Is the value of the 1 in 1,440,000 10 times as great as the value of the 4 in the hundred thousands place?

Answers

If you multiply 400,000 by 10 you get 4,000,000. This means that, yes, the value of the 1 is 10 times the 4 in the hundred thousands place. 
Hope I helped :)
Final answer:

The value of the 1 in the number 1,440,000, which is in the million's place, is 2.5 times greater than the value of the 4 which is in the hundred thousand's place.

Explanation:

The value of the 1 in the number 1,440,000 is in the millions place, thus it represents 1,000,000. The 4 on the other hand, is in the hundred thousands place, and thus represents 400,000. The value of the 1 is therefore not just ten times the value of the 4, but in fact, it is 2.5 times greater.

Here is the process: value of 1 = 1,000,000, value of 4 = 400,000, so 1,000,000 / 400,000 = 2.5. Therefore, the value of 1 is 2.5 times the value of 4.

Which is the better buy 3 pounds for 8.31 or 5 pounds for 12.95

Answers

answer:

5 pounds for 12.95

explanation:

to solve, find the unit rate. the cheaper unit rate is the best and cheapest choice.

8.31/3 = 2.77
12.95/5 = 2.59

5 pounds for 12.95 is the cheaper choice because it has a smaller unit rate.

Hope this helps! :D
It'd be better to buy the 5 pounds for 12.95.

If you divide the price by the amount, it results as 2.59 as opposed to 3 pounds for 8.31 which is 2.77 per pound, making it clear now that the 5 lb for 12.95 is the better deal

Find the percent error of the measurement 7 cm.

Answers

The answer is 7.14 :)

Answer:

The percent error of the measurement 7 cm is 7.14%.

Step-by-step explanation:

Given : Measurement 7 cm

To find : The percentage error of the given measurement.

Solution :

First we find the error in the measurement.

Measuring to the nearest centimeter means the true value could be up to half a meter smaller or larger.

i.e It is upto 0.5 (between 6.5 and 7.5)

Measurement - 7 ±0.5 cm

Absolute Error = 0.5 cm  

Relative Error = [tex]\frac{0.5}{7}=0.0714[/tex]

Percentage Error =  [tex]0.0714\times 100=7.14\%[/tex]

Therefore, The percent error of the measurement 7 cm is 7.14%.
