A store has clearance items that have been marked down by 25%. They are having a sale, advertising an additional 45% off clearance items. What percent of the original price do you end up paying?
we end up paying 41.25 % of the original price after the addition sale on the clearance.
Let the original price of the good be x
Now, there is a sale of 25 %.
So the price will become
Price = x - 25 % of x
Price = x - 25 / 100 x
Price = x - 0.25 x
Price = 0.75 x
Now, there is an addition 45 % sale on the price.
so the price become:
New price = P = 0.75 x - 45 % of 0.75 x
P = 0.75 x - 45 / 100 (0.75 x)
P = 0.75 x - 0.45( 0.75 x)
P = 0.75 x - 0.3375 x
P = 0.4125 x
percentage of original price is:
P = 41.25 % of x
Therefore, we get that, we end up paying 41.25 % of the original price after the addition sale on the clearance.

Answer:
1:30 pm
Step-by-step explanation:
You want the time when Sahil catches up to Joaquin, who left at 8 am riding 50 mph when Sahil left at 8:30 am, riding at 55 mph.
Time, Speed, DistanceThe relation between time, speed, and distance is ...
distance = speed × time
time = distance / speed
Joaquin has a head start of 0.5 hours (30 minutes), during which time he traveled ...
head start distance = (50 mi/h) × (0.5 h) = 25 mi
Sahil is traveling 55 - 50 = 5 mph faster than Joaquin, so closes that gap at the rate of 5 mi/h. The time it takes to close the gap entirely is ...
time = distance / speed = 25 mi / (5 mi/h) = 5 h
So, 5 hours after Sahil starts at 8:30, the two riders will be at the same place.
Sahil catches Joaquin at 1:30 pm.
__
Additional comment
By the time the gap is closed at 1:30 pm, both riders will have traveled a distance of ...
distance = speed × time = 50 mi/h × 5.5 h = 55 mi/h × 5 h = 275 mi
In the attached graph, we have written equations for the total distance traveled by each motorcycle. The x-value used is the clock time on a 24-hour clock. That is, their meeting time of 13.5 hours corresponds to 13:30 hours or 1:30 p.m. on a 12-hour clock.
Karen worked her 40 regular hours last week, plus 6 hours at the time-and-a-half rate. Her gross pay was $650. What was her hourly rate?
As Karen worked for 40 regular hours and 6hours overtime at the rate of 1.5 regular hours and her gross pay was $650 then her hourly rate is $13.27 (approximately).
As given,
Regular working hours =40 hours
Overtime at the rate of (1.5 of regular hours) = 6 hours
Gross pay =$650
Let 'h' be the hourly rate
Required equation
40h + 6(1.5h) =650
⇒ 40h +9h=650
⇒49h=650
⇒h=$13.27(approximately)
Therefore, as Karen worked for 40 regular hours and 6hours overtime at the rate of 1.5 regular hours and her gross pay was $650 then her hourly rate is $13.27 (approximately).

What of the following is not a vertical asymptote of the function

Rewrite the function as
[tex]f(x) = \dfrac{\tan(\left(\frac{\pi x}4\right)}{x^2 - 8x + 15} = \dfrac{\sin\left(\frac{\pi x}4\right)}{\cos\left(\frac{\pi x}4\right) (x-3) (x-5)}[/tex]
Vertical asymptotes occur wherever the denominator is zero (but not necessarily when the numerator is also zero).
We have
[tex]\cos\left(\dfrac{\pi x}4\right) (x-3) (x-5) = 0[/tex]
[tex]\implies \cos\left(\dfrac{\pi x}4\right) = 0 \text{ or } x - 3 = 0 \text{ or } x - 5 = 0[/tex]
In the first case, we have
[tex]\cos\left(\dfrac{\pi x}4\right) = 0 \implies \dfrac{\pi x}4 = \pm\dfrac\pi2 + 2n\pi \implies x = \pm 2 + 8n[/tex]
where [tex]n[/tex] is an integer. That is, any of [tex]x\in\{\ldots,-10,-2,\boxed{6},14,\ldots\}[/tex] and [tex]x\in\{\ldots,-6,\boxed{2},10,18,\ldots\}[/tex] are asymptotes.
In the latter two cases, we get [tex]x=\boxed{3}[/tex] or [tex]x=\boxed{5}[/tex]. The numerator is finite at these values [tex]\left(\sin\left(\frac{3\pi}4\right)=\frac1{\sqrt2}\text{ and } \sin\left(\frac{5\pi}4\right)=-\frac1{\sqrt2}\right)[/tex].

