Need help dont know how to round <br><br>round this number to the nearest thousand? 0.7966347977​
tatyana61 [14]

Answer:

.797

Step-by-step explanation:

If your talking about a decimal number, you would say the <u>thousandth</u>. I know, weird, but don't blame me.

To round up, any number above 5 rounds up to the next value place, and any number below 5 rounds down to the last value place.

Ex:   1.3483838383

Since 8 is greater than 5, we could get rid of all the 83s and just round up to 1.35.

So the thousandths place in a decimal would be 0.79<u>6</u>66357977, so we just ask if the next number after the thousandths place is greater than 5. The place number after .796 is 6, so since it is greater than 5, we would round up to .797.

Our answer is .797.

Hope this helps!

4) What is the present value of $4000 received at the
Bingel [31]

Answer:

$11040

Step-by-step explanation:

first of all the question says that $4000 were earned in a year and asks for what the new vale would be after the next 3 years with a discount rate of 8%.

If 1 year=$4000,then 3 years=$12000

100%-8%=92% (this happens because there is still a remaining amount that still has a cost to it),so 12000*92%=$11040

Direct variation or not a direct variation<br><br> y=5/x
MrRissso [65]

Answer:

not direct variation

Step-by-step explanation:

The equation for x and y in direct variation is

y = kx ← k is the constant of variation

y = \frac{5}{x} is not in this form, thus not direct variation.

The equation for x and y varying inversely is

y = \frac{k}{x} ← k is the constant of variation

y = \frac{5}{x} is in this form and represents inverse variation
