A recipe requires 1/3 cup of milk for each 1/4 cup of water. How many cups of water are needed for each cup of milk?

Vanyuwa [196]

Okay for this question, you make a simple equation: (1/3)x=(1/4)y to represent the ratio between the milk and water. Then to find how many cups of water are needed for each cup of milk, you plug in 3 for x (because 1/3 times 3 equals one cup) and solve for your y value. Your final equation for solving should look like: (1/3)(3)=(1/4)y

UkoKoshka [18]

Answer: $w=\dfrac{V}{lh}$

Step-by-step explanation:

Given: The formula for the volume V of a rectangular prism is V = ℓwh, where ℓ represents the length, w represents the width, and h represents the height.

We rearrange this formula by dividing ℓh both sides of the formula to get the new formula for the width of the rectangular prism, we get'

$w=\dfrac{V}{lh}$

Hence, the new formula for the width of the rectangular prism. :

$w=\dfrac{V}{lh}$

The weather satellite shows that hurricane George is 1,728 kilometers southeast of Puerto Rico and moving northwest at 24 kilome

jenyasd209 [6]

Answer:

1. 3 days.

Step-by-step explanation:

We have been given that the hurricane George is 1,728 kilometers southeast of Puerto Rico and moving northwest at 24 kilometers per hour.

First of all we will find the number of hours it will take for George to reach Puerto Rico. We can find number of hours taken by hurricane George to reach Puerto Rico by dividing 1728 by 24.

$\text{Time}=\frac{\text{ Distance}}{\text{ Speed}}$

$\text{Time taken by hurricane George to reach Puerto Rico}=\frac{1728}{24}$

$\text{Time taken by hurricane George to reach Puerto Rico}=72$

We can see that George will reach Puerto Rico in 72 hours. Let us convert hours to days by dividing 72 by 24 (number of hours in a day).

$\text{Days taken by hurricane George to reach Puerto Rico}=\frac{72}{24}=3$

Therefore, the hurricane George will reach to Puerto Rico in 3 days, if the hurricane stays on its present course. Our first option is the correct choice.
