aliya0001 [1]

Answer: Use 1.75 cups of blue and 1 cup of yellow

Step-by-step explanation:

The given problem can be placed in the category of ratios and proportions. There is a ratio of color mixing which contains the proportion of two colors i.e blue and yellow. When we use 2 cups of yellow with 3.5 cups of yellow then we get green color so if we mix half of their amounts then we can get less or simply half amount of color too.

pashok25 [27]

Answer:

6.21\times 10^{-5}\ \text{light years}

Step-by-step explanation:

The distance light travels in one year is known as a light year.

1\ \text{light year}=5.87\times 10^{12}\ \text{miles}

The closest that Earth ever gets to Jupiter is 3.65\times 10^8\ \text{miles}

3.65\times 10^8\ \text{miles}=\dfrac{1}{5.87\times 10^{12}}\times 3.65\times 10^8\ \text{light years}\\\\=6.21\times 10^{-5}\ \text{light years}

Hence, the distance it will take light to travel from Earth to Jupiter at this distance is 6.21\times 10^{-5}\ \text{light years}
