Two friends, alejandra and mia, agreed to split the check at a restaurant. alejandra ordered $12 worth of food and mia ordered $18 worth. at the end of the meal, alejandra put her $12 contribution on the table, plus a 20% tip and mia put her $18 contribution on the table, plus a 15% tip. the total tip left by alejandra and mia is equal to r\% of the total check for their table, where the "total check" amount does not include the tip. what is r?

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
