Suppose you are trying to find your longitude
Alex73 [517]

Answer: 5:15:23 pm

Step-by-step explanation:

There are different time zones in the world due to the Earth's rotation as this results in different parts of the Earth receiving sunlight at different times.

GMT is used as a basis to find the times of other zones.

In this instance, EDT time is -4 that of GMT.

This means that EDT is 4 hours behind GMT.

Time in GMT is therefore:

=  1:15:23 + 4 hours

= 5:15:23 pm

one batch of cookies makes 24 cookies. the recipe calls for 1 3/4 cups of flour. if Sarah needs to make 60 cookies how much flou
Svetllana [295]

Answer:

4 3/8 cups of flour needed for 60 cookies

Explanation:

You can multiply 24 by 2.5 to get 60 so you'd multiply the cups of flour by 2.5 as well. You multiply both of them by the same number because it's a ratio. You'd multiply then simplify to get the answer 4 3/8 cups of flour.
