Marge orders the following items and would like to leave a 20 percent tip based on her bill. There is no tax on her meal. What is the total cost of her dinner including gratuity? Item Amount Soup $3.75 Shrimp scampi $15.00 Iced tea $2.60 Dessert $4.25.
Answers
Answer:
The total cost of her dinner including tip would be $30.72
Step-by-step explanation:
Marge orders the following items on her meal.
Soup = $3.75
Shrimp scampi = $15.00
Iced tea = $2.60
Dessert = $4.25
The total cost of her dinner including gratuity is
3.75 + 15.00 + 2.60 + 4.25 = $25.60
She would like to leave a 20% tip based on her bill
Therefore, 20% of $25.60
= 0.20 × 25.60 = $5.12
Now add this tip amount to the bill amount.
$25.60 + $5.12 = $30.72
The total cost of her dinner including tip would be $30.72

To find this solution, you have to write an inequality. We want the new plan to be less than the old plan of $175.
So our inequality would be:
94 + 4.5x < 175
Solving it gives:
4.5x < 81
x < 18
So the number of devices must be less than 18. Draw an open circle at 18 with a ray going to the left to show those numbers.

Company A can produce 100 CPUs in 3 days while Company B can produce 150 CPUs in 4 days. If the two companies join forces, how many days would it take them to produce 1000 CPUs?
Answers
Hope this helped!
Answer: They would need 15 days
Step-by-step explanation:
The data is:
Company A produce 100 CPUs in 3 days, so the rate per day is:
Ra = 100/3 CPUs per day: 33.33 CPUs per day.
Company B produce 150 CPUs in 4 days, then it produces:
Rb = 150/4 = 37.5 CPUs per day.
Then, if both companies work toggeter, they produce
Ra + Rb = 33.33 + 37.5 CPUs per day = 70.83 CPUs per day.
We want to know the number X of days needed to make 1000 CPUs, then we need to solve:
70.83*X = 1000
X = 1000/70.83 = 14.11 days, we could round it up to 15 days if we want to have a whole number.
Sonya has four straws of different lengths: 2cm,8cm,14cm,and 16cm. How many triangles can she make using the straws?
Answers
You can make a triangle with 6, 14 and 16 straws.
The answer is one triangle
Im assuming you are not allowed to stick together any of the straws
There is no way to make a triangle with numbers 2,8,14, nor 2,8,16, nor 2,14, and 16. Using 6, 14, and 16 straws, you can form a triangle.
I'm guessing you're not supposed to stick any one of the straws together. Kindly see the accompanying document for more information. As a result, B is represented by one triangle. All two sides add up to more than the third side. As a result, the difference between the two sides is less than the difference between the first and third sides.Therefore, the final answer is "one triangle".

A room's length is 3 feet less than twice its width. The area of the room is 135 square feet. What are the room's dimensions?
Answers
Hope this helps:
A= L x W
135 = (2w-3)(W)
135 = (2w squared - 3W)
135 = 2w^2-3w
2w^2-3w-135 = 0
-----
Use the quadratic formula to get:
w = [3 +- sqrt(9 - 4*2*-135)]/4
Positive solution:
w = [3 + sqrt(1089)/4
w = [3 + 33]/4
w = 9 ft
L = 2W-3 = 2*9-3 = 15 ft.
If the width is w, the length is l = 2w-3.
The total area is length x width = w*(2w-3)
Solve
w*(2w-3)=135 to find w.
2w^2-3w-135=0
w = (3 +/- sqrt ( 9 +8*135))/4
The positive solution is
w = ( 3 + 33) /4 = 9 and then l = 15.
The dimensions of room are: Length = 15 feet and Width = 9 feet.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

we have,
A room's length is 3 feet less than twice its width.
The area of the room is 135 square feet.
let the width be x then length = 2x - 3.
So, Area of Room
135 = l w
135 = x (2x- 3)
2x² - 3x - 135= 0
2x² + 15x - 18x - 135 = 0
x (2x+ 15) - 9 (2x- 15)= 0
(2x+ 15)(x- 9)=0
x= -15/2 or x= 9.
Thus, the dimensions of room are:

A sign standing 6 feet tall is situated 18 feet away from a flag pole. at a certain time of day the sign's shadow is 3 feet long and the flagpole's shadow is 24 feet long. how tall is the flagpole?
Answers
On picture we have:
A = height of flagpole = x ft
B = length of flagpole's shadow = 24 ft
C = height of sign = 6 ft
D = length of sign's shadow = 3 ft
When we draw a picture representing this problem we can also add another line marked in red. This way we can see that we have two right-angle triangles. We can see that both have same angle marked with α.
We can apply trigonometry rules to find height of flagpole.
From small triangle containing sign we can find tangens function:
[tex]tan \alpha = \frac{C}{D} [/tex]
Similarly we can do for large triangle containing flagpole:
[tex]tan \alpha = \frac{A}{B} [/tex]
We see that these two equations have same left sides. This means that their right sides must also be same:
[tex]\frac{C}{D} = \frac{A}{B}[/tex]
We can solve for A:
[tex]CB=AD \\ A= \frac{CB}{D} \\ A= \frac{6*24}{3} \\ A=48 ft[/tex]
Height of flagpole is 48 feet.

x = 5y/3 + 5
Solve for the value of y in terms of x:
x – 5 = 5y/3

Answer:

Step-by-step explanation:
Using the normal distribution, it is found that P(z < −2.1) = 0.0179.
Normal Probability DistributionThe z-score of a measure X in a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure X is from the mean, if it is positive above the mean, if it is negative below. After finding the z-score, the z-score table gives the p-value of this z-score, which is the percentile of the measure X.From the z-table, we have that Z = -2.1 has a p-value of 0.0179, hence P(z < −2.1) = 0.0179.

