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.
Elaina ran 2.52 miles on Monday, 4.53 miles on Wednesday, and 3.45 miles on Saturday. What percent of the total miles did Elaina run on Monday?
Answers
To calculate the percent of total miles Elaina ran on Monday, add her running totals, find the fraction for Monday, and convert it to a percentage. Elaina ran 24% of her total weekly miles on Monday.
To determine what percent of the total miles Elaina ran on Monday, we first need to calculate the total number of miles she ran for the week. Then, we'll find out what fraction represents Monday's run in relation to the total, and finally convert that fraction to a percentage.
First, we sum up the miles:
Monday: 2.52 milesWednesday: 4.53 milesSaturday: 3.45 milesTotal miles = 2.52 + 4.53 + 3.45
Total miles = 10.50 miles
Next, we determine what fraction of the total distance was run on Monday:
Monday's fraction = Monday's miles / Total miles = 2.52 / 10.50
Finally, we convert this fraction to a percentage:
Monday's percentage = (Monday's fraction) x 100 = (2.52 / 10.50) x 100
Monday's percentage = 24% (rounded to the nearest whole percent)
Thus, Elaina ran 24 percent of her total weekly mileage on Monday.
Solve the system of equations for 7x+2y=16 and -21x-6y=24
Answers
7x + 2y = 16
Solving
7x + 2y = 16
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
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
Simplifying
x = 2.285714286 + -0.2857142857y

The probability of a certain hockey player making a goal after hitting a slap shot is 1/5. How many successful slap shot would you expect her to make after 120 attempts?
-5
-20
-24
-60
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.

calculate the area of a rectangle with an altitude of 30 cm and a diagonal of 50 cm
Answers
Given the diagonal and altitude of a rectangle, we can use the Pythagorean theorem to find the base. From there, multiply the base and altitude to find the area of the rectangle. In this case, the area is 1200 cm².
Explanation:The question is asking to calculate the area of a rectangle given the altitude (height) and the diagonal. We have two parameters, the altitude which is 30 cm and the diagonal which is 50 cm. From this, we can infer that the rectangle forms a right triangle with the altitude and the base being the two perpendicular sides and the diagonal being the hypotenuse. In this case, we can apply the Pythagorean theorem: base² = diagonal² - altitude².
Absolving, we find the value of the base of the rectangle: base = sqrt(50² - 30²) = 40 cm. The area of the rectangle can be calculated using the formula: Area = base x altitude = 40 cm * 30 cm = 1200 cm². Therefore, the area of the rectangle is 1200 cm².

It is essentially saying that WHAT power of 4(which is the base of log) gives us the value 64. You need to find the answer to that "WHAT."
Well
[tex]4^1 = 4 \\ 4^2 = 16 \\ 4^3 = 64[/tex]
Hence the answer is "3".

so log 64 base 4 = 3 >>> 4^3 = 64

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

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.
