what is the square root of 20
Answers
Answer:
It is 4.472135955, which simplifies to 4.47
Step-by-step explanation:
Step-by-step explanation: The square root of 20 is not a perfect square.
In other words, it's impossible to find a whole number
times itself that gives us a product of 20.
However, we can simplify it.
20 breaks down into 2 x 10 and 10 breaks down into 2 x 5.
Since the 2's pair up as factors of 20, a 2 comes out of the radical.
Since the 5 doesn't pair up, it stays inside.
So our answer is 2√5.
The sum of two numbers is 9. Their difference is 21
Answers
Answer:
(15, -6)
Step-by-step explanation:
x + y = 9
x - y = 21
x = 9 - y
plug in x into second equation
9 - y - y = 21
9 - 2y = 21
-2y = 12
y = -6
plug in y.
x - (-6) = 21
x + 6 = 21
x = 15
check
15 + (-6) = 9
15 - (-6) = 21

Answer:-3/9
Step-by-step explanation:
When you adding or subtracting fractions they need to have the same denominator... which in the question they do! :) after you get your denominator the same you add the second numerator from the first one, in this one it’s 3 + (-6). Oh no a negative! But don’t worry when you add a negative it’s just like subtracting a regular number, so you really are just doing 3-6 which is -3 then you just put that over the denominator you had before, and you get -3/9

How long will the family be able to spend in Millersville if they want to spend less than $60 and
they don't have any other expenses?
Follow the steps to answer this question.

wrote the inequality, and define any variables used.
2. Solve your inequality. Show your work. What does your solution mean?
Answers
Answer: 36+4h=60
36+4h-36=60-36
4h=24
4h÷4=24÷4
h=6
So, after the move they can spend 6 hours there. (6×4=24, 24+36=60, they will spend $60 if they spend 6 hours there, $56 if they spend 5 hours there and don't want to spend $60).

A random sample of 16 ATM transactions at the Last National Bank of Flat Rock revealed a mean transaction time of 2.8 minutes with a standard deviation of 1.2 minutes. The width (in minutes) of the 95 percent confidence interval for the true mean transaction time is plus/minus (to three decimal places):
Answers
Answer:
The width is [tex]W = 1.2786[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 16
The mean time is [tex]\= x = 2.8 \ minute[/tex]
The standard deviation is [tex]s = 1.2 \ minutes[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = n - 1[/tex]
=> [tex]df = 16 - 1[/tex]
=> [tex]df = 15[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the t distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of df = 15 is
[tex]t_{\frac{\alpha }{2} , 15 } = 2.131[/tex]
Generally the margin of error is mathematically represented as
[tex]E = t_{\frac{\alpha }{2}, 15 } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 2.131 * \frac{ 1.2 }{\sqrt{16} }[/tex]
=> [tex]E = 0.6393 [/tex]
Generally the width the confidence 95% confidence interval
[tex]W = 2 * E[/tex]
=> [tex]W = 2 * 0.6393[/tex]
=> [tex]W = 1.2786[/tex]

The percentage of individuals in the city with a graduate degree is estimated as 22.2%. The estimated standard error is closest to:_______a. 1%b. 10% c. 0.1%
Answers
Answer:
The option is b
Step-by-step explanation:
From the question we are told that
The sample size is n = 2500
The number with a graduate degree is k = 555
The sample proportion is [tex]\^ p = 0.222[/tex]
Generally the standard error is mathematically represented as
[tex]SE = \sqrt{\frac{\^ p (1- \^ p )}{n} }[/tex]
=> [tex]SE = \sqrt{\frac{0.222 (1- 0.22 )}{2500 } }[/tex]
=> [tex]SE = 0.010[/tex]
Converting to percentage
[tex]SE = 0.010 * 100[/tex]
=> [tex]SE =10\%[/tex]

If a rectangular patio has a length that is 5 feet longer than its width and a perimeter of 54 feet, solve for the length.
1)17 feet
2)21 feet
3)16 feet
4)11 feet
Answers
Answer: (3)
Step-by-step explanation:
In this problem, we don't know the length or width. All we do know is that the length is 5 feet longer than the width, and that the perimeter is 54 feet. Both lengths plus both widths equals the perimeter. To solve this problem, you must give the width, the value of x.
Step 1: Draw a rectangle where the width is x and the length is x + 5.
Step 2: Find the sum of the lengths and the sum of the widths
2 times the length plus 2 times the width equals the perimeter
2(x + 5) + 2(x) = 54
Step 3: Solve for the width
2(x + 5) + 2(x) = 54
2x + 10 + 2x = 54 (Distributive Property)
4x + 10 = 54 (Group Like Terms)
4x = 44 (Subtraction Property of Equality)
4x/4 = 44/4
x = 11 (Division Property of Equality)
x = width = 11
Step 4: Solve for the length
x + 5 = length
11 + 5 = 16
Length = 16. So (3) must be the answer.

If you were to write this in y=mx+b, we know that m is the slope and b is the y-intercept. The slope represents the change in y over change in x. And the y-intercept represents the point at which the line crosses the y-axis.
Using this information, you can see that the line crosse the y-axis at -6. And since the line is going down, we know that the slope is negative.
So, your answer should be D) y=-3x-6

Linear Modeling
It's given a situation where a student has two summer jobs and wants to collect $750 to pay for a down payment on a car. He gets paid $25 for each lawn mowed and $15 for each pool cleaned
Create a model in standard formLet
x = number of lawns mowed
y = number of pools cleaned
He wants to make $750, thus:
25x + 15 y = 750
Dividing by 5, we have the model that represents the linear relationship:
5x + 3y = 150
Identify the x-interceptThe x-intercept can be found by setting y=0:
5x + 3(0) = 150
5x = 150
Dividing by 5:
x = 150/5 = 30
x = 30
This represents the situation where the student gets his $750 by only mowing 30 lawns, no pools cleaned.
Identify the y-interceptThe y-intercept can be found by setting x =0:
5(0) + 3y = 150
3y = 150
y = 150/3 = 50
y = 50
This represents the situation where the student gets his $750 by only cleaning 50 pools, no lawns mowed.
Identify two combinations that are solutions to the equationStarting from the basic equation
5x + 3y = 150
We can give x some arbitrary value (less than 30) and find the value for y.
For example, for x=12
5*12 + 3y = 150
60 + 3y = 150
3y = 150 - 60 = 90
y = 90/3=30
This solution corresponds to the case where the student gets $750 by mowing 12 lawns and cleaning 30 pools.
For example, for x=21
5*21 + 3y = 150
105 + 3y = 150
3y = 150 - 105 = 45
y = 45/3=15
This solution corresponds to the case where the student gets $750 by mowing 21 lawns and cleaning 15 pools.
Nikko needs to get his air-conditioner fixed. The repairman will charge Nikko a flat fee
of $50 plus an additional $20 for each hour he needs to work on it.
Write an equation to represent Nikko's total cost to repair his air-conditioner. Use t for total
cost and h for hours.
Answers
Answer:
$70
Step-by-step explanation:
50+20=70
The required expression is given for the Nikko is t = 50 + 20h.
Given that,
The repairman will charge Nikko a flat fee of $50 plus an additional $20 for each hour he needs to work on it.
The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
here,
t is the total cost the repairman charged to Nikko,
h is the number of hours,
repair men charges for h hours = $20h
repair men charge a flat fee of $50.
Total charge, t = 50 + 20h
Thus, the required expression given for the Nikko is t = 50 + 20h.
