The probability of flipping heads on a coin and then flipping the coin again and getting heads is 0.25 or 25%.
Explanation:To find the probability of flipping heads on a coin and then flipping the coin again and getting heads, we need to multiply the probabilities of each event. The probability of flipping heads on a fair coin is 0.5. Since each flip of the coin is independent, we can multiply the probabilities together: 0.5 * 0.5 = 0.25. Therefore, the probability of flipping heads on a coin and then flipping the coin again and getting heads is 0.25 or 25%.

$1725 couch with a 15% markup
To find the final price of the couch with a 15% markup, we add the markup to the original price of the couch.
Explanation:In this question, we are given a couch priced at $1725 with a 15% markup. To find the final price, we need to add the markup to the original price of the couch.
Markup = 15% of $1725 = (15/100) * $1725 = $258.75
Final price = Original price + Markup = $1725 + $258.75 = $1983.75

K=59(F−32)+273.15. Solve for F.
Answer:
The value of the equation for F is [tex]F=\frac{K-273.15}{59}+32[/tex]
Step-by-step explanation:
Consider the provided equation.
[tex]K=59(F-32)+273.15[/tex]
We need to solve the provided equation for F.
Subtract 273.15 from both sides.
[tex]K-273.15=59(F-32)[/tex]
Divide both side by 59.
[tex]\frac{K-273.15}{59}=F-32[/tex]
[tex]F-32=\frac{K-273.15}{59}[/tex]
Add 32 from both side.
[tex]F=\frac{K-273.15}{59}+32[/tex]
Hence, the value of the equation for F is [tex]F=\frac{K-273.15}{59}+32[/tex]

Marcia states that 'some numbers have an odd number of factors'.
Let us consider the number 36. Now, it is given that,
1 × 36 = 36
2 × 18 = 36
3 × 12 = 36
4 × 9 = 36
6 × 6 = 36
Since, the repeated factor is counted only once. So, the factors of 36 are given by 1, 2, 3, 4, 6, 9, 12, 18 and 36.
This gives us that 36 has 9 factors and so, it has odd number of factors.
Hence, Marcia is correct.

The flow rate of a water pump is 2.8 gallons per minute. How many minutes does it take this pump to transfer 84 gallons of water out of a swimming pool? PLZ help me
It will take 30 minutes for the pump to transfer 84 gallons of water out of the swimming pool using the flow rate of 2.8 gallons per minute.
To calculate the time it takes for the water pump to transfer 84 gallons of water at a rate of 2.8 gallons per minute, you can use the formula for time, which is time = total volume/flow rate.
Firstly, find the total volume of water to be transferred, which is 84 gallons.
Next, find the flow rate of the pump, which is 2.8 gallons per minute.
Divide the total volume by the flow rate to find the time: 84 gallons / 2.8 gallons per minute = 30 minutes.
Therefore, it will take the pump 30 minutes to transfer all 84 gallons of water out of the swimming pool.

A recipe uses 8 3/4 cups of milk for every 3 1/2 cups of oatmeal.
How many cups of milk are used for each cup of oatmeal?
To figure out how many cups of milk are used for each cup of oatmeal, divide the amount of milk by the amount of oatmeal. The result is 2 1/2 cups of milk for each cup of oatmeal.
Explanation:The question is asking us to figure out what the ratio of cups of milk to cups of oatmeal would be if it were reduced to one cup of oatmeal. The original proportions provided in the question are 8 3/4 cups of milk for 3 1/2 cups of oatmeal.
To find the answer, we would divide the amount of milk by the amount of oatmeal. First, we need to convert the mixed numbers to improper fractions. 8 3/4 is the same as 35/4 and 3 1/2 is the same as 7/2.
Then, we divide 35/4 by 7/2, which turns into a multiplication problem: 35/4 times 2/7. Keep in mind that multiplying fractions is straightforward - you simply multiply the numerators with numerators and denominators with denominators.
The result, therefore, becomes 70/28 which simplifies to 2.5 or 2 1/2 when turned back into a mixed number. So, there are 2 1/2 cups of milk used for each cup of oatmeal.

The local movie theater collected a total of 8250 last night, of which 45% came from sales at the concession stand. How much money did the theater collect at the concession stand
To determine the concession stand revenue, multiply the total collected revenue, $8250, by 45%, resulting in $3712.50 collected at the concession stand.
To calculate how much money the theater collected at the concession stand, we first need to find 45% of the total revenue of $8250.
Step 1: Convert the percentage to a decimal:
45% = 0.45
Step 2: Multiply the total revenue by the decimal:
$8250 * 0.45
Step 3: Perform the multiplication:
$8250 * 0.45 = $3712.5
Therefore, the theater collected $3712.50 at the concession stand last night.

josh's web site had 805,289 visitors. Diego's site had 784,976 visitors. How many more visitors did josh's sit have than Diego's. Estimate to check your answer.
Josh's site had 20,313 more visitors than Diego's site. To estimate, we round the number of visitors to each site to the nearest thousand and subtract, revealing an approximate difference of 20,000 visitors, which is close to the exact count.
To find out how many more visitors Josh's site had than Diego's, we subtract the number of visitors to Diego's site from the number of visitors to Josh's site.
Josh's site had 805,289 visitors and Diego's site had 784,976 visitors. So we calculate:
805,289 - 784,976 = 20,313
Josh's site had 20,313 more visitors than Diego's site.
Estimate:
To estimate, we can round the numbers to the nearest thousand:
Josh's site: Approximately 805,000 visitors
Diego's site: Approximately 785,000 visitors
Now we subtract:
805,000 - 785,000 = 20,000
The estimate shows that Josh's site had about 20,000 more visitors than Diego's, which is close to the exact difference of 20,313 visitors.

David drove 135 miles in 3 hours Find the unit rate
To calculate David's unit rate of speed, divide the distance he traveled, 135 miles, by the time it took, 3 hours, which results in an average speed of 45 miles per hour.
The question concerns finding the unit rate of David's driving speed, which is a concept in mathematics related to distance and time. To find the unit rate of speed, we divide the total distance traveled by the total time taken. In this example, David drove 135 miles in 3 hours. Therefore, the unit rate (average speed) can be calculated as follows:
Identify the total distance traveled, d = 135 miles.Identify the total time taken, t = 3 hours.Calculate the unit rate (average speed) v using the formula v = d / t.The calculation would be v = 135 miles / 3 hours = 45 miles per hour.This means that David's average driving speed was 45 miles per hour.
