Answer:

84

Step-by-step explanation:

we can split it into 2 cases: 1 case is when you choose the last building first and the second case is when you choose it last: so it is 4x2x2x3 for the first case and 4x3x3x1 for the last. So it’s 36+48=84 total cases.

Answer:

The percent increase in the price of the car is 31.36%.

Step-by-step explanation:

Given:

A car dealer buys a luxury car for $65,200 and sells it for $85,650.  

Now, to find the percent increase in the price of the car.

Cost price of the luxury car = $65,200.

Sell price of the luxury car = $85,650.

So, the price of the car increased by:

Sell price of the luxury car - Cost price of the luxury car.

[tex]=\$85,650-\$65,200\\\\=\$20,450.[/tex]

Thus, the price of car increased by $20,450.

Now,to get the percent increase in the price of the car:

[tex]\frac{20450}{65200} \times 100[/tex]

[tex]=0.3136\times 100[/tex]

[tex]=31.36\%.[/tex]

Therefore, the percent increase in the price of the car is 31.36%.

The period of the function [tex]y=\tan x[/tex] is equal to [tex]\pi.[/tex]

To find the exact value of [tex]\tan (6\pi)[/tex], first note that we can skip 6 periods of this function, so

[tex]\tan (6\pi)=\tan 0[/tex]

Use definition of [tex]\tan:[/tex]

[tex]\tan 0=\dfrac{\sin 0}{\cos 0}[/tex]

Since

[tex]\sin 0 = 0\\ \\\cos 0=1,[/tex]

we have that

[tex]\tan (6\pi)=\tan 0=\dfrac{\sin 0}{\cos 0}=\dfrac{0}{1}=0[/tex]

trying to find the system to the solution you have to put in into slope intersecpt form so y=mx+b

so 4=m(3)+b

12=b

y=3x+12

The question involves discovering rules for completing mathematical tables and requires skills in pattern recognition, multiplication, and data organization.

The student's question requires finding a rule for each given table and writing the missing number. Utilizing mathematical skills to recognize patterns or apply known operations is the key to solving these problems. For example, when asked about the cube of a number such as (74)³, one would have to multiply 74 by itself three times to get the result. This translates to 74 * 74 * 74, which can also be expressed as 7.4 * 102 * 7.4 * 102 * 7.4 * 102. Furthermore, when working with tables of data, it's essential to organize the data accurately and calculate additional information such as relative frequency when required.

In another instance, if you're given a list of numbers corresponding to particular data points, like the roster of students or experimental results, the task could involve identifying patterns or utilizing statistical tools to complete the tables.

It's important to show work and approach each problem methodically, confirming the application of correct mathematical rules. By doing so, you gain deeper understanding and enhance your problem-solving skills.

Answer: 200%

Step-by-step explanation:

We are asked to find the percent increase in student fees. The amount of increase in student fees is given by

final amount − initial amount = increase

12,000 − 4,000 = 8,000

We can now find the percent increase by finding what percent the amount of increase is of the initial amount. In other words, we want to find what percent 8,000 is ... of 4,000.

Let p be the percent. The question can be translated into an equation.

8,000  {is}  {what percent}     {of}  4,000

8,000  {=}   {          P          }     {x}   4,000

To solve for p, we can now divide each side by 4,000 and simplify.

8,000 = 4,000p

p=2

To convert p to a percent, multiply 2 by 100.

2 x 100

=200%

It follows that the percent increase in student fees was 200%.

Answer:

200%

Step-by-step explanation:

Find the amount of change.

12,000−4,000=8,000

Find the percent.

Change is what percent of the original amount?

Let p= the percent.

8,000 is what percent of 4,000?

Translate to an equation and simplify.

8,000 = p⋅ 4,000=

8,000 = 4,000p

Divide both sides by 4,000 and change to percent form.

2=p

200%=p

After evaluating the expression with the given values for x, y, and z by following the order of operations, the final result of the expression is 28.

To evaluate the expression given x=4, y=9, and z=7, we follow the order of operations, which means we perform the operations inside the parentheses first before multiplying by x.

First, calculate the value inside the parentheses as follows:

y + z - 3 squared

= 9 + 7 - 32

= 9 + 7 - 9

= 16 - 9

= 7

Now, multiply this result by x:

x(y + z - 3 squared)

= 4(7)

= 28

So, the evaluated expression equals 28.
