Answer:
a=31
Step-by-step explanation:
1/2(a-9)=11
a-9=22
a=22+9
a=31
Alright, if I have this right, first of all, your provided with only one side of the triangle, the long leg. You need to calculate the short leg, and then the hypotenuse for it to all be complete
1. Find the short leg's measurement by dividing the length of the long leg by the square root of 3 (use a calc.)
2. 3/ the square root of 3 = to 1.73
3. The length of the short leg, supposedly, is 1.73 (roughly, was rounded)
4. Find the hypotenuse by taking the length of the short leg times 2
5. 1.73*2=3.46, (roughly, was rounded)
6. Apply the measurements to the figure.
7. The long leg is equal to 3, the hypotenuse is equal to 3.46, and the short leg is equal to 1.73
~Hope this helps!

Answer:
each barrel has a capacity of 78,75 liters
Step-by-step explanation:
since the sold 8 barrels and assuming that each have the same capacity and are sold to the same price, the total amount he earned is
total earnings = number of barrels * number of liters/ barrel * earnings/liter
R$1,260,00 = 8 barrels * number of liters/ barrel * ( R$9,00- $7,00) /liter
number of liters/ barrel = R$1,260,00/(8 barrels*R$2,00 /liter ) = 78,75 liters/barrel
therefore each barrel has a capacity of 78,75 liters
