Answer:

  • 120 km/h

Step-by-step explanation:

  • Speed in one direction = 40 km/h
  • Speed on return = x
  • Average speed = 60 km/h

Let the distance be d

<u>Average speed </u>

  • 2d/(d/40 + d/x) = 60
  • d/40 + d/x = 2d/60
  • 1/40 + 1/x = 1/30
  • 1/x = 1/30 - 1/40
  • 1/x = (4-3)/120
  • 1/x = 1/120
  • x = 120 km/h

two decimal numbers have digits to the thousands place if you multiply them how many digits do you expect there to be after the
disa [49]

There will be 6 decimal digits in the product of the numbers and can be fewer than 6.

<h3>What are decimal numbers?</h3>

A decimal number has a whole number and a fractional part.

Given that the two decimal numbers have digits to the thousandth place.

Therefore, there are three digits after the decimal point.

The number of digits after the decimal point in the product of two decimal numbers is the sum of the digits after the decimal point in both numbers.

Let the first number be 0.001 and the second number be 0.002.

Then, the number of decimal digits in the product of 0.001 and 0.002 will be 6.

If the two numbers are 0.005 and 0.002, then surely, there will be less than 6 digits after the decimal as the last 0 can be omitted in counting.

Hence, there will be 6 decimal digits in the product of the numbers and can be fewer than 6.

In an investment account what if $2000 is invested. What is the value after 3 years if compounded monthly by 6% ?
OleMash [197]
<span>
Compound interest formula  A = P(1 +r/100)^n
A = Amount
r = rate = 6
n = number of compounding time.
P = Principal = $2000.
Since we are compounding monthly, r = 6% p.a = (6/12)% per month.
n= 3 years = 3*12 = 36 months.
Note that  since we are compounding monthly, our time would be in months.
A = P(1 +r/100)^n
A = 2000 * (1 + (6/12)/100 )^36
A = 2000 * (1 +  6/1200)^36
</span><span>A = 2000 * (1 +  0.005)^36    Use your calculator</span>
<span> <span>A = 2000 * (1 .005)^36</span> = 2393.36
Amount = $2 393.36</span>
That's it. Cheers.

Which is a feature of a traditional IRA? There is no age limit for contributions. You can contribute until you're 70.5 years old
Crank
Hey there!

For a traditional IRA, you can only contribute until you're 70 and a 1/2 years old. There's no minimum age requirement to make any IRA contributions, but you must have a regular income that equals or exceeds your contribution. 

Hope this helped you out! :-)
