James earned $25 selling lemonade. If 80% of this was profit, how much did james spend initially on ingredients?
Y_Kistochka [10]
Set the equation to look like

20/100 = x/25

Then multiply to get 

500 = 100x
500/100 = x
5 = x

Therefore James spent 5 dollars initially on ingredients.

This is on the constant of proportionality from a table...
ZanzabumX [31]

The correct answer is 8.3 repeated.

25 divided by 3 is 8.3 repeated and so is the rest so it is obvious to say that 8.3 repeated is the correct answer.

A submarine travels 8.3 km due North from its base and then turns and travels due West for 13.9 km.
olga_2 [115]

Answer:

He is 5.6 km away

Step-by-step explanation:

he starts traveling away from base and is 8.3 km away to start with

then he turns west and travels 13.9 km away

what this mean is that you have to subtract the distance he turned from the distance he started off with

ex: 13.9 - 8.3 = 5.9

to get your answer of how far away he is from the base

What is the sum of the first five terms of s geometric series with a1=6 and r=1/3
omeli [17]

S_{5} = \frac{242}{27} = 8 \frac{26}{27}

The sum of n terms in a geometric series is

S_{n} = \frac{a(1-r^n)}{1-r}, hence

S_{5} = \frac{6(1-(1/3)^5)}{1-1/3}

                        = \frac{6(1-1/243)}{2/3}

                        = 9 ( \frac{242}{243}) = \frac{242}{27}
