RideAnS [48]

Answer:

0.36

Step-by-step explanation:

A= K/B^2

K= A × B^2

K= 1 × 3^2

K= 1×9

K= 9

Therefore if B is 5 then A can be calculated as follows.

K= A × B^2

9= A × 5^2

9= A × 25

9= 25A

A= 9/25

A= 0.36

Hence A is 0.36

Leo bought 50 lbs of clay for his art projects. He used 12.5 lbs to make a sculpture, and 0.72 lbs for each mug. How many mugs d
ExtremeBDS [4]

Answer:

Total number of mug = 14 mugs

Step-by-step explanation:

Given:

Total amount of Clay Leo bought = 50 lbs

Total amount of Clay left = 27.42 lbs

Total amount of Clay used in sculpture = 12.5 lbs

Amount of clay each muh need = 0.72 lbs

Find;

Total number of mug

Computation:

Assume;

Total number of mug = a

So,

Total amount of Clay Leo bought = Total amount of Clay left + Total amount of Clay used in sculpture + (Amount of clay each muh need)(Amount of clay each muh need)

50 = 27.42 + 12.5 + (0.72)(a)

50 = 39.92 + (0.72)(a)

(0.72)(a) = 10.08

a = 14

Total number of mug = 14 mugs

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
