Answer:

2⁴ *3⁵

Step-by-step explanation:

Exponents:

  •   Prime factorize 12.

        12 = 2 * 2 * 3 = 2² * 3

     12² * 3³ = (2² * 3)² * 3³

  • Apply exponent law.

         \boxed{(a*b)^m = a^m * b^m}

                    \sf = (2^2)^2*3^2 * 3^3

  •     Again, apply exponent law

        \boxed{\bf (a^m)^n = a^(m*n)}

                       \sf = 2^(2*2)*3^2*3^3\n\n= 2^4*3^2*3^3

       \boxed{\bf a^m * a^n = a^(m+n)}

                        \sf = 2^4 * 3^(2+3)\n\n =2^4* 3^5

Answer: 2⁴ * 3⁵

Step-by-step explanation:

12^2 =  ( 4 * 3)^2 = 4^2 3^2

 so you have   4^2 * 3^2 * 3^3  =

                          4^2 * 3^(2+3) =

                           4^2 * 3^5 =

                               16 * 3^5  =

                                16 *243 =3888

A car rental company charges a flat rate of $247 plus a daily rate of $53. 7)Write an equation to represent the total cost of renting a car for a certain number of days. Define your variables.

8) If you were charged $671 for renting a car, how many days did you rent the car for?

Answers

Answer:

7) C = 247 + 53d

8) 8 days

Step-by-step explanation:

7)

Let "C" represent the total cost of renting a car.

Let "d" represent the number of days the car is rented.

The equation to represent the total cost of renting a car for a certain number of days is:

C = 247 + 53d

8)

To find the number of days the car was rented when the total cost is $671, we can substitute the values into the equation and solve for "D."

671 = 247 + 53d

424 = 53d

d = 8

So, the car was rented for 8 days.

I need to know what is 140% of 15

Answers

Something percent of a number is itself*something/100

For instance, 50% of 10 is 10*50/100=10/2=5

Here, 15*(140)/(100)=21

Final answer:

140% of 15 is calculated by converting the percentage to a decimal (1.4) and then multiplying it by 15, giving a result of 21.

Explanation:

To determine 140% of 15, the process involves converting the percentage to a decimal and multiplying it by the given number. In the first step, 140% is transformed into 1.4 by dividing it by 100. Next, 15 is multiplied by 1.4. Executing this multiplication yields a final result of 21. The calculation follows a two-step procedure: conversion to a decimal and multiplication. This method ensures accurate determination of the desired percentage. In this case, the outcome of 140% of 15 is precisely 21, showcasing the systematic approach used in the mathematical computation.

In how many ways can 12 basketball players be listed in a program?A. 12

B. 479,001,600

C. 665,280

D. 1

Answers

Answer:  B. 479,001,600

Step-by-step explanation:

We know that the number of possible combination objects from a set where order matters is given by using permutations.

Given: The number of basketball players = 12

By using permutations, the number of ways the basketball players can be listed is given by :-

12!=12*11*10*9*8*7*6*5*4*3*2*1\n\n=479,001,600

Answer:

B. 479001600

Step-by-step explanation:

We are asked to find the number of ways can 12 basketball players be listed in a program.

We will use permutations to solve our given problem.

There are 12 ways to choose 1st player for the team.

Since 1 player is already chosen, so we can choose 2nd player in 11 ways. Similarly we can choose 3rd player in 10 ways.

\text{The number of ways 12 basketball players to be listed in a program}=12!

12!=12*11*10*9*8*7*6*5*4*3*2*1

\text{The number of ways 12 basketball players to be listed in a program}=479001600

Therefore, in 479001600 ways can be 12 basketball players be listed in a program and option B is the correct choice.
