Subtract the rational expression 1/x^2-x-6 - x/x+2.
Answer:
Step-by-step explanation:
x² - x -6 = x² + 2x - 3x - 3*2
=x(x + 2) - 3(x + 2)
= (x + 2 )(x - 3)
[tex]\frac{1}{x^{2}-x-6}+\frac{x}{x+2}=\frac{1}{(x +2 )(x - 3)}-\frac{x}{x + 2}\\[/tex]
[tex]= \frac{1}{(x+2)(x-3)}-\frac{x(x-3)}{(x+2)(x-3)}\\\\=\frac{1-x(x-3)}{(x+2)(x-3)}\\\\=\frac{1-x^{2}+3x}{(x+2)(x-3)}\\\\[/tex]

Nancy bought a mobile phone marked at 720$ at a discount of 20 percent and she had to pay 5 percent tax. If Nancy had to put 20 percent of what she had to pay including tax as a deposit, how much money did she have to pay for the deposit?
Answer:
$120.96
Step-by-step explanation:
If there is a 20% discount, she would pay 80% of the price
o.80 x $720 = $576
If there is a tax of 5%, the price she pays increases by 5%
1.05 x 576 = 604.80
If she pays 20% deposit, she would pay
0.2 x 604.80 = $120.96

Deborah spent $70 on food and clothes. She spent $26 more on clothes than on food. On your worksheet, solve the question and write your answer below. How much did she spend on food and how much did she spend on clothes?
Answer:
the spent on food would be $23
And for clothes it would be = $23 + $24 = $47
Step-by-step explanation:
Let us assume the food be x
So for clothes it would be x + $24
And, the total spent on food and clothes is $70
So the equation is
x + x + $24 - $70
2x = $70 - $24
2x = $46
x = $23
So, the spent on food would be $23
And for clothes it would be = $23 + $24 = $47

Suppose you had a telephone directory listing all the businesses in a city, alphabetized by type of business. If you wanted to phone 100 of them to get a representative sampling of opinion on some issue, how would you select which 100 to phone? Why would it not be a good idea to simply use the first 100 businesses listed
Answer:
Step-by-step explanation:
The best way to select the 100 phone calls would be to randomly select the same amount of phone numbers from each individual type of business. This would make sure that there are no bias choices and would be 100% representative of the overall business market in every single type of business. If you choose the first 100 phone numbers you are choosing from only a handful of the same types of business and leaving out a lot of other types of business. This makes it impossible for the information gathered to be representative of the entire market.

a) Change 9 out of 50 to a percentage.
Hey there! Your question’s answer would be 18%..
Ok so 9/50 would be 9% out of 50% which is also 100%. If you want to find 50% turn to 100%, multiply 50 with 2 to get 100.
So you do the same thing to 9%. 9 times 2 would be 18%.
Final Result: 9% out of 100% (whole)
9 out of 50 in percentage equivalent terms will be 18% .
Given, 9 out of 50 to a percentage .
Convert fractions to percentage.
Multiply fraction by 100 , the result will be in percentage .
Fraction = [tex]\frac{9}{50}[/tex]
Percentage equivalent
[tex]\frac{9}{50} \times 100\\= 18[/tex]
Thus the percentage equivalent is 18% .

We can see that the graph is shaded to the left of -1. This means that x is all values less than (<) -1, so C and D are incorrect. Additionally, since the dot is not filled in, this means that x is not going to be equal to -1, which eliminates B. This leaves A, x < -1.

Solve for the variable: 6/25 = d/30
Answer:
d = 7.2
Step-by-step explanation:
We can cross multiply the equation to get:
6 * 30 = 25 * d
(* is multiplication sign by the way)
180 = 25d
Divide both sides by 25 to get:
d = 7.2
Jacob is building a rectangular prism for a class project. He needs
to cover the entire prism in aluminum foil. The length of the prism
is 8 centimeters, the width is 6.5 centimeters, and the height is 3
centimeters. How much aluminum foil will Jacob need for his
project?
Answer:
156 centimeters
Step-by-step explanation:
its very simple
8*6.5*3=156
Surface area of a rectangular prism is the sum area of the six sides.
A=2(xy+xz+yz)
A=2(8(6.5)+8(3)+6.5(3))
A=2(52+24+19.5)
A=2(95.5)
A=191 cm^2
