Answer:
its i think the first one and the last one
Step-by-step explanation:
sorry if its wrong but i think it is right
I need the equation to be able to help
We are given expression: 
Let us distribute 3/8 over exponents in parenthesis, we get
We can get x and y out of the radical because, we get whlole number 1 for x and y exponents for the mixed fractions.
So, we could write it as.
Now, we could write inside expression of parenthesis in radical form.
![xy\sqrt[8]{2x^{3}x^4y^7}](https://tex.z-dn.net/?f=xy%5Csqrt%5B8%5D%7B2x%5E%7B3%7Dx%5E4y%5E7%7D)
Answer: 4166.67$
Step-by-step explanation:
1920 x 250 = amount
Amount = 120%
Cost price = 100%
1920 x 250= 120%
Cost price = 100%
Cross multiply and divide both side by 120
1920 x 250 x 100/120 = price
Exchange rate = cost in #/cost in $
= (1920 x 250 x 5/6)/(5000)
= (96 x 5/6) = 16 x 5= 80
Exchange rate then was 80 to 1$
The sales will be 400000/96 = 4166.67$
After the division, we get 8.99031476998. This rounds to <u>9</u> as a whole number, which is the answer.
When rounding to a whole number, the digits following the decimal decide what number it rounds to. If it is 0-4 it rounds to whatever the whole number currently is E.G.
8.1 would round to 8
But if its 5-9 it rounds to one above, like in our current case.
8.5 rounds to 9.
42.414 rounds to 42.
42.94149124 rounds to 43.
