Just add them all:(FYI, I first converted all the mixed fraction to improper)
11/3+19/3= 30/3+9/2
Now take out the LCM,
60/6+27/6= 87/6
Hence, the total number of cups that peter makes is 87/6
1.5kg is 1500 grams.
Maria uses 50g a day, so to know how many days takes eating the whole packet just divide 1500 by 50.
Using the definition of the tangent function, you can find ...
... FA = DF·tan(30°) = (7√3)·(1/√3) = 7
Then the usual formula for triangle area can be used:
... Area = (1/2)bh = (1/2)·(7√3)(7)
... Area = (49/2)√3 square units
... ≈ 42.44 square units
3 feet are in one yard
so 3 ×10 =30
so 30 ÷ 7 = 4.2
Answer is 4
even is there if there is a decimal only 4 can be made
