Markes recipe for 24 cookies calls for 2½ cups of flour.How much flour will markes need to make 60 cookies?​
Ronch [10]

Answer:

6 1/4 cups of flour

Step-by-step explanation:

24/2 = 12

2.5/2 = 1.25

12 x 5 = 60

1.25 x 5 = 6.25 cups

For every 24 cookies Markes needs 2.5 cups of flour. So, for 12 cookies he needs half of that which is 1.25 cups. 12 is a fifth of 60, so we multiply 1.25 by 5 which gives us 6.25 cups of flour. :D

If f(x)= sqrt4x+9+2, which inequality can be used to find the domain of f(x)?
Papessa [141]

Answer:

The inequality would be 4x + 9 ≥ 0

Step-by-step explanation:

You could use this inequality to solve the domain as any number can be put into this equation as long as it doesn't make what is under the square root symbol (4x + 9) negative. Therefore, you can build this inequality and solve from there if you would like.
