Calculate the actual sales since the sales and sales tax were rung up together. Assume sales tax of 6% and total sales of $33,000.
Answer:
the actual sales be $31,132
Step-by-step explanation:
The computation of the actual sales is as follows:
Let us suppose the actual sales be x
Now the sales tax be 0.06x
Now the total sales would be
x + 0.06x = $33,000
1.06x = $33,000
x = $33,000 ÷ 1.06
= $31,132
hence, the actual sales be $31,132
The same is to be considered by applying the above equation
Answer:
actual sales be $31,132

Step-by-step explanation:
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
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.

The sum of two numbers is 9. Their difference is 21
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:
f(x) = 26
Step-by-step explanation:
Evaluate the Function
f (x) = −4x + 6 f (−3) + 8
Replace the variable x with −3 in the expression.
f (−3) = −4 ⋅ −3 + 6
Simplify (−4 ⋅ −3 + 6) + 8
Multiply −4 by −3.
12 + 6 + 8
Add 12 and 6.

i’ll give u brainliest What is the degree measure of x?
Answer:
134 is the ONLY correct answer
Step-by-step explanation:
This is because it is asking for X, not the interior angle that's missing. You do need that angle to find the correct answer.
All triangles are equal to 180 degrees.
180-88-46=46
And all supplementary angles are equal to 180 degrees.
Therefore, 180-46 (as that is the only known angle) makes it 134 degrees.
67, 88 are not correct as one of them isn't obtuse and the other isn't to scale, 111 isn't correct as the math backs up 134 which is also an obtuse angle

Kannanaski Rapids drops 70 ft vertically over a horizontal distance of 866 ft. What is
the slope of the rapids?
-0.001
-12.4
-70
-0.081
I need help ASAP :(
Answer:
0.081
Step-by-step explanation:
Given parameters:
Vertical drop = 70ft
Horizontal distance = 866ft
Unknown:
Slope of the rapids =?
Solution:
Slope is the rise or vertical height divide by the horizonal distance.
Slope = [tex]\frac{vertical drop}{horizontal distance}[/tex]
Insert the parameters and solve;
Slope = [tex]\frac{70}{866}[/tex] = 0.081
Based on the information given the slope of the rapids is 0.081.
Slope of the rapids:Using this formula
Slope of the rapids=Vertically rapid drop/Horizontal distance
Let plug in the formula
Slope of the rapids=70ft/866ft
Slope of the rapids=0.0808
Slope of the rapids=0.081 (Approximately)
Inconclusion the slope of the rapids is 0.081.

Step-by-step explanation:
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):
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]
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.
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.

An SRS of 2,500 individuals was taken from a large city to estimate the percentage of city residents with a graduate degree. 555 people in the sample had a graduate degree. 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%
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]
