Answer:
1) solve x+1/x = 5
[tex] \frac{x + 1}{x} = 5[/tex]
[tex]x + 1 = 5x[/tex]
[tex]x - 5x = - 1[/tex]
[tex] - 4x = - 1[/tex]
[tex]x = \frac{ -1}{ - 4} [/tex]
[tex]x = \frac{1}{4} [/tex]
2) solve x³+1/x³
[tex]x {}^{3} + \frac{1}{x {}^{3} } [/tex]
substitute x = 1/4 into the expression
[tex]( \frac{1}{4} ) {}^{3} + \frac{1}{( \frac{1}{4}) {}^{3} } [/tex]
[tex] \frac{1}{64} + \frac{1}{ \frac{1}{64} } [/tex]
[tex] \frac{1}{64} + \frac{64 \times 1}{1} [/tex]
[tex] \frac{1}{64} + 64[/tex]
[tex] \frac{4097}{64} \: or \: 64.02[/tex]
Which of the following is equivalent to (8-5) ÷ 2 to the third power?
A. 3/8
B. 19/8
C. 27/8
D. 1/125
The required value is 27/8, which is determined when we compute the expression (8-5) ÷ 2 raised to the third power. Thus, the option (C) is correct.
To find the equivalent expression to (8-5) ÷ 2 raised to the third power, we first simplify the expression inside the parentheses:
(8-5) ÷ 2 = 3 ÷ 2.
Next, we raise this simplified expression to the third power:
(3 ÷ 2)³
To evaluate this, we cube both the numerator and denominator:
(3^3) ÷ (2³) = 27 ÷ 8.
Therefore, the expression (8-5) ÷ 2 to the third power is equivalent to 27/8.
Hence, the correct answer is option C: 27/8.
This means that 27/8 is the value we get when we compute the expression (8-5) ÷ 2 raised to the third power.

Increase 60kg by 33⅓ please help!
Answer:
2000 kg is the answer.
Step-by-step explanation:
We need to increase 60 kg by [tex]33\dfrac{1}{3}[/tex].
The given value is 60 kg. We can find it by finding [tex]33\dfrac{1}{3}[/tex] of 60 kg.
[tex]=60\times \dfrac{100}{3}\\\\=20\times 100\\\\=2000[/tex]
Hence, if we increase 60 kg by [tex]33\dfrac{1}{3}[/tex], we will get 2000 kg.

Maria tenia 6.500kg de patatas. Las envaso en sacos de 25kg y los puso a la venta a 30$ cada uno. Vendio la mitad de los sacos a ese precio y el resto los vendio todos a 2$ menos cada saco. ¿ Cuanto dinero obtuvo?
Responder:
$ 7540
Explicación paso a paso:
Dado que:
Kilogramos totales de papa = 6500
Número de kilogramos por paquete = 25
Precio por paquete = $ 30
La mitad se vendió a $ 30
El resto se vende a ($ 30 - $ 2)
Número total de paquetes de 25 kg:
6500 kg / 25 kg = 260 paquetes
Por lo tanto, paquete total = 260 paquetes
La mitad se vende a $ 30:
(260/2) * 30
130 * $ 30 = $ 3900
Resto vendido a $ 28:
(260 - 130) * $ 28
130 * $ 28 = $ 3640
Cantidad total realizada:
$ (3640 + 3900) = $ 7540

Answer:
$5.61
8.5%
Step-by-step explanation:
Cost of meal = $22
Sales tax = $1.87
How much would the sales tax be on $66 meal
= $66/$22 × $1.87
= 3 × $1.87
= $5.61
What is the tax rate for meals in the city
Tax rate = sales tax / cost of meal × 100
= $1.87/$22 × 100
= 0.085 × 100
= 8.5%
Tax rate = 8.5%

What is the solution of the equation 70 = 1.4y ?
The solution of the equation 70 = 1.4y is 50.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 70 = 1.4y.
Seventy equal to one point four y.
In the given equation the variable is y.
We need to solve for the y.
70 = 1.4y.
Divide both sides by 1.4
70/1.4=y
Seventy divided by one point four equal to y
50=y
The value of y is fifty.

You want to know the opinions of dog owners across America on the issue of establishing a law requiring individuals who own pit bulls to obtain insurance for their dogs. You obtain a list of all registered dog owners and mail a survey to a random sample of 5,000 owners. Of those, 2,389 responded and 22% say that they favor the law. Which of the following statements is true?
Because random sampling is used, we can feel confident the percentage of all dog owners who say they favor insurance for pit bulls is close to 22%.
Because less than half of those who were mailed the survey actually responded, we can feel fairly confident that the actual percentage of all dog owners who say they favor pit bull owners getting insurance for their dog is close to 22%.
We cannot trust these results because the survey was mailed. Only survey results from face-to-face interviews are considered valid.
The results of this survey may be affected by nonresponse bias.

There are 12 runners in marathon and all runners have equal chance of winning. What is the probability that a person may win a bet on the race if he has to correctly select the top 3 runners and
the order they finish in?
a) 1/1320 b) 1/1728
c) 3/1728 d) 1/12
kindly solve it using permutation technique
Answer:
A) 1/1320
Step-by-step explanation:
We know there are 12 runners in the race. Of these 12 people, one of them will get first place. In other words, 12 people have a chance of getting first place. Now there are 11 people remaining to get second place. Since one of the twelfth came first place, there are now 11 runners remaining to get second place. Finally, there are 10 people remaining. Since two of the 12 people came first and second, there are 10 people remaining who can get third place. So if a person was to correctly select the top 3 runners, then he would have a chance of 1/1320. You get this by multiplying 10, 11,12. You get 1320. since you have to pick one combination of 1st,2nd, and 3rd, the answer is A.
What is the approximate area of the shaded sector in the circle shown below? A. 150.8 cm2
B. 6.28 cm2
C. 37.7 cm2
D. 3.14 cm2
Answer:
C
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
(central angle is equal to the measure of the arc, that is 30° )
A = πr² × [tex]\frac{30}{360}[/tex]
= π × 12² × [tex]\frac{1}{12}[/tex]
= 144π ÷ 12
= 12π
≈ 37.7 cm² ( to the nearest tenth )

Step-by-step explanation:
mr brown and his 2 children are going to london by train
an adult ticket costs £24.
an child ticket costs £12
mr brown has a family railcard
family railcard gives : 1/3 off adult tickets
60 percent off child ticket
work out the total cost of the tickets when mr brown uses his family railcard
Answer:
The total cost will be equal to 25.6£
Step-by-step explanation:
In order to solve this question we will have to figure out the cost of the adult ticket and the children tickets when the railcard is used. For this we do the following.....
Let "a" be the cost of the adult ticket after using the railcard
Let "b" be the cost of the children ticket after using the railcard.
a = 24£ - (24£ x [tex]\frac{1}{3}[/tex]) = 24£ - 8£ = 16£
b = 12£ - (12£ x [tex]\frac{6}{10}[/tex]) = 12£ - 7.2£ = 4.8£
Now the total cost will be equal to the sum of an adult ticket and two children tickets after the railcard is used, so .....
Total cost = a + 2b = 16£ + 2(4.8£)= 16£ + 9.6£ = 25.6£

8. Find the x and y intercepts. 6x + 12y = 24
Answer:
x - intercept: 4
y - intercept: 2
Step-by-step explanation:
The way you find the x-intereceppt is to pretend that the 12y isnt there. Therfore making the equation 6x=24. Then 24 divided by 6 equals 4.
The same thing but for the y-intercpt. Take away the 6x making the equation 12y=24. 24 divivded by 12 equals 2.
