I would think (I'm not sure, but it's an idea)
[tex]\frac{x^{2} +2}{x^{2} -1} =\frac{x^{2} -1+1+2}{x^{2} -1}\\\\=\frac{(x^{2}-1) +3}{x^{2} -1}=\frac{x^{2} -1}{x^{2}-1}+\frac{3}{x^{2} -1}\\\\=1+\frac{3}{x^{2} -1}[/tex]
so when x becomes bigger and bigger
the
[tex]\frac{3}{x^{2} -1}[/tex]
will become smaller and smaller
to a point that it's practically 0
so the limit is 1

A box of books weighs 4.10 kg for every meter of it's height. Convert this ratio into pounds per foot.
Answer:
The ratio is k = 2.76 pounds / foot
Step-by-step explanation:
From the question we are told that
For 1 m height => 4.10 kg mass
generally 1 meter = 3.28084 feet
Also
1 kg = 2.20462 pound
4.10 kg = x pounds
So
[tex]x = \frac{4.10 * 2.20462}{1 }[/tex]
=> [tex]x = 9.04 \ pounds[/tex]
So
9.04 pounds = 3.28084 feet
z pounds = 1 foot
So
[tex]z = \frac{ 9.04 * 1 }{ 3.28084}[/tex]
=> z = 2.76 pounds
So the ratio is in pounds per foot is
k = 2.76 pounds / foot

Jean masear is a saw operator in a lumber mill. He works 40 hours a week and earns $630 per week. What is his hourly pay rate
Answer:
[tex]\boxed {\tt \$15.75 \ per \ hour}[/tex]
Step-by-step explanation:
We want to find Jean's hourly pay rate. In other words, his pay per hour.
We can find the pay rate by dividing the money he is paid by the number of hours worked.
[tex]pay \ rate =\frac{money \ paid }{hours}[/tex]
He is paid $630 for 40 hours.
[tex]money \ paid= $630 \\hours= 40\ hours[/tex]
[tex]pay \ rate = \frac{\$630}{40\ hours}[/tex]
Divide.
[tex]pay\ rate = \$15.75 / hour[/tex]
His hourly pay rate is $15.75 per hour.
Find the value of x such that l ⊥ m. A) 10.7 B) 16 C) 46 D) 48
Answer:
B. 16°Step-by-step explanation:
The diagram lacks the appropriate figure. Find the figure attached. If the line I is perpendicular to m, this means that the sum of the given angles will be equal to 90° as shown;
(3x+5)° + 37° = 90°
open the parenthesis
3x+5 + 37° = 90°
3x+42 = 90
subtract 42 from both sides of the equation
3x+42-42 = 90-42
3x = 48
Divide both sides of the resulting equation by 3;
3x/3 = 48/3
x = 16
Hence the value of x is 16°
Suppose PR = 54, solve for QR
We will use the segment addition postulate.
PQ + QR = PR
4x - 1 + 3x - 1 = 54
7x - 2 = 54
7x = 56
x = 8
So QR is 3(8) - 1 or 24 - 1 which is 23.
Answer:
QR is 23
Step-by-step explanation:
PR = 54 Which means:(4x-1)+(3x-1)=54We can solve for x to find what QR is:7x-2 =54 7x=56x=8Plug in x for QR equation:3(8)-1 = 24-1=2323 is the answerFive less than one half of a number is 18.

A certain analog clock runs fast and gains 5 minutes every 8 hours. It was set to show the correct time. What is the shortest interval of time after which the clock will show the correct time again?
Answer:
1152 hours
Step-by-step explanation:
It doesn’t mention that it has AM or PM, so we’re assuming that it’s just the same time, regardless if the clocks actually shows the wrong time in am/pm-wise.
So, if it gains 5 minutes every 8 hours, we have to make see how many 5-minutes that we need to make 12 hours. 12 hours is equal to 720 minutes, so 720/5=144. Since it asks how many hours we need for it to become the same time again, we need to add the fact that it only adds 5 minutes every 8 hours. Henceforth, we need to multiply our answer (144) by 8 hours. 144*8=1152. Your answer is 1152 hours.

The shortest interval of time after which the clock will show the correct time again is 144 hours.
Given that a certain analog clock runs fast and gains 5 minutes every 8 hours, and it was set to show the correct time, to determine what is the shortest interval of time after which the clock will show the correct time again the following calculation must be done:
A clock has a duration of 12 hours, that is, it makes a full turn in that time. Thus, the advance time must be 12 hours for the marked time to be correct.
5 minutes = 1/12 hour 12 hours = 1 hour in advance 12 x 12 = X 144 = X
Therefore, the shortest interval of time after which the clock will show the correct time again is 144 hours.

