For Thursday's English class, 4 students are assigned to give presentations. How many different ways can the
teacher order the student presentations?
4 ways
16 ways
24 ways
7 ways
The teacher ordered the students in 24 ways.
We have given that the total number of students is 4.
4 students are assigned to give presentations.
We have to find the arrangement of the 4 students.
What is the arrangement?
An arrangement (or ordering) of a set of objects is called a permutation. (We can also arrange just part of the set of objects.)
In a permutation, the order that we arrange the objects n is important.
4 students can be arranged by 4! ways.
[tex]4!=4*3*2*1\\ =12*2\\=24[/tex]
Therefore option 3 is correct.
The teacher ordered the students in 24 ways.

Using the together rate, it is found that they would prepare the solution in 1.71 minutes working together.
What is the together rate?It is the sum of each separate rate.
In this problem, the rates are given by:
Johanna's: 1/6.Elizabeth's: 1/6.Dan's: 1/4.Hence the together rate is given by:
[tex]\frac{1}{x} = \frac{1}{6} + \frac{1}{6} + \frac{1}{4}[/tex]
[tex]\frac{1}{x} = \frac{1}{3} + \frac{1}{4}[/tex]
[tex]\frac{1}{x} = \frac{4 + 3}{12}[/tex]

Write the equation for the line in slope-intercept form.
Answer:
y=[tex]\frac{2}{3}x[/tex]+4
Step-by-step explanation:
[tex]\frac{rise}{run}[/tex]
plus the y intercept
which is 4
The required equation in slope-intercept form is y = - [tex]\frac{2}{3}[/tex]x + 4
What is an equation?An equation represents any two expressions or statements are equal that means they are having an equal to (=) sign in brtween them.
What is slope intercept form?The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept is called slope-intercept form of the equation.
How to find the slope ?Slope of a line is the inclination of the straight line towards x axis.
If a straight line passes through two points (a , b) and (c , d), then slope(m) of the straight line can be calculated by the formula,[tex]m = \frac{d - b}{c-a}[/tex]
According to the problem, the straight line passes through (6 , 0) , (3 , 2) , (0, 4) , (-3 , 6).
Slope (m) = [tex]\frac{2-0}{3-6}[/tex] = - [tex]\frac{2}{3}[/tex]
How to write the equation in slope-intercept form?The equation can be written as
y = - [tex]\frac{2}{3}[/tex]x + b
Now , this line passes thorugh (0,4). So, (0,4) will satisfy the equation∴ putting (0,4) in the equation, we get,
y = 4
∴ The required equation is y = - [tex]\frac{2}{3}[/tex]x + 4.
For check we can satisfy the point ( -3 , 6) in the equation.- [tex]\frac{2}{3}[/tex](-3) + 4 = 6
CLearly, the point satisfies the equation.
So, the equation y = - [tex]\frac{2}{3}[/tex]x + 4 is correct

Write an equation of the line that passes through the point (6,-9) with the given slope m= 3
Answer:
y = 3x - 27
Step-by-step explanation:
Since the slope is three, that is the only one that can be the answer.
answer: y = 3x - 27
explanation:
equation of a straight line: y = mx + c
( m is the slope and c the y- intercept )
here m = 3 , then y = 3x + c ← is the partial equation
to find c substitute (6, - 9) into the partial equation
-9 = 18 + c ⇒ c = -9 - 18 = - 27
y = 3x - 27 ← equation of line

Answer:

Step-by-step explanation:
Given:
Mike is buying eight tickets for a concert.
A package of five tickets costs $74.45.
Individual tickets cost $17.25 each.
To Find:
What is the least amount that Mike can pay for eight tickets? Be sure to include a decimal point in your answer.
Solve:
Since we know that:
A package of five tickets costs $74.45.
Individual tickets cost $17.25 each.
Hence we know that 5 + 3 = 8
Thus,
$74.45 = 5 tickets
Now for the 3 tickets we can do individual tickets which cost $17.25
$17.25 × 3 = 51.75
Then we add both together:
51.75 + 74.45 = $126.20

Group of answer choices
225°
235°
Based on the information provided, the sum of all the labeled angles is 235° (option b).
How to calculate the sum of all labeled angles?To calculate the sum of all the labeled angles we must add the different values of each labeled angle as shown below:
80° + 92° + 40° + 23° = 235°
According to the above, it can be inferred that the correct option is B because the result of the sum of the values coincides with this sum.