Jet A Travels at 417 mph and gets halfway to its destination in two hours. Jet B makes the same journey but makes it to the destination in 5 minutes. How fast is Jet B in MPH, or how much faster is Jet B than Jet A As A Multiplier?
Example: 417 * 48 = 20016 Or Jet B = X MPH
I think the answer is 417 * 48 = 20016 and Jet B= 20016
But I just need reassurance, or a definitive answer
Answer:
Jet B speed: 20,016 mphspeed multiplier: 48Step-by-step explanation:
You want the speed and speed multiplier for Jet B given that it makes a journey in 5 minutes that takes Jet A 2 hours for half the journey.
Speed multiplierFor the same distance, speed is inversely proportional to time.
speed multiplier = (speed B)/(speed A) = (time A)/(time B)
speed multiplier = ((2 h)/(1/2))/(5 min)
speed multiplier = (240 min)/(5 min) = 48
SpeedThe speed of Jet B is 48 times that of Jet A:
48(417 mph) = 20016 mph . . . . speed of Jet B
__
Additional comment
The time for the full trip by Jet A can be found using the proportion ...
partial time/partial distance = total time/total distance
If the total distance is "1 unit", then this proportion is ...
(2 h)/(1/2) = t/1 . . . . . where t/1 = t is the time for the full trip by Jet A
You will recognize the value (2 h)/(1/2) as the time value we used for Jet A in the above solution.
Find the probability that there are no T when a fair coin is flipped three times.
The probability that no Tails is achieved on flipping a fair coin for three consecutive times is [tex](\frac{1}{8})[/tex].
As per the question statement, we are to flip or toss a fair coin thrice consecutively.
We are required to calculate the probability that no Tails is achieved during the above mentioned event.
To solve this question, first let us calculate all the possible outcomes of flipping a fair coin thrice consecutively. [We will denote a Heads outcome as "H" and a Tails outcome as "T"]
The total number of outcomes can be given by the formula [tex](2^{n})[/tex], where "n" is the number of times, the coin is tossed.
Here, (n = 3), therefore, total number of outcomes in our case [tex]=(2^{3})=8[/tex].
These 8 outcomes can be listed as [tex][{(H, H, H), (H, H, T), (H, T, H), (H, T, T), (T, H, H), (T, H, T), (T, T, H), (T, T, T)}][/tex]
And among the above listed 8, our favorable outcome is (H, H, H), i.e., 1 favorable outcome of 8.
Hence, probability that no Tails is achieved on flipping a fair coin thrice consecutively = [tex]\frac{1}{8}[/tex].
Probability: In Mathematics, probability is the chance to of the occurrence of a specific event among the occurrence of all possible events, and is measured by the ratio of the favorable cases to the whole number of cases possible.To learn more about Probability, click on the link below.

The total cost of a jacket and a pair of pants was $52.37. If the price of the jacket was $4.87 less than the pair of pants, what was the price of the jacket? Express your answer as a simplified fraction or a decimal rounded to two places.
The price of the jacket is $23.75
Let m be the price of a jacket and n be the price of pair of pants.
The total cost of a jacket and a pair of pants was $52.37
So, we get an equation,
m + n = 52.37 ................(1)
Also, the price of the jacket was $4.87 less than the pair of pants
So, we get an equation,
m = n - 4.87 .............(2)
Substitute above value of m in equation (1)
⇒ (n - 4.87) + n = 52.37
⇒ 2n - 4.87 = 52.37
⇒ 2n = 52.37 + 4.87
⇒ 2n = 57.24
⇒ n = 28.62
This means, the cost of a pair of pants is $28.62
Substitute above value of n in equation (2)
⇒ m = n - 4.87
⇒ m = 28.62 - 4.87
⇒ m = 23.75
This means, the cost of a jacket is $23.75
Therefore, the price of the jacket is $23.75

P = perimeter of the rectangle
P = 2*(length + width)
P = 2*(5x+x)
P = 2*(6x)
P = 12x
Set this equal to the stated perimeter (108) and solve for x.
12x = 108
x = 108/12
x = 9 feet is the width
5x = 5*9 = 45 feet is the length
