How many pounds is a quarter of a ton?

Answers

Answer 1
Answer: there is 500 because there is 2000 in a ton and 1/4 of 2000 is 500
Answer 2
Answer: There are three major units called tons. 

1 US (short) ton = 2000 lb so one fourth is 500 lbs. 
1 UK (long) ton = 2240 lb; one fourth is 560 lbs. 
1 tonne (metric) = 2204.6 lb; one fourth is 501.15 lbs.

Representation of Data with Plots Using graphing software of your choice, create a scatter plot of your data. Predict the line of best fit, and sketch it on your graph. Copy and paste your scatter plot into a word processing document. 2. The Line of Best Fit Include your scatter plot and the answers to the following questions in your word processing document: Which variable did you plot on the x-axis, and which variable did you plot on the y-axis? Explain why you assigned the variables in that way. Write the equation of the line of best fit using the slope-intercept formula y = mx + b. Show all your work, including the points used to determine the slope and how the equation was determined. What does the slope of the line represent within the context of your graph? What does the y-intercept represent? Test the residuals of two other points to determine how well the line of best fit models the data.

Answer:

The correct answer is B. 10x - 12y

Step-by-step explanation:

To find this, we focus on just the like terms. So we break it down by the variable each time.

5x + 5x = 10x

-6y + -6y = -12y

z + -z = 0

So we put those answers all together to get 10 - 12y + 0 or just 10x - 12y

At a music store, the price of a set of speakers is $245, plus the sales tax of 6.5%. What is the total cost of the speakers, including the sales tax?

Answers

In order to find out what the additional value of the sales tax would be,which is 6.5%, you have to find 1% of $245. Which is $2.45. As you're looking for 6.5%, you have to multiply $2.45 by 6.5, which gives you $15.93 (rounded). In order to find the cost including the sales tax, you have to add $15.93 to the original price of $245, which gives you $260.93.Therefore, the price of the speakers, including a sales tax of 6.5% is $260.93Hope this helps :)
So,

The total cost = cost + sales tax

cost + sales tax = x or total cost

1. cost = $245

2. sales tax = 0.065(cost)

245 + 0.065(cost) = x

Simplify
245 + 15.925 = x

Round to the nearest hundredth
245 + 15.93 = x

Collect Like Terms

260.93 = x

The total cost of the speakers, including tax, is $260.93.

a proportional relationship is a liner relationship because the rate of change is constant (and equal to the constant of proportionality ).what is required of a proportional relationship that is not required of a general line relationship?

Answers


If you graph a proportional relationship, the graph must
go through the origin.  Because if the relationship is
really proportional, then when one of the quantities
is zero, the other one is also zero.
