Marsha and Tian are making table decorations for a party. Marsha made 2/9 of a decoration in half and hour. Tian made 2/3 of a decoration in the same amount of time. How much more of a decoration did Tian make in a half and hour? How much would they make in a half hour if they worked together?

...

Step-by-step explanation:

4/9 and 8/9

Step-by-step explanation: you have to have a common denominator so you take 3 and 9 and find what they both go into and that number is 9 so take 2/3 and times the top and bottom by 3 to get 6/9 and 2/9 by 1 to get 2/9 once you have those subtract them to get 4/9 and that's your first answer then take them and add so you get 8/9 which is your second answer

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
