Arecipe uses 3 cups of flour and 2 cups of sugar. imagine the recipe is doubled and that 4 cups of sugar are used. use the unit rate in part a (1.5) to find how much flour is needed if the recipe is made with 4 cups of sugar

6 cups of flour

Step-by-step explanation:

A recipe uses 3 cups of flour and 2 cups of sugar.

The ratio of flour to sugar is 3:2

For every 2 cups of sugar uses 3 cups of flour.

Now we find how much cups of flour uses for unit cup of sugar.

For 1 cup of sugar uses cups of flour.

We need to calculate number of cups of flour used with 4 cups of sugar.

As we know,

Unit cup of sugar = cups of flour

4 cups of sugar = cups of flour

                           = 6 cups of flour

Hence, 6 cups of flour is needed to make a recipe with 4 cups of sugar.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
