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?
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 kmNext, 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

what scale factor is used to create a scale 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.
if a tablet contains 750mg, how many gram will the patient take if the tablet is broken in two?
Half of a 750mg tablet is 375mg, which converts to 0.375g. This is calculated by dividing the milligram amount by 1000.
Explanation:If a tablet contains 750mg, and the tablet is broken in two, each half would contain half the amount of the original tablet. Since 750mg is equivalent to 0.75g, breaking the tablet in half would result in two halves, each with a mass of 375mg, or 0.375g. To convert from milligrams to grams, we use the conversion factor that 1 gram is equal to 1000 milligrams. Therefore, we divide the milligram amount by 1000 to get the equivalent in grams.
Example: If you have 375mg of a substance and want to convert it to grams, you would calculate 375mg ÷ 1000 = 0.375g. Thus, when the patient takes half of a 750mg tablet, they are taking 0.375g of the medication.
A soccer team played 28 games and won 4 out of every 7 games. There are no ties.
how many games did they lose?
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
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.

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

Step-by-step explanation:
at the market you can buy 5 bags of apples for 23.60 at the orchard you can get 7bags of apples for 32.76 which is the better deal?
The orchard offers the better deal with a price per bag of $4.68 compared to the market's price per bag of $4.72. We arrived at this conclusion by dividing the total cost by the number of bags at each location.
To determine which is the better deal for the bags of apples, we need to calculate the price per bag at the market and at the orchard. At the market, 5 bags of apples cost $23.60, so to find the price per bag, we divide $23.60 by 5.
Price per bag at market = $23.60 / 5 = $4.72
At the orchard, 7 bags cost $32.76, so we divide $32.76 by 7 to find the price per bag.
Price per bag at orchard = $32.76 / 7 = $4.68
Since the price per bag at the orchard is less than the price at the market, the orchard offers the better deal.

in week 1, the total sales for a video game were 2,374,136. What percent of the total sales were from the us? round to the nearest whole percent
To find the percentage of sales from the US out of the total sales for a video game, divide the number of sales from the US by the total sales and multiply by 100. Rounded to the nearest whole percent, the answer is 8%.
Explanation:In order to find the percentage of total sales that were from the US, we need to know the sales specifically from the US. From the given options, let's consider option c, which states that 67,092 out of 823,356 sales were from the US. To find the percentage, we can divide the number of US sales (67,092) by the total sales (823,356) and multiply by 100. This gives us (67,092/823,356) * 100 = 8.147%. Rounding to the nearest whole percent, the answer is 8%.

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?
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.
