A jar contains 0.75 liter of blackberry juice and 0.60 liter of blueberry juice. Patrick poured 0.25 liter of guava juice into the jar. He then drank 0.20 liter of the mixture. Write an expression to represent the total amount of juice left in the jar. Simplify the expression and identify which property is used in each step.

1.4, associative prop.

Step-by-step explanation:

because it asks for liters of total juice, you can add 0.75, 0.60, and 0.25 together then subtract 0.20. the equation can be 0.75+0.6+0.25-0.2

associative propery means no matter how you group numbers, the outcome will come out the same. for example, if we did 0.75+0.6+(0.25-0.20) and did the parenthesis first, we would get 0.75+0.6+0.05, which comes out to 1.4. hope this helped!

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
