Joey Chestnut is trying to break his own record for eating the most whole hot dogs in 101010 minutes. He needs to eat more than
anygoal [31]

Answer:

9d+11\frac{1}{4}>72

Step-by-step explanation:

We are supposed to write an inequality to determine the number of hot dogs per minute Joey must eat for the last 9 minutes to break his record.

Let d represent the number of hot dogs Joey eats per minute for the next 9 minutes.

We have been given that after 1 minute, Joey has eaten 11\frac{1}{4} hot dogs.

Hot dogs eaten in next 9 minutes would be 9 times d that is 9d.

Total hot dogs eaten by Joey would be hot dogs eaten in 1 minute plus next 9 minutes: 9d+11\frac{1}{4}.

Since to break the record Joey needs to eat more than 72 hot dogs. We can represent this information in an inequality as:

9d+11\frac{1}{4}>72

Therefore, our required inequality would be 9d+11\frac{1}{4}>72.

Anita is years older than Basilio. Three times Anita's age added to six times Basilio's age is 36. 1. Define the variables 2. Cr
Scilla [17]

Answer :Anita's age = 7 years

Basilio's age = 2.5 years

Step 1. Assign variables to Anita's and Basilio's ages.

Anita's age = A

Basilio's age = B

 

Step 2. Use the information given to form two equations.

Anita is 4-1/2 years older than Basilio

A = 4.5 + B

 

Three times Anita's age added to six times Basilio's age is 36

3A + 6B = 36

 

Step 3. Substitute the value of A from first equation in to the second equation and solve for B

3(4.5 + B) + 6B = 36

13.5 + 3B + 6B = 36

13.5 + 9B = 36

9B = 36 - 13.5

9B = 22.5

B = 22.5/9 = 2.5

 

Step 4. Find the value of A

A = 4.5 + 2.5 = 7

 

Answer:

Anita's age = 7 years

Basilio's age = 2.5 years

What is a simpler form of the radical expression?<br><br> SOMEONE PLEASE HELP!!
Brilliant_brown [7]

Answer:

Choice B

Step-by-step explanation:

Given radical expression:

\sqrt[4]{1296 {x}^{16}  {y}^{12} }

To Find:

The Simpler form of this expression

Soln:

=  \sqrt[4]{1296 {x}^{16}  {y}^{12} }

We could re-write the given expression, according to the law of exponents:

=  \tt \sqrt[4]{(6x {}^{4}y {}^{3})  {}^{4}  }

Now we need to bring terms out of the radical as:

\tt =   | 6x { }^{4} y {}^{3}  |

Bring out 6x^4 from the absolute & put y^3 only in it:

\tt = 6x {}^{4}  |y {}^{3} |

Choice B is accurate.
