A coach travels to the beach which is 576 KM away in 6 hours. If he is only allowed to travel at a maximum speed of 90 kph, did the coach break the speed limit? What was his average speed?

Answer:

( - 5, 1 )

Step-by-step explanation:

( [tex]\frac{x_{1} +x_{2} }{2}[/tex] , [tex]\frac{y_{1} +y_{2} }{2}[/tex] )

( [tex]\frac{-3-7}{2}[/tex] , [tex]\frac{8-6}{2}[/tex] ) = ( - 5, 1 )

Answer:

Zack wins.

Step-by-step explanation:

Vanessa's score = [tex]-3\frac{5}{8}[/tex]=-3.625

Zack's score = [tex]-3\frac{2}{3}[/tex]=-3.667

Answer: the answer is D: Comparing the decimal equivalents of their scores shows that Zack won because Negative 3.Modifying Above 6 with bar  is less than –3.625.

Step-by-step explanation:

What are the two closest square numbers to 73?

64 and 81

[tex]\sqrt{64} \leq \sqrt{73} \leq \sqrt{81}\\8\leq \sqrt{73} \leq 9\\8*9 = 72[/tex]

Answer:

72

Step-by-step explanation:

Since $73$ is between $64=8^{2}$ and $81=9^{2}$, we know that $\sqrt{73}$ is between $8$ and $9.$ Our answer is $8\cdot9=\boxed{72}.$

Answer:

The ordered pairs which are solution to given inequality are:

(0,-9)

(5,4)

Step-by-step explanation:

In order to check if the given ordered pairs are solution of the inequality or not we will put the ordered pairs one by one in the inequality.

If the inequality is holds true for the ordered pair, the ordered pair is the solution.

The inequality is:

[tex]y - 3x < -8[/tex]

So,

For (1,-5):

[tex]y - 3x < -8\\-5-3(1) < -8\\-5-3<-8\\-8<-8[/tex]

(1,-5) is not the solution of given inequality.

For (-3,-2):

[tex]-2 - 3(-3) < -8\\-2+9<-8\\7<-8[/tex]

(-3,-2) is not the solution of given inequality.

For (0,-9):

[tex]y - 3x < -8\\-9-3(0) < -8\\-9 <-8[/tex]

(0,-9) is the solution of the given inequality.

For (2,-1):

[tex]y - 3x < -8[/tex]

[tex]-1 - 3(2) < -8\\-1-3<-8\\-4<-8[/tex]

(2,-1) is not the solution of given inequality

For (5,4):

[tex]y - 3x < -8\\4 - 3(5) < -8\\4-15<-8\\-11<-8[/tex]

(5,4) is the solution of given inequality.

Hence,

The ordered pairs which are solution to given inequality are:

(0,-9)

(5,4)

1. infinitely many solutions

2. (-1,2)

3. No real solutions

The given graphs of the system of equations will have an infinite solution, unique solution and no solution, respectively.

The types of system of equations in mentioned below.

Inconsistent System

For a system of equations to have no real solution, the lines of the equations must be parallel to each other.

Consistent System

1. Dependent Consistent System

For a system of the equation to be a Dependent Consistent System, the system must have multiple solutions for which the lines of the equation must be coinciding.

2. Independent Consistent System

For a system of the equation to be an Independent Consistent System, the system must have one unique solution for which the lines of the equation must intersect at a particular.

A.) For the first graph since the lines overlap or lie on each other, therefore, the given system of equation in the first graph will be of Dependent consistent system. Thus, the system will have an infinite number of solutions.

B.) For the second graph since the lines intersect at a particular point, therefore, the given system of equations in the second graph will be an Independent consistent system. Thus, the system will have a unique solution number of solutions. Also, the solution of the equation is the point at which the lines intersect, therefore, the solution of the system of the equation will lie at (-1,2.)

C.) For the third graph since the lines are parallel to each other, therefore, the given system of equations in the third graph will be an Independent consistent system. Thus, the system will have no solutions.

0.2x + 2.7x - 8.1 = 6.9 + 1.1x

Combine like terms on left side:

0.2x + 2.7x = 2.9x

Now you have:

2.9x -8.1 = 6.9 + 1.1x

Subtract 1.1x from both sides:

1.8x - 8.1 = 6.9

Add 8.1 to both sides:

1.8x = 15

Divide both sides by 1.8:

X = 8.3333 ( round as needed) or as a fraction = 8 and 1/3

Answer:

8.3recurring

Explanation:

0.2x+2.7x =2.9x

rewrite the questions

2.9x-8.1=6.9+1.1x

like terms together. Therefore:

2.9x-1.1x = 1.8x

8.1 will go to the other side of the equal sign. Therefore:

8.1+6.9 = 15

Therefore: 1.8x = 15

x =15/1.8 which is equal to 8.3recurring

The unit price in dollars per orange is $ 4. 2

A unit price is the price for a given commodity or service that includes all extra costs attached to the item.

It is described as the product's average price.

It is determined by dividing the product's total sales revenue by the total units sold for the product.

It is known as the price per unit of the product.

From the information given, we have that;

$3.84 for a bag of 16 oranges

The unit price;

= 16/3. 84

Divide the values

= $4. 166

=$ 4. 2

Hence, the value is $ 4. 2

Answer: B. f(x)=(x+4)(x-2)^2(x+3)

Step-by-step explanation:

in the graph there's two negative x value and one positive x value

so the function should be in a form of f(x)= (x+a) (x-b)^2 (x+c)

the one with negative value has a square, (x-b)^{2}, because that's where the y = 0 (the point is hitting the (x,0))

Answer: B

Step-by-step explanation:

Answer:

y=3/4x-11

Step-by-step explanation:

When a line is perpendicular to another line, their slope is the opposite reciprocal of that. So in this case, the slope of the perpendicular line would be positive 3/4. Next, plug in the points (8,-5) in the y=mx+b formula along with the new slope. In conclusion, the new point slope formula is y=3/4x-11.

The number of modes in the dataset is 1. The dataset is unimodal. The correct option is therefore;

1 mode

A unimodal data is a set of data that has only one mode. The mode is a measure of central tendency.

The data in the question can be presented as follows;

Kate, Tim, John, John, Angelam, Tim, Sue

The frequency of each of the data is therefore;

Kate; 1, Tim; 1, John; 2, Angela; 1, Tim; 1, Sue; 1

The mode of a dataset, is the value that has the highest frequency, or that appears the most in the dataset.

The data that has the highest frequency is John, the mode of the dataset is therefore, John, which has a frequency of 1
