Mary beth is making 7,763 millilters of punch she uses 3liters 26 millilters of orange juice how many liters of pinapple juice does mary beth need to add to complete her punch

Step-by-step explanation:

Total volume of punch beth is making = 7,763milliliters

If the punch contains the mixture of orange juice and pineapple juice then;

Volume of punch = Volume of pineapple juice + volume of orange juice

If she uses 3 litres 26 millilitres of orange juice.

converting the volume of orange juice to millilitres (1 litre = 1000 millilitres)

Volume of orange juice = 3000 millilitres + 26 millilitres = 3,026 millilitres

Volume of pineapple juice needed = Total volume of punch - Volume of orange juice

Volume of pineapple juice needed = 7,763 - 3,026

Volume of pineapple juice needed = 4,737millilitres

Converting the volume of pineapple to litres = 4,737/1000 = 4.737litres

The amount of liters of pineapple juice mary beth need to add to complete her punch is 4.737 litres

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
