Answer:
C = 12 + 15(x - 4)
C = 15x - 48
Step-by-step explanation:
Let the number of hours = t
The total amount Miguel earns =
C
To edit a manuscript, Miguel charges 12 dollars per hour for the first 4 hours and 15 dollars per hour after the first 4 hours.
C = 12 + 15(x - 4)
Expand the t
C = 12 + 15x - 60
C = 15x - 48
Therefore, an expression for the amount, in dollars, Miguel charges if it takes him t hours to edit a manuscript, where t>4 is given as:
C = 15x - 48
need help with this question!!!
Answer:
36° and 54°
Step-by-step explanation:
Let one of the acute angle be "x"
We are told that the other acute angle is 1.5 times the other angle = 1.5x
The right angle = 90°
Find the value of x:
Therefore:
90 + 1.5x + x = 180 (sum of interior angles of triangle)
Add like terms
90 + 2.5x = 180
2.5x = 180 - 90
2.5x = 90
x = 90/2.5
x = 36° (one acute angle)
✔️Second acute angle = 1.5x
Plug in the value of x
= 1.5(36)
= 54°

Fill in the missing number in this newspaper report:
Houses cost £150000 one year ago
They now cost £
This is a 25% increase
Answer:
£187,500
Step-by-step explanation:
Cost of houses one year ago = £150000
Percent increase a year after = 25%
Increment = 25% * 150000
Increment = 0.25 * 150000
Increment = £37500
New cost of house after increment = £150000+ £37500
New cost of house after increment = £187,500

On comparing the ratios of the coefficients, find out whether the pair of equations x – 2y =0 and 3x + 4y -20 =0 is consistent or inconsistent.
Answer:
The pair of equations is consistent
Step-by-step explanation:
A consistent system of equations has at least one solution
The consistent independent system has exactly 1 solutionThe consistent dependent system has infinitely many solutionsAn inconsistent system has no solution
In the system of equations ax + by = c and dx + ey = f, if
a = d, b = e, and c = f, then the system is consistent dependent and has infinitely many solutionsa = d, b = e, and c ≠ f, then the system is inconsistent and has no solutiona ≠ d, and/or b ≠ e, and/or c ≠ f, and [tex]\frac{a}{d}[/tex] ≠ [tex]\frac{b}{e}[/tex] , then the system is consistent independent and has exactly one solution∵ x - 2y = 0
∴ The coefficient of x ⇒ a = 1
∴ The coefficient of y ⇒ b = -2
∴ The numerical term ⇒ c = 0
∵ 3x + 4y - 20 = 0
→ Add 20 to both sides
∴ 3x + 4y - 20 + 20 = 0 + 20
∴ 3x + 4y = 20
∵ The coefficient of x ⇒ d = 3
∵ The coefficient of y ⇒ e = 4
∵ The numerical term ⇒ f = 20
∵ a ≠ d
∵ b ≠ e
∵ c ≠ f
∵ [tex]\frac{a}{d}[/tex] = [tex]\frac{1}{3}[/tex]
∵ [tex]\frac{b}{e}[/tex] = [tex]\frac{-2}{4}[/tex] = [tex]\frac{-1}{2}[/tex]
∴ [tex]\frac{a}{d}[/tex] ≠ [tex]\frac{b}{e}[/tex]
→ By using rule 3 above
∴ The pair of equations is consistent

You bought 50 shares of stock at $55 per share and sold them for $61 per share. The sale involves a broker’s commission of $0.30 per share. What is your profit?
a) $215
b) $285
c) $315
d) $385
Answer:
The profit made is;
b) $285)
Step-by-step explanation:
The given parameters are;
The number of shares bought, n = 50
The price each share is bought, CP = $55
The amount at which each share is sold, SP = $61
The amount the broker received per share, E = $0.30
Therefore, the amount of profit, 'P', is given as follows;
P = n × (SP - CP - E)
By substituting the values for the variables, we have;
P = 50 × (61 - 55 - 0.3) = 285
The amount made as profit, P = $285.00.

Zellie is taking the stairs in her building from her floor to the top of the building. After 2 minutes, she was 100 steps from the bottom floor. After 5 minutes she was 196 steps from the bottom floor.
Answer:
The question seems to be incomplete, so i will think that this is a linear equation, where we can find the velocity at which she moves, and also her initial position.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
In this case we have two points:
"After 2 minutes, she was 100 steps from the bottom floor."
this can be represented with the point: (2min, 100 steps)
" After 5 minutes she was 196 steps from the bottom floor"
This can be represented with the point (5min, 196 steps)
With this, we can find the slope of this equation:
a = (196 steps - 100 steps)/(5min - 2min) = 96steps/3min = 32 steps/min
This means that she does 32 steps in one minute.
Then we can write her positon equation as:
y = (32steps/min)*x + b
where x represents the time, and b is her initial position.
If we replace x by 2 min, and y for 100 steps, we get:
100steps = (32steps/min)*2min + b
100 steps = 64 steps + b
100 steps - 64 steps = b = 36 steps.
This means that she started to take the stairs 36 steps from the bottom floor.
A jewelry artist is selling necklaces at an art fair. It costs $135 to rent a booth at the fair. The cost of materials for each necklace is $4.50. The artist is selling the necklaces at $12 each. The inequality 12n>135+4.50n represents the situation in which the artist makes a profit. a) Will the artist make a profit if she sells 15 necklaces?
Answer: No
Step-by-step explanation:
$12-$4.50= $7.50
$7.50*15= $112.50
The Total cost is $135 She will only be making $112.50 in profits.
You need to solve for x.