Explanation:
1) (f/g)(x) = f(x) / g(x)
2)
f(x) 5x + 3
-------- = ------------
g(x) 6x - 5
3) Since the division by 0 is not defined, the domain is restricted to 6x - 5 ≠ 0.
Therefore you must solve 6x - 5 = 0 to exclude the value of x for which the denominator becomes 0:
6 x - 5 = 0 => 6x = 5 => x = 5 / 6.
So, the domain is all x | x ≠ 5/6.
Answer:
(f/g)(x) = Quantity five x plus three divided by six x minus five.domain {x|x ≠ Five over six. }
Step-by-step explanation:
Given functions,
[tex]f(x)=5x+3[/tex]
[tex]g(x) =6x-5[/tex]
[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]
[tex]=\frac{5x+3}{6x-5}[/tex] ( By substitution )
Let [tex]h(x)=\frac{5x+3}{6x-5}[/tex]
Which is the rational function,
Since, a rational function is defined for all real number except those for which denominator = 0,
[tex]6x-5=0[/tex]
[tex]6x=5[/tex]
[tex]x=\frac{5}{6}[/tex]
Thus, h(x) is defined on all real numbers except 5/6,
Hence, domain of [tex]\frac{f}{g}(x)[/tex] is {x| x ≠ [tex]\frac{5}{6}[/tex] }

[tex]\frac{(x - xc)^{2} }{ a^{2} } + \frac{(y - yc)^{2} }{ b^{2} } = 1[/tex]
Indeed, you have:
[tex]\frac{(x-3)^{2} }{64} + \frac{(y+5)^{2} }{100} = 1[/tex]
Therefore you can easily find:
a) the coordinates of the center:
in your case xc = 3 and yc = -5
hence C(3 , -5)
b) lenght of the major and minor axis:
in your case a² < b²:
a² = 64 ⇒ a = 8 (ATTENTION! This is the semi-minor axis)
b² = 100 ⇒ b = 10 (again, this is the semi-major axis)
Therefore,
minor axis 2a = 16 and major axis 2b = 20
c) coordinates of the foci:
Since you have a² < b², foci have the generic coordinates F₁₂ (xc , yc+/-c)
where c = √(b² - a²)
Let's compute c = √(100 - 64) = √36 = 6
yf₁ = -5 - 6 = -11
yf₂ = -5 + 6 = -1
Therefore:
F₁ (3, -11) and F₂(3, +1)

laura budgets $54 each month for annual expenses. she nets $1820 semimonthly. what percent of her net monthly income does she budget for annual expenses?
1%
3%
6%
8%
Answers
If she is getting $1820 semimonthly. That means that she is getting $3640 per month. 1820 x 2 = 3640
Now, we just need to find the percent of that which goes for the annual expenses.
Divide 54 by 3640 and multiply by it 100 to get a percent of 1.4% which can be rounded to 1%.
Explanation:
Since the income known in the problem is for semi-monthly (meaning every half of the month), we should compute for the monthly income because we what know is the amount of money Laura allots on a monthly basis for her annual expenses.
Since semi-monthly income is received twice per month, the monthly income of Laura is two times her semi-monthly income (= $1820). That is,
monthly income
= 2 × semi-monthly income
= 2 × $1820
monthly income = $3,640
Because $54 is budgeted each month for annual expenses, the percentage of the monthly income that is allocated for annual expenses is computed as
percentage of the monthly income
= ((monthly income allocated for annual expenses) ÷ (monthly income)) × 100%
= ($54 ÷ $3,640) × 100%
≈ 0.0148351648 × 100%
percentage of the monthly income ≈ 1%

cos(pi/3-pi/5) = cos(pi/3)cos(pi/5) + sin(pi/3)sin(pi/5)
cos(pi/3)cos(pi/5) + sin(pi/3)sin(pi/5) = cos(pi/3-pi/5)
cos(pi/3)cos(pi/5) + sin(pi/3)sin(pi/5) = cos(5pi/15-3pi/15)

A bicycle store costs $1700 per month to operate. The store pays an average of $75 per month. The average selling price of each bicycle is $95. How many bicycles must the store sell each month to break even?
Answers
The formula in computing the break-even point is:
Break-even = fixed cost / contribution margin
The fixed cost is already given which is $1700 per month. To compute for the contribution margin, you have to deduct the average cost per month ($75) to the selling price of each bicycle ($95). The contribution margin is $20 ($95 - $75).
Substituting the amounts to the formula:
Break-even = $1,700/$20
= 85
Therefore, the store must sell 85 bicycles each month to break even.
