1. Miss Firkin is selling her Nike Air Force Ones. She bought them online for $75.00, but they were too big for her and she's tripping all over herself (scuffing the tips). She needs to make some extra money to buy Halloween candy....She wants to mark up the sneakers 150%. What is she charging for them?
2. Miss Firkin went to Wal-Mart and iced cupcakes that were $12.99 a box had a sticker that said 30% off. How much is one box?
What did she pay for 3 boxes?
3. Now, what if the cupcakes are taxed as fast food items at a rate of 9%?
4. How much does she now spend on the 3 boxes?
5. Gas was $1.25 per gallon. Now it is $1.38 per gallon. What percent did it increase by? (really not that tricky)
1. I beleive it would be 187,5$, 75.00 + 150% = 187,5.
2. if rounding it would be 9.1$ she had to pay for one times 3 would be 27.3 for three boxes.
3. Not sure what this question is asking but I'll try my best so here: 27.3 +9% × 3 = 89.271 rounded would be 90$
4. 90$ if I did that correctly
5. 1.38 - 1.25 = 0.13 which I beleive would be 13%
0.13 as a percent woudl be 13%
Stephanie and Bryson both grow tomatoes to sell at farmers' markets. Stephanie grew a total of 70 pounds
of tomatoes to sell. She plans to sell the tomatoes for $3.50 per pound. The equation below represents the
profit in dollars, f(x), she will earn by selling x pounds of the tomatoes.
f(x) = 3.50x -110
Bryson plans to sell his tomatoes at a different farmers' market. He grew a total of 90 pounds of tomatoes.
The table below shows the profit, in dollars, he will earn by selling different numbers of pounds of
tomatoes.

Profit (dollars)

Tomatoes Sold

Answer:
See below
Step-by-step explanation:
Stephanie's profit relationship:
f(x) = 3.50x - 110Bryson's Tomato Sales, using the pairs of numbers let's find the relationship.
(10, -97.50) and (20, -55.00)Since it is also linear relationship, we'll find a slope and y-intercept:
m = (-55 - (-97.50))/(20 - 10) = 42.50/10 = 4.25y-intercept is:
-97.50 = 4.25*10 + b ⇒ b = -97.50 - 42.50 = - 140So the function is:
g(x) = 4.25x - 140Comparing the functions:
f(x) = 3.50 - 110g(x) = 4.25 - 140The slope of g(x) is greater than f(x) but the y-intercept is smaller
It translates as:
Bryson sells tomatoes at greater price: 4.25 vs 3.50 per poundStephanie needs to sell 110/3.5 = 31.4 pounds of tomatoes before making any profitBryson needs to sell 140/4.25 = 32.9 pounds of tomatoes before making any profitHugo has 7 yards of wood.

Sam traveled 7.5 kilometers from his house to reach the highway. On the highway, he travels at an average speed of 55 kilometers per hour. Which equation can be solved to find t, the time in hours Sam travels on the highway to reach a farm 22 kilometers away from his house?
Answer:
0.2636 hrs
Step-by-step explanation:
Number of kilometers from Sam's house to highway = 7.5 km
Average speed traveled on highway = 55km/hr
Which equation can be solved to find t, the time in hours Sam travels on the highway to reach a farm 22 kilometers away from his house?
Time traveled (t) to reach a farm 22 kilometers from his house :
t = time in hours Sam travels on the high way:
Distance from highway to farm = (Distance of farm from Sam's house - distance from Sam's house to highway)
22km - 7.5km = 14.5km
Speed of travel on highway = 55kmph
Travel time = distance / speed
Travel time = 14.5km / 55km/hr
Travel time = 0.2636 hrs

(2x - 3)(x + 4) = 2x2 +____ - 12
Answer:
2x^2 + 5x - 12
Step-by-step explanation:
To distribute these two factors, use FOIL(First, Outer, Inner, Last) in this order.
(2x - 3)(x + 4) = 2x(x+4) - 3(x+4) = 2x^2 + 8x - 3x - 12 = 2x^2 + 5x - 12 .
(2x - 3)(x + 4) =
(2x * x) + (2x * 4) + (-3 * x) + (-3 * 4)

How many times smaller is a group of 19 coins than a group of 76 coins?
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
Ok I like looking at these type of questions like this. If you have 76 students and you want to put them in groups of 19. How many groups would you have?
That's easier for my brain to comprehend and now I know that all I have to do is divide the 76 students by 19 to get 4 groups.
So in your problem the 19 coins would be 4x smaller than the 76 coins.

Explanation:
It is hard to tell what sort of axioms or theorems you might have available to invoke for this proof. Here, we'll assume that you can use the fact that the sine function of acute angles maintains ordering:
sin(a) > sin(b) iff a > b . . . . . where 0 ≤ a, b ≤ 90°
__
Draw altitude TX, where X lies on RS. The sine relation tells you ...
TX/TS = sin(∠S)
TX/TR = sin(∠R)
Dividing the second equation by the first, we have ...
sin(∠R)/sin(∠S) = (TX/TR)/(TX/TS) = TS/TR
Given that ∠R > ∠S, we know sin(∠R) > sin(∠S), so we have ...
sin(∠R)/sin(∠S) = TS/TR > 1
TS > TR . . . . multiplying by TR

At Yvonne's auto dealing, car washes cost $5 for any time up to 10 minutes, plus $ .40 per minute after that. The managers at Yvonne's are trying to agree on a formula for calculating the cost c for a t-minute car wash. Sid thinks c = 0.4t + 5 is correct. Is he correct?
Answer:
He is incorrect
Step-by-step explanation:
Here, given the charge at the auto dealing, we want to know if the formula the managers came up with is correct
The base fee is $5 for 10 minutes or less
Now for any extra minute after the tenth, $0.5 will be paid
So for a t-minute wash, the amount to be paid will be;
C = $5 + 0.4( t- 10) = 5 + 0.4t - 4 = 1 + 0.4t
If t < 10 , C = $5
If t > 10, C = 1 + 0.4t
Sid is incorrect

the perimeter of an equilateral triangle is 8 inches more than the perimeter of a square, and the side of the triangle is 5 inches longer than the side of the square. Find the side of the triangle
Answer:
An equilateral triangle has all 3 sides the same length
If one side of the triangle has length x, the perimeter = 3x
If one side of the square is 5 less than a side of the triangle
then the square has side length x-5 and perimeter 4(x-5) = 4x-20
Since the perimeter of the triangle is 7 more than
the perimeter of the square then our equation is:
3x = 4x-20+7
3x = 4x-13
x = 13
The sides of the triangle are 13 inches
The sides of the square are 13-5=8 inches

The polynomial has 3 real zeros and 2 complex zeros.
What is polynomial function ?A quadratic, cubic, quartic, and other functions involving only non-negative integer powers of x are examples of polynomial functions. We can define a polynomial's degree and provide a generic definition for it.Zero polynomial function, linear polynomial function, quadratic polynomial function, and cubic polynomial function are the four most prevalent types of polynomials used in precalculus and algebra.A polynomial function whose all coefficients of the variables and constant terms are zero. In other words, zero polynomial function maps every real number to zero, f: R → {0} defined by f(x) = 0 ∀ x ∈ R.Both terms , the values of a polynomial f(x) that make f(x)= 0.
a polynomial whose coefficients are real numbers, but the field of real numbers is not algebraically closed.
The polynomial may very well have roots that are complex numbers, not real .
Let [tex]x^{2}[/tex] + 1 = 0 has root i and -i .
In this polynomial function we got 3 real zeros and 2 complex zeros.