A.y=50+0.15x
B.y=50+0.45x
C.y=150+0.45x
D.y=150+0.15x
Answer:
D
Step-by-step explanation:
you get 150 by taking the product of 50 and 3, this eliminates answers 'a' and 'b'
since the question states the cost per mile driven is $1.50 and 'x' represents miles driven, D is the answer

Consider the parametric equations x = 4cos(t) – 3 and y = 5sin(t) + 2. What is the rectangular form?
Answer: C on edge
Step-by-step explanation:
The rectangular form of the parametric equations x = 4cos(t) – 3 and y = 5sin(t) + 2 is shown in the option third, option third is correct.
What are parametric equations?A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.
The missing options are in the attached picture please refer to the picture.
We have two parametric equations:
x = 4cos(t) – 3 and
y = 5sin(t) + 2
From the options plug x and y values in the equation:
[tex]\rm \dfrac{(x+3)^2}{16}+\dfrac{(y-2)^2}{25}=1\\[/tex]
[tex]\rm \dfrac{(4cos(t)-3+3)^2}{16}+\dfrac{(5sin(t)+2-2)^2}{25}=1\\[/tex]
[tex]\rm \dfrac{(4cos(t))^2}{16}+\dfrac{(5sin(t))^2}{25}=1\\[/tex]
cos²t + sin²t = 1 (true)
Thus, the rectangular form of the parametric equations x = 4cos(t) – 3 and y = 5sin(t) + 2 is shown in the option third, option third is correct.

During the first six months of the year, the car dealership sold 47 cars, 53 cars, 62 cars, 56 cars, 46 cars, and 48 cars. What was the average number of cars sold per month during the first six months of the year?
Answer:
52 cars
Step-by-step explanation:
During the first six months of the year the car dealership sold
53 cars
47 cars
62 cars
56 cars
46 cars
48 cars
Therefore the average number of cars sold per month can be calculated as follows
= 53+47+62+56+46+48/6
= 312/6
= 52
Hence an average of 52 cars is sold monthly
If Buddy the Elf stands 6'3" tall and looks up at the Empire State Building (1454' high), what is the angle of elevation if Buddy is 206' from the base of the Empire State Building?
Answer:
Step-by-step explanation:
If Buddy the Elf stands 6'3" tall and looks up at the Empire State Building (1454' high), what is the angle of elevation if Buddy is 206' from the base of the Empire State Building?
We are to find the angle of elevation which is calculated using the Trigonometric function of Tangent.
tan θ = Opposite/Adjacent
Where:
Opposite = 1454'
Adjacent = 206
tan θ = 1454'/206
The cost of a car rental is $25 per day plus 22 per mile. You are on a daily budget of $90. Write and solve an inequality to find the greatest distance you can drive each day while staying within your budget. Use pencil and paper. Find 2 other two-step inequalities with the same solutions.
Answer: You can drive, at most, 2.95 miles per day.
x ≤ 2.95
Step-by-step explanation:
In a single day, you can spend at most $90
Then if C represents the cost of renting the car, then we will have the inequality:
C ≤ $90
Now let's find the equation for C.
We know that we have a fixed cost of $25 plus $22 per mile, then if you drive x miles, the total cost will be $25 plus x times $22, or:
C = $25 + x*$22.
We can now replace that in the inequality:
$25 + x*$22 ≤ $90
Now let's isolate the variable x
x*$22 ≤ $90 - $25
x*$22 ≤ $65
x ≤ $65/$22 = 2.95
x ≤ 2.95
You can drive at most, 2.95 miles per day.
To find other inequalities with the same solution we can start with the solution:
x ≤ 2.95
Now let's multiply both sides by a number (the units of the number can be dollars, in that way we can make a similar problem)
Let's multiply both sides by $10:
x*$10 ≤ 2.95*$10 = $29.5
x*$10 ≤ $29.5
Now let's add the same number in both sides, for example, $5.
x*$10 + $5 ≤ $29.5 + $5 = $34.5
x*$10 + $5 ≤ $34.5
We could write this problem as:
"To rent a cab in your city, you have an initial cost of $5, plus $10 for each mile driven. How many miles could you drive if at most you can spend $34.50?"
You could be more creative with the problem, but this is the way in which you can craft problems of this type when you already know the solution.
What is the solution to 3|-3x+9|=-18?
Answer:
There is no solution to the problem.
Step-by-step explanation:
Key skills: Absolute Value, Division, One Variable Equation
1) We have the equation 3|-3x+9|=-18
2) First, divide by 3 on both sides.
-18/3 is -6
3) This means --> |-3x+9| = -6
4) Absolute Value cannot be negative so there is no solution.
Hope you understood and have a nice day!! :D
