Melisa used 0.6kg of red sand to make a mural on the wall. She added 250g of blue sand to it. Finally she added 500g of white sand to half of the mixture. Find the mass of the mixture that has white sand in it.

Express your answer in kilogram

06 kg of red + 250 g of blue

= 1100 g of mixed sand

1/2 of that is 550g
she adds 500 g of white to that, so
total stuff with white sand in it is 1050 g or 1.05 kg

To find the mass of the mixture that has white sand in it, we need to calculate the mass of the red sand, blue sand, and the mixture with white sand.

First, let's convert grams to kilograms since the answer should be in kilograms.

Given:
Mass of red sand = 0.6 kg
Mass of blue sand = 250 g
Mass of white sand added to half of the mixture = 500 g

To convert grams to kilograms, divide the mass by 1000:
Mass of blue sand = 250 g ÷ 1000 = 0.25 kg
Mass of white sand = 500 g ÷ 1000 = 0.5 kg

To calculate the mass of the mixture with white sand, we need to consider that half of the mixture has white sand. So, the mass of the mixture is the sum of the mass of red sand, blue sand, and half the mass of white sand.
Mass of mixture with white sand = Mass of red sand + Mass of blue sand + (0.5 × Mass of white sand)
Mass of mixture with white sand = 0.6 kg + 0.25 kg + (0.5 × 0.5 kg)
Mass of mixture with white sand = 0.6 kg + 0.25 kg + 0.25 kg
Mass of mixture with white sand = 1.1 kg

Therefore, the mass of the mixture that has white sand in it is 1.1 kilograms.
