What is the answer to this
deff fn [24]
So the first column is if a serving is 36 so all you have to do is divide all the different ingredient amounts by three and that will tell you the answer for the serving of 12 row because 12 * 3 = 36

and for the 24 row just multiply all the numbers you get in the 12 row and that will be the answer cause 12 * 2 = 24 

then what ever numbers you get on the 12 serving column just divide those by 12 and that will tell you how much you get for one serving and that will help you solve for the 60 one and the 300 one all you have to do it times the numbers by 60 and then 300

The conservation club has 32 members. There are 18 girls in the club.
guapka [62]
The amount of girls in the club is 18 out of the 32 members.
To find the amount of boys there, we subtract 18 out of 32
32 - 18 = 14
so there are 14 boys in the club

Now to find the ratio of girls to boys...
18/14
simplified to 9/7 (option D.)

Hope this helps :)

to fill a coffee mug at a local shop costs $2.50. the shop sells coffee beans foe $12 per pound. each pound makes enough coffee
myrzilka [38]

Answer:

There are a few possible answers so read explanation, but the one I will put up here is:

20.83

Step-by-step explanation:

First you have to find how much 100 cups of coffee costs in store.

To do this you will multiply 2.50 by 100 and get 250. So now we know 100 cups of coffee in store costs $250 whereas 100 cups at home is $12.

To find how many times greater the price in store is compared to the at home brew, you have to divide 250 by 12 and get 20.8333333....

We don't stop there though, because it asks us to approximate. I am not sure what it would like us to round to, but here are some possible approximations:

  1. 20.83
  2. 20.8
  3. 21

Any of those re reasonable approximations, you choose whichever you think the question wants, or whatever your teacher asks for.

Hope this helps
