At the end of 2005, the national debt of the U.S. was about 10^12 dollars, and the population of the U.S. was about 10^8. About how much was the per capita ( per person ) debt?
Answers
According to your numbers, you use debt/American population.
10^12 / 10^8 = 10,000
Put it into your calculator as
1 *10 y^x or ^ or x^y 12 ÷ 1 * 10^8 = and it should bring back 10000.
That number is quite low. The American Federal Debt is now 21 000 000 000 000 and there are 330 000 000 Americans currently living on the planet. That means the debt is 63,600 for every man woman and child now in the US: each one of them owes this much. Most countries in the western world are no better off. Russia is the only country I know of that does not have a currency problem.
Javier’s fuel tank holds 12 3⁄4 gallons of gasoline when completely full. He had some gas in the tank and added 10.3 gallons of gasoline to fill it completely.
How many gallons of gasoline were in the tank before Javier added some?
Answers
The number of gallons of gasoline in the tank before Javier added some is 2 3/4 gallons.
1. Subtract 10.3 gallons (the amount he added) from 12 3/4 gallons (the total capacity of the tank).
2. Calculate 12 3/4 - 10.3 to find the remaining amount of gasoline in the tank.
To subtract mixed numbers, we first convert them into improper fractions:
[tex]\[ 12 \frac{3}{4} - 10 \frac{3}{10} \][/tex]
[tex]\[ = \frac{(12 \times 4) + 3}{4} - \frac{(10 \times 10) + 3}{10} \][/tex]
[tex]\[ = \frac{48 + 3}{4} - \frac{100 + 3}{10} \][/tex]
[tex]\[ = \frac{51}{4} - \frac{103}{10} \][/tex]
To subtract fractions, we need a common denominator. Here, the least common denominator (LCD) is 20.
[tex]\[ = \frac{51 \times 5}{4 \times 5} - \frac{103 \times 2}{10 \times 2} \][/tex]
[tex]\[ = \frac{255}{20} - \frac{206}{20} \][/tex]
[tex]\[ = \frac{255 - 206}{20} \][/tex]
[tex]\[ = \frac{49}{20} \][/tex]
Now, we convert the improper fraction back to a mixed number:
[tex]\[ = 2 \frac{9}{20} \][/tex]
Therefore, Javier had 2 9/20 gallons of gasoline in the tank before adding more.
Javier had 2.45 gallons of gasoline in his tank before he added 10.3 gallons to fill it to its full capacity of 12.75 gallons.
To find how many gallons of gasoline were in Javier's tank before he added some, we need to subtract the amount he added from the total capacity of the tank. Javier's fuel tank can hold 12 3/4 gallons when full, which is equal to 12.75 gallons. He added 10.3 gallons to fill it up. Therefore, the amount of gas in the tank before he added more can be calculated as follows:
Amount of gasoline initially in the tank = Total capacity - Amount added
Amount of gasoline initially in the tank = 12.75 gallons - 10.3 gallons
Amount of gasoline initially in the tank = 2.45 gallons
Thus, Javier had 2.45 gallons of gasoline in the tank before he added the 10.3 gallons.

Billy left home at 9:00 a.m. and rode his bike to the park at an average speed of 10mph. He arrived at the park at 9:30. How many miles from the park is Billy’s house.
Answers
The solution is:
Park is 5 miles from Billy's home.
What is speed?Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Speed = Distance/ Time.
Given:
Billy left home at 9 a.m. And rode his bicycle to the park at an average speed of 10 miles per hour here and got the park at 9:30 a.m.
Now, to find the distance from park to Billy,s home.
Time it took Billy to rode his bicycle from park to home is from 9.30 a.m to 9.30 p.m.
So, the time = (9.30 - 9.00) = 30 minutes
Speed = 10 miles per hour.
Now, to get the distance from park to Billy's home we put formula:
Speed = Distance/ Time.
so, we get,
Distance = 10 * 0.5
= 5
Therefore, park is 5 miles from Billy's home.

To solve this system of equations by elimination, what operation could be used to eliminate the y-variable and find the value of x? 2x − 4y = 6 −3x + 3y = 12
Answers
To eliminate the y-variable in the given system of equations and find the value of x, you can multiply the first equation by 3 and the second equation by 4 to make the coefficients of y equal. Then, add the two equations together to eliminate the y-variable. Finally, solve for x.
Explanation:To eliminate the y-variable and find the value of x in the given system of equations, we can multiply the first equation by 3 and the second equation by 4 to make the coefficients of y in both equations equal. This will allow us to eliminate the y-variable when we subtract the two equations.
Multiplying the first equation by 3, we get: 6x - 12y = 18
Multiplying the second equation by 4, we get: -12x + 12y = 48
Now, we can add the two equations together, and the y-variable will cancel out: (6x - 12y) + (-12x + 12y) = 18 + 48
Simplifying, we have: -6x = 66
Dividing both sides by -6, we find: x = -11
Therefore, the value of x is -11.
Final answer:
To eliminate the y-variable and find the value of x in the system of equations, we can use the method of elimination. We can multiply the equations by coefficients to create opposite coefficients for the y-terms, which will cancel each other out when added together. The resulting equation can then be solved to find the value of x.
Explanation:
To eliminate the y-variable and find the value of x, we can use the method of elimination. In this case, we need to multiply the two equations by coefficients that will create opposite coefficients for the y-terms so that they will cancel each other out when added together. Let's multiply the first equation by 3 and the second equation by 4:
6x - 12y = 18
-12x + 12y = 48
Adding these two equations eliminates the y-variable:
-6x = 66
Solving for x, we divide both sides by -6:
x = -11

7x + 2y + -2y = 16 + -2y
Combine like terms: 2y + -2y = 0
7x + 0 = 16 + -2y
7x = 16 + -2y
Divide each side by '7'.
x = 2.285714286 + -0.2857142857y

I need help with Getting the answer! Help please!
Answers
Answer: 24
We know that the probability of a certain hockey player making a goal after hitting a slap shot is [tex]\frac{1}{5}[/tex].
We need to figure out the number of successful slap shots if she makes 120 attempts?
Since the player is able to make a goal once out of 5 attempts. Therefore, in order to find the number of goals that we can expect the player to make successfully if she attempts 120 slap shots we will multiply the probability with 120.
Number of successful goals = (Probability of making one goal)x(Number of attempts)
Number of successful goals = [tex]\frac{1}{5}\times 120 = 24[/tex].
Therefore, player will be able to make 24 goals out of 120 attempts.

Answer : D 10
The stem and leaf plot below shows the number of points scored in each basketball game a team played during a season
From the stem and leaf plot , We have 4 leaf for the stem 4
so the scores are 44, 45, 48, 49
Question says more than 40 points scored. so we consider stem 5 and 6 as well
61, 66, 67
5 2, 52, 58
So total 10 scores
There were 10 games in which the basketball team scored more than 40 points.
The stem and leaf plot provided shows the scores of a basketball team across different games. To find out in how many games more than 40 points were scored, we should look for leaves attached to stems of '4' or higher, since the stems represent the 'tens' place and the leaves represent the 'ones' place in a score.
In the stem '4', we have leaves '4', '5', '8', and '9', which correspond to the scores 44, 45, 48, and 49, respectively. Moving up to the stem '5', we have leaves '2', '2', and '8', which translate to the scores 52, 52, and 58. Finally, the stem '6' with leaves '1', '6', and '7' represents the scores 61, 66, and 67.
Adding all the games with scores over 40 points together, we get a total of 4 (from the '4' stem) + 3 (from the '5' stem) + 3 (from the '6' stem) = 10 games.
