Answer:
1.58 cm
Step-by-step explanation:
Area of a square = length ²
Area of the square = 15/6 cm²
Area of a square = length ²
15/6 = length²
Find the square root of both sides
√15/6 = √length²
√2.5 = length
1.58 cm = length
Alternatively,
√15/6 = √length²
√15/√6 = length
3.87 / 2.45 = length
1.58 cm = length
Therefore, side length of the square = 1.58 cm

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

What is the volume of a right circular cone that has a height of 19 feet in a base with a diameter of 18.7 feet round your answer to the nearest 10th of a cubic foot
Answer:
A = 1739.4 cubic feet
Step-by-step explanation:
B = area of base (πr²)
h = height
A = Bh/3
A = [(18.7÷2)²π × 19] / 3
A = (9.35²π×19) / 3
A = 1739.4

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
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

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

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)

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.

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]
