The plasma television is selling for $425 after the 15% discount.
What is the Selling price and cost price?
The selling price of a product is the price at which it is sold to the customer. It is the price that the customer pays for the product, and it includes any taxes or additional charges.
The cost price, also known as the wholesale price or the wholesale cost, is the price at which the manufacturer or supplier sells the product to the retailer or the distributor. It is the price that the retailer or distributor pays to acquire the product, and it does not include any taxes or additional charges.
If an item is marked 15% off, that means that you will pay 85% of the original price. To calculate the selling price of the plasma television, you can use the following formula:
Selling price = Original price x (100 - discount%) / 100
In this case, the original price of the television is $500 and the discount is 15%, so the selling price is:
Selling price = $500 x (100 - 15) / 100 = $500 x 0.85 = $425
Hence, the plasma television is selling for $425 after the 15% discount.

What is tempreture?Temperature in mathematics is usually referred to as a measure of the average kinetic energy of the particles in a system. The higher the temperature of the system, the more energetic the particles are and the more likely they are to move around. Temperature is usually measured in Kelvin, Celsius, Fahrenheit, or Rankine.
The new temperature in Moscow is now +2 °C.
The temperature falls by 6 degrees Celsius from 4°C to -2°C. This drop in temperature is an example of how quickly the weather can change in Juneau. The city is located in Southeast Alaska, along the coast of the Gulf of Alaska. This means that it is often subject to sudden shifts in temperature and weather patterns due to its close proximity to the ocean. The high humidity and large temperature range make Juneau a great place for outdoor activities like kayaking, fishing and hiking.

Tom took 1/2hours to clean the den. Then he took 2 1/8 hours to clean the bedroom. How much total time did Tom take to clean the two rooms?
Answer:
Step-by-step explanation:
First convert the mixed number into a fraction:2 1/8 = 17/8
And convert 1/2 to 4/8 for greatest common denominatorThen do fraction addition:4/8 + 17/8 = 21/8
Convert improper fraction to mixed number:21/8 = 2 5/8
Therefore, Tom took 2 and 5/8 hours to clean the two rooms
Answer: 2 5/8 hours ( 2 hours and 38 mins [rounded])
Step-by-step explanation: For the best experience, look at the attachment:
So, first I took the numbers and set up an addition problem. But we have a problem. They both don't have the same denominator. So first, we need to find a common denominator before we add. So, luckily we know that 2 is a factor of 8. So 1/8 would stay the same and we'd multiply the 2 by 4 to get the denominator, and 1 by 4 to get the denominator. Then, you'd add 2 1/8 to 4/8 to get 2 5/8. Also, I converted 5/8 of an hour to get 37.5 mins, so I rounded up to 2 hrs and 38 mins.

After a price was decreased by 15%, it became $2176. What would the price be if
the price was increased by 10% first, and then decreased by 25%?
This is due today, I REALLY NEED HELP!
Answer:
If the price was decreased by 15% and the price became $2176, the original price would be:
$2176 / (1 - 0.15) = $2176 / 0.85 = $2560
If we first increase the price by 10% and then decrease it by 25% we can use the following method:
Multiply the original price by 110% to increase it by 10%: $2560 * 1.1 = $2816
Multiply the increased price by 75% to decrease it by 25%: $2816 * 0.75 = $2,112
So the price would be $2,112 if the price was increased by 10% first, and then decreased by 25%.
It's Lila's turn to host movie night, and she's picking movies to rent. Flick City Digital Movies is having a sale, so Lila rents 5 movies for a total of $24.75. Each movie costs the same amount, Let c represent the cost to rent a movie. Which equation models the problem? c/5 = 24.75 5c = 24.75
Answer:
5c = 24.75
Step-by-step explanation:
5c = 24.75 If you divide both sides by 5, you will find out how much each movie cost.
[tex]\frac{5c}{5}[/tex] = [tex]\frac{24.75}{5}[/tex]

The probability that the Islanders will win exactly zero is 0.300763
How to determine the probability that the Islanders will win exactly zeroFrom the question, we have the following parameters that can be used in our computation:
Number of games = 3
Probability of winning = 33%
This means that
Probability of losing = 1 - Probability of winning
Substitute the known values in the above equation, so, we have the following representation
Probability of losing = 1 - 33%
Evaluate
Probability of losing = 67%
The probability that the Islanders will win exactly zero is calculated as
P = Probability of losing^3

Arithmetic progression can be defined as the sequence of numbers which has same difference between any consecutive numbers.
Given,
A ball is dropped from the height 160cm
And the ball loses 25% of its previous height after each bounce.
so,
for every bounce the height will be decreased by 25%
after first bounce , 160 - 160/4 = 120
after second bounce , 120 - 120/4 = 90
after third bounce , 90 - 90/4 = 67.5
The sequence could be 160,120,90,67.5 and soon
if a1 / a2 = a2/a3
it is said to be in gp
so a1/a2 = 120/160 = 0.75
a2/a3 = 90 / 120 = 0.75

The probability of rolling a 3 on a fair 6-sided die that P(3) is 0.17.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Since each side of the die is equally likely to land face up,
So the number of favorable outcomes n(E) = 1
And the total number of outcomes n(S) = 6
Thus, P(3) is the probability of rolling a 3 on a fair 6-sided die :
P(3) = n(E)/n(S)
