So what have you done towards answering this?

Hi Grace,

3cm = 500feet

so

1cm= 500/3 feet

so

3.5cm = 500/3  *  3.5  feet

Make sure you understand then you can finish it.

Thanks for the feedback :)

And you are welcome. 

When the same constant is added to the numbers 60, 100, and 160 a three-term geometric sequence arises. What is the common ratio of the resulting sequence?

\(\frac{100+n}{60+n}=\frac{160+n}{100+n}\\ (100+n)^2=(60+n)(160+n)\\ 10000+n^2+200n=9600+n^2+220n\\ 400=20n\\ n=20\\ \)

so the sequence is    80,120, 180

120/80 = 3/2

180/120=3/2

Common ratio is 3/2

I have responded on the original question.

I don't think this question makes sense.

Each child can choose any of the three flavours.

The only time this is not true is if the child is the last or second last child to get a scoop and not all the flavours have been chosen yet.

Really, I do not think that the meaning of the question is discernible

I saw this same question answered ealier today.

Take a look for it.

It takes 830 bricks to construct a wall that measures 14 feet 9 inches long and 6 feet high.   

14*0.75*6= 63 feet square.

It takes 830 bricks to construct a wall that is 63 feet square

The crew you hire can lay 300 bricks/hour.

The cost of the labor is $4,000 per eight-hour workday and you can pay for a partial day.

You need to build a wall 36' 6" long and 6' high.    36*0.5*6 =  108 square meters

How much will the new wall cost?

Ok what do we have here.

\(\frac{830bricks}{63 feet square}\:,\qquad \frac{300bricks}{1 hour}\;,\qquad \frac{8hours}{1day}, \;\qquad \frac{$4000}{1day} \;,\qquad 108squarefeet\\~\\ \text{and you want the price in dollars}\\ \text{ I have to start with dollars on the top and put the others in order so that the other units all cancel out}\\ \text{like this}\\~\\ \frac{$4000}{1day}\times \frac{1day}{8hours}\times \frac{1hour}{300bricks}\times \frac{830bricks}{63square feet}\times108squarefeet\\~\\ =\$\frac{4000*830*108}{63}\\ =$5691.43 \)

I could easily have made a careless error but the method is sound.
