Mrs. Hart went to get her nails done at the salon. The cost was $35.00. What is the total amount if tax is 6% and she wants to leave a 18% tip?
A. $24.00
B. $43.40
C. $8.40
D. $59.00
Answer:
B) $43.40
Step-by-step explanation:
For the tax, 6% of 35 = 2.1
So with tax = $35 + 2.1 = $37.1
18% tip
So, 18% of 35 = 6.3
So we are gonna add all the costs together = 37.1 + 6.3 = $43.40
Answer:
Answer:
B) $43.40
Step-by-step explanation:
For the tax, 6% of 35 = 2.1
So with tax = $35 + 2.1 = $37.1
18% tip
So, 18% of 35 = 6.3
So we are gonna add all the costs together = 37.1 + 6.3 = $43.40

Answer:
The slope of the line passing through (1, 2) and (3, 8) is:
Slope = 3
Step-by-step explanation:
Given the points
(1, 2)(3, 8)Here:
(x₁, y₁) = (1, 2)
(x₂, y₂) = (3, 8)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [8 - 2] / [3 - 1]
= 6 / 2
= 3
Thus, the slope of the line passing through (1, 2) and (3, 8) is:
Slope = 3

A falling object travels a distance given by the formula d=3t+5t2, where d is measured in feet and t is measured in seconds. How many seconds will it take for the object to travel 84 feet?
Answer:
Approximately 3.81 seconds
Step-by-step explanation:
d = 3t + 5t²
d = 84
84 = 3t + 5t²
3t + 5t² - 84 = 0
5t² + 3t - 84 = 0
5(t² + 3/5t - 84/5) = 0
5(((t + 3/10)² - 9/100) - 84/5) = 0
5((t + 3/10)² - 9/100 - 84/5) = 0
5((t + 3/10)² - 9/100 - 1680/100) = 0
5((t + 3/10)² - 1689/100) = 0
5(t + 3/10)² - 1689/20 = 0
5(t + 3/10)² = 1689/20
(t + 3/10)² = 1689/100
t + 3/10 = ±√(1689)/10
t = -3/10 ± √(1689)/10
t = -3/10 ± ≈41.1/10
t = -3/10 ± ≈4.11
t ≈ -0.3 ± 4.11
t [can only be positive] ≈ 4.11 - 0.3
t ≈ 3.81

Given f(x)=14(5−x)2 what is the value of f(11)?
Answer:
I was unsure about the way your question was written so I solved for two equations: f(x)=14(5-x)*2 and f(x)=14(5-x)+2
Step-by-step explanation:
Given f(x) = 14(5−x)², the value of f(11) = 504
The given function is:
f(x) = 14(5 - x)²
To get the value of f(11), substitute x = 11 into the function f(x) = 14(5 - x)²
f(11) = 14(5 - 11)²
Simplify the expression
f(11) = 14(-6)²
f(11) = 14(36)
f(11) = 504
Therefore, given f(x) = 14(5−x)², the value of f(11) = 504

$7,425.00
$74.24

$12.38
The simple interest earned by Donna by the end of the sixth year is $74.24
What is simple interest?Simple interest is the interest charge on borrowing that's calculated using an original principal amount only and an interest rate that never changes.
Given that, Donna deposits $275 into her savings account for 6 years, the account earns 4.5% simple interest each year,
We need to find the interest earned by the end of the sixth year
Simple Interest = PRT / 100
Where,
P = Principal ($275)
R = rate (4.5%)
T = time (6 years)
SI = 275 × 6 × 4.5 / 100
= 7425 / 100
= 74.25
Hence, the simple interest earned by Donna by the end of the sixth year is $74.24

Answer:
There were 118,637 personal care aides in 2014.
Step-by-step explanation:
By 2024, there will be a need for 160,328 personal care aides, a growth of about 26% over 2014 levels.
This means that the 2014 levels is 100% - 26% = 74% of the 2024 levels.
Number of personal care aides in 2014:
74% of 160,320. So

There were 118,637 personal care aides in 2014.
Is x = 6 a solution to the equation x + 13 = 18?
Answer:
No, the answer is 5
Answer: No the solution is 5
Step-by-step explanation:
When you substitute x with 6 you get 6+13= 18.
Obviously 6+13 is not 18 so this means that 6 is not a solution.

