Answer:
The correct selections are A and B.
Step-by-step explanation:
The picture depicted above can be represented as [tex]5w+4=99[/tex], since 5 times something plus 4 is the same as 99. In choice a, Andre babysat 5 times and earned the same amount of money each time, so you could represent that by [tex]5w[/tex]. Since he received an extra $4 and earned a total of 99 dollars, the first choice is correct. In choice B, the family of 5 paid the same amount for each ticket, which can be represented by [tex]5w[/tex]. Since they paid $4 for parking and paid a total of $99, choice B can also be represented by the picture, which means it's correct.

9. The population of a certain animal species increases at a rate of 6.5% per year. There are currently
counted 120 of the animals in the habitat you are studying
Which function will model the expected change in the animal population from this point forward?
Answer:
FV= PV*(1 + g)^n
Step-by-step explanation:
Giving the following information:
Present Value (PV)= 120
Growth rate (g)= 6.5% per year
To calculate the future value of the population in any given year "n", we need to use the following formula:
FV= PV*(1 + g)^n
For example, in 10 years:
FV= 120*(1.065^10)
FV= 225

The correct answer is 0 or A
Step-by-step explanation:
2/0+2 + 1/5 = 6/0+5
2/2 + 1/5 = 6/5
1 + 1/5 = 6/5
5/5 + 1/5 = 6/5

A room is thrice as long as the breadth. It contains 270m^3 of air and the cost of painting its four walls at Rs 15 per m^2 is Rs. 3600, find the cost of carpeting the floor at Rs. 98 per m^2.
Answer: ₹2646
Step-by-step explanation:
Given
The volume of the room is [tex]V=270\ m^3[/tex]
cost of painting the walls is ₹[tex]3600[/tex] at the rate of [tex]15\ m^2[/tex]
So, the area of walls is
[tex]\Rightarrow A=\dfrac{3600}{15}\\\\\Rightarrow A=240\ m^2[/tex]
This the area of 4 walls i.e.
[tex]\Rightarrow 240=2[hl+hb]\\\Rightarrow 120=h[l+b]\\\Rightarrow 120=4bh\quad [\text{length is thrice of width}]\\\Rightarrow 30=bh\qua \ldots(i)[/tex]
The volume of the room is given by
[tex]V=l\times b\times h\\270=3b\times b\times h\\90=hb^2\quad \ldots(ii)[/tex]
Divide (i) and (ii)
[tex]\Rightarrow \dfrac{90}{30}=\dfrac{b^2h}{bh}\\\\\Rightarrow b=3\ m[/tex]
So, the length of the room is
[tex]l=3b\\l=3\times 3\\l=9\ m[/tex]
The area of the floor is
[tex]\Rightarrow A_o=l\times b\\\Rightarrow A_o=9\times 3\\\Rightarrow A_o=27\ m^2[/tex]
The cost of flooring is
[tex]\Rightarrow 27\times 98\\\Rightarrow Rs.2646[/tex]

I'm asking you, please, a little help.
this is area right???
Answer:
Yes
Step-by-step explanation:
So permiter is two*lengths plus 2*width of a shape.
Area is the length times the width.
For examplel if a square has a length of 2, and a width of 3 the permiteter is:
2*2+3*3=
4+9
=
13
On the other hand, area would be:
2*3

Complete the square to find the vertex of this parabola. x2-16y-4x-12=0
Answer:
Step-by-step explanation:
x^2-16y-4x-12=0
Transpose and separate x and y
16y = x^2-4x-12
16y = (x^2-4x+4) -16
16y = (x-2)^2 -16
y = (1/16)(x-2)^2 -1
This means that the vertex is at
(x-2)=0 or x=2
y = -1
=> vertex (2,-1)

What is Equation of line?
The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The graph is shown in figure.
Two points on the graph are (2, 6) nd (3, 9).
Now,
Solve for the correct rule of the graph as;
Since, The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
So, We find the slope of the line as;
Two points on the graph are (2, 6) and (3, 9).
Hence,
m = (9 - 6) / (3 - 2)
m = 3/1
m = 3
Thus, The equation of line in point-slope form passing through the points (2, 6) and (3, 9).with slope 3 is defined as;
⇒ y - y₁ = m (x - x₁)
⇒ y - 6 = 3 (x - 2)
⇒ y - 6 = 3x - 6
⇒ y = 3x
Thus, The correct rule for the graph shown will be;
⇒ y = 3x

The simplified expression √2 x √10 / √5 is 2.
To simplify the expression √2 x √10 / √5, we can combine the square roots and apply the properties of radicals.
First, let's simplify the numerator, which is √2 * √10.
√2 x √10 = √(2 x 10) = √20
Next, let's simplify the denominator, which is √5.
So, √20 / √5
To rationalize the denominator, we multiply both the numerator and denominator by √5:
= (√20 / √5) x (√5 / √5)
= √(20 x 5) / √(5 x 5)
= √100 / √25
= 10 / 5
= 2
Therefore, the simplified expression is 2.

Last week, Ann bought 9 books and 5 movies for a total of $124.
Today, Ann bought 4 books and 21 movies for a total of $318.
Assuming neither item has changed in price, what is the cost of a book in dollars?
Answer:
$6
Step-by-step explanation:
Set up a system of equations where b is the cost of a book and m is the cost of a movie:
9b + 5m = 124
4b + 21m = 318
Solve by elimination by multiplying the top equation by -21 and the bottom equation by 5:
-189b - 105m = -2604
20b + 105m = 1590
Add the equations together, then solve for b:
-169b = -1014
b = 6
So, the cost of a book is $6
Use the table to describe the locations of the zeros of the quadratic function $f$ .
The zeros are between _ and_ , and between_ and_ .
Answer:
The zeros are between -4 and -3, and between 0 and 1
Step-by-step explanation:
Here, we want to location of the zeros
As we can know, at the zeros of a quadratic function, the y value at those point is zero
So whenever we have y value being zero, we have it that the x value at that point is a zero or root of the quadratic function
Now, looking at the table, we can see that between the point x = -4 and -3; y moved from -2 to 2
For this movement to occur, we must have passed through 0 as we have -1 ,0 and 1 between the numbers as -2 and 2
So obviously, the root is between -4 and -3
Secondly as we can see, f(x) moved from 2 to -2
The numbers between here are 1 , 0 and -1
So definitely the root lies between the x values of 0 and 1