Answer:
(-4, 7)
Step-by-step explanation:
The x and y coordinates of the midpoint are the average of the x and y coordinates of the endpoints.
-1 = (2 + x) / 2
-2 = 2 + x
x = -4
5 = (3 + y) / 2
10 = 3 + y
y = 7
The coordinates of point S are therefore (-4, 7).

Nash is training for a marathon and decides to train for 26 miles every week. In the first week, the ratio of the number of miles he ran to the number of miles he walked 3:10. In the fifth week the ration ran to walked is 8:5. How many miles did nash run in week 5
Answer:
16 miles
Step-by-step explanation:
From the question given above, the following data were obtained:
Miles per week for training = 26 miles.
In the 5th week:
Ratio of miles ran to miles Walked is 8:5
Thus, we can obtain the miles ran by Nash in the 5th week as follow:
Ratio ran = 8
Ratio walked = 5
Total ratio = 8 + 5 = 13
Miles per week for training = 26 mile
Mile ran in the 5th week = 8/13 × 26
Mile ran in the 5th week = 8 × 2
Mile ran in the 5th week = 16 miles
Therefore, Nash ran 16 miles in the 5th week of training.

Find the equation of the line with slope −2 and that contains the point (−9,−7). Write the equation in the form y=mx+b and identify m and b.
Answer:
m = -2 which is the slope
b = 2 which is the intercept of the line.
Step-by-step explanation:
We have that the line must pass through the following points (-9, -7). These two points are any two of the numerous points that pass through the straight line. We can designate variables to each of these points as shown below
Let us take our [tex]y_1 = -7[/tex] and [tex]x_1 = -9[/tex]
Given the slope as [tex](y-y_1)/(x-x_1)=-2[/tex]
[tex](y--7)/(x--9) = -2[/tex]
[tex](y +7)/(x+9) =-2[/tex]
[tex]y +7 = -2(x+9)[/tex]
[tex]y =-2x+2[/tex]
We are given the form: y=mx+b.
we can compare this with our equation for the line. [tex]y =-2x+2[/tex]
We can see that m = -2 which is the slope and b = 2 which is the intercept of the line.

Sal has 5 balloons. He has 3 red balloons. The rest are blue. Kay has 5 more blue balloons than sal. How many blue balloons does kay have?
Answer:
Kay has 7 blue balloons
Step-by-step explanation:
if Sal has 5 red balloons and 2 blue balloons and Kay has 5 more blue balloons than Sal the Kay has 7 blue balloons
The number of blue balloons does Kay have is 7.
Given that, Sal has 5 balloons. He has 3 red balloons. The rest are blue.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of blue balloons does Kay have be x.
Number of blue balloons Sal have = 5-3=2
The number of blue balloons does Kay have = Kay has 5 more blue balloons than Sal
⇒ x = 2+5 = 7
Therefore, the number of blue balloons does Kay have is 7.

Answer:
2h/ t^2 - 2v/t =g
Step-by-step explanation:
h = vt+1/2 gt^2
Subtract vt from each side
h - vt = vt+1/2 gt^2 -vt
h - vt = 1/2 gt^2
Multiply each side by 2
2( h-vt) = 2 * 1/2 g t^2
2 ( h-vt) = gt^2
Divide each side by t^2
2 ( h-vt) / t^2= gt^2/t^2
2/t^2 (h -vt) = g
Distribute
2h/ t^2 - 2v/t =g
* For his phone service, Goran pays a monthly fee of $24, and he pays an additional $0.06 per minute of use. The least he has been charged in a month is $93.96
*What are the possible numbers of minutes he has used his phone in a month?
*Use m for the number of minutes, and solve your inequality for m.
Answer:
[tex]m \geq 1166[/tex]
Step-by-step explanation:
Given
[tex]Base\ Amount = \$24[/tex]
[tex]Charges = \$0.06[/tex] per minute
[tex]Least\ Monthly\ Charges = \$93.96[/tex]
Required
Determine the possible number of minutes
If for 1 minute, he's charged $0.06;
He'll be charged $0.06m for m minutes
Representing this as an inequality, we have:
[tex]Base\ Amount + m\ Charges \geq\ Least\ Monthly\ Charges[/tex]
[tex]24 + 0.06m \geq 93.96[/tex]
Solve for 0.06m
[tex]0.06m \geq 93.96 - 24[/tex]
[tex]0.06m \geq 69.96[/tex]
Solve for m
[tex]m \geq 69.96/0.06[/tex]
[tex]m \geq 1166[/tex]
This implies that, he's charged for at least 1166 minutes
