2} }{( \sqrt{7} + i \sqrt{3})( \sqrt{7} - i \sqrt{3})} [/tex]
We know,
[tex] \purple{\rm \longmapsto\:\boxed{\tt{ {(x + y)}^{2} + {(x - y)}^{2} = 2( {x}^{2} + {y}^{2})}}} \\ [/tex]
and
[tex] \purple{\rm \longmapsto\:\boxed{\tt{ (x + y)(x - y) = {x}^{2} - {y}^{2} \: }}} \\ [/tex]
So, using these Identities, we get
[tex]\rm \: = \: \dfrac{2\bigg[ {( \sqrt{7})}^{2} + {(i \sqrt{3}) }^{2} \bigg]}{ {( \sqrt{7}) }^{2} - {(i \sqrt{3})}^{2} } [/tex]
[tex]\rm \: = \: \dfrac{2(7 + 3 {i}^{2})}{7 - {3i}^{2} } [/tex]
We know,

So, using this, we get

Hence,

69 total planks divided by 5 for each bookshelf.
That would be 69÷5=13.8
Seeing as you can't make .8 of a shelf, those planks would just be extra.

Tom makes $249.25 in 5 days. How much does he make in 4 days?
Answer:
$199.4 in four days
$49.85 in one day
Step-by-step explanation:
249.25 / 5 =49.85
49.85 x 4 = 199.4
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The amount that Tom makes in 4 days is $199.4.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Tom makes $249.25 in 5 days. Therefore, the amount that Tom makes in a day is,
Amount Tom makes in a day = $249.25 / 5 days
= $49.85 per day
The amount of money that Tom can make in 4 days is,
Amount = $49.85 per day × 4 days
= $199.4
Hence, the amount that Tom makes in 4 days is $199.4.

Hansen thinks his pet goldfish, Finn, might be lonely. So, Hansen buys another goldfish to keep Finn company. He also buys a large 10-gallon tank so the two fish can swim together. If Finn currently lives in a 2-quart fish bowl, how many times bigger is his new tank than his old bowl?
Answer:
Well, 1 gallon is 4 quarts so if Finn lives in a ½ Gallon tank divide 10 by 0.5 and you get 20, so his new tank is 20 times bigger than his old bowl.

Jaylo bought a television priced at $349. She received a 20% discount and paid a 7% sales tax. What is the total price of the television? A. $74.69 B. $298.74 C. $348.87 D. $448.12
Answer:
B
Step-by-step explanation:
349 ---100%
x ------ 20%
x= (349×20)÷100
x=69.8
349-69.8=279.2
279.2 ---100%
x-----7%
x=(279.2×7)÷100
x=19.54
Final result
279.2+19.54=298.74
And final result is B
The total price of the television is B. $297.74
Given that,
Jaylo bought a television priced at $349. She received a 20% discount and paid a 7% sales tax.Based on the above information, the calculation is as follows:
[tex]= (\$349 \times (1- 0.20) + \$349 \times (1- 0.20) \times 0.07)\\\\= \$279.20 + \$19.544[/tex]

two complementary angles are in a ration of 2 3 find the measure of each angle
A complementary angle is 90 degrees. The ratio is 2:3 so the equation would be:
2x+3x=90
5x=90
x=18
One of the angles would be 2(18) or 36 degrees and the other angle would be 3(18) or 54 degrees.
36+54 is equal to 90 degrees so it checks out.
¿Cuál es el perímetro de un rectángulo, si su diagonal mide 37 m y el ancho mide 12 m ?
Answer:
94 m
Step-by-step explanation:
Sea L definido como
L = la longitud del rectángulo, en unidades de metros.
Así, según el Teorema de Pitágoras, tenemos que
12 ^ 2 + L ^ 2 = 37 ^ 2
L ^ 2 = 37 ^ 2-12 ^ 2
L ^ 2 = (37 - 12) (37 + 12)
L ^ 2 = 25 * 49, de modo que
L = 5 * 7 = 35.
Por lo tanto, el perímetro = 2L + 2W = 2 (L + W) = 2 (35 + 12) = 2 (47) = 94 m
