how old is the expanded notation method work

Answers

Answer 1
Well, 
For example 

2.34 * 10^6 will be....
2,340,000
It is because if you have the positive powers, you move your decimal to the right. In this case the power is 6 so you move your decimal to the right 6 times. 
Here's another example

1.23 X 10^-2 
The answer will be 0.0123 because you move your decimal two the left two times. The power is negative 2 so you move it to the left.

Final tips: If you have positive power, move it to the right and if you have negative power, move it to the left.

what scale factor is used to create a scale drawing

Answers

The answer depends on how big you want the drawing to be and how big the actual object is. If the object is in feet, for example 7 feet tall then you could do the scale drawing at a 1ft to 1in ration making the drawing 7 inches tall. There are a lot of factors to know in order to figure out the ratio or scale factor you should use when making a drawing.

A scale factor is a dimensionless number used to accurately represent the real-life measurements of an object on a smaller scale in a drawing or model.

The scale factor is used to create a scale drawing is a dimensionless number which represents the ratio of the drawing's dimensions to the actual dimensions of the object. For example, if the scale factor is 1:50, this means that 1 unit in the drawing is equal to 50 units in real life.

When creating a scale model, map, or drawing, you use the scale factor to accurately represent larger objects on a smaller, manageable scale. You would multiply the real measurements by the scale factor if you're scaling down, or divide the drawing measurements by the scale factor if you're scaling up.

There are some hats in a box. 1/6 of them are red, 1/3 of blue, and 3/7 of the remainder are green. If there are 27 green hats, how many hats are there altogether

Answers

1/6 are red and 1/3 are blue 
that means 1/6 + 2/6 = 3/6 = 1/2 are either red are blue 
3/7 of the remainder is 3/14 of the total 
3/14 x = 27 
x = 27(14/3) = 126 

there are 126 caps 
126 / 6 = 21 are red 
126 / 3 = 42 are blue 
there are 63 left, of which 3/7 are green 
3/7 (63) = 27 ==> 27 green caps 

total of 126 caps

Colby graphed a scatter plot of student exam scores (y) and the number of hours each student had slept the night before the exam. She drew the trend line and calculated its equation to be y=9/2x + 60. What is the predicted score for a student who slept 6 hours the night before the exam?

Answers

y=9/2•6+60
y=27+60
y=87

To predict the exam score for a student who slept 6 hours, substitute 6 for x in the trend line equation y=9/2x + 60, which calculates to 87.

The question asks to predict the exam score for a student who slept 6 hours before the exam using the given trend line equation y=9/2x + 60. To find the predicted score, we substitute the number of hours (x = 6) into the equation:

[tex]y = {9}/{2}~times ~6 + 60[/tex]

This simplifies to:

y = 27 + 60

So, y = 87

Therefore, the predicted exam score for a student who slept 6 hours is 87.

The school wants to buy a new speaker system for the football stadium with the money they raised from the bake sale. They compared speaker system prices from two different distributors.

From Schools'R'Us, a system, t, costs $280 less than three times the price of the same speaker system, d, at The Warehouse. The difference in price between the speaker system at Schools'R'Us and The Warehouse is $288.

What system of equations can be used to determine the price of the speaker system at each distributor?

Answers

The system of equations to determine the price of the speaker system at each distributor is t = 3d - 280 and t - d = 288. Solving these equations will give the prices at Schools'R'Us (t) and The Warehouse (d).

To find the price of the speaker system at each distributor, we need to set up a system of equations based on the information provided. Let's denote the cost of the speaker system at Schools'R'Us as t, and the cost of the same speaker system at The Warehouse as d.

According to the problem statement, we have the following relationship between the two prices:
t = 3d - 280. (1)

The difference in price between the two systems is also given as $288, forming the second equation:
t - d = 288. (2)

Therefore, the system of equations that we can use to determine the price of the speaker system at each distributor is:

t = 3d - 280t - d = 288

Solving this system of equations will provide the values for t and d, representing the prices of the speaker systems at Schools'R'Us and The Warehouse, respectively.

A soccer team played 28 games and won 4 out of every 7 games. There are no ties.
how many games did they lose?

Answers

Answer:

They went 16-12 16 wins 12 losses.

Step-by-step explanation:

28 games, 4/7 are wins.

28/7=4

4*4=16 makes 16 wins

28-16=12 so 12 losses are the remaining games

Final answer:

To find the number of games lost, subtract the number of games won from the total number of games played. If the team won 4 out of every 7 games, they would lose 3 out of every 7 games. Therefore, the team lost 12 games.

Explanation:

To find the number of games lost, subtract the number of games won from the total number of games played. In this case, the team won 4 out of every 7 games. So, they lost 3 out of every 7 games. To calculate the number of games lost, multiply the number of sets of 7 games by 3.

For example, if the team played 28 games, there are 4 sets of 7 games. Therefore, the team lost 3 x 4 = 12 games.

Mr. Alan drove 2 1/5 hours at a speed of 70 kilometers per hour. He then drove another 224 kilometers. He took 5 hours for the whole journey. What was mr alan average speed for the whole journey?

Answers

Final answer:

To find the average speed for the whole journey, calculate the total distance traveled and total time taken. The average speed for Mr. Alan's whole journey is 75.6 km/h.

Explanation:

To find the average speed for the whole journey, we need to calculate the total distance traveled and the total time taken. First, calculate the distance traveled during the 2 1/5 hours at a speed of 70 kilometers per hour:

Convert 2 1/5 hours to a mixed number: 2 1/5 = 11/5 hoursMultiply the time by the speed: 11/5 hours * 70 km/h = 154 km

Next, calculate the total distance traveled by adding the distance from the first part (154 km) to the additional distance of 224 km: 154 km + 224 km = 378 km

Finally, calculate the average speed for the whole journey by dividing the total distance by the total time taken: 378 km / 5 hours = 75.6 km/h

The sum of the measures of the exterior angles of the decagon is ????

Answers

Fora any regular polygon, all of the exterior angles must add to 360

In a decagon, each exterior angle is 36° (360/10=36)

Final answer:

The sum of the measures of the exterior angles of a decagon is 360 degrees, as this is true for the exterior angles of any polygon.

Explanation:

The sum of the measures of the exterior angles of any polygon, including a decagon, is always 360 degrees (°).

This is because the exterior angles, one at each vertex, effectively 'walk around' the entire polygon, forming a complete circle.

For a decagon, which is a ten-sided polygon, despite having ten different exterior angles, when added together, they will sum up to 360°.