What is the value of x?
Two possible floor plans for a new bathroom are shown.
Is there a value for x for which the perimeters are equal?
What is the linear equations?
Answer:
Hope it works for u
Step-by-step explanation:
As we have given two shapes bathroom
square and rectangle
Parameter of square= sum of all the sides ( : In square all sides are equal
Parameter of square= 4*L = 4*(x+3) (:L=x+3
similarly,
In rectangle opposites sides are equal hence
Perimeter of rectangle= 2*length+2*width ( : length=x+4,width can't be seen clearly so I assume and take it width=x+1 hope this is equal to the width of ur question otherwise do the calculation by ur self).
Perimeter of rectangle= 2*(x+4)+2(x+1)
so now we have to find the value of "x" for which both perimeter are equal, so
perimeter of square= perimeter of rectangle
4*(x+3)=2*(x+4)+2(x+1) we can also write as
2(x+3)+2(x+3)=2(x+4)+2(x+1)This is the linear equation requirednow to find value of "x"simplify both sides, we get4x+12=4x+100≠2 so that not true and also there is no value of "x"for which both parameters become equal
so from my side "b" option is correctPlease brain-list it if u find it help-full it requires effort!
Answer: B option is correct. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.

Find the length of BC, in simplest radical form.
9514 1404 393
Answer:
BC = 16 +12√3
Step-by-step explanation:
In the attached, we see that ∆ABE is a 30°-60°-90° triangle with AB the short side and BE the hypotenuse. Then BE = 2·AB = 12√3.
EC is the side opposite AD in parallelogram ADCE, so is the same length, 16.
The length BC is ...
BC = EC +BE

Write an expression to represent the perimeter of a rectangle with the length of x -4 and width of 2x +8.
Answer:
2(x-4) + 2(2x+8) OR long way (x-4) + (x-4) + (2x+8) + (2x+8)
Step-by-step explanation:
2(x-4) represents the (x-4) + (x-4) in the longer version since for perimeter you add the sides. Same thing for the other side, 2(2x+8) represents (2x+8) + (2x+8).
Not sure if you need the expression solved but here:
[tex]2(x-4) + 2(2x+8)\\(2x-8) + (4x+16)\\=6x+8[/tex]
To get from first line to second, use distributive property. To get from second to third line, combine like terms.
The perimeter of a rectangle with the length of (x - 4) and width of
(2x +8) will be (6x + 8).
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
We have to given that;
The length of rectangle = x - 4
The width of rectangle = 2x + 8
Now,
Since, The length of rectangle = x - 4
The width of rectangle = 2x + 8
We know that;
The perimeter of rectangle = 2 (Length + Width)
⇒ The perimeter of rectangle = 2 (x - 4 + 2x + 8)
⇒ The perimeter of rectangle = 2 (3x + 4)
⇒ The perimeter of rectangle = (6x + 8)

Which graph represents this system? 2x-5v=-5 y=-3x+1
Answer:
Please check the attached graph.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the system of equations
2x - 5y = -5 --- [Equation 1]
y = -3x + 1 --- [Equation 2]
converting the equation 1 in the slope-intercept form
2x - 5y = -5
5y = 2x+5
divide both sides by 5
y = 2/5x + 1
Thus, the y-intercept = 1
Now, please check the attached graph below.
The red line represents the equation 2x - 5y = -5
From the graph, it is clear that the red line has the y-intercept y = 1.
Now, considerng the equation 2
y = -3x + 1
comparing with the slope-intercept form of line equation
The y-intercept b = 1
Hence, the y-intercept of the line y = -3x + 1 is y = 1
The green line represents the equation y = -3x + 1
From the graph, it is clear that the green line has the y-intercept y = 1.
Point of Intersection:
It is clear from the graph:
The red line represents the equation 2x - 5y = -5.The green line represents the equation y = -3x + 1.As both lines meet or intersect at the point (0, 1).
Therefore, the point of intersection of both the lines is:
(x, y) = (0, 1)
As we know that the point of intersection of both the lines represents the solution to the system of equations.
Therefore, (0, 1) on the graph represents the solution to the system of equations.
The graph is attached below.
