You times 12 and 41 and then times your answer with Another 41 and add them together
Answer:
Your Answer is $43.7
Step-by-step explanation:
Take the initial $38 and Multiply it by the .15 (15%) tip
You get a $5.7 tip
Add that to the meal cost of $38 and you get $43.7
Your 50 feet below sea level and then you go up 10 feet 5 times so the answer would be -10
Let and be the amounts of available alloy (AA) and pure magic steel that are used, so we also have
DA13 is supposed to contain 7% gold, 3% silver, and 90% steel, so that 2.7 kg of it is made up of
For each kg of the available alloy (AA), there is a contribution of 0.21 kg of gold, 0.09 kg of silver, and therefore 0.70 kg of steel; kg of it will contain kg of gold, kg of silver, and kg of steel. Each kg of magic steel of course contributes 1 kg of steel; kg of it will contribute kg of steel.
Then the dwarves need
• total gold:
• total silver:
• total steel:
Solve for and . The first two equations are consistent and give , and substituting this into the third we find . So the dwarves must combine 0.90 kg of AA and 1.80 kg of magic steel.
