A coin weighs 3/4
ounces. Trey picked up 6 of these coins.
What is the total weight of the coins he picked up?
Write your answer in simplest form.
Answer:
4 2/4
Step-by-step explanation:
3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4
To find the total weight of the coins Trey picked up, multiply the weight of one coin by the number of coins. The total weight is 9/2 ounces or 4.5 ounces in decimal form.
Explanation:To find the total weight of the coins Trey picked up, we need to multiply the weight of one coin by the number of coins picked up. The weight of one coin is 3/4 ounces, and Trey picked up 6 of these coins. To multiply a fraction by a whole number, we multiply the numerator (top number) of the fraction by the whole number. So, the total weight of the coins Trey picked up is (3/4) * 6 = 18/4 ounces.
Next, we simplify the fraction to its simplest form. To do this, we find the greatest common divisor (GCD) of the numerator and denominator, and divide both by the GCD. In this case, the GCD of 18 and 4 is 2. Dividing both the numerator and denominator by 2, we get 18/4 = 9/2. So, the total weight of the coins Trey picked up is 9/2 ounces or 4.5 ounces in decimal form.

If 15 out of every 75 new salons are still open for business after 3 years, what percent of salons are NOT still in business after 3 years?
Answer:
80%
Step-by-step explanation:
If 15 salons are open, this means that 60 are closed. 60 out of the 75 salons is 80% if you divide 60 by 75.
Final answer:
To find the percentage of new salons not still in business after 3 years, subtract the number still open from the total, divide by the total number of salons, and multiply by 100. This calculation shows that 80% of the new salons have closed.
Explanation:
The question asks us to find what percent of new salons are not still in business after 3 years given that 15 out of every 75 are still open. First, we find the number of salons that closed. Since 15 salons are still open, the number that closed is 75 - 15, which equals 60 salons. To find the percentage of salons that closed, we divide the number of closed salons by the total number of new salons, and then multiply by 100.
So, the calculation to find the percentage that closed is:
(60 closed salons / 75 total salons) × 100 = 80%
Therefore, 80% of the new salons are not still in business after 3 years.

A French submarine is at a depth of -200 meters, and a Russian submarine is at
a depth of -205 meters, which submarine is deeper?
A. French submarine
B. Russian submarine
The Russian submarine is deeper since -205 meters is a greater depth than -200 meters when comparing negative values.
To compare the depths of the two submarines, we need to consider the numerical value of their depths. When we look at depths, the larger the negative number, the deeper the location. In this case, a depth of -200 meters means the French submarine is closer to the surface than a depth of -205 meters.
Therefore, the Russian submarine is deeper because -205 is lower than -200 when considering depths below sea level.

y = 6 - x
The missing y values are at x = 4, 8 and x = 12
Substitute the known values in the above equation, so, we have the following representation

There are 5 pennies, 7 nickels, and 9 dimes in an antique coin collection
two coins are to be selected at random from the collection. Find each
10. P(selecting 2 pennies), if no replacement occurs
11. P(selecting 2 pennies), if replacement occurs
12. P(selecting the same coin twice), if no replacement occurs
Answer:
10. 4.8%
11. 5.67%
12. 30.39%
Step-by-step explanation:
The total number of coins is 5 + 7 + 9 = 21 coins
The probability of selecting two pennies without replacemente is:
First penny: 5 possibilities over 21 coins: 5/21
Second penny: 4 possibility over 20 coins: 4/20
P(selecting 2 pennies) = (5/21) * (4/20) = 1/21 = 0.048 = 4.8%
With replacement, we have:
First penny: 5 possibilities over 21 coins: 5/21
Second penny: 5 possibilities over 21 coins: 5/21
P(selecting 2 pennies) = (2/21) * (2/21) = 25/441 = 0.0567 = 5.67%
The cases for selecting the same coin are:
First penny: 5 possibilities over 21 coins: 5/21
Second penny: 4 possibilities over 20 coins: 4/20
P(selecting 2 pennies) = (5/21) * (4/20) = 20/420
First nickel: 7 possibilities over 21 coins: 7/21
Second nickel: 6 possibilities over 20 coins: 6/21
P(selecting 2 nickels) = (7/21) * (6/21) = 42/441
First dime: 9 possibilities over 21 coins: 9/21
Second dime: 8 possibilities over 20 coins: 8/21
P(selecting 2 dimes) = (9/21) * (8/21) = 72/441
P(selecting the same coin twice) = P(selecting 2 pennies) + P(selecting 2 nickels) + P(selecting 2 dimes) = (20+42+72)/441 = 0.3039 = 30.39%
The probabilities for picking 2 pennies either with or without replacement from a total of 21 coins is calculated. With no replacement, the chance is approximately 4.76%, while with replacement, it is approximately 5.67%. It's impossible to choose the same coin twice without replacement.
Explanation:The total number of coins is 5 pennies + 7 nickels + 9 dimes = 21 coins. We are asked to calculate the probability of selecting 2 specific coins from these total coins.
10. P(selecting 2 pennies), if no replacement occurs:
Since no replacement is occurring, we first select one penny out of 5, then another penny out of the remaining 4. That constitutes 5/21 * 4/20 = 0.0476, or 4.76% probability of selecting two pennies without replacement.
11. P(selecting 2 pennies), if replacement occurs:
Since replacement is possible in this scenario, even after choosing a penny, we still have 5 pennies left. Hence, the probability of selecting a penny twice is (5/21) * (5/21) = 0.0567, or approximately 5.67%.
12. P(selecting the same coin twice), if no replacement occurs:
If no replacement occurs, it's impossible to choose the exact same coin twice because once a coin is chosen, it is removed from consideration. Therefore, the probability here is 0.
