A repair bill for your car is $553. The parts cost $265. The labor cost is $48 per hour. Write and solve an equation to find the number of hours of labor spent repairing the car. Record the solution (answer),
Answer:
6 hours
Step-by-step explanation:
Let the labor hours be x.
The bill comprises of parts cost plus labor cost. Labor cost is hours times the cost per hour. Then we have equation:
265 + 48x = 55348x = 553 - 26548x = 288x = 288/48x= 6So the answer is 6 hours.

en un parque de diversiones,el túnel del miedo sube ahasta alcanzar una altura de 50 metros sobre el piso después, cae 65 m hacia un túnel subterráneo ¿cuál es la diferencia entre la elevación del túnel contra la del túnel subterráneo
Responder:
15mExplicación paso a paso:
Deje que el nivel del suelo del parque de atracciones sea cero. Si el túnel del miedo se eleva a una altura de 50 metros sobre el suelo, entonces la distancia desde el nivel del suelo hasta la altura de 50 m sobre el suelo será 50 + 0 = 50 m.
Del mismo modo, si el túnel cae 65 m en un túnel subterráneo, la distancia desde el nivel del suelo hasta la distancia de 65 m bajo tierra será de 65 m.
De ahí la diferencia entre la elevación del túnel y la del túnel subterráneo = 65 m - 50 m = 15 m

find the domain of [tex](4)/(x^2-1)[/tex]
Answer:
See below.
Step-by-step explanation:
We have the rational function:
[tex]\frac{4}{x^2-1}[/tex]
The domains of rational function are the zeros of the denominator. This is because if the denominator equals 0, they the function would be undefined.
Therefore, we need to find the zeros of the denominator. Set the expression in the denominator to zero:
[tex]x^2-1=0[/tex]
Solve for x. Add 1 to both sides:
[tex]x^2=1[/tex]
Take the square root of both sides:
[tex]x=\pm \sqrt1[/tex]
Simplify:
[tex]x=\pm 1[/tex]
So, the domain is all real numbers except for x=-1 and x=1.
In interval notation, this is:
[tex](-\infty,-1)\cup(-1,1)\cup(1,\infty)[/tex]
This is interpreted as all values until -1 not including -1 until all values until 1 not including 1, and then all values there on after.
In set notation, this is:
[tex]\{x|x\in\mathbb{R}, x\neq-1, 1\}[/tex]
Answer:
[tex]\large \boxed{\mathrm{All \ real \ numbers \ except} \ x=-1 \ \mathrm{and} \ x=1}[/tex]
Step-by-step explanation:
[tex]\displaystyle \frac{4}{x^2-1}[/tex]
The domain of a rational function is all the real numbers except the numbers for which the denominator is equal to 0.
Let the denominator equal to 0.
[tex]x^2-1=0[/tex]
Solve for x.
[tex]x^2 =1 \\ \\ \\ x= -1 \ \mathrm{or} \ x=1[/tex]
When x = -1 and x = 1, the function is undefined.
The domain of the function is all real numbers except x = -1 and x = 1.

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. The majority of Earth's atmosphere (78%) is atmosphere nitrogen, making it the largest source of nitrogen. However, atmospheric nitrogen has limited availability for biological use, leading to a scarcity of usable nitrogen in many types of ecosystems.

however, when considering the closest number to 600 when starting with 6, we realise that we can only make 630.
when looking at starting with 5, we can make 590, much closer to 600.
so now, we have deduced it has to become 590

If ∠R measures 18°, q equals 9.5, and p equals 6.0, then which length can be found using the Law of Cosines?
I hope this helps you
If R measures 18°,q equals 9.5 ,p equals 6.0 then we can find the length of PQ which is r using the law of cosines.
What is law of cosines?In trigonometric ratios law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles. Law of cosines is as under:
[tex]c^{2} =a^{2} +b^{2} -2ab cos d[/tex]
where c is the side opposite to the angle given, a,b are the other sides and d is the angle given.
How to find length of triangle?We have been given ∠R=18°, q equals 9.5 , p equals 6.0 then the length r can be calculated as under:
[tex]r^{2} =p^{2} +q^{2} -2pq cos 18[/tex]
r=[tex]\sqrt{p^{2} +q^{2} -2pq cos 18}[/tex]
Hence the length of r is equal to [tex]\sqrt{p^{2} +q^{2} -2pq cos 18}[/tex].

If 26.97 ÷ 6.3 is written in long division form as long division set up where 63 is on the outside of the division symbol and 26970 is on the inside so that the divisor is written as a whole number, where should the decimal point be placed in the dividend?
Answer:
The decimal point should be placed between 9 and 7
i.e
269.70
Step-by-step explanation:
In Long division method, the formula is given as:
Dividend ÷ Divisor = Quotient
We were given
26.97 ÷ 6.3
26.97 = Dividend
6.3 = Divisor
We are told in the question that:
as long division set up where 63 is on the outside of the division symbol and 26970 is on the inside so that the divisor is written as a whole number,
This means, since the Divisor 6.3 is made into an whole number = 63
It means 6.3 was multiplied by 10
6.3 × 10 = 63
In Long division, whatever rule is applied to the Divisor must be applied to the Dividend.
Since 6.3 was multiplied by 10 = 63(whole number), then the dividend must be multiplied by 10
Dividend = 26.97 × 10 = 269.7
Therefore, the place where should the decimal point be placed in the dividend is between 9 and 7
= 269.70
Answer: Between the 9 and the 7

What is the value of X in the equation 1/5X—2/3yequals 30when y equals 15
Answer:
x = 50
Step-by-step explanation:
y = 15
1/5X - 2/3y = 30
1/5x - (2/3 x 15) = 30
1/5x - (10) = 30
1/5x = 30 - 20
1/5x = 10
x = 50

Step-by-step explanation:
g(x) = x − 4
f(x) = 1/x
(g ○ f)(x) = 1/x - 4
(g ○ f)(0) can not be evaluated, because if x = 0, 1/x becomes invalid.

Answer:
5 hourss
Step-by-step explanation:
197-32= 165
165/33
Answer:
5 hours
Step-by-step explanation:
Ralph earned $197 in total but with an initial fee of $32 so,
197 - 32 = 165
$165 is the amount he made from the hourly fee alone. So let's divide the total by the hourly fee.
165 ÷ 33 = 5.
So the job took 5 hours.

30+2k+5k=100
What is k?
Answer:
k = 10
Step-by-step explanation:
30+2k+5k=100
Combine like terms
30 + 7k = 100
Subtract 30 from each side
30+7k-30 = 100-30
7k = 70
Divide each side by 7
7k/7 = 70/7
k = 10
Answer:
k=10
Step-by-step explanation:
We are given the equation:
30+5k+2k=100
We want to find k, therefore we must isolate k on one side of the equation.
First, combine like terms on the left side of the equation. 5k and 2k can be added together.
30+5k+2k=100
30+(5k+2k)=100
30+7k=100
30 is being added to 7k. The inverse of addition is subtraction. Subtract 30 from both sides of the equation.
30-30+7k=100-30
7k= 100-30
7k= 70
k is being multiplied by 7. The inverse of multiplication is division. Divide both sides by 7.
7k/7=70/7
k=70/7
k= 10
The solution to the equation 30+5k+2k=100 is k=10
