Answer: 30,000 months or 2,500 years

She'd better start saving more haha.

Step-by-step explanation:

Goal=4.2x10^6\\Savings/month=1.4x10^2

\frac{4.2x10^6}{1.4x10^2} =(\frac{4.2}{1.4})x10^(^6^-^2^)=(3)x10^4=3x10^4 =30000 months=\frac{30000}{12}=2500years

Is the value of the first 4 ten times as great as the value of the second 4 in 4,043? Explain. What can you generalize about the
Ira Lisetskai [31]

As per the the question we need to calculate the value of first 4 multiplied by 10.

Now in the number 4,043, the first 4 is at the thousands place. So the place value of first 4 in the digit 4,043 is 4000.

Multiplying the value of first 4 by 10 we get:

4000 \times 10=40,000

Now, the second 4 in the digit 4,043 is at the tens place. So the place value of second 4 in the digit 4,043 is 40.

We can see that two of them are not equal and the value of first 4 times ten is far greater than the value of second 4.

It can be said that two of the 4s in the digit 4,043 are at two different places, first is at thousands place and second is at tens place. So if the numbers are two places apart their place value will have difference of 100 folds.
