Using mixed numbers, write a problem in which an estimate is enough to solve the problem.​

explain:

Estimating Differences of Fractions and Mixed Numbers

Estimating Differences of Fractions and Mixed NumbersRecall that estimation is a method for finding an approximate solution to a problem. Even when you are asked to find an exact ko, estimation is a useful way to get an idea of a reasonable solution to a problem. Once you have found an exact answer, you can check your answer against the estimate.

Ann, Bob, Carol, and Denis own a candy store. After a large argument, they decide to dissolve their partnership using the sealed
MaRussiya [10]

Answer:

Following are the solution to the given points:

Step-by-step explanation:

Ann=\$3,20,000\\\\Bob=\$4,40,000\\\\Carol=\$240,000\\\\Denis= \$4,00,000\\\\

Each player's offer divided by the total number of players calculates the fair share

Ann's fair share = \frac{\$320,000}{4} = \$80,000\\\\

Bob's fair share= \frac{\$440,000}{4} = \$110,000\\\\

 Carol's fair share = \frac{\$240,000}{4} = \$60,000\\\\

Denis's fair share = \frac{\$400,000}{4} = \$100,000\\\\

 Because Bob has the highest bid, that receives in the business.

Payments:

 Ann \$80,000 paid by estate

 Bob = \$440,000 - \$110,000 = \$330,000 owes estate

 Carol = \$60,000 paid by estate

 Denis = \$100,000 paid by estate  

Surplus = \$330,000 - (\$80,000+\$60,000+ \$100,000) = \$90,000  

Splitting the equally among the four players. therefore one of the each receives:

\frac{\$90,000}{4}= \$22,500

The final settlement of the Ann receives:

= \$80,000+ \$22,500 = \$102,500

Vlad [161]

Answer:

15.6

Step-by-step explanation:

the angle = 180-61-42=77°

x = 14.sin 77/sin 61

= 14×0.97/0.87

= 15.6
